( – “Long COVID” continues to confuse doctors as patients suffer from debilitating symptoms months after their initial infection. A new study suggests that patients with COVID who may be long-haul carriers can be diagnosed by looking closely. According to scientists, the loss of nerve fibers and the increase in major immune cells on the surface of the eye may be a way to identify the long-term effects of the virus.

The changes are especially pronounced among people with the following neurological symptoms: Loss of taste and smell, Headache, dizziness, numbness, neuropathic pain.Weil Cornell Medical Doctor-Qatar has a long COVID Characterized by various symptoms It lasts for more than 4 weeks after the acute phase of infection and is not explained by alternative diagnosis.

CCM has been used to identify nerve damage and inflammatory changes caused by diabetic neuropathy. Multiple sclerosis, And fibromyalgia ..

Forty people who recovered from a COVID-19 infection identified one to six months ago completed a questionnaire from the National Institute for Health and Care Technology (NICE). The data was used to find out if they had a long Covid and the total score ranged from 0 to 28. Neurological symptoms were present in 22 of 40 (55%) and 13 of 29 (45%) at 4 and 12 weeks. , According to the survey results published in each British Journal of Offtalmology..

Participants’ corneas were then scanned using CCM to look for small nerve fiber damage and dendritic cell density.These play an important role in the primary Immune system reaction By capturing and presenting antigens from invading organisms.

Corneal scans were compared to scans of 30 healthy people who were not infected with COVID.

The result is 55% COVID patients There were no clinical signs of pneumonia. Twenty-eight percent had clinical signs of pneumonia that did not require oxygen therapy. 10% were hospitalized for pneumonia and received oxygen therapy, and 8% were admitted to the intensive care unit for pneumonia.

Patients with neurological symptoms 4 weeks after recovery from acute COVID-19 by corneal scan may have more corneal nerve fiber damage and loss and more dendritic cells than non-virus-infected patients It became clear. People without neurological symptoms had the same number of corneal nerve fibers as those who were not infected with COVID, but had a higher number of dendritic cells.

“The answer to the questionnaire is Long COVID symptoms It was strongly correlated with the loss of corneal nerve fibers, “said research author Professor Rayaz Malik. statement..

He states that it was an observational study, so the cause could not be determined and only a small number of participants were involved.

“As far as we know, this is the first study to report loss and increase in corneal nerves. [dendritic cell] density In a patient who has recovered From COVID-19, especially in subjects with persistent symptoms consistent with long COVID, “he adds. “We show that patients with long COVID have evidence of small nerve fiber damage associated with long COVID severity, neuropathy and musculoskeletal symptoms. Corneal cofocal microscopic examination. May be clinically useful as a rapid objective ophthalmic examination to evaluate patients with long COVID. “
