Conjunctivitis

Conjunctivitis, commonly known as pink eye, is an inflammation of the thin, clear membrane that covers the white part of the eye and the eyelids (the conjunctiva). This inflammation causes the white of the eye and the inside of eyelids to become pink or red. The patient's eyes may be itchy or painful.

There are four types of conjunctivitis. These are:

1. Viral conjunctivitis. Viral conjunctivitis affects only one eye causing excessive eye watering and a light discharge from the eye.

2. Bacterial conjunctivitis. Bacterial conjunctivitis affects both eyes causing a heavy greenish discharge.

3. Allergic conjunctivitis. Allergic conjunctivitis also affects both eyes causing itching and redness and excessive tearing. The patient may also experience an itchy and red nose.

4. Giant papillary conjunctivitis. Giant papillary conjunctivitis (GPC) affects both eyes causing contact lens intolerance, itching, heavy discharge, and tearing and red bumps on the underside of the eyelids.
