PURPOSE: To elucidate glaucoma-related fundus abnormalities in patients with primary aldosteronism (PA). METHODS: 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. RESULTS: There were 9 patients (6.6%) with glaucomatous optic disc abnormalities in the PA group and 10 cases (5.6%) identified in the control group (p = 0.92). RNFLDs were detected more frequently in the PA group (55 eyes, 20.2%) than in the control group (26 eyes, 7.4%; p<0.001). The two types of RNFLDs were classified as either having their central ends at the disc margin (D) or away from the disc margin and around the retinal vessels (V). Type D and V RNFLDs were detected in 35 (12.9%) and 26 (9.6%) eyes in the PA group and in 25 (7.1%) and 4 (1.1%) eyes in the control group, respectively. Both types of RNFLDs were more frequent in the PA group than in the control group (Type D and V, p = 0.03, <0.001, respectively). CONCLUSION: 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.
