It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.Clinical Coding: Process of substituting a symbol or code for a term such as a diagnosis or procedure. (from Slee's Health Care Terms, 3d ed.)Collagen Diseases: Historically, a heterogeneous group of acute and chronic diseases, including rheumatoid arthritis, systemic lupus erythematosus, progressive systemic sclerosis, dermatomyositis, etc. This classification was based on the notion that "collagen" was equivalent to "connective tissue", but with the present recognition of the different types of collagen and the aggregates derived from them as distinct entities, the term "collagen diseases" now pertains exclusively to those inherited conditions in which the primary defect is at the gene level and affects collagen biosynthesis, post-translational modification, or extracellular processing directly.

(Adams et al., Principles of Neurology, 6th ed, p903)Optic Nerve: The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI.

Although markedly similar to large-cell immunoblastic lymphoma (LYMPHOMA, LARGE-CELL, IMMUNOBLASTIC), this group's unique features warrant separate treatment.Neoplasms, Second Primary: Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.Neoplasms: New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.Melanoma: A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445)Choroid Neoplasms: Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid.

It occurs in dry and wet forms.Geographic Atrophy: A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.Stem Cell Transplantation: The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.Retinal Drusen: Colloid or hyaline bodies lying beneath the retinal pigment epithelium. They may occur either secondary to changes in the choroid that affect the pigment epithelium or as an autosomal dominant disorder of the retinal pigment epithelium.Cell- and Tissue-Based Therapy: Therapies that involve the TRANSPLANTATION of CELLS or TISSUES developed for the purpose of restoring the function of diseased or dysfunctional cells or tissues.Stem Cells: Relatively undifferentiated cells that retain the ability to divide and proliferate throughout postnatal life to provide progenitor cells that can differentiate into specialized cells.Diagnosis-Related Groups: A system for classifying patient care by relating common characteristics such as diagnosis, treatment, and age to an expected consumption of hospital resources and length of stay.

Intercellular junctions in the ciliary epithelium. (1/1033)

The fine structure of the intercellular junctions in the ciliary epithelium of rhesus monkeys and rabbits was studied with conventional electron microscopy of thin-sectioned specimens and the freeze-fracturing technique. In the rhesus monkey, a zonula occludens, zonula adhaerens, gap junctions, and desmosomes interconnect the nonpigmented cells, whereas gap junctions, puncta adhaerentia, and desmosomes connect pigmented to nonpigmented cells, and pigmented cells to one another. In the rabbit, desmosomes are absent between nonpigmented cells, and substituted for by puncta adhaerentia. The zonula occludens between nonpigmented cells greatly varies in its complexity in different regions of the cell perimeter, and in places, it may consist of very few intramembrane strands; this suggests that the ciliary epithelium is relatively leaky to ions and small molecules. Gap junctions are ubiquitous in the ciliary epithelium and particularly numerous at the interface between pigmented and nonpigmented layers; this finding indicates that the cells of the ciliary epithelium are joined in a metabolic syncytium. All gap junctions are characterized by the crystalline configuration which is typical of the uncoupled state; furthermore, in specimens fixed by immersion, they may be caused by uncoupling and take place in the time interval elapsing between interruption of the blood supply and arrival of the fixative fluid. Puncta adhaerentia resemble zonulae adhaerentes in their structural details but are macular in shape instead of encompassing the cell perimeter in a beltlike fashion. In contrast with desmosomes, the intercellular cleft of puncta adhaerentia has an irregular width and contains opaque material, but this never gives rise to the central band typical of desmosomes. On the inner aspect of the junctional membranes, there is a layer of fluffy material but no plaque of insertion for a bundle of tonofilaments. Finally, puncta adhaerentia have no representation in the interior of the plasmalemma and are intimately associated with cytoplasmic microfilaments. They probably anchor to the plasmalemma the contractile apparatus of the ciliary epithelial cells.  (+info)

Microvascular loops and networks as prognostic indicators in choroidal and ciliary body melanomas. (2/1033)

BACKGROUND: Malignant melanoma of the ciliary body and choroid of the eye is a tumor that disseminates frequently, and 50% of the diagnosed patients die within 10 years. We investigated the hypothesis that, by histopathologic analysis of the arrangement of microvessels (i.e., small blood vessels) in loops and networks, we might be able to differentiate better those patients with a favorable prognosis from those with a poor prognosis. METHODS: We conducted a population-based, retrospective cohort study of melanoma-specific and all-cause mortality for 167 consecutive patients who had an eye surgically removed because of malignant choroidal or ciliary body melanoma during the period from 1972 through 1981. Microvascular loops and networks were evaluated independently by two pathologists who were unaware of patient outcome. RESULTS: Microvascular patterns could be assessed in 134 (80%) of 167 melanoma specimens. The 10-year probability of melanoma-specific survival was worse if microvascular loops (0.45 versus 0.83; two-sided P<.0001) and networks (0.41 versus 0.72, two-sided P<.0001) were present. In multivariate Cox regression analysis of melanoma-specific survival, the hazard ratios were 1.66 (95% confidence interval [CI] = 1.19-2.30) for the presence of loops and networks as a combined three-category variable, 2.36 (95% CI = 1.37-4.05) for the presence of epithelioid cells, 1.11 (95% CI = 1.03-1.19) for the largest basal tumor diameter (evaluated as a continuous variable), and 2.14 (95% CI = 1.25-3.67) for ciliary body involvement. CONCLUSIONS: Patients with malignant uveal melanoma who have a favorable prognosis can be distinguished from those with a poor prognosis by histopathologic analysis of microvascular patterns in uveal melanoma tumor specimens.  (+info)

Hyaluronan synthase expression in bovine eyes. (3/1033)

