A forty-four-year-old female patient known for FSHD type I, with unremarkable past ocular history, complained of progressive visual acuity deterioration during a routine ophthalmological visit. Best-corrected visual acuity (BCVA) was 1.0 decimal Snellen equivalent bilaterally. Dilated fundus examination showed evidence of retinal Coats-like disease in the left eye, while the right eye showed significant retinal vascular tortuosity. Multimodal examinations (OCT scans and FA-fluorescein angiography) revealed large areas of retinal ischemia, thus confirming a retinal vascular disorder compatible with the diagnosis of Coats-like disease. Left eye laser photocoagulation of the ischemic areas was performed to avoid neovascular complications that had not been detected during follow-up visits (12 months), and BCVA in the left eye remained stable at 1.0 decimals Snellen equivalent. Coats-like disease in a patient affected by FSHD type I should always be screened even in the absence of any prior ocular diseases. Guidelines concerning the ophthalmological management of adults affected by FSHD are lacking. Based on this case, we recommend performing a yearly complete ophthalmological checkup with dilated fundus examination and retinal imaging. Patients should, furthermore, be encouraged to seek medical attention when noticing deterioration of visual acuity or other visual symptoms in order to avoid missing potential sight-threatening ocular complications.
