In a case of unilateral acute idiopathic maculopathy (UAIM) following hand, foot, and mouth disease, we aim to discuss the decreased perfusion of choriocapillaris secondary to systemic inflammation as shown by optical coherence tomography angiography (OCTA) and to assess the prognostic significance of bacillary layer detachment (BALAD). A 33-year-old male presented with a decrease of vision in the right eye (OD) for 5 days preceding viral prodromal symptoms and vesicular lesions on bilateral palms and soles along with vesicles and ulcers on the oral mucosa. The best-corrected visual acuity was finger counting at 1 meter distance in OD and 20/20 in his left eye (OS). Dilated fundus examination revealed a circular white-grey dome-shaped elevated lesion at the macula indicative of serous retinal detachment in OD. Spectral-domain optical coherence tomography demonstrated BALAD associated with adjacent subretinal and intraretinal fluid along with pigment epithelium detachment and disruption of ellipsoid and interdigitation zones. OCTA showed decreased choriocapillaris perfusion. All the investigations were normal in OS. The resolution of BALAD occurred during the first 2 days, which was followed by gradual improvement of choriocapillaris flow that lasted 2 months. UAIM is associated with hand, foot, and mouth disease. OCTA demonstrates both qualitative and quantitative data by detecting alterations in the choriocapillaris flow, which could be monitored during the disease course.
