Unilateral Acute Idiopathic Maculopathy in Hand, Foot, and Mouth Disease.

A 35-year-old female presented with vision loss in her left eye. Visual acuity was counting fingers. Fundus examination revealed a hypopigmented discoid foveal lesion with granular hyperpigmentation (Fig. 1A). Fluorescein angiography showed a window-defect stippled hyperfluorescence with mild staining (Fig. 1B). Optical coherence tomography (Fig. 1C) and corresponding en face view (Fig. 1D) demonstrated a well-circumscribed discoid area of disruption and irregularity of the photoreceptor ellipsoid and interdigitation zones.
