Purtscher-like Retinopathy Associated with Crimean-Congo Hemorrhagic Fever: A Case Report

Purpose: To describe retinal findings and spectral-domain optical coherence tomographic (SD-OCT) features of a patient with Crimean-Congo hemorrhagic fever (CCHF) presenting as Purtscher-like retinopathy. Case report: A 70-year-old woman presented with the emerging bilateral blurring of vision. She had been diagnosed with CCHF one week ago and hospitalized in another hospital for treatment of disease. Fundoscopy of the patient revealed cotton-wool spots, retinal whitening areas, and few retinal hemorrhages in a Purtscher-like configuration in both eyes. Spectral-domain optical coherence tomography revealed inner retinal hyperreflectivity corresponding to the cotton-wool spots in both eyes, and also showed subretinal fluid in the left eye. Without any treatment retinal lesions and inner retinal hyperreflectivity on SD-OCT regressed within one month. Conclusion: Crimean-Congo hemorrhagic fever is known to cause mild ocular disease, and may also cause Purtscher-like retinopathy. It is important to aware of the ocular findings of CCHF.