PURPOSE: Hyaluronan (HA), a high-molecular-weight linear glycosaminoglycan, is a component of the extracellular matrix (ECM). It is expressed in eyes and plays important roles in many biologic processes, including cell migration, proliferation, and differentiation. Hyaluronan is produced by HA synthase (HAS), which has three isoforms: HAS1, HAS2, and HAS3. In this study, the HAS expression in the anterior segment of bovine eyes was investigated to determine the significance of HA in eyes. METHODS: To obtain bovine HAS probes, degenerate oligonucleotide primers, based on well-conserved amino acid sequences including the catalytic region of each HAS isoform, were used for reverse transcription-polymerase chain reaction to amplify mRNA from bovine corneal endothelial cells (BCECs). Hyaluronan synthase-1 expression in the anterior segment of bovine eyes at the protein level was investigated by immunohistochemistry. RESULTS: All three HAS isoforms were expressed in BCECs at the mRNA level. Amplified cDNA fragments of HAS1, HAS2, and HAS3 from BCECs can be aligned to human counterparts, showing similarities of 100%, 97.3%, and 100%, respectively, at the amino acid level. Hyaluronan synthase 1 was expressed at the protein level in corneal epithelium, keratocyte, corneal endothelium, conjunctival epithelium, ciliary epithelium, capillary endothelium, and trabecular meshwork. CONCLUSIONS: Hyaluronan synthase isoforms were expressed in the ocular anterior segment and are speculated to be involved in HA production in situ.  (+info)

Latrunculin-A causes mydriasis and cycloplegia in the cynomolgus monkey. (4/1033)

PURPOSE: To determine the effect of latrunculin (LAT)-A, which binds to G-actin and disassembles actin filaments, on the pupil, accommodation, and isolated ciliary muscle (CM) contraction in monkeys. METHODS: Pupil diameter (vernier calipers) and refraction (coincidence refractometry) were measured every 15 minutes from 0.75 to 3.5 hours after topical LAT-A 42 microg (approximately 10 microM in the anterior chamber [AC]). Refraction was measured every 5 minutes from 0.5 to 1.5 hours after intracameral injection of 10 microl of 50 microM LAT-A (approximately 5 microM in AC), with intramuscular infusion of 1.5 mg/kg pilocarpine HCl (PILO) during the first 15 minutes of measurements. Pupil diameter was measured at 1 and 2 hours, and refraction was measured every 5 minutes from 1 to 2 hours, after intravitreal injection of 20 microl of 1.25 mM LAT-A (approximately 10 microM in vitreous), with intramuscular infusion of 1.5 mg/kg PILO during the first 15 minutes of measurements (all after topical 2.5% phenylephrine), and contractile response of isolated CM strips, obtained <1 hour postmortem and mounted in a perfusion apparatus, to 10 microM PILO +/- LAT-A was measured at various concentrations. RESULTS: Topical LAT-A of 42 microg dilated the pupil without affecting refraction. Intracameral LAT-A of 5 microM inhibited miotic and accommodative responses to intramuscular PILO. Intravitreal LAT-A of 10 microM had no effect on accommodative or miotic responses to intramuscular PILO. LAT-A dose-dependently relaxed the PILO-contracted CM by up to 50% at 3 microM in both the longitudinal and circular vectors. CONCLUSIONS: In monkeys, LAT-A causes mydriasis and cycloplegia, perhaps related to its known ability to disrupt the actin microfilament network and consequently to affect cell contractility and adhesion. Effects of LAT-A on the iris and CM may have significant physiological and clinical implications.  (+info)

A3 adenosine receptors regulate Cl- channels of nonpigmented ciliary epithelial cells. (5/1033)

Adenosine stimulates Cl- channels of the nonpigmented (NPE) cells of the ciliary epithelium. We sought to identify the specific adenosine receptors mediating this action. Cl- channel activity in immortalized human (HCE) NPE cells was determined by monitoring cell volume in isotonic suspensions with the cationic ionophore gramicidin present. The A3-selective agonist N6-(3-iodobenzyl)-adenosine-5'-N-methyluronamide (IB-MECA) triggered shrinkage (apparent Kd = 55 +/- 10 nM). A3-selective antagonists blocked IB-MECA-triggered shrinkage, and A3-antagonists (MRS-1097, MRS-1191, and MRS-1523) also abolished shrinkage produced by 10 microM adenosine when all four known receptor subtypes are occupied. The A1-selective agonist N6-cyclopentyladenosine exerted a small effect at 100 nM but not at higher or lower concentrations. The A2A agonist CGS-21680 triggered shrinkage only at high concentration (3 microM), an effect blocked by MRS-1191. IB-MECA increased intracellular Ca2+ in HCE cells and also stimulated short-circuit current across rabbit ciliary epithelium. A3 message was detected in both HCE cells and rabbit ciliary processes using RT-PCR. We conclude that human HCE cells and rabbit ciliary processes possess A3 receptors and that adenosine can activate Cl- channels in NPE cells by stimulating these A3 receptors.  (+info)

Higher proportions of type C than of types A and B natriuretic peptide receptors exist in the rat ciliary body. (6/1033)

We investigate the interaction of atrial natriuretic peptide (ANP) brain natriuretic peptide (BNP) and C-type natriuretic peptide (CNP) with their receptors (NPRA, NPRB and NPRC), as well as the proportion and localization of those receptors in the rat ciliary body. Binding assays and affinity cross-linking experiments demonstrated the presence of the NPRC receptor type. However, the three natriuretic peptides stimulate the guanylate cyclase activity in the ciliary body membranes suggesting the presence of the NPRA and NPRB receptor type. Microautoradiographic data show that the NPRs are localized in the whole ciliary body. Our results indicated that NPRC is the most prominent receptor type in this tissue.  (+info)

Dendritic cells and macrophages in the uveal tract of the normal mouse eye. (7/1033)

BACKGROUND/AIMS: Dendritic cells (DC) and macrophages are components of the immune cell populations in the uveal tract whose density, distribution, turnover, and function may play a role in the maintenance of immunological homeostasis in the eye. Little is known of these cells in the mouse eye despite this being the predominant experimental model in many studies of ocular immune responses and immunoinflammatory mediated eye diseases. The aim of the present study was to obtain further immunophenotypic data on resident tissue macrophages and DC populations in the mouse uveal tract. METHODS: Pieces of iris, ciliary body, and choroid dissected from perfusion fixed BALB/c mice were incubated whole in a variety of anti-macrophage and DC monoclonal antibodies (mAbs). Labelled cells were visualised using either single or double immunoperoxidase techniques. RESULTS: Quantitative analysis and double immunolabelling revealed that 80% of F4/80(+) cells (a mAb that recognises both DC and macrophages) in the iris are macrophages (SER4(+)). The iris contained a network of Ia+ cells (412 (SD 130) cells/mm2) of which two thirds appear to be DC. A similar pattern was observed in the ciliary body and choroid. Only a few DC in the uveal tract were very weakly reactive for mAbs which recognise B7-1 (CD80), B7-2 (CD86), beta2 integrin (mAb N418), and multivesicular bodies associated with antigen presentation (mAb M342). CONCLUSIONS: The present study reveals that the mouse uveal tract, like the rat, contains rich networks of DC and resident tissue macrophages. The networks of resident tissue macrophages in the mouse uveal tract closely resemble similar networks in non-ocular tissues. The phenotype of uveal tract DC suggests they are in the "immature" phase of their life cycle, similar to Langerhans cells of the skin, thus implying their role in situ within the eye is antigen capture and not antigen presentation.  (+info)

