A case report of ocular ischemic syndrome with neovascular glaucoma secondary to Moya-Moya disease

Abstract

We present a rare case of ocular ischemic syndrome with neovascular glaucoma secondary to Moya-Moya disease in a 49-year-old male patient with complaints of headache, giddiness and gradual diminution of vision in his left eye. A detailed ophthalmic examination followed by investigations of Optical coherence tomography and fundus fluorescein angiography along with carotid doppler and magnetic resonance angiography with Diamox intervention was performed and a diagnosis of ocular ischemic syndrome secondary to Moya-Moya disease has been made. The patient was advised pan retinal photocoagulation in both eyes with intravitreal ranibizumab injection in the left eye for macular edema under guarded visual prognosis. In spite of treatment with three sittings of pan retinal photocoagulation along with intravitreal ranibizumab, the patient’s vision deteriorated. It is one of the cases of ocular ischemic syndrome where there is no visual improvement in spite of treatment as it is secondary to a cause like Moya-Moya disease.
