Detection of optic nerve damage in ocular hypertension.
Thirty patients with ocular hypertension were tested for contrast sensitivity loss. Seventeen were not on treatment, and thirteen were receiving some form of pressure reducing therapy. The contrast sensitivity results of 63% of ocular hypertensive eyes were abnormal (greater than 2 SDs from the age matched norm). Thus it appears that contrast sensitivity can detect early visual loss in patients...
متن کاملOptic nerve damage in experimental mouse ocular hypertension.
PURPOSE To evaluate optic nerve damage in mice after laser-induced ocular hypertension. METHODS Ocular hypertension was induced unilaterally in 13 NIH Black Swiss mice by laser photocoagulation of the limbus. Over the following 12 weeks, intraocular pressure (IOP) was measured at regular intervals by the microneedle method. The optic nerves of these mice and of seven normal untreated mice wer...
متن کاملFunctional evaluation of retina and optic nerve in the rat model of chronic ocular hypertension.
PURPOSE To functionally characterize the rat retina and optic nerve after chronic elevation of the intraocular pressure (IOP) using electroretinography (ERG) and computerized pupillometry. METHODS Chronic elevation of the IOP was induced in Brown Norway rats by combined injection of indocyanine green dye (ICG) into the anterior chamber and diode laser treatment, followed by ERG and pupil ligh...
متن کاملLaser scanning tomography of the optic nerve head in ocular hypertension and glaucoma.
BACKGROUND This study evaluated the ability of laser scanning tomography to distinguish between normal and glaucomatous optic nerve heads, and between glaucomatous subjects with and without field loss. METHODS 57 subjects were classified into three diagnostic groups: subjects with elevated intraocular pressure, normal optic nerve heads, and normal visual fields (n = 10); subjects with glaucom...
متن کاملRanking of optic disc variables for detection of glaucomatous optic nerve damage.
PURPOSE To describe optic disc variables assessed by evaluation of clinical optic disc photographs and to compare sensitivity and specificity of these optic disc parameters in identifying patients with ocular hypertension who have nerve fiber layer defects and normal visual fields and patients with visual field defects. METHODS The study included 500 normal subjects, 132 patients with ocular ...
