"You Thought You Recovered from COVID—But Your Pupils Are Telling a Darker Story."
"We’ve heard about COVID-19’s effects on lungs, heart, and brain... but what about your eyes? In this video, we explore how COVID-19 can affect something as small—but revealing—as your pupils."
"The SARS-CoV-2 virus enters our bodies through ACE2 receptors found in the lungs. But ACE2 is also present in neurons and glial cells, making the brain—and even your pupils—a target."
"Pupil size is controlled by the autonomic nervous system. So any disruption in the brain or nerves can be reflected in how your pupils behave."
"A team of Turkish researchers studied 58 patients during their COVID-19 infection and again 3 months later. They used high-precision devices to measure pupil size in different light conditions."
"The results were fascinating. Under dim and medium light, pupils were significantly smaller during active infection than after recovery. But under bright light, no major difference was seen."
"More revealing was the **pupil dilation response** after light was turned off. During infection, pupil expansion was **significantly slower at every time point**."
"Why does this matter? Because pupil function depends on a delicate balance between brainstem signals, autonomic nerves, and muscle response."
"The study raises the possibility that COVID-19 may cause 'central or peripheral nervous system disruption;—even without other neurological symptoms.
"It could be a sign of **subtle brainstem involvement**, or even direct viral effects on the nerves that control the eye."
