Retinopathy associated with dermatomyositis (DM) is rare and was first described by Bruce in 1938. Purtscher retinopathy refers to a chorioretinopathy associated with indirect trauma characterized by funduscopic appearance with cotton-wool spots (CWS), retinal hemorrhages, optic disc edema, and Purtscher flecken (areas of inner retinal whitening), associated with reduced visual acuity. When typical retinal findings occur in the complete absence of trauma, the term Purtscher-like retinopathy is used. Purtscher-like retinopathy has been associated with multiple clinical entities, including acute pancreatitis, pancreatic adenocarcinoma, renal failure and many more.

A 21-year-old white woman presented to our emergency room with a 1-month history of fatigue, muscle aches, nausea, cutaneous rash, and 5 days of blurred vision in her left eye (OS). She presented with a malar rash and some violet raised papules erupting on her elbows and knees that were made worse by exposure to sunlight. Her arterial pressure was 115/70 mmHg. Best corrected visual acuity was 20/20 in her right eye (OD) and 20/100 in her OS.

A multimodal examination was carried out, which included complete ophthalmoscopic fundus examination, swept source-optical coherence tomography (SS-OCT), fluorescein angiography (FA), and optical coherence tomography angiography (OCTA), allowing a better understanding of the etiology and long-term sequelae.
