GPC is most commonly linked to wear of which type of contact lens?

• A. Silicone hydrogel
• B. Rigid gas permeable
• C. Daily wear soft lenses
• D. Hard contact lenses

Answer: (A)

Giant papillary conjunctivitis is a reaction of the upper eyelid conjunctiva to chronic mechanical irritation and deposits from contact lenses. It occurs most often with soft lenses worn for extended periods, because the lens remains in contact with the conjunctiva longer and can accumulate deposits that stimulate papillary growth. Silicone hydrogel lenses are a common soft lens material used for extended wear, so they are the type most frequently linked to GPC. Rigid gas permeable and hard lenses are firmer and interact less with the lid conjunctiva in a way that promotes this papillary response, and daily wear soft lenses, while capable of causing it, are less strongly associated than extended-wear silicone hydrogels.
