Multimodal Imaging of Unilateral Acute Maculopathy Associated with Hand, Foot, and Mouth Disease: A Case Series.

We described clinical and multimodal imaging findings in 4 patients with unilateral acute idiopathic maculopathy (UAIM) associated with hand, foot, and mouth disease. Four eyes of 4 patients (3 women and 1 man) with a mean age of 35 years (range: 24-40 years) were included. A bacillary detachment was observed in 3 out of the 4 eyes and was strongly suspected in the remaining eye. This particular detachment was resolved within 5-10 days in our series. A choriocapillaris involvement was supported by the multimodal imaging findings. On indocyanine green angiography, a hypofluorescence was observed throughout the sequence, and OCT angiography showed a defect of the choriocapillaris perfusion. In this case series, a complete multimodal retinal assessment allowed identifying the choriocapillaris as the primary tissue involved in UAIM associated with coxsackie virus infection. In 3 out of our 4 cases, a bacillary detachment with a transient evolution was identified.
