Regression of a Peripapillary Neovascular Membrane Following Lumbar Peritoneal Shunting in a Case of Idiopathic Intracranial Hypertension

Abstract

This report concerns a case of Idiopathic Intracranial Hypertension (IIH) in a man treated with lumbar peritoneal shunting. Despite resolution of papilloedema a central scotoma remained and evaluation in the retinal department revealed peripapillary choroidal neovascularisation (CNV). During 10 months follow up fundus appearance and Optical Coherence Tomographic (OCT) findings improved although his visual acuity did not change. The case is presented as an example of improvement of a neovascular membrane following treatment of raised intracranial pressure.
