COVID-19 and the EYE




The new coronavirus behind the pandemic causes a respiratory illness called COVID-19. Its most common symptoms are a fever, coughing, and breathing problems. Rarely, it also can cause an eye infection called conjunctivitis. Based on data so far, doctors believe that 1%-3% of people with COVID-19 will get conjunctivitis, also called pinkeye. It happens when the virus infects a tissue called conjunctiva, which covers the white part of your eye or the inside of your eyelids.

Symptoms are:
  • ·         Red
  • ·         Swollen
  • ·         Itchy


If you have conjunctivitis, it doesn’t necessarily mean you have COVID-19. The more likely causes are the many different viruses, bacteria, chemicals, and allergens that can irritate your eyes. Many forms of conjunctivitis go away with over-the-counter treatments in about 1-2 weeks. But if you also have a fever, cough, or shortness of breath, ask your doctor what, if anything, you should do. Call before you head to a hospital or a medical center to see if it’s safe for you to visit and for any instructions for your arrival.

The new coronavirus, named SARS-CoV-2, gets passed on primarily through droplets from a cough or a sneeze. These particles most often enter through your nose or mouth as well as your eyes. It’s also possible to catch the virus if you touch a contaminated countertop, doorknob, or other surfaces. But this doesn’t seem to be the main way the virus spreads.

If you have conjunctivitis from COVID-19, you may infect others with SARS-CoV-2 if you touch your eyes and then touch people or surfaces without washing or disinfecting your hands. Avoid touching your face, especially the mucous membranes in your mouth, nose, and eyes.

How to Protect Your Eyes


Guarding your eyes — as well as your hands, nose, and mouth — can slow the spread of coronavirus. Here are some ways to you can keep your eyes safe and healthy during this coronavirus outbreak. Like everyone, be sure to wash your hands often and stay home whenever you can. If you go out, keep 6 feet away from others.

It also may be a good idea to:

Wear glasses. If you wear contact lenses, switch to glasses for a bit. That may help keep your hands away from your eyes. Also, the lenses may help protect your eyes from any respiratory droplets. If you don’t wear glasses, try sunglasses. And if you’re caring for someone ill, don safety glasses or goggles.

Stock up eye medication. Check with your insurer to see if you can refill glaucoma drops and other essential prescriptions in advance. You might be able to get a 3-month supply. Ask your doctor or pharmacist for any help.

Don’t rub your eyes. It can be a hard habit to break. Moistening drops may help ease itchiness. Wash your hands for 20 seconds before and after you do it. If you must touch your eyes, use a tissue instead of your fingers.


Expect changes to eye exams and procedures

You should wear a mask to your appointment. If you do not have a mask, one may be provided for you.

·         The clinic may ask you to wait outside, or in your car, instead of in the normal waiting room. This is to protect you, the other patients, and the office staff from possible virus exposure in crowded waiting areas.

·         The clinic is likely restricting the number of people that enter. If you do not need someone to be there with you for the actual appointment, please do not bring anyone into the building with you.

·         Your temperature may be checked on entry to the building.

·         Your eye doctor may use a special plastic breath shield on the slit lamp machine they use to look into your eyes. They will also wear a mask, and may also wear gloves, goggles or a plastic shield over their eyes.

·         Your doctor may ask you to wait to speak until after your eye exam is complete. Then they can talk with you and answer questions when they can be a safe distance from you.


You will be asked to follow certain precautions


·         If you have a cough or a fever, or have been in close contact with someone who has these symptoms, you must call your doctor’s office ahead of time and let them know. If your visit is not an emergency, you may need to stay home.

·         If you arrive sick, your doctor may ask you to return home. If you have a problem that cannot wait to be seen, you will be asked to wait in a special room away from other patients. The clinic staff and your physician may wear additional protective equipment, such as gowns and gloves.

·         If you need to cough or sneeze during your exam, move back from the slit lamp microscope machine. Bury your face in the crook of your arm or cover your face with a tissue. Wash your hands with soap and water right away.

Li Wenliang, MD, Ophthalmologist, Wuhan


The 33-year-old doctor was the first to raise the alarm about the coronavirus in late December 2019. Using the Chinese social media platform Weibo, Li attempted to warn his colleagues about a cluster of SARS-like pneumonia cases. As his posts went viral, he realized that he “would probably be punished." Within days, he was summoned by Chinese officials and forced to sign a letter accusing him of "making false comments" that had "severely disturbed the social order". A copy of that letter was later posted on Weibo.

Following the incident, Dr. Li returned to work and, unfortunately, contracted the virus from an asymptomatic glaucoma patient in early January. In several interviews with Chinese media, he said that the patient eventually developed a fever and CT scans showed an unknown virus in her lung. Soon after, he started coughing, became febrile and was hospitalized. Tests confirmed he was infected with the coronavirus on Jan. 31. Wuhan Central Hospital confirmed his death on February 7 after a series of conflicting reports about his condition.

The news of his demise has sparked a public outpouring of anger and grief. Many have hailed him a martyr and a national hero for his attempts to warn the public.
