Purpose: To elucidate clinical and angiographic features of retinal manifestations in cat scratch disease. Methods: Clinical characteristics as well as fluorescein and indocyanine green (ICG) angiographic features were reviewed in 4 consecutive patients with retinal manifestations caused by serologically confirmed cat scratch disease. Results: A subretinal to intraretinal granuloma at the upper margin of the optic disc was found in 3 patients, while 1 patient developed subretinal to intraretinal granuloma in the midperiphery with serous retinal detachment. Fluorescein angiography revealed the abnormal vascular network of the peripapillary granuloma in the early phase followed by its dye leakage toward the late phase. Indocyanine green angiography demonstrated more clearly the abnormal vascular network with its minimal dye leakage than did fluorescein angiography. In contrast, only the late dye leakage was noted from granuloma of the midperipheral fundus by fluorescein angiography in one patient. Indocyanine green angiography detected no choroidal lesions other than the retinal lesions delineated by fluorescein angiography. The granulomas disappeared in response to a 4-week course of sulfamethoxazole-trimethoprim combined with steroids. Conclusions: Granuloma with abnormal vascular network as revealed by fluorescein and ICG angiography is characteristic of retinal manifestations in cat scratch disease.
