要約 目的:初診時に高齢者に特有な中心性漿液性脈絡網膜症に似た所見を示し,経過とともに原田病の典型像を呈した報告。症例:62歳男性が6か月前からの右眼の変視症と視力低下で紹介され受診した。所見:矯正視力は右0.6,左1.2であった。右眼黄斑部に漿液性網膜剝離があり,蛍光眼底造影で1個の点状の過蛍光と網膜下への強い色素貯留があった。インドシアニングリーン蛍光眼底造影早期に充盈遅延があった。光干渉断層計で漿液性網膜剝離とフィブリン様の中等度反射があった。無治療での経過観察で,7か月後に右眼視力が1.0に回復したが,左眼に網膜剝離が生じ,両眼に乳頭浮腫が起こった。その2か月後に網膜剝離は消褪し,さらに3か月後には両眼が夕焼け状眼底になった。結論:原田病の初期では,高齢者に特有な中心性漿液性脈絡網膜症に似た所見を呈することがある。
Abstract. Purpose:To report a case of Vogt-Koyanagi-Harada(VKH)disease simulating central serous chorioretinopathy in senile persons. Case:A 62-year-old male presented with metamorphopsia and impaired vision in the right eye since 6 months before. Findings:Corrected visual acuity was 0.6 right and 1.2 left. The right eye showed serous retinal detachment in the macular area. Fluorescein angiography showed one point of leakage followed by dye pooling in the subretinal space. Indocyanine green angiography showed delayed dye filling in the choroid. Optical coherence tomography showed serous retinal detachment and moderately reflective reflex suggestive of fibrinous accumulation. Seven months later,serous retinal detachment appeared in the left eye with edema of optic disc in both eyes. Retinal detachment disappeared 2 months later. Both eyes showed sunset-glow fundus another 3 months later. Conclusion:This case illustrates that VKH disease may initially manifest clinical features simulating central serous chorioretinopathy.
