漿液性中心性脈絡網膜症に対するargon laser光凝固の臨床効果及び螢光眼底造影所見の変化

The fluorescein angiography findings and argon laser coagulation results of central serous chorioretinopathy

緒言

　漿液性中心性脈絡網膜症（idiopathic central ser-ous chorioretinopathy，以下ICSC）は過去20年の間に，中国においても目立ってふえてきた眼病の一種である。1960年代以来螢光眼底血管造影術が導入されて，これによって本病の脈絡毛細血管の透過性亢進，網膜下漿液貯留・網膜色素上皮あるいは神経上皮剥離及び螢光漏出点などの新しい所見が発見され，本病の発病機序及び治療方法の研究にはなはだ意義ある貢献をした^1）。

　最近レーザー光凝固を応用して螢光漏出点を閉鎖する治療方法は，単純の薬物療法のみに頼る過去の療法に比して，より良好な効果をあげうると一般に公認され，すでに数少なくない研究報告がされている^2-4）。

39 eyes of 38 cases of central serous chorioret-inopathy were fluorecein angiographied, and 53leakaged spots with different shapes were found intotal cases, only 2 eyes of non-leakaged in 2 cases.

27 eyes of 26 cases were coagulated by argonlaser. Visual acuities before laser coagulation wereless than 0.9 in 19 eyes and more than 1.0 only 8eyes. But after laser coagulation, visual acuitieswere improved notably, more than 1.0 with 25 eyesand only 2 eyes less than 0.9. Among 27 lasercoagulated eyes, 18 eyes were fluorecein angiogra-phied again and there were 17 non-leakaged eyesand one eye with a new leakaged spot at anotherplace. Besides, in this thesis we discussed the indica-tion, contraindication and method of argon lasercoagulation.

According to our clinical experiences, we con-sider that laser coagulation is the most effectivemethod in the treatment of central serous chorio-retinopathy.
