黄斑円孔網膜剝離に対する耳側強膜短縮術併用の硝子体手術の成績

Outcome of vitrectomy with or without temporal scleral shortening for macular hole retinal detachment

要約　黄斑円孔網膜剝離33例33眼に対する硝子体手術を過去9年間に行った。うち9眼は最大幅6mmの耳側強膜短縮を併用した。両群とも，原則として黄斑上の膜様組織の除去を行い，全例にガスタンポナーデを行った。術後の再剝離が強膜非短縮群24眼中9眼（38％）に生じたが，短縮群では全例で復位が得られた。黄斑円孔網膜剝離では，硝子体手術に耳側強膜短縮を併用して眼軸長を短縮することで初回復位率を向上できる可能性がある。

Abstract.　We performed vitreous surgery for macular hole detachment in 33 eyes of 33 patients during the past 9 years. Nine of the 33 eyes received additional temporal scleral shortening by up to 6 mm. Epiretinal membrane peeling was performed whenever feasible. Gas tamponade was performed in all the eyes. The retina became redetached in 9 of 24 eyes（38％）treated by vitreous surgery alone. The retina became reattached in all the 9 eyes（100％）treated by additional scleral shortening,Temporal scleral shortening would contribute to better outcome in macular hole detachment by shortening the ocular axial length.
