[A case of subacute bacterial endocarditis showing acute macular neuroretinopathy-like lesions].

PURPOSE

We report one case of mimic fundus lesions with acute macular neuroretinopathy due to subacute bacterial endocarditis.

CASE

A 55-year-old male had about a 1 DD reddish petal-shaped lesion at the level of the retinal pigment epithelium in the macula and a white lesion about 1/6 DD at the level of the retinal pigment epithelium in the upper fovea. Fluorescein angiography showed the reddish lesion to be hypofluorescence due to a filling defect and indocyanine green angiography showed the hypofluorescence was due to a circulatory disturbance of the choriocapillaris. Additionally, we found that there was a severe choroidal circulatory obstruction in the white lesion on the retinal pigment epithelium. After the disappearance of the white lesion, secondary retinal pigment epithelium atrophy remained.

CONCLUSION

The macular lesions of acute macular neuroretinopathy were ischaemic lesions of the retinal pigment epithelium formed because of a disturbance at the level of the choriocapillaris.
