Eye damage in COVID-19. Part 2: posterior segment complications, neuro-ophthalmic manifestations, vaccination and risk factors

ABSTRACT

Posterior eye segment involvement in COVID-19 has varied manifestations vascular, inflammatory, and neuronal. All of them are triggered by SARS-CoV-2 virus but they cannot be viewed as exclusively specific to COVID-19. According to the literature, the mean age of the patients varies from 17 to 75 with the median of 50 years. The median duration between the appearance of ophthalmic symptoms and the detection of COVID-19 was 12 days. The disease affects both men and women equally. Direct exposure to the virus, immune-mediated tissue damage, activation of the coagulation system, the prothrombotic state caused by a viral infection, concomitant diseases and medications used in the treatment contribute to the development of eye pathologies. Ophthalmologists should be aware of the possible relations of posterior eye segment pathologies, orbit and neuro-ophthalmic disorders with SARS-CoV-2, as well as the possible exacerbation of chronic forms of inflammatory eye diseases and autoimmune disorders due to anti-COVID-19 vaccination. © 2023, Real Time LLC.
