Abstract

PURPOSE: In order to investigate the incidence of relative afferent pupillary defect (RAPD) in normal adolescence and if there is any interocular difference in the case with RAPD. METHODS: Fifty-eight adolescence in 14 to 36 years of age who showed normal findings on measurement of visual acuity, intraocular pressure, slit lamp examination, and funduscopic examination except refractive errors underwent swinging flashlight test and infrared pupillography. The case with RAPD further underwent optical coherence tomography, color vision test, Humphrey visual field test, and Bryngelson test (hole-in-the-card test). RESULTS: One out of 58 cases, in whom more pronounced myopic astigmatism and lower mean deviation on Humphrey visual field test within normal limits were found, showed RAPD in the dominant right eye with swinging flashlight test and infrared pupillography. CONCLUSIONS: The incidence of RAPD in normal adolescence was 1.7%. Myopic astigmatism was higher in the eye with RAPD.
