要約 目的:開放隅角緑内障と落屑緑内障でのTrabectome単独手術と強膜深層切除併用線維柱帯切開術単独手術(LOTD)の臨床経過についての検討。対象と方法:対象は3か月以上経過観察できた原発開放隅角緑内障(広義)と落屑緑内障である。症例は,67例75眼(Trabectome),46例50眼(LOTD)である。両群の背景には差がなかった。結果:眼圧下降率は,LOTD群で,全体の症例群,術前眼圧が20mmHg以上の群,落屑緑内障群でTrabectome群よりも有意に高かった。術後の併発症ではLOTD群が有意に術後血液逆流の頻度が高かった(p=0.0005)。その他の併発症には差がなく重篤なものはなかった。結論:LOTDが眼圧下降効果は大きいが,症例によってはTrabectomeも選択されるべき手術であると思われる。
Abstract. Purpose:To report and compare the outcome of Trabectome and trabeculotomy with deep sclerotomy. Cases and Method:This study was made on 125 eyes with primary open-angle glaucoma or exfolidation glaucoma. Trabectome was performed on 75 eyes and trabeculotomy with deep sclerotomy on 50 eyes. Results:Reduction in intraocular pressure(IOP)3 months after surgery was significantly greater in eyes following trabeculotomy with deep sclerotomy than Trabectome(p=0.04). Reduction in IOP was more apparent as a whole, in eyes with IOP higher than 20 mmHg, and in eyes with exfoliation. Postoperative hyphema was more frequent after trabeculotomy with deep sclerotomy(p=0.0005). Otherwise, there was no difference in complications between the two methods. Conclusion:Trabeculotomy with deep sclerotomy showed greater IOP-reduction effect. Trabectome may be indicated for some cases of glaucoma.
