Aqueous Humor
Wit and Humor as Topic
Trabecular Meshwork
Ciliary Body
Fluorophotometry
Iris
Anterior Chamber
The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil. (Cline et al., Dictionary of Visual Science, 4th ed, p109)
Vitreous Body
Uveitis
Blood-Aqueous Barrier
Uveitis, Anterior
Inflammation of the anterior uvea comprising the iris, angle structures, and the ciliary body. Manifestations of this disorder include ciliary injection, exudation into the anterior chamber, iris changes, and adhesions between the iris and lens (posterior synechiae). Intraocular pressure may be increased or reduced.
Anterior Eye Segment
Administration, Topical
The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
Cataract
Rabbits
Timolol
Sclera
The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the canal of Schlemm. (From Cline et al., Dictionary of Visual Science, 4th ed)
Glaucoma
An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)
Exfoliation Syndrome
The deposition of flaky, translucent fibrillar material most conspicuous on the anterior lens capsule and pupillary margin but also in both surfaces of the iris, the zonules, trabecular meshwork, ciliary body, corneal endothelium, and orbital blood vessels. It sometimes forms a membrane on the anterior iris surface. Exfoliation refers to the shedding of pigment by the iris. (Newell, Ophthalmology, 7th ed, p380)
Uvea
Eye
Toxoplasmosis, Ocular
Infection caused by the protozoan parasite TOXOPLASMA in which there is extensive connective tissue proliferation, the retina surrounding the lesions remains normal, and the ocular media remain clear. Chorioretinitis may be associated with all forms of toxoplasmosis, but is usually a late sequel of congenital toxoplasmosis. The severe ocular lesions in infants may lead to blindness.
Glaucoma, Open-Angle
Cornea
The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)

Iridocyclitis
Transforming Growth Factor beta2
A TGF-beta subtype that was originally identified as a GLIOBLASTOMA-derived factor which inhibits the antigen-dependent growth of both helper and CYTOTOXIC T LYMPHOCYTES. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta2 and TGF-beta2 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.

Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Eye Infections, Viral
Infections of the eye caused by minute intracellular agents. These infections may lead to severe inflammation in various parts of the eye - conjunctiva, iris, eyelids, etc. Several viruses have been identified as the causative agents. Among these are Herpesvirus, Adenovirus, Poxvirus, and Myxovirus.

Estimation of corneal endothelial pump function in long-term contact lens wearers. (1/1321)
PURPOSE: To study the effects of long-term contact lens wear on morphologic and physiologic properties of corneal endothelial cells. METHODS: The endothelial permeability to fluorescein and the rate of corneal deswelling from hypoxia-induced edema were measured in 20 long-term (mean, 17+/-9 years; range, 5-33 years) contact lens wearers and 20 age-matched control subjects. From these data, the relative endothelial pump rate in each subject was estimated, based on the pump-leak hypothesis of corneal hydration control. Corneal autofluorescence and the aqueous humor flow rate were determined by fluorescein fluorophotometry. Images of corneal endothelial cells were recorded by using specular microscopy, and morphologic indices (cell density, coefficient of variation of cell area, percentage of hexagonal cells, and skewness) were determined. RESULTS: No statistically significant differences were found between the contact lens and control groups in endothelial permeability, corneal deswelling, relative endothelial pump rate ([mean +/- SD] 1.07+/-0.33 relative pump units versus 1.01+/-0.25 relative pump units; contact lens versus control; P = 0.57), and endothelial cell density. Contact lens wearers had a significantly higher aqueous humor flow rate (3.57+/-1.03 microl/min versus 2.77+/-0.51 microl/min; P = 0.005), coefficient of variation of cell area (0.35+/-0.09 versus 0.28+/-0.04; P = 0.006), and corneal autofluorescence (3.1+/-0.6 ng/ml versus 2.3+/-0.3 ng/ml fluorescein equivalents; P < 0.001) than did non-contact lens wearers. CONCLUSIONS: Despite the known effects of long-term contact lens wear on corneal endothelial morphometry, no effect on endothelial function was found. (+info)Latrunculin-A increases outflow facility in the monkey. (2/1321)
PURPOSE: To determine the effect of Latrunculin (LAT)-A, a macrolide that binds to G-actin, which leads to the disassembly of actin filaments, on shape, junctions, and the cytoskeleton of cultured bovine aortic endothelial cells (BAECs) and on outflow facility in living monkeys. METHODS: Latrunculin-A dose-time-response relationships in BAECs were determined by immunofluorescence and phase contrast light microscopy, facility by two-level constant pressure anterior chamber perfusion. RESULTS: In BAECs, LAT-A caused dose- and incubation time- dependent destruction of actin bundles, cell separation, and cell loss. Cell-cell adhesions were more sensitive than focal contacts. Recovery was also dose- and time-dependent. In monkeys, exchange intracameral infusion and topical application of LAT-A induced dose- and time-dependent several-fold facility increases. The facility increase was completely reversed within several hours after drug removal. However, for at least 24 hours after a single topical LAT-A dose, perfusion with drug-free solution caused an accelerated increase in facility beyond that attributed to normal resistance washout. CONCLUSIONS: Pharmacological disorganization of the actin cytoskeleton in the trabecular meshwork by specific actin inhibitors like LAT-A may be a useful antiglaucoma strategy. (+info)Effect of staurosporine on outflow facility in monkeys. (3/1321)
