Conjunctivitis is the infection of the conjunctiva. The conjunctiva is a tiny layer of tissue that covers the white of the eyes and insides of the eyelids. Conjuctivitis is the most common eye condition in primary Healthcare centres.

It causes dilation of the conjunctiva blood vessels which further leads to the inflammation of the conjunctiva.

The various types of conjunctivitis are gonococcal conjunctivitis, non-gonococcal bacterial conjunctivitis, allergic conjunctivitis, viral conjunctivitis and chlamydial conjunctivitis.

There are several causes of conjunctivitis. Bacterial conjunctivitis is caused by Haemophilus influenzae, Streptococcus pneumonia and Staphylococcus aureus. Gonococcal conjunctivitis is caused by Neisseria gonorrhea and commonly found in sexually active teenagers and neonates. Viral conjunctivitis is caused by Herpes Simplex virus and Zoster virus. Irritation from chemical or foreign objects in the eyes also causes allergic conjunctivitis.

Risk factors of conjunctivitis are physical and chemical trauma, cataract surgery, refractive surgery, diabetes, immunosuppressive diseases, topical steroids, corneal abrasion, contact lenses, bacteremia, corneal infection, intravitreal injections and swimming.

Symptoms of conjunctivitis are blurred vision, sensitivity to light, eye pain, eye discharge, itching, red eye, crusted eyelids and excessive tears.

Laboratory diagnosis of conjunctivitis is done by Microscopic examination and Culture of eye swab and corneal scraping samples.
