Shocking Eye and Brain Disorders Found in COVID-19 Patients in Nepal

Thailand Medical News: A new case report from Nepal has highlighted disturbing findings that COVID-19 can lead to serious eye and brain issues, even in relatively young individuals without major health problems. Doctors from four medical institutions in Nepal have documented three unusual but serious cases of neuro-ophthalmic complications—that is, vision problems linked to the brain and nerves—following SARS-CoV-2 infection.


Shocking Eye and Brain Disorders Found in COVID-19 Patients in Nepal

The study was led by medical researchers from B. P. Koirala Lions Centre for Ophthalmic Studies and the Department of Neurology at Tribhuvan University Teaching Hospital, along with collaborators from B. P. Smriti Hospital and Biratnagar Eye Hospital. This Thailand Medical News report presents three cases, each showing different neurological eye disorders after COVID-19, pointing toward the virus’s possible ability to trigger inflammation and blood clots that affect not only the lungs, but also the eyes and the brain.  concerning was the discovery that COVID-19 infections can lead to damage of the optic nerves.
 
Case One: Vision Loss Due to Optic Nerve Damage
A 42-year-old man who had recovered from mild COVID-19 suddenly woke up one morning unable to see clearly in his right eye. Medical tests ruled out diabetes, stroke, and other usual causes. He was diagnosed with nonarteritic ischemic optic neuropathy, a condition where blood flow to the optic nerve is blocked. Although some vision returned over six months, parts of his visual field were permanently lost, and the optic nerve showed signs of long-term damage.
 
Case Two: COVID Triggers Blood Clots in Brain Veins
The second case involved a 41-year-old woman who was only three days into her COVID-19 infection when she developed severe headaches, vomiting, and vision problems in both eyes. Scans revealed that she had a rare but dangerous clot in her brain’s venous sinuses, leading to papilledema, or swelling of the optic disc. She required immediate treatment with blood thinners and other medications. Her vision later improved, but residual optic nerve damage remained.
 
Case Three: Eye Movement Problems and Stroke in a Young Man
The third patient, a 40-year-old diabetic man, had been hospitalized with COVID-19 pneumonia and later developed a stroke and blood clots in his leg. He began experiencing double vision and difficulty moving one eye outward due to a sixth cranial nerve palsy. Tests showed damage to the part of the brain that controls vision. Though his eye movements recovered after three months, his visual field defect did not improve.
 
What the Study Reveals
The cases suggest that COVID-19 may cause harmful effects far beyond the lungs. The authors believe that the virus may create a hypercoagulable state in the body—essentially making the blood more likely to clot—which can lead to vision-threatening conditions like optic nerve stroke, brain venous clo ts, and eye movement paralysis. These complications were observed even in patients with no prior serious health issues, raising concerns about long-term risks of SARS-CoV-2.
 
The study findings were published in the peer-reviewed journal: Case Reports in Ophthalmological Medicine
