(18-D-21) 過去3年間に硝子体手術を行い,術後6か月以上追跡できた糖尿病網膜症299眼を検索した。171眼(57%)では水晶体を温存した。128眼(43%)では前または後嚢を残して水晶体を摘出した。両群の間に,術後の虹彩新生血管または血管新生緑内障の頻度に差はなかった。この所見は,術前に硝子体出血のみがある例,線維血管膜がある例,牽引性網膜剥離のある例で差はなかった。硝子体再出血は水晶体を温存した群で有意に多かった。硝子体腔を空気で置換した例には眼内レンズ挿入術を同時に行ったが,同様に良好な結果が得られ,前眼部合併症も少なく,有用な方法であると考えられた。
We reviewed 299 diabetic eyes treated by vitrectomy during the past 3 years. The cases were followed up for 6 months or longer after surgery. The lens was kept intact in 171 eyes (57%). The lens was removed leaving either the anterior or posterior capsule in 128 eyes (43% ) . There was no difference between two groups regarding the postoperative incidence of postoperative rubeosis iridis or neovascular glaucoma. This finding was independent of whether vitrectomy was performed for vitreous hemorrhage, fibrovascular proliferation or tractional retinal detachment. Vitreous rebleeding was significantly more frequent in the former group. Simultaneous intraocular lens implantation in 70 eyes treated by fluid/air exchange also showed lesser incidence of postoperative complications, suggesting the usefulness of this procedure.
