抗凝固療法の奏効した網膜中心静脈閉塞症（切迫期）の4例

Anticoagulant therapy for central retinal vein occlusion

　4例の中心静脈閉塞症の切迫期に対し抗凝固療法を試み，いずれの症例においても有効であった。抗凝固剤としては，クマリン系統のWafarinSodiumを使用し，量のcontrolは凝固機構の内的因子・外的因子にsensitiveなトロンボテストを指標とした。ワーファリン使用中に拮抗剤であるK₁を投与しなければならない様な副作用は生じなかった。

Four cases with impending central retinal vein occlusion were treated by systemic anticoagulant therapy. Usually, warfarin sodium was given at the daily dosis of 2 to 3mg. The maintenance dosis was determined by thrombotest values which was to be kept between 10 and 30%. Striking improvement of fundus findings occurred in 2 to 3 weeks accom-panied by significant improvements in visual acuity. No side effects, including hemorrhage from the urinary tract, were encountered throughout the cases.