Age-related changes in human ciliary muscle and lens: a magnetic resonance imaging study. (8/1033)

PURPOSE: To use high-resolution magnetic resonance (MR) images of the eye to directly measure the relationship between ciliary muscle contraction and lens response with advancing age. METHODS: A General Electric, 1.5-Tesla MR imager and a custom-designed eye imaging coil were used to collect high-resolution MR images from 25 subjects, 22 through 83 years of age. A nonmagnetic binocular stimulus apparatus was used to induce both relaxed accommodation (0.1 diopter [D]) and strong accommodative effort (8.0 D). Measurements of the ciliary muscle ring diameter (based on the inner apex), lens equatorial diameter, and lens thickness were derived from the MR images. RESULTS: Muscle contraction is present in all subjects and reduces only slightly with advancing age. A decrease in the diameter of the unaccommodated ciliary muscle ring was highly correlated with advancing age. Lens equatorial diameter does not correlate with age for either accommodative state. Although unaccommodated lens thickness (i.e., lens minor axis length) increases with age, the thickness of the lens under accommodative effort is only modestly age-dependent. CONCLUSIONS: Ciliary muscle contractile activity remains active in all subjects. A decrease in the unaccommodated ciliary muscle diameter, along with the previously noted increase in lens thickness (the "lens paradox"), demonstrates the greatest correlation with advancing age. These results support the theory that presbyopia is actually the loss in ability to disaccommodate due to increases in lens thickness, the inward movement of the ciliary ring, or both.  (+info)

In the current study, our results demonstrated that the IκB/NF-κB signaling pathway was involved in the expression and activation of MMP-2 in human ciliary muscle cells. Downregulation of IκBα by siRNA resulted in significant translocation of NF-κBp65 from the cytoplasm to the nucleus after 24 h to 72 h. The secretion of MMP-2 increased as well as the activation from pro-MMP-2 to active-MMP-2. In addition, the expression of MT1-MMP increased while the expression of TIMP-2 reduced both in mRNA and protein levels. It is implied from these results that NF-κB is an important transcriptional factor involved in the control of uveoscleral outflow through the promotion of MMP-2 expression. It has been reported that NF-κB is involved in various activities and plays a key role in multiple biological processes including chemical stress, physical stress, physiologic stress, receptor ligands, proinflammatory cytokines, and apoptosis. At the same time, there are also multiple and complex signal ...

Cytoplasmic pH was measured by imaging microscopy using the pH-sensitive dye BCECF (2′,7′-bis(2-carboxyl)-5(6)-carboxyfluorescein-acetoxyethyl ester). To load the cells with BCECF, NPE cells grown to semiconfluence on a 35-mm plastic dish (Corning Costar, Corning, NY) were incubated for 10 minutes with BCECF-AM (5.0 μM) as described earlier. 24 Then, the cells were washed five times with the Krebs solution and incubated for another 10 minutes in Krebs solution to allow de-esterification of the dye. De-esterification transforms BCECF-AM (the ester form) to membrane-impermeable BCECF (acid form), which is trapped in the cytoplasm. The cells were then washed again several times to remove any traces of external dye. The dish containing the cells was then placed in a temperature-controlled perfusion microincubator (PDMI-2; Harvard Biosciences, Holliston, MA) on the stage of an upright epifluorescence microscope (Eclipse; Nikon, Tokyo, Japan) where the preparation was superfused (3.0 mL · ...
Ciliary body medulloepithelioma is an intraocular neoplasm derived from the primitive ciliary body medullary epithelium, which forms the non-pigmented ciliary body epithelium. First described in histologic detail by Verhoeff in 1904, this unusual lesion was named "teratoneuroma" [1]. Fuchs in 1908 coined the term of "diktyoma" [1]. However, Grinker later on identified the cellular origin of the tumor by naming it "medullopithelioma" in 1931 [2]. Without any hereditary or racial predisposition, this childhood tumor is the second most common intraocular primary malignancy, following primary intraocular retinoblastoma [3]. Its exact population based incidence is undetermined because it is a very rare neoplasm [4]. Based on the incidence of retinoblastoma, which has been reported to be around 4.1 per million in the United States, we can infer that the incidence of medulloepithelioma is significantly lower [5]. The average onset of this disease is 4 years of age, with diagnosis typically in the first ...

To assess the biotransformational capability of ocular tissues in the rabbit, representative phase II enzymes were assayed in five tissues from the eye, and in the liver, kidney, and intestine. Within the eye, the iris/ciliary body exhibited the highest glutathione S-transferase activity, whereas the cornea possessed the highest specific activities for N-acetyl-, sulfo-, and UDP-glucuronosyl-transferases. Cornea, iris/ciliary body, choroid, and retina exhibited significant activities of p-aminobenzoic acid N-acetyltransferase, 2-naphthol sulfotransferase, and 1-chloro-2,4-dinitrobenzene glutathione S-transferase. Despite its size and protein content, lens displayed little or no biotransformational activity. Only the iris/ciliary body conjugated sulfobromophthalein with glutathione. UDP-glucuronsyltransferase activity varied depending on tested substrates and tissues. When compared to liver, kidney, or intestine, N-acetyltransferase activity in the iris/ciliary body nearly matched the rate ...

