Rapid regression of retinochoroidal venous collaterals following optic nerve sheath fenestration in idiopathic intracranial hypertension.
Overview
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.
