Visual and neurological complications of COVID-19

The review summarizes the evidence of visual and neurological complications in the acute stage of COVID-19 and in post-COVID syndrome. Neurological symptom complexes, and cerebrovascular disorders are described. Ophthalmologic manifestations may be a typical sign of COVID-19 onset, but they may also develop several weeks after recovery. The spectrum of neuro-ophthalmological manifestations in most cases includes optic neuritis, optic disc edema, optic neuropathy, and venous thrombosis. Ophthalmologists should be aware of the possible associations of ocular diseases with COVID-19 in order to diagnose and initiate an early treatment for life and vision threatening complications.
