Hyaluronan synthase expression in bovine eyes. (1/421)

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)

Anterior polar cataracts in CS rats: a predictor of mature cataract formation. (2/421)

PURPOSE: The objective of this study was to characterize the morphology of the anterior opacities formed during recovery from posterior subcapsular cataract (PSC) in Royal College of Surgeons (RCS) rats. METHODS: Lenses from RCS rats at 8 and 12 weeks postnatal (n = 14 and 12, respectively) were examined under a dissecting microscope for the presence of anterior opacities. Lenses with anterior opacities were fixed, embedded in epoxy resin, and sectioned along the optic axis for light microscopy (LM) and transmission electron microscopy (TEM). RESULTS: At eight weeks postnatal, 21.5% of animals (3/14) had anterior cataracts. Light microscopy of 1- to 2-microm-thick sections revealed an anomalous layer of material located at the epithelium-fiber interface, which was identified as a zone of liquefaction by TEM. Epithelial cells had minor structural defects but were not necrotic. Anterior portions of elongating and cortical fibers under the zone of liquefaction were undisrupted, whereas their posterior portions had numerous vacuoles. The anterior opacities were classified as anterior polar cataracts (APCs) based on the location and type of morphologic damage in the affected lenses. At twelve weeks postnatal, 25% of animals (3/12) had APCs that involved prominent vesiculation of the anterior cortex. Ultrastructural examination showed that large vesicles were located between and inside anterior fibers and that most extracellular spaces were abnormally widened. Posteriorly, internalization of the PSC by new fiber growth was disordered and displayed vesiculation and density variations. In the bow region, LM revealed minor structural irregularities that were identified as groups of apparently degenerating fibers by TEM. CONCLUSIONS: APCs in RCS rats are caused by degeneration of elongating fibers in the bow region and subsequent damage in the superficial anterior cortex. The percentage of animals with APCs (25%) was consistent with the percentage of animals in which mature cataracts eventually develop. The morphologic changes, time of onset, and percentage of animals affected suggest that APC is the initial manifestation of mature cataract formation in RCS rats.  (+info)

Normal development of refractive state and ocular component dimensions in the marmoset (Callithrix jacchus). (3/421)

Refractive state and ocular dimensions were studied longitudinally in nine normal marmosets. Animals were anaesthetised and examined (with some exceptions) at 4, 6, 7, 8, 10, 15, 24 and 39 weeks of age. Cycloplegic retinoscopy showed that hyperopia early in life rapidly diminished. Refraction corrected for the artefact of retinoscopy stabilised by 8 weeks of age, but at a slightly myopic value, rather than at emmetropia. The ocular components continued to change throughout the period studied. Corneal radius, measured by photokeratometry, increased slightly during development. Anterior segment depth and vitreous chamber depth (VCD), measured by A-scan ultrasonography, increased throughout development while lens thickness initially increased and then decreased. Data from the eyes of these normal animals were compared with that from the contralateral eyes of animals which received short periods of monocular deprivation early in life (Troilo, D., & Judge S.J. (1993). Ocular development and visual deprivation myopia in the common marmoset (Callithrix jacchus jacchus). Vision Research, 33, 1311-24); eyes which viewed through no lens or a plano lens (Graham, B. & Judge, S.J. (1999)). The effects of spectacle wear in infancy on eye growth and refractive error in the marmoset (Callithrix jacchus). Vision Research, 39, 189-206), and eyes of normal animals in another colony. There were no significant differences between the first two groups and the normal animals in our colony while age-matched animals from the other colony were slightly but significantly less myopic than our animals.  (+info)

High-resolution ultrasonic imaging of blood flow in the anterior segment of the eye. (4/421)

PURPOSE: To develop a noninvasive technique to visualize and measure blood flow in the iris and ciliary body. METHODS: Echo data from 50-MHz ultrasound scans of the iris and ciliary body of rabbits were digitized using a new "swept scan" modality. The method makes use of spatial oversampling to identify regions with scatterers whose range changes with time. The data allowed construction of high-resolution B-mode images with embedded flow information. Pulsatility over the cardiac cycle was evaluated by sending a series of pulses along a single line of sight containing a vessel of interest. Local blood flow and changes over the cardiac cycle before and after application of atropine were quantified. RESULTS: Flow was identified in the radial vessels and major arterial circle of the iris. Vessels with lumens as small as 40 microm in diameter and flow velocities as low as 0.6 mm/sec were measured. Change in blood velocity over the cardiac cycle was determined to be approximately 27%. Peak systolic velocity after administration of topical atropine increased by 72%. CONCLUSIONS: This technique allowed visualization of flow using the same type of very-high-frequency transducer now widely used for imaging the anterior segment. The technique can also be used at lower frequencies for more posterior tissues with similar improvement of resolution over Doppler. The ability to examine flow in the anterior segment of the eye offers a new tool for study of glaucoma, hypotony, tumors, and other disorders.  (+info)

