title: Anterior ischemic optic neuropathy in patient with hereditary spherocytosis and coexisting angioid streaks.
abstract: Purpose. To describe a rare case of hereditary spherocytosis (HE) with angioid streaks that developed anterior ischemic optic neuropathy (AION). Method. Case report. Results. A 53-year-old woman with HE had a 3-day history of blurred vision in the lower hemifield in the left eye. At presentation, her visual acuity was 20/20 OD and 20/200 OS. Perimetric testing showed a relative scotoma in the superior parafoveal region in the right eye and an inferior altitudinal field defect in the left eye. Fundus examination demonstrated angioid streaks in both eyes with swelling of the optic disc in the left eye. Both parvovirus B19 immunoglobulin M and immunoglobulin G were identified in her serum.  Conclusions. This is the first report of AION in HE and coexisting angioid streaks. The infection by parvovirus itself might be involved in the development of AION.
