Vitreous hemorrhage in X-linked retinoschisis.

PURPOSE

To report a case of preretinal hemorrhage from extraretinal neovascularization related to capillary non-perfused retina within a large schisis in a pediatric patient with X-linked retinoschisis (XLRS).

OBSERVATIONS

A 4-year old male with an mutation and XLRS presented with preretinal and vitreous hemorrhage in the right eye. Retinal imaging, including wide angle fluorescein angiography (FA) and optical coherence tomography (OCT), showed vitreoretinal traction on extraretinal neovascularization and capillary non-perfused retina in the schisis cavity. Laser treatment to the non-perfused retina within the schisis was successful in reducing extraretinal neovascularization.

CONCLUSIONS

Vitreous hemorrhage is a well-known occurrence in XLRS. Imaging using wide angle FA and OCT were helpful to determine the causes of hemorrhage in order to develop a management plan.
