Case 7. Fovea-threatening peripheral Coats disease in a 27-year-old man who was successfully treated in the past and returned with recurring extrafoveal exudation; the visual acuity (VA) was 20/20. He adopted a nasal sleep position during this time (inset 1). A A color fundus shows the previous peripheral and paracentral temporal scars of laser treatment and the new site of recurring hemorrhages and exudation (arrow). A spectral-domain optical coherence tomography (SD-OCT) image confirms the presence of temporal intraretinal hyperreflective exudates. B Four weeks after the patient changed to a lateral-down high sleep position (inset 2) followed by laser treatment of the abnormal dilated vessels (arrow), partial dehydration of the exudates is seen. C Three months later, the VA improved to 20/20 and the fundus/SD-OCT images show complete resolution of the exudation
