Abstract

Coronavirus infection COVID19 is an acute respiratory viral disease, which in most cases is severe and leads to the development of various complications known as post-COVID syndrome.

Post-covid syndrome or long-covid syndrome is a consequence of coronavirus infection (COVID-19), while 20% of those who have been ill suffer from long-term symptoms, the duration of which varies greatly and is more than 12 weeks.

According to the WHO, the post-covid syndrome includes 33 symptoms, while in younger people who have been ill, the incidence of this symptom complex is much higher. According to the literature, post-COVID syndrome may reappear 3-6 months after clinical recovery. This condition is characterized by various non-specific symptoms, which can be manifested by dysfunction of individual organs, skin vasculitis, neurological symptoms up to the development of mental disorders.

Summing up, it should be noted that during the pandemic period, certain experience has been accumulated regarding ophthalmic problems. The data obtained are sometimes contradictory, but it is already clear that ophthalmic disorders in COVID-19 can be leading along with damage to other organs. Perhaps a new disease leads to an exacerbation of an existing or manifestation of dormant ophthalmopathology. Regardless of what is the cause, it is necessary to remain vigilant about the state of the organ of vision both in the immediate and long-term period after a new coronavirus infection.
