This study used the Matching Pursuit (MP) method, a time–frequency analysis, to identify and characterize oscillatory potentials (OPs) in the primate electroretinogram (ERG). When the slow-sequence mfERG from the macular region of the retina was ma

PURPOSE To determine whether anterior ischemic optic neuropathy and compressive optic neuropathy in humans alter the photopic flash ERG and to investigate the cellular origins of the waves that are affected by pharmacologic agents in primates. METHOD

PURPOSE To determine whether a structure-function model developed for normal age-related losses of retinal ganglion cells also models the retinal ganglion cell losses in glaucomatous optic neuropathy. METHODS The model to relate age-related loss of r

The lamina cribrosa has been postulated from in vitro studies as an early site of damage in glaucoma. Prior in vivo measures of laminar morphology have been confounded by ocular aberrations. In this study the lamina cribrosa was imaged after correcti

Purpose Losses of retinal ganglion cells (RGCs) in glaucoma are the cause of visual field defects and thinning of the retinal nerve fiber layer (RNFL), but methods of correlating these events have not been developed. The present study was conducted t

Primary open-angle glaucoma (POAG) is one of the leading causes of blindness worldwide.1 The death of retinal ganglion cells in POAG is reflected by increased cupping of the optic disc, loss of nerve fiber layer and functional visual field defects.2

Purpose To determine the variations with eccentricity of the primate photopic ERG and to separate contributions by different retinal cells by using intravitreal pharmacologic agents. Methods Slow-sequence multifocal (mf)ERGs were obtained from 19 ane
