術後網膜剥離防止を目的とした部分的網脈絡膜切除術

New techniques to prevent postoperative retinal detachment after local excision of the retina and choroid

　眼内微小銅線異物の1例と，眼内腫瘍の1例に，網脈絡膜部分切除を施行した。手術は術後の網膜剥離を防止することを主目的とし，ナイロン糸による網脈絡膜固定を行い，かつ，バックリングにより切除部を囲むことにより，術後剥離を防止することに成功した。本術式は，非磁性の微小眼内異物や，眼内良性の腫瘍の場合，症例によつては，有用な方法である。

In order to prevent postoperative retinal de-tachment after local excision of the retina and chroid, a combined technique consisting of fixa-tion of the retina with nylon sutures and buckling of the sclera was attempted in a case with an intraocular small copper wire (0.16 × 0.7mm) and a case with benign choroidal tumor. In these two cases, nonrhegmatogenous retinal detachment extending toward the posterior pole was unsuc cessfully treated by previous photocoagulation. Local excision of the retina and choroid together with the foreign body ortumor was decided to preserve the visual acuity.
