The occurrence of age-related macular degeneration in the presence of a transferred, confirmed COVID-19

BACKGROUND: COVID-19 can affect the eyes and both the anterior and posterior segments of the eye. Retinal complications associated with COVID-19 have been reported.

CLINICAL CASE DESCRIPTION: We present a clinical case of age-related macular degeneration that developed during the acute period of coronavirus infection. A patient with COVID-19 and pneumonia (CT-1) experienced sudden decrease in visual acuity within 1 month. A dark spot appeared in front of the left eye, which did not disappear despite eye movements, and distortion of objects was observed. The disease was manifested acutely. A complete ophthalmological examination revealed a sharp decrease in visual acuity and a positive Amsler test (distortion of lines at a distance of 30 cm). In the field of view, scotomas were noted in the center. Ophthalmoscopy revealed light and dark foci in the central macular zone of the retina. Cptical coherence tomography with an angiographic mode detected severe changes at the level of the neuroepithelium and retinal pigment epithelium with the formation of gray tissue. Aflibercept (approved for use in the Russian Federation, No. LP-003544) was intravitreally prescribed according to the clinical guidelines for treating age-related macular degeneration. After treatment with positive dynamics, visual acuity increased to 1.0, and the thickness of the retina decreased by 102 microns.

CONCLUSION: The key objective in making a correct diagnosis was the use of optical coherence tomography with an angiographic mode. This method allows the visualization of the retinal layers without invasion The angiography mode allows the assessment of the state of the foveolar avascular zone and the density and perfusion of blood vessels, which enable the diagnosis of age-related macular degeneration and choroidal neovascularization. Timely antiangiogenic treatment, that is, a single intraocular injection, completely restored the visual acuity and visual field and normalized the state of the retina according to objective data of optical coherence tomography with angiography mode.
