A 12-year-old boy presented with defective vision OU (OD 20/200, OS 20/40). Fundus examination OD revealed foveoschisis with multiple outer retinal holes with retinal detachment (RD) with subretinal gliotic bands [Figure 1]. OS had foveoschisis with vitreous veils. Optical coherence tomography confirmed foveoschisis. Full-field electroretinogram showed reduced b-wave with preserved a wave. Diagnosis of juvenile X-linked retinoschisis (JXLR) with RD was made. | Figure 1: Color fundus montage OD showing foveoschisis (black arrowhead), subretinal gliosis (white arrowhead) veil-like inner layer (red arrow), and multiple outer retinal holes (white arrow) with retinal detachment.

JXLR is caused due to the mutations in the RS1 gene on Xp22.1 coding for retinoschisin.[1] The split occurs in the nerve fiber layer. Genetic trials with RS1 knockout mice have shown better b-wave function.[2]
