Peripapillary Retinoschisis in Non-Glaucomatous Eyes

ABSTRACT

PURPOSE: To investigate the characteristics of non-glaucomatous eyes with peripapillary retinoschisis. METHODS: Six non-glaucomatous eyes with peripapillary retinoschisis were enrolled. Age, sex, refractive error, intraocular pressure, location and changes of peripapillary retinoschisis, and the presence of accompanied abnormalities were assessed. To determine possible abnormalities of the optic nerve head and macula, fundus photographs and cross-sectional images of the optic nerve head and macula obtained by optical coherence tomography were inspected. RESULTS: Three males and 3 females were enrolled. Age of the subjects ranged from 11 to 59 years (median, 45 years). Refractive error ranged from -6.25 to +1.00 diopter (median, -0.50 diopter). Peripapillary retinoschisis was located in the superior quadrant in four eyes, in the nasal quadrant in one eye, and in the inferior quadrant in one eye, respectively. No additional abnormalities were found in fundus photographs or in the cross-sectional images of the optic nerve head and macula that were obtained by optical coherence tomography. Longitudinal follow-up was available for two eyes and spontaneous resolution of peripapillary retinoschisis was observed in these eyes 6 and 9 months later, respectively. CONCLUSIONS: Peripapillary retinoschisis was observed in non-glaucomatous eyes. This finding was observed in subjects of various ranges of age and refractive error, and in both sexes, without any other accompanying abnormalities.
