Clinical findings in unilateral acute idiopathic maculopathy New findings in acute idiopathic maculopathy

摘要

We report a case of unilateral acute idiopathic maculopathy (UAIM) with new clinical findings. A 34-year-old Japanese man had a neurosensory retinal detachment (~5 disk diameters) with yellowish-white exudates at the macula in the left eye (visual acuity (VA) 0.4). Fluorescein angiography (FA) showed early hypofluorescent spots and late pooling in the subretinal space. Three weeks after onset, indocyanine green angiography (IA) showed numerous hypofluorescent spots at the lesion. Optical coherence tomography (OCT) showed subretinal fluids and an elevated choroidal lesion with low reflectivity, suggesting choroidal edema. The VA and fundus appearance spontaneously resolved without treatment three months after onset. The VA was 1.0 six months after onset. Irregular pigmentation remained at the macular lesion. The main UAIM pathology may be outer retinal layer and retinal pigment epithelial inflammation. FA, IA, and OCT suggested that choroidal inflammation may be involved in the pathogenesis of UAIM.
