眼内内視鏡による毛様体扁平部囊胞と関連因子

Factors related to endoscopically observed cyst of ciliary pars plana

要約　目的：眼内内視鏡で観察した毛様体扁平部囊胞に関する知見の報告。対象と方法：過去3年間に白内障手術を行った883眼を対象とした。男性377眼，女性506眼で，水晶体核を除去した後，上方の強角膜創から内視鏡を挿入し，水晶体囊越しに毛様体扁平部を観察した。結果：囊胞は66眼（7.5％）にあり，うち8眼（12.1％）では両眼性であった。囊胞の存在率は男性10.9％，女性4.9％であり，有意差があった（p＜0.05）。平均年齢は囊胞群74.2歳，無囊胞群73.3歳で有意差はなかった。高血圧は囊胞群の53％，無囊胞群の27.5％にあり，有意差があった（p＜0.05）。両眼に囊胞がある8眼中7眼（87.5％）に高血圧があった。結論：白内障患者での毛様体囊胞は男性に多く，高血圧者に多い。

Abstract.　Purpose：To report the incidence and related factors for cyst of ciliary body as observed by endoscope. Cases and Method：This study was made on 883 eyes that received cataract surgery during a 3-year-period. The series comprised 377 males and 506 females. An endoscope was inserted after removal of lens nucleus. Pars plicata and plana was observed through the lens cortex. Results：Cyst of ciliary body was detected in 66 eyes（7.5％）. It was bilateral in 8 cases（12.1％）. It was present in 10.9％ males and in 4.9％ of females. The difference was significant（p＜0.05）. The age averaged 74.2 years in persons with cyst and 73.3 years in those without. Systemic hypertension was present in 53％ of persons with cyst and in 27.5％ of those without. The difference was significant. Conclusion：Ciliary cyst was more frequent in males and in persons with systemic hypertension.
