Visual field tests help your doctor figure out whether you have blind spots, where they are, and what their shape is. This can tell you a lot about how an eye disease or brain disorder affects you.

Purpose: Vigabatrin (Sabril), a drug that blocks GABA transaminase, has been used in the treatment of epilepsy since 1989. There have been reports of irreversible constriction of the visual field ...

Neuroradiological images and visual perimetries of CB patients. All patients sustained damage of early visual areas or the optic radiations resulting in homonymous visual field defects as shown by ...

OCT of the optic nerve showed a decrease in thickness of the RNFL (Figure 4). Visual field tests were essentially full bilaterally. References: Balcer LJ, et al. J Neuroophthalmol. 1997;17(2):108-121.

In addition, light from the right side of the visual field is projected onto the left side of each eye (Fig 3) and vice versa. The images are ‘gathered’ in the retina and turned into nerve impulses ...

With SSOH, most of your visual field remains intact. But some people with SSOH have impairment of the bottom half of their visual field, since the upper part of the optic nerve can’t transmit ...

However, visual response times and visual acuity did not have a significant correlation (r = 0.273) or contrast sensitivity (r = 0.273). There were some limitations to this study. There was a ...

Event-based visual field progression was more likely in eyes with a faster initial OCTA progression (HR, 1.96; 95% CI, 1.04-3.69), with a similar association found between a faster initial OCT ...

Sekimitsu and colleagues performed archetypal analysis on 263,707 visual fields from 34,331 patients to identify the visual field archetypes associated with genetic risk for POAG and its subtypes ...
