Abstract

PURPOSE
To report a case of a patient with posterior ischemic optic neuropathy and abducens nerve palsy who responded to steroid therapy. CASE SUMMARY: A 47-year-old man visited our clinic with decreasing visual acuity and abduction limitation in his right eye, which suddenly started 4 days earlier. The best corrected visual acuity (BCVA) was 20/250 in the right eye and 20/20 in the left eye. Fundus examination showed normal in both eyes, and relative afferent pupillary defect was positive in the right eye. The visual field test showed a right central scotoma with inferior altitudinal field defect. In addition, the brain magnetic resonance imaging (MRI) was done. Orbit MRI, fluorescein angiography (FAG), and carotid ultrasonography results were normal. Therefore, the patient was diagnosed with non-arteritic posterior ischemic optic neuropathy. The systemic steroid therapy was started and tapered over a period of 5 weeks. At one month after treatment, the BCVA was 20/20 and abduction limitation in the right eye improved.