Effects of UV-A radiation on lens epithelial NaK-ATPase in organ culture. (5/421)

PURPOSE: To investigate the mechanisms involved in the damage caused by UV-A irradiation at 365 nm on the eye lens. METHODS: Bovine lenses obtained from animals 1 to 5 years of age were placed in specially designed organ culture chambers for preincubation. Twenty-four hours later, the lenses were irradiated by 33 J/cm2 UV-A at 365 nm. During irradiation, the lenses were oriented in the culture so that the anterior surface faced the incident UV-A radiation source. After irradiation, lens optical quality was monitored throughout the 8 days of the culture period, and lens samples were taken for analysis of NaK-ATPase activity. RESULTS: Lens optics and NaK-ATPase activity were affected by irradiation of 33 J/cm2. The effects on lens epithelial NaK-ATPase activity were stronger at the equators than at the center. The damage to the activity at the center was reversible, as the lens optically recovered from the LW-A damage. CONCLUSIONS: Lens NaK-ATPase activity can recover from damage caused by UV-A at 365 nm. When the lenses received irradiation of 33 J/cm2, NaK-ATPase activity recovered from the damage during the culture period only at the center and not at the equators of the epithelium.  (+info)

Hydraulic pressure stimulates adenosine 3',5'-cyclic monophosphate accumulation in endothelial cells from Schlemm's canal. (6/421)

PURPOSE: Fluid flow across various endothelia results in a variety of intracellular and extracellular adaptations. In the living eye, aqueous humor flows across the surface of endothelial cells on trabecular meshwork (TM) beams and in the juxtacanalicular tissue and through or between a continuous monolayer of endothelial cells that line Schlemm's canal (SC). This study was undertaken to test the hypothesis that fluid flow induces biochemical changes in the endothelial cells of the outflow pathway that may modify outflow resistance. METHODS: Trabecular meshwork and SC cells isolated from the outflow pathway of human cadaveric eyes were seeded onto porous filters, placed in Ussing-type chambers, and subjected to fluid flow driven by a pressure head of 15 mm Hg on their apical surface. Cell lysates were prepared and analyzed for adenosine 3',5'-cyclic monophosphate (cAMP) accumulation. Barrier function of cell monolayers was examined using transendothelial electrical resistance measurements. RESULTS: Three different SC cell strains in 14 independent experiments responded with at least a threefold increase in cAMP that was both time and pressure dependent. Conversely, flow-treated TM cells failed to respond in six independent experiments in which five different TM cell strains were used. Electrical resistance across cell monolayers positively correlated with cAMP accumulation and was calcium sensitive. CONCLUSIONS: cAMP signaling is affected by pressure differentials across SC cell monolayers and provides evidence for the participation of SC cells in the regulation of aqueous outflow.  (+info)

Effects of experimental ocular inflammation on ocular immune privilege. (7/421)

