What should you know about GPC conjunctivitis?

GPC means giant papillary conjunctivitis. It affects the inner surface of the upper eyelid, where irritation can produce raised bumps and excess mucus. Contact lenses, deposits on lenses, or an ocular prosthesis may contribute. Symptoms can include intense itching, stringy eye discharge, blurred vision that clears with blinking, and difficulty wearing lenses. GPC is different from a simple bacterial infection, so the appearance and history matter when choosing care.

Stop wearing contact lenses while symptoms are active and seek advice about cleaning, replacement, or a temporary change in lens type. Avoid rubbing the eyes, wash hands before touching them, and use a clean cold compress for comfort. Do not share towels or eye products. A GP consultation can help assess the eye and arrange referral if the diagnosis is uncertain or symptoms continue.

Get prompt medical advice for eye pain, light sensitivity, worsening redness, a noticeable change in vision, or symptoms after an eye injury. These features can indicate a problem involving the cornea rather than uncomplicated conjunctivitis. Seek urgent care if vision is significantly reduced, pain is severe, or the eye is very swollen. Eye discharge and red eye can have several causes and should be assessed when persistent.

Ask whether contact lenses are contributing, how long to avoid them, how to clean or replace the lenses and case, whether allergy treatment is relevant, and what symptoms should trigger an eye review.
