増殖性硝子体網膜症grade Aを伴う網膜剥離で強膜バックル後に硝子体切除術を要した症例の検討

Retinal detachments with grade A vitreoretinopathy treated by scleral buckling and vitrectomy

（26B2-24）　Grade Aの増殖性硝子体網膜症を伴った網膜剥離147眼を回顧的に評価した。全例に強膜締結術を行い，129眼はこれのみで治癒し，18眼ではさらに硝子体手術の追加が必要であった。硝子体手術を必要とした症例群での危険因子は，15フォトカウント／msec以上の前房フレア値，裂孔不明，白内障手術の既往，硝子体出血，脈絡膜剥離，（＋＋）以上の強い硝子体混濁であった。このような症例に対しては，grade Aであっても，当初から硝子体手術を考慮すべきである。

We reviewed 147 eyes of retinal detachment with grade A proliferative vitreoretinopathy (PVR) . All the eyes were treated by scleral buckling. Reattachment was obtained in 129 eyes with this procedure alone and in 18 eyes after additional vitreous surgery. Risk factors in the 18 eyes requiring additional vitreous surgery were : aqueous flare over 15 photocount/msec, unidentified retinal breaks, past history of cataract surgery, choroidal detachment, vitreous hemorrhage and vitreous haze of + + or more. We advocate additional vitreous surgery as the primary procedure for retinal detachment grade A PVR with these risk factors.
