Susac's syndrome in a 27-year-old female

A 27-year-old woman was referred by the neurologist for ophthalmic examination. She had a history of headache, visual loss in her right eye, four-limb paresthesia, and behavioral changes over the previous 10 months. The patient complained of tinnitus and hearing loss for two weeks. The patient was initially diagnosed with multiple sclerosis, but auditory and retinal involvement [small branch retinal artery occlusion in fluorescein angiography] raised the possibility of Susac's syndrome

Multifocal electroretinogram in clinically significant diabetic macular edema

To explore the multifocal electroretinogram in patients with nonproliferative diabetic retinopathy with clinically-significant macular edema. Forty-one eyes with clinically significant macular edema were tested. The latencies and amplitudes of average responses of 5 eccentric rings from 0 to 26 degrees relative to the fixation point were compared with normal values obtained from 13 nondiabetic subjects. Local electroretinogram responses were significantly delayed and decreased in amplitude in patients with clinically-significant macular edema. Multifocal electroretinogram can be used to quantify the visual function in clinically significant macular edema
