Purpose:
To report a case of acute macular neuroretinopathy in a patient with Susac syndrome.
Methods:
Case report.
Results:
A 39-year-old male patient presented with severe headache, photopsias, and a sudden onset of hearing loss in the right ear. Fluorescein angiography of the right eye revealed multiple branch retinal artery occlusions. Clinical presentation of encephalopathy, hearing loss, and branch retinal artery occlusions, along with characteristic magnetic resonance imaging findings, led to a diagnosis of Susac syndrome. Despite aggressive immunosuppression for four months, the patient later presented with acute macular neuroretinopathy in the left eye.
Conclusion:
Acute macular neuroretinopathy and Susac is a new association of two well-defined disorders. The concurrence of both disorders supports retinal ischemia as the proximate cause of acute macular neuroretinopathy and inflammation as a potential etiology.
