Which lens material is most commonly linked to GPC?

Which lens material is most commonly linked to GPC?

• A. Silicone hydrogel
• B. Rigid gas permeable
• C. Daily wear glass
• D. Conventional hydrogel

Answer: (A)

Giant papillary conjunctivitis happens when the upper eyelid’s conjunctiva reacts to chronic irritation and surface deposits on a contact lens. Silicone hydrogel lenses are the most commonly linked to GPC because, while they offer high oxygen permeability, they can accumulate tear-film deposits—lipids and proteins—on the lens surface. Extended wear and improper hygiene increase lens–eye time and interaction with the lid margin, promoting papillary hypertrophy in the upper lid. So, despite their breathable nature, these lenses are the type most often associated with the inflammatory papillary response seen in GPC.
