Eye pain can be a symptom of COVID-19. While the virus primarily impacts the respiratory system, it can affect various parts of the body, including the eyes. Ocular symptoms, including discomfort or pain, have been reported by individuals infected with SARS-CoV-2. Eye involvement is one way the infection can manifest beyond typical respiratory signs.
Eye Pain as a COVID-19 Symptom
Eye pain, when linked to COVID-19, is often described as a dull ache, pressure, or soreness felt behind the eyes. This discomfort can arise from inflammation, dry eyes, or direct viral infection of ocular tissues. Studies indicate a prevalence of around 16% among COVID-19 patients.
The pain typically emerges within the first week of infection and often subsides within two weeks. It can affect one or both eyes, and its severity can fluctuate, intensifying in more severe cases.
Other Ocular Manifestations of COVID-19
Beyond pain, COVID-19 can lead to other eye symptoms. Conjunctivitis, commonly known as pink eye, is a frequently reported ocular manifestation. It affects approximately 1% to 3% of individuals with COVID-19, though some studies indicate higher figures, reaching up to 31.6% in some patient groups. Symptoms of conjunctivitis include redness, swelling, itching, watery eyes, and a gritty sensation. In rare instances, conjunctivitis has been the sole presenting symptom of COVID-19.
Another common ocular symptom is photophobia, or increased sensitivity to light, reported in about 10% to 18% of patients. This is related to inflammation or irritation caused by the virus. Other symptoms include dry eyes, blurred vision, and eye discharge.
When to Seek Medical Advice
If you experience persistent eye pain or discomfort, especially with other potential COVID-19 symptoms, seek medical attention. Significant redness, swelling, changes in vision, increased sensitivity to light, or excessive tearing and discharge warrant consulting a healthcare professional. This is particularly relevant if you have had known exposure to COVID-19 or are experiencing common symptoms like fever, cough, or shortness of breath.
Contacting your doctor or an eye specialist before visiting a clinic is recommended. An eye care provider can perform a thorough examination to assess your symptoms and rule out other conditions.
Distinguishing Eye Pain from Other Causes
Eye pain is a general symptom that can arise from many conditions unrelated to COVID-19. Common causes include eye strain from prolonged screen use, seasonal allergies, dry eyes, migraines, or sinus infections. Similarly, conjunctivitis can be caused by various viruses, bacteria, chemicals, or allergens, not exclusively by the SARS-CoV-2 virus.
