Retinal branch vein occlusion: a study of argon laser photocoagulation in the treatment of macular oedema.

Abstract

A control trial is reported which demonstrates that treatment with argon laser photocoagulation to certain patients with macular oedema following a branch vein occlusion does not alter significantly their visual prognosis. It confirms that patients with an intact perifoveal capillary arcade have a better prognosis than those with a broken arcade.
