The main symptoms of acute primary angle-closure glaucoma (PACG) include pain in the head and/or the eyes in addition to the characteristic halo and blurred vision. When loss of vision is accompanied by such pain, PACG is usually suspected. However, no information has been available regarding painless acute angle-closure glaucoma. Recently, we treated a patient with painless acute PACG mimicking amaurosis fugax as a type of transient ischemic attack. Generally, amaurosis fugax causes transient monocular loss of vision due to occlusion of the ophthalmic artery. The formation of microemboli derived from the heart or carotid artery and/or the occurrence of some hemodynamic abnormality due to arteriosclerosis is closely related to amaurosis fugax, and most cases are complicated by intracranial or extracranial arterial lesions. In the present case, we provisionally diagnosed transient amaurosis fugax which, however, was shown by additional ocular testing to be painless PACG. Herein we describe our diagnostic process and the outcome.

A 66-year-old Taiwanese aboriginal male had complained of right-side blurred vision for 2 months, especially when reading. He had a 10-year history of hypertension and cardiovascular disease. His best-corrected visual acuity was 20/25 in each eye. Ophthalmoscopy revealed asymmetrical cupping, but a normal disc. Humphrey perimetry showed an upper homonymous paracentral quadrantanopic defect. Brain magnetic resonance imaging showed an infarction in the left lower calcarine area over the extrastriate (V2/V3) cortical area and a narrowing of the left middle and posterior cerebral arteries due to severe arteriosclerosis.
