New research from Northwestern Medicine reveals link between long COVID and eye health
New research from Northwestern Medicine reveals link between long COVID and eye health

Patients with long COVID experienced a significant reduction in the density of blood vessels in the back of the eye, compared to healthy individuals.

The change in blood vessels in the deep part of the retina supports the hypothesis that long COVID affects similar blood vessels in other parts of the body, like the brain, which can potentially contribute to the symptoms of long COVID such as memory loss, brain fog and fatigue.

Retinal tissue and microvasculature loss in COVID-19 infection
Retinal tissue & microvasculature loss in COVID19 infection: Retinal volume was signif⬇️in outer 3 mm of macula in severe COVID19 group (p = 0.02). Total retinal vessel density was signif⬇️in severe COVID-19 vs normal/ mild COVID19 (p = 0.004 & 0.0057).

Autopsies have previously evidenced SARS viral persistence in gastrointestinal tissues including ocular tissues. This study detected SARS RNA in ocular fluids/tissue in 61% of cases; cornea 42%, horoid/sclera 50%, lens 53%, retina 35%, optic nerve 59%.

Comprehensive analysis of study thread on Twitter: New Study: Covid found to infect the eyes and replicate with in them: virus found in eyes months after infection:

'our data give us reason to believe that so-called long-Covid symptoms may include degenerative retinal disease.'

Study leader says.

Acute viral retinitis in patients with COVID-19 "severe blindness could be associated with SARS-CoV-2 infection... physicians should consider the possibility of coronavirus infection in patients with an abnormal fundus or suddenly vision loss."