Glaucoma is a serious disease associated with increased intraocular pressure which often leads to blindness. One of the ways to treat glaucoma is to reduce aqueous humour secretion in the ciliary body of the eye by suppressing (inhibiting) activity of special enzymes - carbonic anhydrases. Russian scientists from RUDN University have designed new compounds that can effectively reduce intraocular pressure by isoform selective inhibiting human carbonic anhydrase. The results of the study were published in the prestigious Bioorganic Chemistry journal.
Pvrl3 encodes a cell adhesion protein that is required for the formation of cell-cell junctions in neurons and other cell types (Takai et al., 2003b). Mutations in this gene are associated with congenital ocular defects in the lens and ciliary body in humans (Lachke et al., 2012). Pvrl3-deficient mice have microphthalmia and defects in cell adhesion between the pigmented and non-pigmented ciliary epithelial cells of the eye (Inagaki et al., 2005). Lamination is normal in the Pvrl3-deficient mouse retina, and it has been proposed that the microphthalmia is a secondary effect of perturbations in the formation of vitreal humor due to the defects in the ciliary epithelium (Inagaki et al., 2005). Cep192 orchestrates a signaling cascade that is required for centrosome maturation and bipolar spindle assembly during mitosis (Kim and Dynlacht, 2013). Downregulation of Cep192 in Brg1-deficient retinae might perturb the coordination of interkinetic nuclear migration and the timing of S-phase and M-phase in ...
Treatment for glaucoma is directed at restoring both vision and comfort. This requires an accurate assessment of the extent and duration of the pressure elevation. In eyes which have the potential for return of functional vision (no globe enlargement, duration less than one week), immediate medical therapy is used to initially reduce the pressure. This is followed by a choice of surgical options to attempt to permanently normalize the pressure. Medical management is rarely successful long-term due to recurrent pressure elevation and drug toxicity.. The diode laser is used to treat glaucoma through photocoagulation of the ciliary body. A 1 mm probe is applied to the sclera 2-2.5 mm posterior to the limbus to deliver 2.5-3.5 joules (2.5 mwatts for 1000-1400 msec) of energy to the ciliary body over 20-30 sites. This results in localized destruction of the secretory epithelium of the ciliary body thus reducing aqueous humor production. There is also some increase in extrascleral outflow of aqueous ...
Purpose : MicroRNAs (miRNAs) are small, noncoding strands of RNA that negatively regulate post-transcriptional gene expression. Since miRNAs have been associated with many eye diseases, many studies have tried to profile the mammalian ocular miRNAs using microarray and realtime PCR. Our study aims to profile ocular miRNA expression in normal human eye tissue using miRNA-Seq. Methods : Total RNAs were extracted from normal human ciliary body (CB) (n=2), cornea (n=2), retina (n=2), and trabecular meshwork (TM) (n=4) samples using mirVana total RNA isolation kit from Life Technologies. We used 1 µg RNA from each sample to prepare sequencing library with Illumina TruSeq Small RNA Library Prep kit with sample-specific indexes. Pooled libraries were sequenced using Illumina MiSeq. Generated sequence reads were trimmed and aligned against human reference database using Bowtie software. Only exact matches to known mature miRNA sequences were counted. The resulting miRNA profile was analyzed and ...

For advanced or aggressive cases of open-angle glaucoma, the patient may be advised to undergo a Laser Cyclophotocoagulation. This procedure is usually conducted when other treatments have proven unsuccessful. This surgery targets the ciliary body within the eye-the part of the eye responsible for production of fluid. If the ciliary body is not functioning properly, the pressure in the frontal portion of the eye will not drain, resulting in glaucoma. An ophthalmologist cuts part of the ciliary body so that it will make less fluid and reduce eye pressure. This procedure is performed under local anesthesia and is followed up with exams to monitor eye pressure and inflammation.. ...

ICD-10 C69.40 is malignant neoplasm of unspecified ciliary body (C6940). This code is grouped under diagnosis codes for neoplasms.
ECP is a new technique that reduces the amount of fluid (aqueous humor) produced in the eye and thus lowers pressure within the eye (intraocular pressure or IOP). This can help patients suffering from glaucoma, a disease where excess fluid puts pressure on the optic nerve and damages vision.. ECP is often performed at the same time as cataract surgery for patients who suffer from both cataracts and glaucoma. Recent studies show that patients who undergo the combined ECP/cataract surgery need fewer glaucoma medications over the long term.. During an ECP procedure, the ophthalmologist inserts a tiny probe with a fiber optic light at the tip into the part of the eye that produces fluid, known as the ciliary body or ciliary process. Laser energy then damages some of these cells so they stop producing fluid. The result is a lower, healthier pressure within the eye. Many patients who undergo ECP will sometimes no longer need eyedrops or other glaucoma medications after treatment.. Dr. Allaman has been ...

Meshed parts were then imported into LS-DYNA (LSTC, Livermore, CA) following assembly using LSPREPOST (LSTC). Contacts were defined for each part-to-part contact as follows. The lens to zonules, zonules to ciliary body, ciliary body to sclera, and sclera to cornea were attached sequentially. This contact type ties the nodes and outer segments of the two parts together at the contact interface so that the displacements of adjacent tissues must be equal. Failure of the contact was not modeled at these attachments. Contacts between the vitreous and all other structures, retina and all other structures, and aqueous and all other structures were modeled allowing a failure criterion to be defined at the contact junction. Due to a lack of knowledge of the specific failure thresholds for these junctions in the physical eye, the failure values were set to a level thought to be above reported physiological failure levels of the tissues, with the exception of the retina-to-sclera junction; this contact ...
Cyclophotocoagulation - One of the ways to treat glaucoma is to decrease the amount of fluid production in the eye from the cells that make the fluid. Ciliary body treatments use either a cryoprobe (a freezing probe) or a laser to treat cells that make the fluid in the eye. These procedures cause the cells to decrease their usual production. The G-Probe is a non-invasive fiber-optic laser handpiece specially designed for the selective ablation of ciliary processes. G-Probe treatment is repeatable and is performed in the operating room. ...

Weve been instructed that there are several surgical treatments that may prolong vision and help with fluid and pressure reduction. We are still in the process of researching these procedures to see what we want to do. Currently, we are at a point where we could opt to treat her bad eye with one of these surgical procedures, but have decided not to due to her loss in vision. One option is to place a shunt in her eye that would help drain fluid, which has an average success rate of 25% after 1 year and of course a risk of blindness from the surgery. Additionally, the shunt could cause irritation and other issues. This procedure runs around $3,500. Another option we are looking into is Endoscopic cyclophotocoagulation (ECPC), which also comes with risks such as cataracts, blindness, and retinal detachment. With this procedure, the lens is removed and small incision is made. With a laser, they blast the ciliary bodies that produce the aqueous humor (the fluid). There is another laser surgery where ...

