Unilateral acute idiopathic maculopathy (UAIM) is a rare disorder that has been linked with coxsackie virus. It was initially described by Yannuzzi et al. [1] in a series of 9 patients in 1991. A viral prodrome is common. We aim to add to the literature a case of challenging visual symptoms associated with resolved hand-foot-mouth disease, suggesting presumed UAIM.A 51-year-old male, with no significant past ocular or medical history, complained of distortion and noticed 4 persistent small round defects in the center of his vision in the left eye. He presented to our practice 5 months after the onset of symptoms, which had been unchanged during that time span. Notably, two months prior to the onset of visual symptoms, the patient had had multiple erythematous vesicular lesions on the palms of his hands and the soles of his feet. He also had pharyngitis, along with vesicles around the mouth. No antibody testing for coxsackie virus was done at the time. By the time of his presentation with visual complaints, these symptoms had resolved.On examination, the patient presented with best corrected visual acuity 20/20 OD and 20/25 OS. His manifest refraction was -2.50 sphere OU. Intraocular pressure was 12 OD and 14 OS. There was no evidence of intraocular inflammation. Anterior segment was unremarkable. Fundus examination revealed hyperpigmented spots surrounded by hypopigmented atrophic changes in the left macula (Figure 1). Fluorescein angiography revealed early blockage and window defect corresponding to the pigmentary changes (Figure 2). OCT imaging showed thickening at the level of the outer retina and IS/OS line disruption at the site of these spots (Figure 3).

 In cases of unilateral acute idiopathic maculopathy, typical funduscopic evaluation reveals retinal edema with yellowish-white exudative changes that eventually become hypopigmented spots with absence of exudation [1,2]. Initial fluorescein angiography reveals hyperfluorescence secondary to staining at the level of the retinal pigment epithelium (RPE). At later stages, RPE atrophy develops and fluorescein angiography reveals hypofluorescence secondary to blockage by RPE hyperpigmentation [1,2]. Matsushita et al. have reported thickening at the level of the outer retina/RPE and photoreceptor IS/OS line irregularities as detected by SD-OCT that change over time with at least partial restoration [3]. Fundus autofluorescence has been described as a stippled hyperautofluorescence pattern in the acute phase followed by a more stellate pattern in the late phase. ICG has demonstrated choroidal vascular inflammation [4].Originally described by Robinson et al. in 1958, hand-foot-mouth disease occurs as an outbreak of vesicular and ulcerative stomatitis associated with a maculopapular rash and vesicles on the hands and feet [5]. Hand-foot-mouth disease is usually a self limited condition in children. Most frequently, it is associated with coxsackie virus serotype A16 and enterovirus 71.Differential diagnosis includes central serous retinopathy and idiopathic choroidal neovascularization. In this case, the presentation included a visual complaint of recent onset of four simultaneous scotomas that correlated with four macular lesions, in the setting of hand-foot-mouth disease, strongly favoring the diagnosis of UAIM.This case demonstrates the clinical presentation, including fluorescein angiography and OCT findings, of presumed unilateral acute idiopathic maculopathy. Patients may present with scotomas that are consistent with fundus examination and changes that are consistent with an outer retinopathy. Patients with active or a recent history of hand-foot-mouth disease can demonstrate these macular changes.
