Viral Conjunctivitis

Viral conjunctivitis, also known as pink eye, is an infection of the eye caused by a virus. It is one of the most common eye infections, and is highly contagious. It is usually self-limiting, meaning it will go away on its own without treatment. However, it can cause significant discomfort and irritation.

Causes of Viral Conjunctivitis

Viral conjunctivitis is caused by a virus, usually the same virus that causes the common cold. It can also be caused by other viruses, such as herpes simplex virus, adenovirus, and enterovirus. It is spread through contact with an infected person, or through contact with contaminated objects, such as towels or washcloths.

Diagnosis of Viral Conjunctivitis

Viral conjunctivitis is usually diagnosed based on the symptoms and a physical examination of the eye. A doctor may also take a sample of the discharge from the eye to test for the presence of a virus. In some cases, a doctor may order additional tests, such as a culture or a polymerase chain reaction (PCR) test, to confirm the diagnosis.

Complications of Viral Conjunctivitis

In some cases, viral conjunctivitis can lead to complications, such as corneal ulcers, scarring, and vision loss. It can also lead to secondary bacterial infections, which can cause more serious complications. It is important to seek medical attention if the symptoms of viral conjunctivitis worsen or do not improve after a few days.

Prevention of Viral Conjunctivitis

The best way to prevent viral conjunctivitis is to practice good hygiene. This includes washing your hands often, avoiding touching your eyes, and avoiding sharing towels or washcloths. It is also important to avoid contact with people who have the infection.

Redness

The most common symptom of viral conjunctivitis is redness in the eye. This redness is caused by inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and the inner surface of the eyelids. The redness may be more pronounced in one eye than the other.

Itching and Burning

Itching and burning are also common symptoms of viral conjunctivitis. The itching may be mild or severe, and it may be accompanied by a burning sensation. The itching and burning may be worse when the eyes are exposed to light.

Tearing and Discharge

Tearing and a watery discharge are also common symptoms of viral conjunctivitis. The discharge may be clear or slightly yellowish in color. It may also be thick and sticky. The discharge may cause the eyelids to stick together, especially after sleeping.

Swollen Eyelids

Swollen eyelids are another symptom of viral conjunctivitis. The swelling may be mild or severe, and it may be accompanied by redness and itching. The swelling may be worse in the morning.

Sensitivity to Light

Sensitivity to light is another symptom of viral conjunctivitis. This sensitivity may cause the eyes to become uncomfortable or painful when exposed to bright light. It may also cause the eyes to water or tear up.

Common Causes of Viral Conjunctivitis

The most common cause of viral conjunctivitis is the adenovirus. This virus is spread through contact with an infected person or object, such as a towel or washcloth. It can also be spread through the air when an infected person sneezes or coughs. Other viruses that can cause viral conjunctivitis include herpes simplex virus, enterovirus, and mumps.

Risk Factors for Viral Conjunctivitis

Certain factors can increase the risk of developing viral conjunctivitis. These include:

• Being in close contact with someone who has the virus
• Having a weakened immune system
• Having a history of eye infections
• Living in a crowded environment
• Having a job that involves frequent contact with the public
