title: [A case of retinochoroidal optic neuropathy].
abstract: The patient was a 59-year-old male with impaired left vision. Before he was referred to this hospital, he was diagnosed as having optic nerve injury due to the trauma of a severe bruise on his left eye caused by a traffic accident, and relative afferent pupillary defect (RAPD) was negative. On his first examination in this department, RAPD was negative and funduscopy of the left eye demonstrated hyperemia of the optic disc and mild opacification at the posterior pole. Fluorescein fundus angiography showed circular hyperfluorescence around the optic disc and transverse linear hyperfluorescence appearing above and below the macula. From these findings a diagnosis of choloidal rupture was made. The form of choloidal rupture suggested an early stage of evulsion of the optic nerve. The impairment of visual acuity seemed to be caused by choloidal circulatory disturbance. The patient was therefore, had traumatic retinocholoidal optic neuropathy complicated by the rupture of the choloidal around the optic disc, disturbance of the optic disc, and opacification of the retinochoroid.
