A new study published in the journal of Nature Communications showed that despite benign results on routine eye exams, chronic vision issues with even modest COVID-19 infections may be caused by continuous inflammation and nerve damage in the eyes. While loss of taste and smell are common COVID-19 symptoms, up to 35% of long-term COVID patients experience persistent ocular symptoms (POS), which disproportionately affect women. To address this, researchers thoroughly described POS and connected clinical symptoms overlooked by standard examinations with severe visual impairment. The study found important protein biomarkers for T cell-mediated neuroinflammation and ocular neuropathy using tear film proteomics. POS is a crippling syndrome that develops after COVID-19 recovery and is characterized by strabismus, ocular dysautonomia, and peripheral ocular neuropathy.
