Coronavirus side effects: The virus could cause eye symptoms including nodules on eyeballs


There have been many reports of symptoms of COVID-19 affecting the eyes including conjunctivitis and sore eyes. Now researchers warn of nodules on the eyeballs caused by the virus.

Images produced by the MRI showed at least one nodule found in the region of the eye which is integral to central vision.

The cause for these nodules was hypothesised by the researchers to be linked with inflammation triggered by COVID-19 and a common manifestation of the virus.

Lead author of the study, Dr Augustin Lecler from the University of Paris said of the findings: “We showed that a few patients with severe COVID-19 from the French COVID-19 cohort had one or several nodules of the posterior pole of the globe.

“This is the first time these findings have been described using MRI.”


When a person has chronic inflammation, their body’s inflammatory response can eventually start damaging healthy cells, tissues, and organs.

Over time, this can lead to DNA damage, tissue death, and internal scarring.

All of these are linked to ailing body parts and development of several diseases.

Eye problems caused by COVID-19

The COVID-19 virus may cause eye problems such as enlarged, red blood vessels, swollen eyelids, excessive watering and increased discharge.

“Your eyes are lined by mucous membranes, a thick protective fluid,” explains Optimax. “Primarily, this membrane is to stop dirt and grit from entering your body through the eyes, as well as ensuring that your eyes stay well hydrated.

“However, with COVID-19, this mucous membrane becomes an easy point of access for the virus to enter your body.”
