網膜剥離の顕微鏡下手術—網膜下液排出法

Drainage of subretinal fluid under operating microscope

　顕微鏡下で，6〜25倍の強拡大の下に網膜下液の排出を行うと，十分に排液を行うことができ，しかも排液に伴う合併症を1％以下に抑えることができ，より安全である。

A reliable technique for the drainage of sub-retinal fluid under operating microscope has been used in 250 cases of retinal detachment during the past 19-month period. The procedure is performed in the following steps.

A scleral incision is made exposing the choroidwith a scleral blade 1 to 2 mm in length. Diather-my is applied on the lips of the incision so that a choroidal knuckle appears. The knuckle is treated by diathermy to prevent choroidal hemorrhage.A suture is then passed across the wound with a spatula needle with 4-0 synthetic non-absorbable suture. The choroid is perforated with a round sharp needle.
