| Abstract |
|
Anterior ischemic optic neuropathy is the general term of disease causing visual disturbance by stenosis or obstruction of nutritional vessels of optic nerve with or without organic lesion. Patient was a 64 year old man who visited our hospital because of further evaluation of sudden visual loss and loss of lower visual field of left eye. In this case, it is observed that visual acuity of left eye was decreased suddenly and visual field of left eye was constricted on inferior area on 4 month after initial visit, visual acuity and visual field of right eye were affected. On the visual evoked potential, bilateral optic pathway disturbance finding is seen, faulty perfusion of the disc capillary and absence or decrease of the choroidal filling are seen by fluorescein angiography. Thus, anterior ischemic optic neuropathy is suspected by history, visual field, visual evoked potential and fluorescein angiography. This case was presented and a brief review of literatures has been described. |
