Aqueous Humor Dynamics in Exfoliation Syndrome

Aqueous humor dynamics in pigment dispersion syndrome.

OBJECTIVE To assess aqueous humor dynamics in pigment dispersion syndrome (PDS). METHODS Four groups of age-matched participants included 2 experimental groups with PDS (PDS with ocular hypertension [PDS-OHT], 17 eyes; PDS without ocular hypertension [PDS-ONT], 18 eyes) and 2 control groups without PDS (OHT, 18 eyes; ONT, 18 eyes). Assessments included intraocular pressure measured by pneumat...

Aqueous humor dynamics in mice.

PURPOSE To assess aqueous humor dynamics in mouse eyes. METHODS Aqueous humor dynamics of NIH Swiss White mouse were assessed with an injection and aspiration system, using fine glass microneedles. Intraocular pressure (IOP) was measured by a microneedle connected to a pressure transducer. Episcleral venous pressure (EVP) was measured by gradually lowering intracameral pressure until blood re...

Aqueous Humor Dynamics: A Review

Glaucoma is a family of optic neuropathies which cause irreversible but potentially preventable vision loss. Vision loss in most forms of glaucoma is related to elevated IOP with subsequent injury to the optic nerve. Secretion of aqueous humor and regulation of its outflow are physiologically important processes for maintaining IOP in the normal range. Thus, understanding the complex mechanisms...

Aqueous Humor: Physiology and Dynamics

Aqueous humor dynamics in glaucomato-cyclitic crisis.

The transfer coefficients of fluorescein in the anterior chamber by flow, kfa, and by diffusion, kdpa, can be calculated for an individual human eye, through an analysis of fluorescein concentrations in the anterior chamber, pupillary aqueous, and serum ultrafiltrates following intravenous injection. Using this technique, aqueous humor dynamics was studied in eight patients with glaucomato-cycl...
