Abstract
Description
(1-1)瞳孔ブロックを解除し前後房の圧差を解消して隅角を開大する目的で患者X1の右眼に対してレーザー虹彩切開術を行った。
(2-1)患者Y1は69歳女性であり、主訴は左眼の視力低下であった。初診時所見は視力は右眼1.0(1.2)、左眼0.3(0.6)、眼圧は右眼15mmHg、左眼14mmHgであった。細隙灯顕微鏡検査では両眼ともフルオレセインで染色される点状表層角膜症がみられた。角膜実質には軽度の浮腫による混濁がみられ、角膜内皮面には反帰光線で観察されるdark spotが散在性にみられた。前房内に細胞やflare等の炎症所見はみられなかった。中間透光体には両眼ともに核・皮質白内障がみられた。スペキュラマイクロスコープで、角膜内皮細胞密度は右眼1,959cells/mm2,左眼692cells/mm2であり、角膜厚は右眼609μmであった。初診時の所見よりFuchs' 角膜内皮ジストロフィと診断した。グラナテック(リパスジル塩酸塩水和物点眼液)を2回/日で69日間使用した。69日間使用した後に最菲薄部角膜厚を測定すると575μmであった(図4)。角膜厚が減少しており浮腫が改善されていることが判明した。
