To discuss the aetiology and treatment of peripapillary CNVM due to idiopathic intracranial hypertension
Retina clinic of a tertiary eye care centre
A young female presented with c/o gradual decrease in vision. Her visual acuity was 20/200p in right eye and 20/25 in left eye. The colour vision was defective in right eye and normal in left eye. The fundus examination revealed disc edema with minimal subretinal fluid in both eyes and subretinal haemorrhage in peripapillary area in right eye. The OCT revealed subretinal neovascular membrane, subretinal fluid and haemorrhage. HVF showed enlargement of blind spot in both eyes. The FFA showed leakage in both eyes. The opening CSF pressure showed 35cm of H2O. A diagnosis of IIH with peripapillary CNVM was made.The patient was advised weight reduction and was started on acetazolamide tablet. The patient received anti-VEGF injection in both eyes for CNVM.
The disc edema reduced and the CNVM regressed with anti-VEGF injections.
Peripapillary CNVM can occur due to disc edema in cases of idiopathic intracranial hypertension and responds to anti-VEGF along with reduction of CSF pressure.
