Pink Eye: Bacterial vs Viral Conjunctivitis

Conjunctivitis, commonly known as pink eye, is inflammation of the conjunctiva, the thin transparent layer covering the white part of the eye and the inner surface of the eyelids. It causes redness, discharge, and discomfort in the affected eye. Pink eye can be caused by bacteria, viruses, or allergens, and the treatment differs depending on the cause. Correctly identifying the type of conjunctivitis guides appropriate management. Viral conjunctivitis is the most common form and is often associated with upper respiratory infections caused by adenoviruses, rhinoviruses, or other viruses. It typically begins in one eye and spreads to the other, produces watery discharge, and is highly contagious. The eyelids may be slightly swollen and the eye red and irritated. Viral conjunctivitis resolves on its own without antibiotic treatment, usually within one to two weeks. Bacterial conjunctivitis is less common but distinct in its presentation. It typically produces a thicker, more purulent yellow or green discharge that causes the eyelids to stick together, particularly upon waking. It can affect one or both eyes. Common bacterial causes include Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. Treatment with topical antibiotic eye drops or ointment accelerates recovery. In newborns, conjunctivitis requires immediate medical evaluation due to the risk of gonococcal or chlamydial infection.

Allergic conjunctivitis is distinguished by itching as the predominant symptom, often with tearing and swelling of the eyelids. It occurs in both eyes simultaneously and is associated with other allergy symptoms such as sneezing and nasal congestion. It responds to antihistamine eye drops and is not infectious. Patients with conjunctivitis should avoid touching their eyes with unwashed hands, sharing towels or pillowcases, wearing contact lenses until the infection resolves, and returning to work or school while highly contagious. Most cases can be evaluated via telehealth with an appropriate visual examination.
