To describe the medium-term ophthalmological findings in patients recovering from COVID-19. Risk Manag Healthc Policy. In animal experiments (cat, mice), various eye diseases such as uveitis, retinitis and optic neuritis could be triggered by betacoronaviruses indicating an direct uptake into the eye [27]. Further studies with more participants with and without acute ocular symptoms are necessary for final evidence.

This study evaluated the ocular findings of patients who recovered from COVID-19 with a mean time of 8236.4 days after the onset of the disease's first symptoms. Studies on animal coronavirus infection models have reported retinal involvement evident as retinal vasculitis, retinal degeneration or collapse of the blood-retinal barrier [35, 36]. Therefore, this prospective cross-sectional study sought to examine potential long-term functional and morphological impairment in eyes of COVID-19 patients 3 months after recovery. They were considered to be at the recovery phase of the disease when the time interval between the diseases first symptoms and the eye examination was at least 30 days.
