The study compared 272 eyes from 137 PA patients and 352 eyes from 177 control subjects selected randomly from 1173 participants of a public glaucoma screening. The presence of glaucomatous optic disc appearance (rim thinning and cup enlargement) and retinal nerve fiber layer defects (RNFLDs) was determined independently from fundus photographs. The results were compared between the PA and control groups. Although the prevalence of glaucomatous optic disc appearance did not differ between the two groups, RNFLDs were more frequent in PA patients than in the control group. Moreover, RNFLDs with their central ends located around retinal vessels were characteristic of PA patients.
