Retinal arterial obstruction: The etiology and visual result.

ABSTRACT

A series of 17 consecutive patients with central retinal artery obstruction (CRAO; 15 patients, 16 eyes) and branch retinal arterial obstruction (BRAO, two patients) were studied at Siriraj Hospital between January 1994 and June 1997 with respect to cause, associated factors and visual result. The study group compressed 13 men and four women with a mean age of 48 years. Hyperlipidemia was the most common underlying disorder in those patients aged less than 45 years. Retinal emboli and increased intraocular pressure were identified as the ocular in three patients. The visual result improved in four patients, two each of whom had interval times from onset to treatment of less than six hours and more than 48 hours. No light perception vision at the initial examination occurred in 3 patients and none had improved vision.
