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 abnor-malities 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 peri-papillary retinoschisis was observed in these eyes 6 and 9 months later, respectively.

Figure 2.
Fundus photographs, optical coherence tomography (OCT) images of eyes with peripapillary retinoschisis (A & B, case 5; C & D, case 6) at the time of retinoschisis formation (A, C) and after the spontaneous decrease in retinoschisis (B, D). Retinoschisis is observed in cross-sectional circumpapillary retinal nerve fiber layer (RNFL) images obtained by OCT (white ar-rows). OCT RNFL thickness maps show transient increase in RNFL thickness (red arrows).
