What is the main cause of conjunctivitis?

Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva — the thin, transparent layer of tissue that lines the inner surface of the eyelid and covers the white of the eye. It is a common eye condition, and its symptoms include red, itchy, and watery eyes.



Signs and Symptoms

The signs and symptoms of conjunctivitis can vary depending on the cause. Common signs and symptoms include a gritty feeling in the eyes, redness, burning, itching, light sensitivity, a discharge that forms a crust during the night, and a watery discharge that can cause the eyes to stick together.

Causes

The most common cause of conjunctivitis is an infection, either bacterial or viral. Other causes include allergies, irritants, and underlying medical conditions.

Risk Factors

Risk factors for conjunctivitis include:

  • age

  • contact lens use

  • contact with someone who has an eye infection

  • weakened immune system.

Prevention

To prevent conjunctivitis, it is important to practice good hygiene, such as washing your hands frequently and avoiding close contact with people who have an eye infection. It is also important to practice good contact lens hygiene, such as cleaning and replacing lenses as instructed.

Diagnosis

Your doctor will ask about your symptoms and medical history and will examine your eyes. They may also take a sample of the discharge to test for bacteria or viruses.

Treatment

Treatment for conjunctivitis depends on the cause. Bacterial conjunctivitis is usually treated with antibiotic eye drops or ointment. Viral conjunctivitis is usually treated with antiviral eyedrops. Allergy-related conjunctivitis is usually treated with antihistamine eye drops.

Coping and Support

If you have conjunctivitis, it is important to take steps to avoid spreading the infection to others. This includes washing your hands frequently and avoiding touching your eyes. It is also important to get plenty of rest and to avoid wearing contact lenses until the infection has cleared.

Complications

Complications of conjunctivitis can include impaired vision, corneal ulcers, and increased risk of developing other eye conditions.

Living with Conjunctivitis

If you have conjunctivitis, the most important thing you can do is follow the treatment plan prescribed by your doctor. Make sure to take all medications as prescribed and to follow up with your doctor if your symptoms do not improve. It is also important to practice good hygiene, such as washing your hands frequently, to help prevent the spread of the infection.
