A study of human cornea can help scientists to identify potential nerve damage and future chances of long covid.
Covid-19 is said to affect human body on a long term, including harming major organs such as brain, heart, kidneys etc.
Patients with neurological symptoms are most likely to be affected by long covid. This can be identified through corneal confocal microscopy.
Other indications obtained include presence of large number of immune cells and also loss of nerve fibre on the surface of cornea.
Neurological symptoms such as loss of smell, taste, brain fog, dizziness, numbness, neurological pain were all signs of long covid.
Cornea scan was performed on all the patients. The results were analyzed to see if there were small damage to nerve fibres and decrease in dendritic cells.
The patients were made to answer questionnaire to collect information on neurological, dermatological, psychological, gastrointestinal, throat, nose and eye symptoms post covid.
Neurological symptoms were detected after four months of getting diagnosed of covid-19. This provides insight into evolution of human immunity.
