Conjunctivitis Pink Eye

About Conjunctivitis Pink Eye

Conjunctivitis, commonly called pink eye, is inflammation of the conjunctiva, the thin transparent tissue covering the white of the eye and inner eyelid. It affects millions worldwide annually. Types include viral most common, approximately 80 percent, bacterial, allergic, and irritant chemical. Viral conjunctivitis, usually caused by adenoviruses, produces watery discharge, redness, itching, and foreign body sensation. It is highly contagious, spreading through direct contact, and typically starts in one eye before spreading to the other. Bacterial conjunctivitis produces thick, yellow green purulent discharge, often causing the eyelids to stick together, particularly in the morning. Common bacteria include Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. Allergic conjunctivitis produces intense itching, watery discharge, and occurs in both eyes simultaneously, associated with other allergy symptoms. Treatment depends on the type. Viral conjunctivitis is self limiting, resolving in 7 to 14 days. Cold compresses and artificial tears provide symptomatic relief. Bacterial conjunctivitis often settles on its own, although antibiotic drops such as ofloxacin, polymyxin trimethoprim, or azithromycin may be prescribed. Allergic conjunctivitis responds to antihistamine drops olopatadine, ketotifen and allergy medications. Hand hygiene reduces spread of viral and bacterial forms. Eye pain, marked light sensitivity, or changes in vision with a red eye need urgent medical assessment.
