要約 目的:黄斑円孔が併発した裂孔原性網膜剝離の特徴と10年間の手術成績の報告。対象と方法:2012年までの10年間に初回手術を行った28例28眼を対象とし,診療録の記述をもとに検索した。男性20眼,女性8眼であった。結果:同期間に硝子体手術が行われた裂孔原性網膜剝離の総数は1,325眼で,黄斑円孔が併発した28眼の頻度は2.1%であった。両群間に,発症年齢の平均,剝離が持続した推定期間についての有意差はなかった。28眼での黄斑以外の裂孔数は,平均3.3個で,57%が増殖網膜症であった。28眼の眼軸長の平均は,罹患眼では24.0±1.8mm,僚眼では24.6±1.4mmであった。全例に硝子体手術を行い,20眼では内境界膜を剝離した。27眼(96%)で網膜が復位し,17眼(61%)で黄斑円孔が閉鎖した。手術の6か月後の視力平均はlogMAR 1.0で,網膜剝離の推定持続期間と関連していた。内境界膜剝離は,黄斑円孔の閉鎖率と術後視力には影響しなかった。結論:黄斑円孔が併発した裂孔原性網膜剝離では,これが併発しない症例よりも重症例が多く,視力転帰が不良であった。内境界膜剝離は,黄斑円孔の閉鎖率と術後視力には影響しなかった。
Abstract. Purpose:To present a 10-year review of rhegmatognous retinal detachment with additional macular hole. Cases and Method:This retrospective study was made on 28 eyes of 28 cases who received initial surgery by us during 10 years through 2012. The series comprised 20 males and 8 females. Findings:The present 28 eyes approximated 2.1% of a total of 1,325 eyes that received vitreous surgery for rhegmatogenous retinal detachment during the same period. There was no difference in the age of onset or duration of retinal detachment before surgery between the two groups. An average of 3.3 retinal breaks was present in the 28 eyes. Proliferative vitreoretinopathy was pre-sent in 16 eyes(57%). Axial length in 28 cases averaged 24.0±1.8 mm in the affected and 24.6±1.4 mm in the fellow eyes. All the eyes were treated by vitreous surgery. Additional peeling of internal limi-ting membrane(ILM)was performed in 20 eyes. The retina became reattached in 27 eyes(96%). Macular hole closed in 17 eyes(61%). Visual acuity averaged 1.0 logMAR six months after surgery and was related with duration of retinal detachment. ILM peeling was not related with closure of macular hole or visual outcome. Conclusion:Coexistence of macular hole showed a higher incidence of PVR and resulted in poorer visual outcome in rhegmatogenous retinal detachment. ILM peeling failed to improve the rate of closure of macular hole or visual outcome.
