白内障手術の際，球後注射により生じた水晶体の硝子体内脱臼の1例

Intravitreal dislocation of cataractous lens immediately following retrobulbar anesthesia

　50歳男子の成熟白内障摘出に際し球後麻酔を行つた所，水晶体が網膜上迄脱臼した。患者の体位は通常の仰臥位のままとし，ピン等による固定も行わず，ループを用いた円滑な水晶体全摘出術を行つた。その際特に留意したのは，強膜圧迫により水晶体を常に顕微鏡視野の中央に保つ事と，大量に脱出する硝子体に対し徹底したanteriorvitrectomyを行うという二つの点があつた。術後経過は良好で，視力は21日目に1.0に達し，4年間の追跡において認むべき合併症も無い。

Just before the routine cataract operation of a healthy 50-year-old policeman, the mature cataract-ous lens dislocated into the vitreous cavity resting on the retina immediately following retrobulbar anesthesia of 3 ml of xylocaine. Ocular massage was not done. The lens was successfully removed by a loop with the patient in the supine position. Under the operating microscope the lens was visualized in center of the vitreous cavity with the aid of scleral depression throughout the procedure. Massive vitreous loss was managed well by the complete anterior vitrectomy.
