光輝小斑のみられる網膜動脈閉塞症の光凝固治療について

Effects of photocoagulation on retinal artery occlusion with bright plaque

（1）44歳男子の右眼にみられた特異な網膜動脈閉塞症と，61歳男手の右眼網膜中心動脈閉塞症（不完全型）と思われる症例において，光輝小斑のみられる動脈分岐部に対し治療の目的でキセノン光凝固を行った。

（2）症例1は光凝固後約2週間目には視力の改善がみられ，経過中の血管走行の変化は回復過程を推察するうえで重要な所見と思われた。

（3）症例2では上耳側働脈第1分岐部に著明な光輝小斑がみられた症例で，光凝固後の視力，視野についてその経過を報告した。

Two cases of retinal artery occlusion were treated with xenon photocoagulation therapy.

Case 1, a 44-year-old male, was first seen with complaint of blurring of vision with a peculiar reti-nal artery branch occlusion in his right eye.

Case 2, a 61-year-old male with right central artery occlusion (incomplete type), had a distinct bright plaque at the bifurcation of the first branch from the superior temporal artery.

In both cases, photocoagulation was applied to the portion of the bifurcation of arteriole. In case 1, vision began to improve two weeks after photo-coagulation, and simultaneous change of vascular pattern was seen.