This study provides a detailed description of immunolocalization of two oxygen-binding proteins, neuroglobin (Ngb) and cytoglobin (Cygb), in the anterior segment of healthy human and canine eyes. Specific antibodies against Ngb and Cygb were used to examine their distribution patterns in anterior segment structures including the cornea, iris, trabecular meshwork, canal of Schlemm, ciliary body, and lens. Patterns of immunoreactivity (IR) were imaged with confocal scanning laser and conventional microscopy. Analysis of sectioned human and canine eyes showed Ngb and Cygb IR in the corneal epithelium and endothelium. In the iris, Ngb and Cygb IR was localized to the anterior border and the stroma, iridal sphincter, and dilator muscle. In the iridocorneal angle, Ngb and Cygb were detected in endothelial cells of the trabecular meshwork and canal of Schlemm in human. In the ciliary body, Ngb and Cygb IR was localized to the non-pigmented ciliary epithelium of the pars plana and pars plicata and in ciliary
24 cases of Schwartz Matsuo syndrome are described in the literature from 1970 until now.

Our patient presented with a non post-traumatic retinal detachment without oral dialyses or tears in the nonpigmented epithelium of the ciliary body. The signs disappeared after surgery but the retinal detachment recurred twice and at the end it was associated to a macular hole.. Back to previous ...
AIM: To investigate the infiltration and activation of lymphocyte in iris-ciliary body and anterior chamber after allogenic penetrating keratoplasty (PK), for further revealing the role of iris-ciliary body in corneal allograft immune rejection. METHODS: In the mice models of PK, BALB/C mice received orthotopic isografts (n =35) or C57BL/6 donor allografts (n =25). Grafts were examined daily for 3 weeks by slit-lamp microscopy and scored for opacity. The infiltration of CD4(+) T lymphocyte in iris-ciliary body and anterior chamber was examined by immunohistology and the mRNA of CD80 and CD86 in both cornea graft and iris-ciliary body by RT-PCR was analyzed in allograft recipient at days 3, 6, 10 and the day when graft rejection occurred. Isograft recipients were examined as control at the corresponding time points. Transmission electron microscope was used to study the ultrastructure, especially cell infiltration, of iris-cilary body and corneal graft at day 3, 7 and the day when rejection ...

Diktyoma, or ciliary body medulloepithelioma, or teratoneuroma, is a rare tumor arising from primitive medullary epithelium in the ciliary body of the eye. Almost all diktyomas arise in the ciliary body, although, rarely, they may arise from the optic nerve head or retina. The name "diktyoma" comes from its characteristic findings on histology. Diktyoma is classified into teratoid and nonteratoid types, based on heteroplastic tissue in the former. Each type may be sub-classified as benign or malignant based on histology. Based on histology, the tumor is classified as malignant if it contains poorly differentiated neuroblasts, nuclear pleomorphism, markedly abnormal mitotic activity, sarcomatous components, or invasion into the uvea, cornea, or sclera. Most diktyomas are malignant. The most common symptoms of diktyoma are vision loss and pain, while the most common signs are leukocoria and presence of a mass in the iris or ciliary body. Other signs and symptoms include lens subluxation, glaucoma, ...

Brinzolamide is a highly specific, non-competitive, reversible carbonic anhydrase inhibitor. Carbonic anhydrase (CA) is an enzyme found in many tissues of the body including the eye. It catalyzes the reversible reaction involving the hydration of carbon dioxide and the dehydration of carbonic acid. In humans, carbonic anhydrase exists as a number of isoenzymes, the most active being carbonic anhydrase II (CA-II). Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. The result is a reduction in intraocular pressure. Brinzolamide is indicated in the treatment of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.
There is still, however, considerable local and regional variation in the use of this treatment (anecdotal impressions suggest that it is used more commonly and earlier for glaucoma treatment in the United Kingdom than in the United States), perhaps in part because of the relative paucity of high quality laboratory and clinical studies demonstrating if, why, and how it is effective. There is even less evidence concerning endoscopic cyclophotocoagulation (ECP), the more refined but less widely available cousin of TSCP.. In the April issue of the BJO, Lin et al published an important laboratory based study that adds to our understanding of the clinical effects and complications of cyclophotocoagulation (CP).2 They have attempted to quantify the evolution of vascular changes following CP; their results demonstrate that both TSCP and ECP are associated with an acute occlusive vasculopathy, but that with the endoscopic modality the chronic underperfusion is less than with the transscleral ...
A retrospective analysis was made of the first 19 eyes of 19 patients with intractable glaucoma treated with contact diode cyclophotocoagulation. We assessed intraocular pressure (IOP) and number of glaucoma medications. The mean follow-up was 4 months (range 1 to 11 months). Mean IOPs decreased from 31.7 +/- 14.6 pre-diode treatment to 23.7 +/- 16.9 mmHg at the last follow-up visit after treatment (p = 0.02). The mean number of medications required decreased from 1.9 before to 1.3 after treatment (p = 0.03). The study suggests that diode cyclophotocoagulation is an effective and safe procedure in eyes with refractory glaucoma ...
The functional changes in the ciliary body in presbyopia are not only important in a study of the mechanism for presbyopia but are also a key to various procedures or devices used to restore accommodation. Therefore, it is becoming increasingly important to quantify the in vivo accommodative changes in the aging ciliary muscle with and without a lens. We are going to evaluate the changes in the pilocarpine-induced contractility of the ciliary muscle in eyes with presbyopia before and after cataract extraction using ultrasound biomicroscopy (UBM).UBM will be performed with and without instilling 2 % pilocarpine, as well as before and 2 months after cataract extraction.

