Pink Eye (Conjunctivitis): Overview
Pink eye (conjunctivitis) is an inflammation or infection of the clear membrane that covers the eye (the conjunctiva). The pink or red color is caused by blood vessels in the eye that are inflamed.
There are four common types of pink eye (conjunctivitis):
 |
Viral conjunctivitis |

Bacterial conjunctivitis |

Allergic conjunctivitis |
|
Giant papillary conjunctivitis |
Viral conjunctivitis is the most common type of pink eye. It usually causes a watery discharge and can affect both eyes.
Bacterial conjunctivitis typically affects both eyes and causes a thick yellow or greenish discharge.
Allergic conjunctivitis affects both eyes and causes itchy, red or watery eyes.
Giant papillary conjunctivitis usually affects both eyes and causes itching, heavy discharge and red bumps on the underside of the eyelids.

Pink Eye (Conjunctivitis): Treatment
Pink eye is treated in different ways, depending on the type.
Bacterial conjunctivitis is usually treated with prescription antibiotic eye drops that improve symptoms within one or two days.
Viral conjunctivitis will eventually go away without treatment. The symptoms can be relieved with an over-the-counter (OTC) eye drop if necessary.
Allergic conjunctivitis symptoms are usually relieved with OTC or prescription medications including antihistamines, decongestants, mast cell stabilizers, steroids and anti-inflammatory drops.
Always consult your healthcare professional for proper diagnosis and treatment of conjunctivitis.
