硝子体手術を受けた糖尿病患者の手術適応となった網膜硝子体病変

Vitreoretinal lesions in eyes of diabetic patients who received vitreous surgery

要約　目的：硝子体手術を受けた糖尿病患者の網膜硝子体病変の頻度を検討した。

対象と方法：204例227眼の網膜硝子体病変を，1群：糖尿病網膜症（網膜症）に関連するものと，2群：関連しないものに分けて調査した。1群の病態は硝子体出血，黄斑浮腫，その他に，2群は網膜裂孔/網膜剝離，網膜/黄斑前膜，黄斑円孔，網膜静脈閉塞症，加齢黄斑変性，その他の亜群に分けた。

結果：1群は111眼（48.9％），2群は116眼（51.1％）で過半数を占めた。1群の硝子体出血が35.7％で最も多く，2群では網膜剝離/網膜裂孔が14.5％で多かった。2群の網膜症は軽症であった。

結論：糖尿病患者は半数以上が網膜症に関連しない網膜硝子体疾患で手術を受けた。

Abstract　Purpose: To report the incidence of vitreoretinal lesions in eyes of diabetic patients who received vitreous surgery.

Cases and Method: This retrospective study was made on 227 eyes of 204 cases. Vitreous surgery was performed in 111 eyes（48.9％）for vitreoretinal lesions directly associated with diabetic retinopathy（Group 1）. Surgery was performed in 116 eyes（51.1％）for vitreoretinal lesions not directly associated with diabetic retinopathy（Group 2）.

Results: Vitreous hemorrhage was present in 35.7％ of eyes and was the most frequent entity in Group 1. Vitreous surgery was performed for retinal detachment in 14.5％ of eyes and was the most frequent entity in Group 2. Diabetic retinopathy was either absent or mild in most of the eyes in Group 2.

Conclusion: Vitreous surgery was performed in more than 50％ of eyes for vitreoretinal lesions not directly associated with diabetic retinopathy.