In the anterior part of our eye there are two cavities filled with a watery but nutritive fluid called aqueous humor. One cavity, called the anterior chamber, lies just behind the cornea and in front of the iris. The other, called the posterior chamber, is a narrow space behind the iris and is surrounded by a mucsuloepithelial structure called the ciliary body. Aqueous humor is contiuously formed into the posterior chamber by the double layer ciliary epithelium that covers the ciliary body. Aqueous humor then sips through the hole at the center of iris, called the pupil, into the anterior chamber. Excess aqueous humor leaves the anterior chamber, by a pressure dependent way, mainly through a sieve-like structure called the trabecular meshwork located at the junction of the cornea and the sclera. Apart from supplying the nutrients and removing metabolic wastes from the avascular tissues of the eye, namely, the cornea, trabecular meshwork and the lens, the aqueous humor maintains the optimum ...

Glaucoma is one of the most common reasons for blindness. Usually an elevated drain resistance is the reason, while aqueous humor production is normal. Medical reduction of intraocular pressure (IOP) is first line therapy in most cases. The gold standard of surgical treatment still is trabeculectomy (TE) but TE has a lot of drawbacks. In particular when glaucoma and cataract coexists, the investigators therefore prefer the combined procedure cataract extraction plus excimer laser trabeculotomy (ELT) or plus Trabectome. Indication is cataract and a moderate elevated IOP without medical therapy or a moderate cataract and elevated IOP with medical therapy.. The ELT is performed by an AIDA XeCl-Excimer Laser System (TUI-Laser AG, Germering, 1,2 mJ per burst, burst duration 16 ns, wave length 308 nm, spot diameter 200 µm). 10 foramina were made over 90 degrees of the anterior chamber angle. Trabectome procedure is performed with the Trabectome unit from Neomedix.. ...
We are excited to announce that the Ophthalmology Service recently purchased a novel device to treat glaucoma.. The equipment uses newly patented MicroPulse technology to deliver laser energy and lower intra-ocular pressure. Compared to previous laser units, the MicroPulse device provides a kinder, gentler approach with an improved efficacy and safety profile. While standard cyclophotocoagulation creates focal burns in the ciliary body, this novel device revolutionizes the procedure by "chopping" continuous laser waves into repetitive short pulses, thereby avoiding focal heating and burning of the tissue. This technique results in a slow, steady application of laser energy to the ciliary body.. The device can be used in dogs, cats and horses, and is a good option for patients for which medical therapy for glaucoma has become ineffective. It is also beneficial for patients with early disease as an adjunctive treatment for elevated intra-ocular pressure.. ...
The pars plana (Latin: flat portion) is part of the ciliary body in the uvea (or vascular tunic), the middle layer of the three layers that comprise the eye. As a part of the ciliary body, it is about 4 mm long, located near the point where the iris and sclera touch and is scalloped in appearance. The pars plana may not have a function in the post-fetal period, making this a good site of entry for ophthalmic surgery of the posterior segment (pars plana vitrectomy ...

The chick embryo has prevailed as one of the major models to study developmental biology, cell biology and regeneration. From all the anatomical features of the chick embryo, the eye is one of the most studied. In the chick embryo, the eye develops between 26 and 33 h after incubation (Stages 8-9, Hamburger and Hamilton, 1951). It originates from the posterior region of the forebrain, called the diencephalon. However, the vertebrate eye includes tissues from different origins including surface ectoderm (lens and cornea), anterior neural plate (retina, iris, ciliary body and retinal pigmented epithelium) and neural crest/head mesoderm (stroma of the iris and of the ciliary body as well as choroid, sclera and part of the cornea). After gastrulation, a single eye field originates from the anterior neural plate and is characterized by the expression of eye field transcriptional factors (EFTFs) that orchestrate the program for eye development. Later in development, the eye field separates in two and the
... is a serious disease that causes inflammation of the eye. "Uveitis" refers to general inflammation of a portion of the eye, usually just the front of the eye. In panuveitis, however, both the front and the back of the eye are affected. The affected region is known as the uveal tract, which is composed of the iris, the choroid, and the ciliary body. The iris is the colored back of your eye that controls the size of your pupil. The choroid is the inner lining of the eye that contains blood vessels. The ciliary body produces fluid to keep your eye moist. All of these structures are important for vision, and inflammation of these components can cause visual problems. The cause of panuveitis is generally unknown, but there are some links to other diseases such as syphilis, sarcoidosis, toxoplasmosis, and tuberculosis. Some other possible causes may include infections, tumors, bruises, and toxins in the eyes. The main symptoms of panuveitis are eye pain, blurred vision, vision loss, light ...

Anterior uveitis is an inflammation of the middle layer of the eye, which includes the iris (colored part of the eye) and adjacent tissue, known as the ciliary body. If untreated, it can cause permanent damage and loss of vision from the development of glaucoma, cataract or retinal edema. It usually responds well to treatment; however, there may be a tendency for the condition to recur. Treatment usually includes prescription eye drops, which dilate the pupils, in combination with anti-inflammatory drugs. Treatment usually takes several days, or up to several weeks, in some cases.. Anterior uveitis can occur as a result of trauma to the eye, such as a blow or foreign body penetrating the eye. It can also be a complication of other eye disease, or it may be associated with general health problems such as rheumatoid arthritis, rubella and mumps. In most cases, there is no obvious underlying cause.. Signs/symptoms may include a red, sore and inflamed eye, blurring of vision, sensitivity to light ...

As an army sergeant (and later lieutenant) in World War II, he was transferred to the Valley Forge General How to buy Tadagra cheap in Phoenixville, Pennsyl- vania. 642 Conclusions PDS is characterized by release pigmented epithelium of the iris or ciliary body, or both, particularly in the midperipheral region in both eyes, with an attendant deposition of pigment on intraocular structures such as the back of the cornea, the trabecular meshwork, the iris.
Conventional treatment options include eye drops, laser therapy (especially for the narrow angle variety) and surgery, and are required if the patient continues to lose peripheral vision (tested by visual field exams).. The fluid pressure between the iris and the cornea builds up because the trabecular meshwork (the filter on the eyes drainpipe) becomes unable do its job properly. This is a bit more complex than it sounds. Recent evidence shows that there is a functional relationship between the ciliary body, which pulls, and the trabecular meshwork, which then distends and blocks fluid outflow. Originally thought to be a passive participant, it now seems that the trabecular meshwork itself has the ability to contract and open itself for fluid drainage (Wiederholt et al., 2000).. The goal of internal herbal therapy is to preserve visual function and maintain the health of the optic nerve. The ideal medicine for glaucoma should improve microcirculation to the back of the eye, nourish and ...