PURPOSE: To determine the effect of the serine-threonine kinase inhibitor staurosporine on outflow facility in living monkeys. METHODS: Total outflow facility was determined by two-level constant pressure perfusion of the anterior chamber bilaterally before and after intracameral infusion of staurosporine or vehicle in opposite eyes. RESULTS: Intracameral staurosporine dose-dependently doubled outflow facility, with 0.1 microM, 1 microM, and 10 microM being subthreshold, effective, and maximal doses, respectively. At 50 microM, intracameral staurosporine was less effective than 10 microM on facility and induced corneal toxicity. CONCLUSIONS: The broad-spectrum protein kinase inhibitor staurosporine increases outflow facility in living monkeys, perhaps by affecting the trabecular meshwork cytoskeleton. (+info)Cytomegalovirus (CMV) retinitis activity is accurately reflected by the presence and level of CMV DNA in aqueous humor and vitreous. (4/1321)
To evaluate the potential of ocular and systemic specimens to provide markers of active cytomegalovirus (CMV) retinitis, we examined the relationship between virologic and clinical aspects of CMV infections in AIDS patients with CMV retinitis. CMV polymerase chain reaction (PCR) analysis of 74 aqueous humor and vitreous specimens indicated that ocular specimens can provide accurate markers to differentiate active and inactive CMV retinitis (aqueous or vitreous PCR, P<.001). Moreover, these markers were superior to extraocular measures, including plasma PCR (P=.08) and blood and urine CMV cultures (P=.05). A direct correlation was identified between the quantity of CMV DNA in aqueous humor or vitreous specimens and the corresponding surface area of active CMV retinitis (r2=.69 and.44, respectively). Thus, qualitative and quantitative PCR-based analyses of aqueous humor can provide valuable markers of CMV retinitis activity. Such assays could provide rapid and reliable tools to assist in management of patients with CMV retinitis in whom the view of the retina is obscured. (+info)High frequency of persistent hyperplastic primary vitreous and cataracts in p53-deficient mice. (5/1321)
In order to investigate whether the p53 gene product plays a role in normal eye development, age matched p53-deficient mice and wild-type controls were sacrificed from day 2 to day 21 after birth. Eyes were paraffin-embedded and sectioned. Serial sections were taken at the level of the tunica vasculosa lentis and the hyaloid artery. The terminal dUTP nick-end labelling technique (TUNEL) was used to detect the number of cells displaying DNA fragmentation within these structures. Eyes were also prepared for scanning electron microscopy and resin embedded for semi-thin sections. Adult wild-type mice and p53-deficient mice were examined ophthalmoscopically in vivo. Ophthalmoscopical examination of mice completely deficient in p53 revealed them to be normal except for the persistence of the hyaloid vasculature, a structure that normally regresses during eye development. In adult animals there was also a high frequency of cataracts. Using morphological assessment and TUNEL we could show that in normal mice, regression of the primary vitreous, which includes the hyaloid artery, the vasa hyaloidea propria as well as the tunica vasculosa lentis, occurs via apoptotic cell death within 5 - 6 weeks after birth. The number of TUNEL-positive cells within these structures was significantly reduced in the p53-deficient mice in which parts of the hyaloid vasculature persisted and developed into a fibro-vascular retrolental plaque analogous to persistent hyperplastic primary vitreous (PHPV) described in humans. As in humans, PHPV in mice resulted in the development of cataracts. We have identified a role for p53-dependent apoptosis in the regression of the hyaloid vasculature and tunica vasculosa lentis. Our results provide further evidence for the importance of p53 in normal development and provide the first detailed evidence of its role in postnatal development in remodelling the developing eye. (+info)Electrical parameters of the isolated cornea of the dogfish, Squalus acanthias. (6/1321)
The electrical potential difference and electrical resistance of the nonswelling cornea of the dogfish, Squalus acanthias, were examined. It was found that routine procedures used in the procurement of fish invariably produce damage to the corneal epithelium which affects electrical measurements and possibly composition of the aqueous humor. We found no electrical evidence of ionic pumps in the corneal epithelium of this elasmobranch. The electrical resistance of corneas with apparently well-preserved epithelium was 300omega-cm.2 (compared to 30omega-cm.2 in corneas with damaged epithelium). (+info)Enthacrynic and acid effects on inner wall pores in living monkeys. (7/1321)
