Abstract

PURPOSE: To evaluate the relationship between the lesions of the MEWDS, retinal dysfunction and the cause of decreased visual acuity. METHODS: A patient with a medical history, retinal finding, and the fluorescein angiographic findings consistent with the diagnosis of MEWDS is described. Full field ERG and mfERG were performed and the results was analyzed to find the relationship the visual acuity and the fluorescein angiographic findings. RESULTS: mfERG of the involved eye shows diffuse depression of the amplitude accentuated by focal areas of steep depression thought to correspond to white spot and full field ERG shows generalized depressed signal. The mfERG abnormalities seen at the presentation resolved with the resolution of visual symptoms after 1 month. CONCLUSIONS: The major symptoms of the patient is due to the decreased retinal function and the mfERG is seem to be the useful and safe tool for evaluation of the retinal function and the relationship between the symptoms and the white dots.