PURPOSE: To determine whether the inflammation of endotoxin-induced uveitis (EIU) and experimental autoimmune uveoretinitis (EAU) alters key in vivo and in vitro parameters of ocular immune privilege. METHODS: For EIU induction, C3H/HeN mice received 200 microg lipopolysaccharide (LPS). For EAU induction, B10.A mice were immunized with 50 microg interphotoreceptor retinoid-binding protein (IRBP) mixed with complete Freund's adjuvant. Aqueous humor (AqH) was collected at periodic intervals and assayed for leukocyte content and the ability to suppress or enhance T-cell proliferation. Eyes with EAU were assessed for the capacity to support anterior chamber (AC)-associated immune deviation (ACAID) induction after injection of ovalbumin (OVA). RESULTS: Inflammation within the anterior segment in EIU peaked at 12 to 24 hours and was detected from 10 days onward in EAU. In AqH of EIU, protein content rose within 4 hours, followed by infiltrating leukocytes. EIU AqH promptly lost its capacity to suppress T-cell proliferation and became mitogenic for T cells. In AqH of EAU, protein and leukocyte content rose at 11 days and continued to remain elevated thereafter. Whereas 11-day EAU AqH failed to suppress T-cell proliferation, AqH at later time points reacquired immunosuppressive properties. Injection of OVA into the AC of eyes of mice with EAU failed to induce ACAID. CONCLUSIONS: The intraocular inflammation of EIU and EAU disrupted important parameters of immune privilege, ranging from breakdown of the blood- ocular barrier, to loss of an immunosuppressive microenvironment, to abrogation of ACAID. Because AqH from inflamed EAU reacquired the ability to suppress T-cell proliferation, the authors conclude that the capacity to regulate immune expression and inflammation can be a property even of inflamed eyes.  (+info)

Expression of the Mf1 gene in developing mouse hearts: implication in the development of human congenital heart defects. (8/421)

The transcription factor FKHL7 gene has recently been associated with the anterior segment dysgenesis disorder of the eye known as Axenfeld-Rieger anomaly (ARA). A growing body of evidence indicates that mutations in FKHL7 cause not only defects in the anterior segment of the eye but defects in the heart valves and septa as well. In order to evaluate its contribution to normal heart septation and valve formation, expression of the mouse homologue Mf1 in embryonic hearts was analyzed by in situ hybridization. A weak but significant level of Mf1 expression could be detected in the endocardium of mouse embryos as early as day 8.5 post-conception (p.c.). Mf1 expression was undetectable in the hearts of day 9.5 p.c. embryos, but by day 10.5-11 p.c., Mf1 transcripts could be found again in the endocardium of both the atrium and ventricle and a relatively strong signal was observed in the dorsal portion of the septum primum, in what appeared to be the spinal vestibule. At day 13 p.c. when aortic and pulmonary trunks are separated, relatively more Mf1 transcripts were detected in the leaflets of aortic, pulmonary, and venous valves, the ventral portion of the septum primum, as well as in the single layer of cells on the edges of the atrioventricular cushion tissues. Surprisingly, there was no signal detected in the developing interventricular septum. At day 15 p.c., overall Mf1 signals were greatly decreased. However, significant levels of expression could still be observed in the atrial septum, the tricuspid valve, the mitral valve, and in the venous valve but not in the interventricular septum. The temporal and spatial expression patterns of the Mf1 gene in developing mouse hearts suggest that Mf1 may play a critical role in the formation of valves and septa with the exception of the interventricular septum. This is further supported by our studies showing that mutations in the FKHL7 gene were associated with defects in the anterior segment of the eye as well as atrial septal defects or mitral valve defects.

Purpose : Anterior segment optical coherence tomography (AS-OCT) has rapidly increased in popularity as a means of studying the anatomy and biomechanics of the anterior segment. While physiologic factors such as pupil size are known to affect AS-OCT measurements, it is not known if measurement values vary with the time of day. This study examines the diurnal variation of anterior segment structures in young healthy eyes by comparing AS-OCT measurements values obtained in the morning and late afternoon. Methods : Eight subjects ranging from age 28 to 40 with no history of eye conditions or intraocular surgery were selected for this study (6 male, 2 female; mean age 31.2 ± 4.5 years). Anterior segment imaging was performed with a CASIA2 AS-OCT device (Tomey Corporation, Nagoya, Japan) in a fixed lighting environment between the hours of 8 to 9 AM and 4 to 5 PM. Four evenly spaced AS-OCT images per eye were analyzed. Nine parameters including angle opening distance (AOD), angle recess area (ARA), ...
Anterior Eye Segment information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues.
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
In adult p120fl/fl;Wnt1Cre eyes, the corneal stromal cells were disorganized and the corneal epithelium was thinner than in WT eyes. Since corneal stroma originates from NCC and p120ctn is ablated in the corneal stroma of p120fl/fl;Wnt1Cre mice, the observed stromal disorganization might be related directly to p120ctn depletion. However, we have no conclusive evidence for this hypothesis and disorganization of the corneal stroma could also be secondary to incomplete formation of corneal endothelium. In any event, the thinner corneal epithelium in mutant mice reflects an indirect nonautonomous effect because these cells are not derived from NCC. Interestingly, properly formed corneal endothelium has an important role during the development of the anterior segment. 39,40 In the chicken eye, the progressive organization of NCC-derived mesenchymal cells in the anterior chamber, including the induction of N-cadherin expression and a mesenchymal-to-epithelial transition to corneal endothelial cells, ...

