Rapid Regression of Retinochoroidal Venous Collaterals Following Optic Nerve Sheath Fenestration in Idiopathic Intracranial Hypertension

Abstract

A woman with idiopathic intracranial hypertension (IIH) experienced rapid regression of retinochoroidal venous collaterals (“optociliary shunt vessels”) following optic nerve sheath fenestration. The presence of these vessels is a nonspecific sign of chronic retinal venous compression in patients with optic disc edema including IIH.
