Comparing retinal nerve fiber layer thickness by OCT with P-ERG in the diagnosis and monitor of open-angle glaucoma

Objective To compare the diagnostic and monitoring ability of retinal nerve fiber layer(RNFL)thickness measured by optical coherence tomography(OCT)and pattern electroretinogram(PERG)in primary open-angle glaucoma(POAG).Methods In a cross-sectional clinical study,26 patients(50 eyes)with POAG were measured with OCT and PERG.The abnormal rates of OCT and PERG were compared by paired χ 2 test,and the correlation between RNFL thickness and PERG was...
