[Case of multiple macroaneurysms of the retinal arteries].

A 74-year-old female with acquired macroaneurysms of the retinal arteries of the left eye is presented. During a follow-up period of three years of this rare case, six macroaneurysms developed one after another. Three of them were treated by argon laser photocoagulation because of severe complications such as retinal haemorrhage and exudation onto the macula. However, recovery of visual function of the final stage following treatment was unsatisfactory. Concerning the unusual clinical course of this case, we speculate that severe arteriolosclerosis of the retinal vessels played a fundamental role in this pathological condition.