Methods: This study involved 58 eyes of 58 open-angle glaucoma cases and 72 eyes of 72 age-matched normal-open-angle control subjects. Iridocorneal angle structures in nasal and temporal regions and anterior chamber depth (ACD) were measured using AS-OCT. Axial length and refractive error were measured by use of an ocular biometer and auto refractor keratometer. Angle opening distance (AOD), angle recess area (ARA), and trabecular-iris space area (TISA), measured at 500 µm (TISA500) and 750 µm (TISA750)
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.

To assess the relationship between intraocular pressure (IOP) and anterior chamber angle (ACA) configuration as assessed by gonioscopy and anterior segment optical coherence tomography (AS-OCT). A total of 2045 subjects aged 50 years and older,
The Pentacam is a high-resolution rotating Scheimpflug camera and slit illumination system that enables precise and reliable imaging and analysis of the anterior segment structures of the eye such as the cornea, iris and lens. Images only take 2 seconds to acquire, and do not require any contact with the eye. A 3-dimensional virtual model of the anterior segment is then constructed, and data points are used to calculate corneal topography and elevation on the front and back surface, total corneal power as well as anterior chamber depth and volume amongst other parameters. There are many additional features available on this machine that aid the diagnosis and management of anterior segment diseases such as keratoconus, and assist in pre-operative planning for cataract, corneal and refractive surgery. This is especially helpful for patients who have previously had laser vision correction, and enables detailed analysis of different parameters to optimize post-operative outcomes for patients.. ...

Although OCT angiography (OCT-A) is traditionally for imaging the microvasculature of the posterior segment, its use for imaging anterior segment structures is showing potential.1-5. Unlike current anterior segment assessment methods such as slit lamp and dye-based photography, which offer only a limited view of the vasculature, OCT-A can produce high-resolution cross-sectional images, detect vascularization even in cases of severe corneal opacification and the en face mode can produce frontal plane-oriented C-scans for viewing corneal pathology.1 The iris may also be a particularly strong candidate for en face OCT-A imaging because its flat, thin and easily accessible, though one study found visualization of non-clinically visible vessels depends heavily on iris pigmentation.5. Recently, a study expanded the list of potential anterior segment applications for OCT-A to include the assessment of melanocytic lesions of the conjunctiva and iris.6 The cross-sectional study included 25 patients with ...
Methods. Preparation of adult human retinal pigment epithelium cultures. Human eyes obtained from the National Disease Research Interchange (NDRI, Philadelphia, PA) were processed within 48 h of donor death. The ages and other information regarding donor eyes are shown in Table 1. Four samples from human donor eyes were used; given the expense and availability of human tissue, small sample sizes have been used in the past to generate data on gene expression within human tissue [16-18]. Primary RPE cell cultures were prepared from the posterior poles of the human cadaver eyes as described previously [19]. Upon receipt in the laboratory, eyes were cleaned of extraocular tissue. The anterior segment structures, vitreous, and retina were removed, leaving an eyecup with RPE on the inner surface. For these studies, 500,000 primary ahRPE cells were collected with trypsin from each pair of globes harvested from four individual human donors (age range 48 to 82 years, Table 1). The cells were incubated in ...

Purpose: Although the frequency in which practitioners are fitting scleral contact lenses is increasing, the recommendation for proper tear layer depth (thickness) varies amongst experts. The main goal of this paper is to clinically verify the effect of varying tear layer depths on induced corneal edema during lens wear. Methods: Ten subjects with healthy eyes were fitted with scleral lenses on their right eye. Each of them was fit with two different lenses: one with an apical clearance of 200 μm and another with an apical clearance of 600 μm. They wore the lenses for 8 hours on two different days, with at least a one week wash-out period. Lenses were applied at 8 a.m. on each of the testing days. Pachymetry measurements were taken one day prior to lens wear at 4 p.m., on the day of wear prior to lens application, and after removal of the lenses at 4 p.m. Measurements were collected using both the Pentacam® HR Corneal Tomographer, as well as the Visante Anterior Segment Optical Coherence ...