PURPOSE: The influence of the inner wall of Schlemm's canal on aqueous outflow facility remains poorly understood. We examined the relationship between inner wall pore characteristics and outflow facility in living primate eyes in which facility had been pharmacologically increased by ethacrynic acid (ECA) infusion and in contralateral control eyes. METHODS: Outflow facility (two-level constant pressure perfusion) was measured in eight pairs of living monkey eyes before and after administration of a bolus dose of either 0.125 mM ECA or vehicle. After exsanguination, eyes were fixed in situ under constant-pressure conditions (mean fixation pressure approximately 19 mm Hg). The density and diameter of inner wall pores and the number and area of platelet aggregates on the inner wall of Schlemm's canal were measured by scanning electron microscopy. RESULTS: In ECA-treated eyes, outflow facility increased 63% (P < 0.0001), intracellular pore density decreased 46% (P = 0.0094), intracellular pore size increased 27% (P = 0.049), platelet aggregate density increased 158% (P < 0.0001), and area covered by platelets increased 210% (P = 0.012) relative to contralateral controls. Although the average density and size of intercellular pores were essentially unaffected by ECA, an increased density of large (> or = 1.90 microm) intercellular pores was seen in ECA-treated eyes. The density of intracellular pores increased with the duration of fixative perfusion. Other than a weak negative correlation between outflow facility and intracellular pore density in ECA-treated eyes (P = 0.052), facility was not correlated with inner wall pore features. CONCLUSIONS: Our data are most consistent with a scenario in which ECA promotes formation of large intercellular pores in the inner wall of Schlemm's canal, which are then masked by platelet aggregates. Masking of intercellular pores, combined with fixation-induced alteration of inner wall pore density, greatly complicates attempts to relate facility to inner wall structure and suggests that in vivo pore density is smaller than in fixed tissue. Additionally, facility-influencing effects of ECA on the juxtacanalicular tissue cannot be excluded. (+info)Effect of aqueous humor on apoptosis of inflammatory cell types. (8/1321)
PURPOSE: To determine whether aqueous humor promotes cell death in cells involved in inflammatory responses. METHODS: Multiple immune cell types, most characteristically involved in inflammatory responses, were incubated for 24, 48, and 72 hours in the presence or absence of 50% aqueous humor. Promotion of cell death was assayed by staining for an early indicator of apoptosis. The percentage of cells undergoing apoptosis was measured by flow cytometry. To identify partially the apoptosis inducing factor, aqueous humor was pretreated with proteinase K to degrade protein. In other experiments, aqueous humor was fractionated by centrifugation on filters capable of separating molecules above and below 10 kDa or 30 kDa kilodaltons in size. RESULTS: Rabbit aqueous humor promoted apoptosis in a wide variety of immune cells, including lymphokine-activated natural killer cells, resting T cells, an activated T-cell line, RAW 264.7 and J774A0.1 monocyte-macrophage cell lines, and neutrophils. As previously shown, aqueous humor did not promote apoptosis of murine corneal endothelial cells. Apoptosis was also not induced in human corneal endothelium, mouse corneal epithelium, or iris/ciliary body cell lines. Instead, aqueous humor partially protected these ocular tissues from starvation-induced cell death. Pretreatment with proteinase K inhibited the apoptosis-inducing activity. Moreover, the apoptosis-inducing activity segregated with the aqueous humor fraction containing molecules less than than 10 kDa in size. CONCLUSIONS: These data show that aqueous humor contains a factor or factors that promote death of cells that participate in inflammatory processes. By contrast, ocular tissues, such as the corneal endothelium and iris/ciliary body, are impervious to aqueous humor-induced cell death. The aqueous humor- borne factor(s) may contribute to the immune privilege of the anterior chamber by purging potential inflammatory cells. (+info)

- The detection of virus in aqueous humor by PCR is effective and safe for diagnosis of PSS, and helpful for targeted treatment on virus-positive patients. (researchsquare.com)
- We performed high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) Isotopic Ratio Outlier Analysis of aqueous humor samples from patients from patients with pseudoefoliation syndrome (PEX). (omicsdi.org)
- Proteomic analysis of Exosomes derived from the Aqueous Humor of Myopia Patients. (omicsdi.org)
- The present study aimed to investigate the aqueous humor cytokine expression profile in nAMD patients before and after ranibizumab treatments in comparison to cataract patients. (biomedcentral.com)
- Studying aqueous cytokines in nAMD patients is feasible and necessary to understand the pathogenesis of nAMD, and could provide ideas to develop new antibody drugs. (biomedcentral.com)
- Spirochetes have now been found in aqueous humor, cerebrospinal fluid, liver, and lymph nodes in several patients with late seronegative syphilis. (lymenet.org)
Suppression2
- Medical treatment consists of cycloplegia and aqueous suppression, as well as hyperosmotic agents (eg, oral glycerin or intravenous mannitol). (aao.org)
- In the cat model, haloperidol increased aqueous humor (AH) outflow initially, followed by a long-lasting suppression of AH formation. (jamanetwork.com)
Injections1
- Aqueous humor samples were collected before the first (baseline), second (1 month later), and third (2 months later) injections. (biomedcentral.com)
Paracentesis1
- Marked IOP elevation in the early postoperative period may be temporarily managed by applying gentle pressure on the posterior lip of a preexisting paracentesis incision to release a small amount of aqueous humor. (aao.org)
Reduction1
- Topical and/or systemic pressure-lowering agents should also be administered, as IOP reduction after aqueous release is short-lived, with the IOP likely to rise again within 1-2 hours of decompression. (aao.org)
Fills1
- The fluid that fills this area is called the aqueous humor. (encoredocs.com)
