川崎病3症例の眼底に特異な網脈絡膜所見を認めた。病変部位は片眼性で,網膜深部から色素上皮層と考えられ,境界鮮明な小型灰黄白色斑が後極部から赤道部にかけて散在し,その多くは不規則な線状の配列をなす。網膜血管の走行とは一致せず,網膜浮腫や混濁を病変周囲に認めず,黄灰白色斑は最長で4年経過した現在も不変である。螢光眼底撮影所見では,window defectの所見に一致する。これらの変化は現在までに川崎病の網膜症として報告されたいずれの所見とも一致せず,本症に特異性の高い病変と考えられた。
We evaluated 15 cases with Kawasaki disease during the foregoing 5-year period. We detected unique retinochoroidal lesions in 3: 1 male and 2 females aged 6, 8 and 11 years respectively. Unilat-eral involvement was the rule. Funduscopy showed multiple coalescent grayish-yellow patches dis-tributed in linear patterns in the posterior and equatorial retina. Fluorescein angiography showed window defects at the sites of the patches. The finding suggested that the lesion was located at the retinal pigment epithelium. The lesions simulated drusen. They seemed to have developed secondary to choroidal inflammation.
