巨大裂孔網膜剥離の手術成績

Outcome of surgery for retinal detachment with giant tear

　巨大裂孔網膜剥離5例5眼の手術成績を検討した。年齢は21歳から60歳で，全例男性であった。5例中4例に初回硝子体手術を施行し，うち3例は液体パーフルオロカーボン（PFC）を使用した。1例は輪状締結術を施行した。2例に再手術を必要としたが，最終的に5例中4例が復位した。1例は増殖硝子体網膜症のため復位を得られなかった。PFCの網膜下残留，網膜のslippageなどの合併症は認めず，PFC使用は有用な手段であった。

We operated on 5 eyes of retinal detachment with giant retinal tear. All were males. Their ages ranged from 21 to 60 years. The retinal tear extended over 90 degrees in 1 eye, 120 degrees in 2 eyes, and 180 degrees in 2 eyes. Encircling surgery with scleral buckling was performed in 1 eye. Pars plana vitrectomy was performed in 4 eyes. Perfluorocarbon was additionally used in 3 of the 4 eyes. The retina was anatomically reattached in 4 eyes including 2 eyes that required multiple surgeries. Retinal detachment persisted in the other one eye due to proliferative vitreo-retinopathy. Complications have been absent including subretinal spread of perfluorocarbon or slippage of the retina after perfluorocarbon/air exchange. These cases illustrate that perfluorocarbon is a useful adjunct during surgery for retinal detachment with giant tear.
