緑内障手術により上脈絡膜出血をきたした2例

Two cases of suprachoroidal hemorrhage secondary to glaucoma surgery

　緑内障手術による上脈絡膜出血が2例2眼に生じた。1例は落屑症候群の79歳男性で，ad—vanced non-penetrating trabeculectomyの4日後に遅発性上脈絡膜出血が起こった。他の例は原発開放隅角緑内障の75歳男性で，suture canalization術中に，駆逐性上脈絡膜出血が生じた。両症例とも，硝子体手術と経強膜的血腫除去術を後日行った。両症例に共通して，高年齢と無水晶体眼があり，第1例には高血圧，無硝子体眼，術後低眼圧，第2例には高度近視が危険因子として存在した。このような危険因子がある患者での緑内障手術では十分な注意が必要である。

We observed two cases of suprachoroidal hemorrhage secondary to glaucoma surgery. One was a 79-year-old male with exfoliation syndrome. Delayed suprachoroidal hemorrhage occurred 4 days after non-penetrating trabeculectomy. The other was a 75-year-old male with primary open-angle glaucoma. Expulsive suprachoroidal hem-orrhage occurred during suture canalization. Both cases were treated by vitrectomy and transscleral drainage of he-matoma later. Both cases had advanced age and aphakia in common. One case had systemic hypertension, history of vitrectomy and postoperative hypotony, and the other had high myopia as risk factors. Due precaution is necessary in performing glaucoma surgery in patients with such risk factors.
