PURPOSE Normative data on the systematic changes in visual sensitivity as a function of retinal eccentricity have provided the basis for efficient threshold strategies and data analysis routines for static perimetry. The standard methods of assessing visual field changes in patients also could be used for monkeys with experimentally induced ocular disorders if the normal visual fields of monkey...

PURPOSE To investigate the relationship between ganglion cell losses and visual field defects caused by glaucoma. METHODS Behavioral perimetry and histology data were obtained from 10 rhesus monkeys with unilateral experimental glaucoma that was induced by argon laser treatments to their trabecular meshwork. After significant visual field defects had developed, the retinas were collected for ...

Background: Elevated intraocular pressure (IOP) is one of the most important factors for diagnosis and monitoring glaucoma. IOP currently only modifiable risk factor glaucoma, cornea transparent tissue covering front eye. It a powerful refracting surface, providing 2/3 eye's focusing power. The adult about 1/2 millimeter thick comprised 6 layers: epithelium, Bowman's membrane, stroma, Dua's lay...

Post-chiasmatic damage to the visual system leads homonymous field defects (HVDs), which can severely interfere with daily life activities. Visual Restitution Training (VRT) recover parts of affected in patients chronic HVDs, but training outcome is variable. An untested hypothesis suggests that potential may be largest regions ‘neural reserve’, where cortical responses stimulation do not lead ...
