Understanding visual field (VF) and retinal nerve fiber layer (RNFL) damage observed in myopic eyes is important. Therefore, we evaluated optic disc margin anatomy using spectral-domain (SD) optical coherence tomography (OCT). We enrolled 40 healthy myopic patients and 64 myopic patients with ...
There is no evidence indicating a correlation between the size and localization of AVM and the pattern of visual field defect.1,2 However, the closer localization to the posterior cerebral region can cause more congruent visual field defect in general.1 In this article, we present a case with...
and the pattern-reversal VEP reflect activity arising from the central visual field [59]. The pattern ERG provides an objective measure of central retinal function [60] but is dependent on the stimulus field size [39]. Therefore, with a larger stimulus field size also, non-macular regions...
Visual field defects are a conglomerate of patterns of visual impairment derived from diseases affecting the optic nerve as it extends from the globe to the visual cortex. The anatomy of this region is complex, largely existing in pairs and consisting of the globes, optic nerve/sheath complexes,...

Left, Humphrey visual field plots of both eyes. All patients had impairment of visual fields, secondary to papilledema. With case 2, the visual field of the left eye couldn’t be tested due to the poor vison. Right, FVEP plots for cases 1 and 2, showing only mild abnormalities (normal ...
