Subfoveal Choroidal Neovascular Membrane Secondary to Idiopathic Intracranial Hypertension.

To present a rare case of subfoveal choroidal neovascular membrane (CNVM) secondary to idiopathic intracranial hypertension. A case was evaluated. A 21-year-old woman presented with a 2-week history of painless blurred vision in the right eye. She described initial metamorphopsia and intermittent bitemporal headaches lasting 30 minutes. She denied pain with eye movements and a history of trauma. Her body mass index was 49 kg/m. The visual acuity (VA) was 20/320 OD and 20/20 OS; there was no relative afferent pupillary defect. A dilated fundus examination showed bilateral optic disc edema and a subfoveal CNVM in the right eye. The patient was started on oral acetazolamide 500 mg twice daily and treated with 2 intravitreal antivascular endothelial growth factor (anti-VEGF) injections. Three months later, the VA was 20/30 in the right eye and the disc edema had improved. CNVMs in the setting of idiopathic intracranial hypertension-related papilledema may be subfoveal and have an excellent response to anti-VEGF agents.
