Acute Vitreous and Intraretinal Hemorrhage with Multifocal Subretinal Fluid in Juvenile X-Linked Retinoschisis.

Purpose: To report a rare case of spontaneous vitreous and intraretinal hemorrhage in a patient with juvenile X-linked retinoschisis which was managed conservatively.

Methods: Single patient case report.

Introduction: Juvenile X-linked retinoschisis (JXLR) most often occurs as a result of a genetic defect in the retinoschisin (RS1) gene, causing a separation between the ganglion cell layer and the nerve fiber layer. Spontaneous vitreous hemorrhage has been reported as an uncommon secondary consequence of JXLR. We present a case of spontaneous vitreous and diffuse macular intraretinal hemorrhages in a patient with JXLR which resolved with medical management alone.

Results: A 23-year-old man with a history of juvenile X-linked retinoschisis presented to the ophthalmic emergency room complaining of acute onset of floaters in his right eye. On examination, the patient was found to have a new vitreous hemorrhage with diffuse intraretinal hemorrhages in his right eye, without new retinal tears or detachment. SD-OCT demonstrated multifocal pockets of subretinal fluid. The genetic testing panel revealed a hemizygous mutation in the RS-1 gene. He was managed conservatively on oral acetazolamide, with the resolution of the subretinal fluid and with both visual and symptomatic improvement.

Conclusions: Spontaneous vitreous hemorrhage may rarely occur in patients with JXLR, even in the absence of acute retinal tear or detachment. This case demonstrates an atypical presentation of vitreous hemorrhage with diffuse intraretinal hemorrhage and new multifocal areas of subretinal fluid which improved without surgical intervention. Good outcomes may be achieved in these patients with conservative management alone, even in atypical presentations.
