Abstract Purpose:To report bilateral nonarteritic ischemic optic neuropathy in an adult with ischemic heart disease.

Case:A 39-year-old male was referred to us for slowly progressive visual failure since 3 months before.

Findings and Clinical Course:Corrected visual acuity was 0.7 in either eye. Both eyes showed critical flicker frequency of 10 Hz and enlarged Mariotte scotoma. Magnetic resonance imaging(MRI)showed a high signal of the optic nerve in both eyes. Two courses of corticosteroid pulse therapy proved ineffective. He was diagnosed as optic neuritis of unknown etiology. Four months later, the visual acuity declined to 0.2 right and 0.05 left. He was then detected to have ischemic heart disease involving two branches of coronary artery, and received two sessions of percutaneous coronary angioplasty. Five months later, visual acuity improved to 1.0 in either eye with persistent central scotoma. He was eventually diagnosed with bilateral nonarteritic ischemic optic neuropathy.

Conclusion:The present case of bilateral nonarteritic ischemic optic neuropathy failed to respond to corticosteroid pulse therapy. Coronary angioplasty was followed by improved cardiac functions and visual acuity.