The uvea is the major blood supply to the eye and is comprised of the iris, ciliary body, and choroid. These major structures of the eye are very sensitive and perform numerous functions required for ocular homeostasis and vision. Uveitis is inflammation of these structures and results in pain, cloudiness to the intraocular fluids, and in severe cases, blindness. Uveitis can occur for many reasons, and depending on what the ophthalmologist finds on your pets examination, they may be able to determine the most likely cause. Further diagnostics with blood tests, radiographs, or ultrasounds may be recommended. In severe cases with pain that is unresponsive to therapy, surgery may also be recommended.. ...
Eye. Artwork of a section through a healthy human eyeball. Light passes through the cornea (grey arch, centre left), the eyes main light-focusing structure. The iris (wavy pink structures, centre left) contracts or relaxes to allow the ideal amount of light through the pupil, the central hole of the iris. The light is finely focused by the lens (pale blue oval, centre left), which hangs from the ciliary body, before hitting the retina (dark pink, centre) that lines the inside of the eyeball. The light-sensitive cells in the retina convert the light into a nerve signal that passes along the optic nerve (green, centre right) to the brain for processing. - Stock Image P424/0135

The NCCN Guidelines for Uveal Melanoma include recommendations for staging, treatment, and follow-up of patients diagnosed with uveal melanoma of the choroid or ciliary body. In addition, because distinguishing between uveal melanoma and benign uveal nevi is in some cases difficult, these guidelines also contain recommendations for workup of patients with suspicious pigmented uveal lesions, to clarify the tests needed to distinguish between those who should have further workup and treatment for uveal melanoma versus those with uncertain diagnosis and low risk who should to be followed and later reevaluated. These NCCN Guidelines Insights describe recommendations for treatment of newly diagnosed nonmetastatic uveal melanoma in patients who have already undergone a complete workup. ...

1. Histological examination of sections of the eyes and joints of large numbers of rabbits injected with hemolytic streptococci has clearly demonstrated that when arthritis or cyclitis occurs, the synovial villi and ciliary processes are the most frequent and usually the primary sites of inflammation.. 2. By special methods for demonstration of bacteria, it has been shown that bacteria which found lodgement in either an eye or a joint were demonstrable first in the vessels of ciliary processes or synovial villi.. 3. A localized synovitis or iridocyclitis is brought about by the localization of bacteria in the synovial villus and ciliary process.. 4. These experiments, which give a clearer insight into the pathogenesis of infectious arthritis and iritis, explain why both may occur in association with certain infectious diseases.. ...
BOCA RATON, FL, March 12, 2014 - 21st Century Television will feature Oculus, Inc., a medical equipment company specializing in the anterior eye, in an upcoming segment of the shows Health feature. President and CEO of Oculus, Michael Wolber, is interviewed by 21st Century Televisions Jackie Bales. Wolber discusses the importance of eye screening as it relates to proper treatments. He states that the worst thing that a patient can do is conduct inadequate research. Wolber goes on to say that, "These days there are several options, but not every option is suitable for every patient." Ten years ago Oculus created the Oculus Pentacam, which enables doctors to see the entire anterior eye segment located in front of the vitreous humour. The anterior eye segment is comprised of the cornea, iris, ciliary body, and lens. The Oculus Pentacam allows doctors to conduct early screening for abnormalities that would make their patients candidates for refractive eye and cataract surgery. The Oculus Pentacam ...
This study examined the ocular actions of an opioid agonist. Experiments were performed to evaluate the effects of DPDPE ([D-pen2, D-pen5] enkephalin), a delta opioid agonist on: 1) intraocular pressure (IOP) in rabbits; 2) cAMP accumulation in rabbit iris ciliary bodies (ICBs); 3) 3H-norepinephrine (NE) overflow from electrically stimulated sympathetic nerves in ICBs. DPDPE Lowerd IOP in normal rabbits but not in sympathectomized (SX) eyes. Naloxone did not inhibit the effect of DPDPE on IOP in normal rabbits. DPDPE inhibited 3H-NE overflow and suppressed cAMP accumulation in ICBs. The presence of naltrindole, a delta receptor antagonist, did not prevent the suppression of cAMP levels by DPDPE. Pertussis toxin (PTX) did not prevent the inhibition of cAMP levels by DPDPE. The data suggest that the lowering of IOP by DPDPE is mediated at both pre- (neuronal) and postjunctional (ciliary body) sites and may involve an atypical opioid receptor. In addition, the actions of DPDPE in the anterior segment may
AIMS: To evaluate the effects of allopurinol in lens induced uveitis (LIU) by morphological methods and to compare these effects with those of steroids and a combination of both drugs biochemically and morphologically. METHODS: Lipid peroxides (LPO) of the retinal tissue were determined by two different methods (thiobarbituric acid assay (TBA) and high performance liquid chromatography expressed as malondialdehyde-like substances). Myeloperoxidase (MPO) activity in the iris/ciliary body complex was analysed spectrophotometrically. Histological changes on three morphological levels of LIU eyes were evaluated. RESULTS: Both allopurinol and the combination of allopurinol/prednisolone led to a significant reduction in the increaed retinal LPO values. Prednisolone only revealed significant effects on retinal LPO when being measured with the TBA method. MPO activity in iris and ciliary body was significantly reduced in all therapy groups. The morphological evaluation of the sections by two masked ...
Uveitis is a provocative methodology including the center of the three layers in the eye. To comprehend uveitis it is vital to know the fundamental life structures of the eye. The external layer encasing the eye is made out of the acceptable cornea and the white sclera. The deepest layer is the nerve layer or the retina. The center layer is the uveal tract, which is rich in veins. It is made out of the iris in the front some piece of the eye, the ciliary body, which generates the liquid (fluid diversion) inside the eye, and the choroid which sustains the retina in the once again of the eye. Due to its rich blood supply, the uveal tract is a common focus for infections beginning in different parts of the body. At the point when aggravation strike particular portions of the uveal tract, the sickness is further delegated iritis (irritation of the iris), cyclitis (irritation of the ciliary body) or choroiditis (aggravation of the choroid), contingent upon the influenced structure. In the event that ...
The goal of this project is to obtain quantitative images of the lens and the ciliary body to validate EVAS-II (Second generation Ex Vivo Accommodation Simulator). To accomplish this goal it was necessary to develop methods, instrumentation and image processing techniques to acquire 3D images in EVAS-II, using UBM (Ultrasound Bio Microscope), and to apply these techniques to non-human primate eyes. The lens studies included measurement of speed of sound in the lens to reconstruct accurate images of the lens, development of instrumentation to measure the un-distorted lens shape and development of a mathematical model to quantify the whole lens shape. Speed measurements showed that the speed of sound exhibits a gradient profile in the equatorial plane, similar to refractive index and protein distributions in the lens. Lens shape measurements showed that the UBM can be used to accurately measure thickness, diameter, cross-sectional area, volume and surface area of the lens. The ciliary body studies
Light rays come off an object in all directions, as they result from the light around us from sun, moon and artificial light bouncing back off the object. The part of this bounced light that come into the eye from an object needs to be focused on a small area of the retina. If this doesnt happen, what we look at will be blurred.. The cornea and lens have the job of focusing light. The cornea does most of the work, as it (refracts) the light rays which then go through the lens, which finely adjusts the focusing. The lens does this by changing its thickness. This is called accommodation. The lens is elastic and can become flatter or more rounded. The more rounded (convex) the lens, the more the light rays can be bent inwards.. The shape of the lens is varied by the small muscles in the ciliary body. Tiny string-like structures called the suspensory ligaments are attached at one end to the lens and at the other to the ciliary body. This is a bit like a trampoline with the central bouncy bit being ...
DONT SKIP THIS ORIENTATION!!!! - You will save time in the long run.. There are three Tunic (Coats) of the Eye. From the outside inward they are the Fibrous Tunic (Tunica Fibrosa cosisting of the Cornea & Sclera), the Vascular Tunic (Tunica Vasculosa, Uvea, Choroid), and the Tunic Interna (Retina). All three of the tunics or coats are considered to be a complete covering of the eye (except for the pupillary opening). So if you follow the sclera forward from the posterior eye (around the periphery) you pass into the limbus (corneo-scleral junction) and the cornea. The anterior continuation of the choroid (vascular; tunic) becomes the ciliary body and stroma (front) of the iris. The retina is the innermost coat of the eye and is a sensory layer posterior to the Ora Serrata. The retina continues anteriorly as an epithelium two cells thick covering the Ciliary Processes (the Ciliary Retina) and the back of the Iris (The Iridial Retina). This anterior extension of the retina is not sensory, and ...

