Role of Multimodal Imaging in Purtscher Retinopathy

Purtscher retinopathy is a rare condition that occurs in patients with a history of trauma distant from the eyes. 1 Typical manifestations, including cotton wool spots, retinal hemorrhagesand optic disc swelling, are confined to the posterior pole and often appear bilaterally. The pathogenesis underlying Purtscher retinopathy is not clear, but might be related to the embolic occlusion of precapillary retinal arterioles. Diagnosis is usually made on clinical grounds and supported by fluorescein angiography. For the majority of cases, visual function could recover to various extents without treatment. 2 Multimodal imaging can be a useful tool in identifying lesions which are very subtle on clinical examination in a visually symptomatic patient.