We report a 10-year-old boy with unusually dense, bilateral central posterior capsule pigmentation associated with the characteristic clinical features of pigment dispersion syndrome, including Krukenbergs spindle and dense trabecular pigmentation in both eyes. There was no history of trauma , laser or intraocular surgeries . The presence of posterior or backward bowing of iris suggested a reverse pupillary block mechanism of pigment dispersion syndrome. Nd Yag laser peripheral iridotomy was performed in both eyes to relieve reverse pupillary block. Anterior segment optical coherence tomography (AS-OCT) showed reversal of iris concavity after laser iridotomy.. ...
Axenfeld-Rieger syndrome (ARS) is associated with mutations in the PITX2 gene that encodes a homeobox transcription factor. Several intronic PITX2 mutations have been reported in Axenfeld-Rieger patients but their effects on gene expression have not been tested. We present two new families with recurrent PITX2 intronic mutations and use PITX2c minigenes and transfected cells to address the hypothesis that intronic mutations effect RNA splicing. Three PITX2 mutations have been analyzed: a G|T mutation within the AG 3 splice site (ss) junction associated with exon 4 (IVS4-1G|T), a G|C mutation at position +5 of the 5 (ss) of exon 4 (IVS4+5G|C), and a previously reported A|G substitution at position -11 of 3ss of exon 5 (IVS5-11A|G). Mutation IVS4+5G|C showed 71% retention of the intron between exons 4 and 5, and poorly expressed protein. Wild-type protein levels were proportionally expressed from correctly spliced mRNA. The G|T mutation within the exon 4 AG 3ss junction shifted splicing exclusively to

Age-related macular degeneration (AMD) is a major cause of vision loss in the elderly. To better study the pathobiology of AMD, postmortem eyes offer an excellent opportunity to correlate optical coherence tomography (OCT) imaging characteristics with histopathology. However, postmortem eyes from autopsy present challenges to standard OCT imaging including opaque anterior segment structures and standard of care autopsy processing resulting in oblique views to the macula. To overcome these challenges, we report a custom periscope attached by a standard mount to an OCT sample arm and demonstrate high quality macular OCT acquisitions in autopsy-processed eyes.. © 2017 Optical Society of America.