... occurs when there is active inflammation originating from the uveal tract of the eye. The uveal tract includes: the iris, the ciliary body, and the choroid. Inflammation can occur in the eye for many reasons. A common reason is that the bodys immune system becomes confused and sends inflammatory cells to attack parts of ones own body (in this case, the uveal tissue). Another cause could be an infection inside the eye, such as from a virus, bacteria, or fungus.. Patients with active uveitis may complain of light sensitivity, redness, and blurry vision.. Uncontrolled inflammation in the eye can cause significant problems including the potential for vision loss and blindness. Complications from uveitis include swelling of the retina (macular edema), low or high eye pressure (glaucoma), retinal detachment, and scar tissue formation. Treatment of uveitis is recommended to thwart these complications. Treatment may include topical steroid eyedrops, shots of steroids inside or around the eye, ...
The aqueous humor is a clear fluid that maintains the integrity of the eye. It is produced by the ciliary body and passes through the trabecular meshwork and Schlemms canal. Intraocular pressure (IOP) is determined by the amount of aqueous humor secreted, coupled with the rate of clearance from the eye. An elevated IOP leads to optic nerve deterioration and associated irreversible functional vision loss.[1][2]

The oculomotor nerve is responsible for several parasympathetic functions related to the eye. The oculomotor PSN fibers originate in the Edinger-Westphal nucleus in the CNS and travel through the superior orbital fissure to synapse in the ciliary ganglion located just behind the orbit (eye). From the ciliary ganglion, the postganglionic PSN fibers leave via short ciliary nerve fibers, a continuation of the nasociliary nerve (a branch of ophthalmic division of the trigeminal nerve, CN V1). The short ciliary nerves innervate the orbit to control the ciliary muscle (responsible for accommodation) and the sphincter pupillae muscle, which is responsible for miosis or constriction of the pupil (in response to light or accommodation) (Netter and Hansen 2003).. The parasympathetic aspect of the facial nerve controls secretion of the sublingual and submandibular salivary glands, the lacrimal gland, and the glands associated with the nasal cavity. The preganglionic fibers originate within the CNS in the ...

N2 - Volume-activated Cl- channels (VACCs) play vital roles in many cells including cholangiocytes. Previously, we characterized the VACCs in mouse cholangiocytes. Since calcium plays an important role in VACC regulation in many cells, we have studied the effect of calcium modulation on the regulatory volume decrease (RVD) and VACC currents in mouse bile duct cells (MBDCs). Cell volume measurements were assessed by a Coulter counter with cell sizer, and conventional whole-cell patch-clamp techniques were used to study the role of calcium on RVD and VACC currents. Cell volume study indicated that MBDCs exhibited RVD, which was inhibited by 5-nitro-2′-(3-phenylpropylamino)- benzoate (NPPB), 4,4′-diisothiocyanostilbene-2,2′-disulfonate (DIDS) and 1,2-bis(o-aminophenoxy)ethane-N,N,N′,N′-tetraacetic ...

In the present study, Argon laser photocoagulation showed a good prognosis similar to surgical direct cyclopexy in small-size cyclodialysis cleft below 1.5 clock-hours. No significant differences in preoperative and postoperative clinical characteristics were shown between Argon laser photocoagulation group and surgical direct cyclopexy group. Given that the Argon laser photocoagulation is simpler and less expensive than surgical direct cyclopexy, Argon laser photocoagulation would be a better treatment of choice in small-size cyclodialysis cleft.. When the extent of the cyclodialysis cleft is not large, it is possible to wait for spontaneous recovery using conservative treatment. Previously, several reports suggested that conservative medical treatment was effective in small-size cyclodialysis cleft. Ormerod et al. reported that 1 % atropine can help to close the cleft by relaxation of the ciliary muscle to sclera [13]. Joondeph et al. suggested that abrupt cessation of steroid can make ...
