Purtscher-Like Retinopathy After Acute Ischemic Colitis

Purpose: To describe a case of Purtscher retinopathy, a rare microvascular process hypothesized to have an occlusive etiology. Methods: A single case was evaluated. Results: A 72-year-old White woman presented with acute, painless bilateral vision loss and severe abdominal pain. She was hospitalized for ischemic colitis of unknown origin. Although her symptoms were improving, funduscopic examination findings of retinal hemorrhages, cotton-wool spots, and Purtscher flecken prompted a referral to ophthalmology. The diagnosis of Purtscher-like retinopathy was made, and treatment of her precipitating ischemic colitis resolved her visual symptoms. Conclusions: Purtscher-like retinopathy is a rare clinical diagnosis of exclusion. By describing a previously unreported etiology, this case may improve our understanding of the pathogenesis, management, and treatment of this rare retinopathy.
