網膜剥離術後に網膜色素上皮剥離様病変と乳頭浮腫がみられた症例

Serous detachment of the retinal pigment epithelium with disc edema following retinal detachment surgery

（1）61歳，男子左眼の裂孔原性網膜剥離術後に網膜色素上皮剥離様病変と乳頭浮腫のみられた極めて稀な症例を経験した．

（2）網膜色素上皮剥離様病変は脈絡膜毛細血管の透過性亢進による漏出の結果おこったものと考えられた．

（3）乳頭浮腫は脈絡膜循環系に由来する乳頭網目状表在性毛細血管網の透過性亢進によるものであると考えられた．

（4）この二つの変化はいずれも網膜剥離という病的状態に網膜剥離手術という外科的侵襲が加わり，脈絡膜循環系に障害をきたしたために生じたものと推測された．

A 61-year-old male presented with rhegmatogenous retinal detachment in the superior quadrant of his left eye. Two weeks after apparently successful sur-gery using local silicon rubber exoplant and cryo-application, numerous small areas of serous detach-ment of the retinal pigment epithelium (RPE) be-came manifest in the fundus area where the retinal detachment was initially present. Optic disc edema developed 9 weeks after surgery. These fundus lesions subsided leaving no sequealae 7 months postoperative-ly.

Fluorescein angiographic findings seemed to indi-cate that the serous detachment of the RPE resulted from serous leakage from the choriocapillaris. The disc edema seemed to have resulted from the hyperpermiability of the racemose, superficial disc capillaries. The disc and RPE lesions appeared to be related with the surgical manipulation in the pre-disposed eye.
