Explaining that new symptoms of the epidemic were detected in the unvaccinated or incompletely vaccinated group, Prof. Dr. Alper Sener said:
“At the beginning of the epidemic, people with Kovid-19 had clinical redness and watering in their eyes. Later on, we saw that these affected the optic nerve in a way that caused damage to the eye. Our patient received a single dose of vaccine.
He has a 50 percent decrease in vision in one eye. We do not know whether this reduction in vision will return. It’s too early to comment. The treatment process continues. In this case, the importance of the vaccine is revealed once again. Kovid-19 vaccines protect people not only from the virus, but also from the symptoms that may occur after the disease.
Şener stated that after the diagnosis of Kovid-19, the number of patients with vision problems increased rapidly, and that they were conducting a scientific study on this issue.
“We looked at the optic nerve conduction velocity in the patients whose Kovid-19 PCR test became negative and whose isolation period was over, in people who had no visual problems. We saw that these were reduced by 30 percent. When we look clinically, the patients said that they did not see as sharply as before Kovid-19.
This loss of vision is caused either by the formation of clots in the vessels feeding the optic nerve or the virus invading the optic nerve alone. I think the problem is caused by the virus affecting the optic nerves. Our patients do not realize this health problem in the early period.”
