Recent studies have shown concerns that the PFIZER-BionTech Covid-199 vaccines can have a serious effect on the cubic but potentially the cornea, especially the inner layer, the inner layer. Turkish scientists performed Journal eye mechanics, The study examined the change in the cornea of 64 patients before and after receiving both the capacity of the vaccine. In immediate vision loss, the study found that the vaccine has reduced the thicker cornea and the number of endothelial cells, and over time, it causes structural changes that can affect eye health. According to the Daily Mail, experts warn that these changes can be harmless in the short term, but it can be dangerous for those with existing eye conditions or cornea transplantation.
Paikotabid vaccine associated with corneal cell loss, swelling and changed structure
The researchers showed that the average thickness of the cornea increased from 528 to 542 micrometers after an increase of about 2 % after two topic doses. The number of endothelial cells, which keeps the cornea clean, decreased by 8 % from 2,597 to 2,378 cells per square millimeters. This remains in a safe range for a healthy individual, but such a decrease can cause serious risks for people with low baseline due to diseases such as aging, vision surgery or nutritional disorders of Fuchs.
In addition, this study rises from 39 to 42 to point out the increase in cell size changes (variable coefficients), suggesting that the cornea caterpillar is stressed. The number of cells that maintain healthy hexagonal shapes also dropped from 50 %to 48 %. As reported by Daily Mail, these signs do not immediately affect vision, but they can compromise when the long -term clarity and function of the cornea persist.
Scientists urge attention, but they do not oppose vaccinations.
This study, which analyzes 128 eyes using Sirius Corneal terrain and TOMEY EM-4000 SPECULAR MICROSCOPY, is recommended to stop vaccination efforts. Rather, it requires continuous monitoring of the known eye vulnerability of the cornea of the known eyes. Researchers stressed that the observed changes could be a temporary response to stress or inflammation and could be solved over time.Nevertheless, they warned that “the inner skin of the endothelial should be monitored closely to those with low or corneal transplantation.” According to Daily Mail, this adds conventional concerns about rare side effects of MRNA vaccines for myocarditis and pericardialitis, especially young men. Researchers plan to continue to track the participants to determine whether the initial cornea change progresses or whether it stabilizes over time. Experts emphasize the need for a larger co -study study to verify these results and assess clinical relevance. Until then, ophthalmologists can consider eye checkups before vaccination for high -risk patients as preventive measures.