PURPOSE: We sought to investigate anatomic mechanisms of angle narrowing by assessing ocular biometric determinants of anterior chamber angle width. DESIGN: Population-based cross-sectional study. METHODS: Subjects ≥50 years of age from the Chinese American Eye Study underwent a comprehensive ocular examination, including anterior segment optical coherence tomography imaging and ultrasound A-scan. Independent variables, including anterior chamber depth (ACD), lens vault (LV), iris curvature (IC), anterior chamber width, lens thickness, vitreous cavity depth, and axial length, and dependent variables, including angle opening distance, were measured in 1 randomly selected eye per subject. Univariable and multivariable regression models with standardized regression coefficients (SRCs) and semipartial correlation coefficients squares (SPCC) were used to assess relative and unique contributions by independent variables to angle width. RESULTS: Two thousand two hundred twenty-five subjects (1433 ...
Hundred twenty-eight eyes of 73 patients with moderate to high myopia and/or astigmatism (spherical equivalent < -10.0 dpt, astigmatism < 5.0 dpt) were measured with non-contact tonometry and ultra-high-speed camera (Corvis® ST, Oculus) before and after surgical treatment. Fourty-eight eyes were treated with the femtosecondlaser for flap generation (VisuMax®, Carl Zeiss Meditec) and ablated with an eximer laser (Mel 80 ™, Carl Zeiss Meditec). Eighty eyes were treated with an all-femto-procedure by generating an intrastromal lenticule and then extracting the lenticule through a small incision (ReLEx-smile: small incision lenticle extraction). All patients were operated by the same surgeon (RW). Preoperatively and one month to three months postoperatively following data were analyzed: UDVA, CDVA, refraction, biomicroscopy of anterior eye segment, IOP with non-contact tonometry and Goldmann tonometry and deformability of the cornea using the Corvis® ST. Data were analyzed using SPSS version ...
The aim of this study was preparation and evaluation of ciprofloxacin-containing minitablets for ocular use, in an attempt to obtain prolonged and controlled drug release to the anterior eye segment. Following initial studies on ciprofloxacin powder, it was formulated into ocular minitablets. For this purpose, ciprofloxacin along with various amounts of different sustained release cellulose derivatives (HPMC, Na CMC, HEC and EC), Carbopol 974P, solubilizer and lubricant were directly compressed into minitablets, using concave 3 mm diameter punches. All the prepared formulations were evaluated in terms of physicochemical tests, including uniformity of weight, friability, crushing strength, water uptake and in-vitro drug release studies. It was found that the type and amount of cellulose derivatives used, can influence the rate of drug release. The finally selected formulation (B3) contained ethyl cellulose, Carbopol 974P, mannitol, sodium stearyl fumarate and ciprofloxacin, which showed more than 80%
A total of 15 eyes were scanned with the Visante Omni. A lid speculum was used to keep the rabbits eye open during the measurements to ensure that the eyelids did not block the 10-mm diameter mapping area. The cornea was kept wet regularly with balanced salt solution to prevent the ocular surface from drying. First, the cornea was scanned with ATLAS corneal topographer, incorporated with the Visante Omni, where 8000 data points of the anterior corneal surface were recorded. The anterior corneal topography data were then transferred to the Visante OCT station via a network link. The rabbit was then moved to the Visante OCT station to scan for global pachymetry. Pachymetry alignment with anterior corneal surface data, obtained from the ATLAS corneal topographer, required the observer to locate the center of the pupil, which was achieved when the vertex produced a vertical white line behind the center of the cornea. Thereafter, the Visante OCT system would lock onto the vertex and track it so that ...
Purpose: To evaluate the anatomic stability of an implanted Boston Type I Keratoprosthesis (KPro)-donor cornea interface, and assess the presence or absence of a potential space (gap) between the KPro front plate and donor cornea using anterior segment optical coherence tomography (AS- OCT). The presence of a gap would raise concerns of a possible pathway for the exchange of fluid between the ocular surface and the anterior chamber.. Methods: Fourteen eyes implanted with a Boston Type I KPro were studied by the non-contact technique of AS-OCT (AC Cornea OCT prototype, OTI, Canada). All the KPro devices had been implanted at least 4 weeks prior to the study (range: 1 to 22 months). Seven eyes had aphakic Kpros and the other 7 had pseudophakic implants. Anesthetized eyes were imaged before and during pressure application using sterile cotton tip applicators. Pressure was applied for 10 seconds just outside the temporal limbal area. Images were analyzed for any possible changes in the KPro-donor ...
The phenotype seen in this 14q32 linked family comprises varying degrees of microphthalmia in association with severe anterior segment abnormalities. There is, however, no evidence of coloboma or of anomalies of the lens, vitreous, or retina. While it is possible that altered scleral rigidity in these abnormal eyes may have rendered the Schiotz tonometer readings somewhat inaccurate it seems certain that raised intraocular pressure forms part of this microphthalmia phenotype. Since highly elevated intraocular pressures may be observed even at the age of 1 year it is possible that this may contribute significantly to the progressive corneal changes observed including staphyloma formation. The marked corneal opacity observed at this age (Fig 2A) may be due in part to the raised intraocular pressure, but appears rather too severe to be caused by this alone. Since three eyes belonging to older family members were found to have total sclerocornea it seems likely that corneal changes are a primary ...
A review of the role of ultrasound biomicroscopy in glaucoma associated with rare diseases of the anterior segment Giuseppe Mannino,1 Barmak Abdolrahimzadeh,2 Silvia Calafiore,1 Gianmario Anselmi,1 Cristina Mannino,1 Alessandro Lambiase3 1Ophthalmology Unit, Saint Andrea Hospital, Department of Neurosciences, Mental Health and Sense Organs, University of Rome “Sapienza”, Rome, Italy; 2Polimed Beltramelli Medical Centre, Rome, Italy; 3Department of Sense Organs, Ophthalmology Unit, University of Rome “Sapienza”, Rome, Italy Abstract: Ultrasound biomicroscopy is a non-invasive imaging technique, which allows high-resolution evaluation of the anatomical features of the anterior segment of the eye regardless of optical media transparency. This technique provides diagnostically significant information in vivo for the cornea, anterior chamber, chamber angle, iris, posterior chamber, zonules, ciliary body, and lens, and is of great value in assessment of the mechanisms of glaucoma

