目的:白内障手術時に眼内内視鏡で毛様体を観察し,囊胞の有無とその状況についての報告。対象と方法:過去1年間に白内障手術を行った267例354眼を対象とした。男性108例138眼,女性159例216眼である。水晶体核を除去したのちに内視鏡を前房に挿入し,水晶体囊を通して毛様体の皺襞部と扁平部を観察した。結果:毛様体囊胞は17例(6.4%)にあった。両眼例はなかった。男性6例(10.2%),女性11例(4.1%)であり有意差があった(p<0.05)。平均年齢は囊胞群が69.4歳,非囊胞群が73.8歳であり有意差があった(p<0.05)。血清コレステロール値には,囊胞群と非囊胞群との間に有意差はなかった。結論:白内障患者での毛様体囊胞の頻度は354眼中17眼(4.8%)であり,平均年齢が低く男性に高かった。
Purpose:To report the incidence and associated features of ciliary cyst as detected by endoscopic observation during cataract surgery. Cases and Method:This study involved 354 eyes of 267 patients who received cataract surgery during a 12-month period. The series comrised 138 eyes of 108 males and 216 eyes of 159 females. An endoscope was inserted into the anterior chamber after removal of lens nucleus. Pars plicata and plana was observed through the lens cortex. Results:Ciliary cyst was detected in 17 cases(6.4%). The series comprised 6 males(10.2%)and 11 females(4.1%). The difference was significant(p<0.05). There was no case of bilateral involvement. The ages averaged 69.4 years for cases with cyliary cyst and 73.8 years for those without. The difference was significant(p<0.05). There was no difference between the two groups regarding levels of serum cholesterol. Conclusion:Cyst of ciliary body was present in 17 out of 354 eyes(4.8%). It was more frequent in younger age group and in males.
