Pink Eye

WHAT IS IT:  common eye condition causing inflammation/swelling of the conjunctiva (thin layer lining the inside of the eye and covers the white part of the eye).   It is caused by viruses, bacteria, allergens, or irritants. 

Viral:  virus caused by cold or sore throat, spreads easily but you can attend class, typically mild and clears in 7-14 days without treatment or long term effects

Bacterial:  caused by bacteria, typically mild and can last 2-3 days or up to 2-3 weeks.  Many cases improve in 2-5 days without treatment.  However, topical antibiotics can be prescribed. 

Allergic:  caused by body’s reaction to allergens (pollen from trees, plants, weeds, dust, molds, animal dander, contact lenses and solution or cosmetics).  Clears once irritant removed or treated with allergy medication.  Antihistamine eye drops or pills can alleviate symptoms.

Treatment is dependent upon cause of conjunctivitis. It is most commonly mild and will resolve on own WITHOUT treatment.  However, many times treatment may be necessary. Discontinue contact lens use during treatment and replace contacts after symptoms resolve. Wash your hands often and avoid touching eyes. Symptoms can be soothed by applying a warm or cool compress to closed eyes. Lubricant eye drops can increase comfort
