Conjunctivitis (Pink Eye)

Overview

Conjunctivitis is very common. It can be caused by infection or allergy. Infective conjunctivitis spreads easily but usually clears up on its own.

Symptoms

• Red or pink eye
• Watery or sticky discharge
• Itching, burning or a gritty feeling
• Crusting of the eyelids, especially in the morning

Causes and risk factors

Causes include viruses, bacteria, allergies such as pollen or dust, and irritants like smoke or chlorine.

Diagnosis

A doctor usually diagnoses it from the symptoms and an eye examination.

Treatment

Viral conjunctivitis improves on its own. Bacterial conjunctivitis may need antibiotic drops. Allergic conjunctivitis is treated with anti-allergy drops. Good hand hygiene and not sharing towels prevent spread.

When to see a doctor

See a doctor if symptoms do not improve in a few days, or for any eye infection in a newborn. Seek urgent care for eye pain, sensitivity to light or changes in vision.
