Sudden painless visual loss after initiation of antihypertensive therapy: case report.

Sudden, painless visual loss occurs in retinal disorders that stem from primary ocular as well as systemic diseases. Vascular insufficiency is one of the leading causes of sudden painless unilateral loss of vision. Early recognition of ischemic optic neuropathy, and rapid correction of hypotension, might improve the recovery from ischemic optic neuropathy. The case of a 40-year-old man who, after antihypertensive therapy for malign hypertension, developed sudden, painless loss of vision in both his eyes is discussed.
