Retinal changes after coronavirus infection

The SARS-CoV-2 coronavirus infection pandemic has caused 667 million cases. COVID-19 is a severe acute respiratory infection caused by the SARS-CoV-2 coronavirus. The virus primarily affects the respiratory system and runs the gamut from respiratory infection, to acute respiratory distress syndrome. Various ophthalmologic manifestations in both the anterior and posterior segment of the eye are increasingly reported in the literature. Purpose. Present clinical cases of retinal changes after coronavirus infection. Material and methods. We present two clinical observations of patients with ophthalmic manifestations in the posterior segment of the eyes that developed after a coronavirus infection. All patients underwent ophthalmological examination including visometry, anterior segment biomicroscopy, and ophthalmoscopy with non-contact Volk 78D lens, optical coherence tomography (OCT) of macular area and angioregim OCT (DRI OCT Triton plus, Japan). Treatment and recommendations were individualized according to ophthalmological indications. Results. Stabilization of retinal changes after coronavirus infection. There was an increase in maximum corrected visual acuity (MCOZ), reduction of macular edema. Conclusion. It is necessary to pay attention to complaints of the visual organ in patients with coronavirus infection in the early stages of the disease and in the nearest months after recovery. Our clinical observations show the need for further study of pathogenesis, clinic and treatment methods of ophthalmologic complications associated with coronavirus infection.