Background: Isolated minor T-wave abnormalities not accompanied by ST segment abnormalities or findings of left ventricular (LV) hypertrophy are frequently observed in the general population and their prognostic value is less clear as ST segment abnormalities. However, it may depend on presence or absence of hypertension.. Methods: Associations of cardiovascular mortality with the isolated minor T-wave abnormalities were studied in citizens who received ECG in the health examination of Moriguchi city, Osaka, Japan in 1997, stratified by presence or absence of hypertension. ECGs were read by 3 cardiologists with the judgment of minor or major abnormalities blinded to any clinical information including blood pressure except for age and sex. Subjects with any major abnormalities on the ECG, history of cardiovascular disease, left bundle branch block, intraventricular conduction delay, or non-sinus rhythm were excluded.. Results: There were 13,297 subjects and 4,301 subjects had hypertension. Mean ...

PURPOSE: Mutations in murine and human versions of an ancestrally related gene usually result in similar phenotypes. However, interspecies differences exist, and in the case of two forkhead transcription factor genes (FOXC1 and FOXC2), these differences include corneal or anterior segment phenotypes, respectively. This study was undertaken to determine whether such discrepancies provide an opportunity for identifying novel human-murine ocular phenotypes. METHODS: Four pedigrees with early-onset glaucoma phenotypes secondary to segmental chromosomal duplications or deletions encompassing FOXC1 and 18 individuals from 9 FOXC2 mutation pedigrees underwent detailed ocular phenotyping. Subsequently, mice with mutations in Foxc1 or a related forkhead gene, Foxe3, were assessed for features of the human phenotypes. RESULTS: A significant increase in central corneal thickness was present in affected individuals from the segmental duplication pedigrees compared with their unaffected relatives (mean
3Yrd. Doç. Dr., Afyon Kocatepe Üniversitesi Tıp Fakültesi, Göz Hastalıkları, Afyon - Türkiye To present a rare case of vitreous cyst in our society. A 9-year-old male presented with blurred vision in the right eye with varying position. Anterior segment examination was normal. Cystic formation was observed posterior to the lens. The cyst swam in the vitreous and displaced position. B scan USG in left eye showed cystic, well-defi ned, rounded, non-fi xated, and 4 mm diameter formation. When assessed with anterior segment OCT, the cyst confi rmed a thin, well-defi ned cyst wall with a hyporefl ective lumen. There were small hyperrefl ective dots in the cyst. Vitreous cysts were considered. Vitreous cysts represent an uncommon condition and are usually incidental clinical fi ndings. This condition has been seen to occur in younger patients of 6-8 years old.across the whole range of adults, although it is seen mostly from 10 to 20 years of age. The numbers and positioning of such cysts ...

Assembly of the Boston KPro with the threaded system has never been technically difficult. On occasion, however, surgeons have complained that they have mis-threaded the back plate and it has gotten stuck - without adverse clinical consequences, however. Also, recent examinations with high-definition OCT has revealed that not all threaded back plates have been rotated to completion.(Garcia JP Jr, de la Cruz J, Rosen RB, Buxton DF. Imaging implanted keratoprostheses with anterior segment OCT and UBM. 2007 ARVO poster #3868.) The consequence has been a space that is too wide for the corneal graft which has not swelled sufficiently to completely occupy the space. This has resulted in the front plate not lying flat on the graft surface but extruding forwards. Such configuration can result in exposure and tissue melt if the contact lens should become lost. Such assembly difficulties should be avoided with the new threadless design. As long as the locking ring has snapped into the groove, as has been ...

The paradox exists, not as a whim or grimace on the part of Nature but for a definite and vital end. In default the animal would be unable to obey the first law of Nature - self preservation - for it is soft-bodied and its dwelling has the serious defect of being open at both ends. In such plight lacking special organs it would be at cruel advantage in the struggle for existence. The posterior segment of the body is therefore developed into an operculum-like organ, smooth and of horny texture, which closes the narrow end of the tube. The other extremity is more elaborately guarded, the anterior segment being fringed with a frontal membrane, while the second segment forms a disc, the minute mouth orifice with the true tentacles and gills being debased to the third segment.. Confronted by danger, the animal closes its front door by retracting until the disc presses immovably against the circumference of the tube, the retraction being so sudden that a frail spurt betrays the whereabouts of an ...
