Abstract
Although X-linked retinoschisis is a common retinal degeneration condition, the presence of a large retinal cyst obscuring the visual axis in an infant is a rare presentation. Herein, we describe such a case of a child who presented to us with the diagnosis of retinal detachment in both the eyes. However, following multimodal imaging and electrophysiology, the child was found to have bilateral juvenile retinoschisis with a large retinoschisis cyst involving the visual axis seen intraoperatively in the left eye. A limbal approach followed by lensectomy was used to excise the inner retinal layer of the cyst. The intracystic fluid was then drained and the stretched retinal vessels were endocauterized and severed without causing any iatrogenic outer retinal breaks and retinal detachment. The correct diagnosis and meticulous preoperative planning of the surgical procedure helped us manage this challenging case with a favorable anatomical and functional outcome.
