We report a rare case of acute macular neuroretinoapthy masquerading as retrobulbar optic neuritis.
His best corrected visual acuity(BCVA) was 20/20 OD and 20/20 OS. Pupillary reflex was normal and relative afferent pupillary defect was not found. Ocular movement test was normal and pain on ocular movement was not noticed. Ophthalmoscopic examination of the left eye revealed multiple exudate lining toward fovea in the nasal macula. A Humphrey visual field study identified small paracentral scotoma. Spectral domain optical coherence tomography (SD-OCT, HRA-OCT, Heidelberg Engineering , Heidelberg, Germany) aimed at the lesions showed a hyper-reflective lesion located in the outer plexiform layer an inflammatory cell infiltration. Fluorescent angiography was normal in the macula, but show late leak at the disc.
The patient was diagnosed as acute macular neuroretinopathy and he was treated with prednisolone 60mg. His subjective symptom was improved and paracentral scotoma was disappeared, the lesions changed on the SD-OCT: the hyper-reflective lesion disappeared, and the outer plexiform layer and IS/OS junction showed thinning.
Acute macular neuroretinopathy is rare disease, we report the case with SD-OCT and mfERG.
