How do you diagnose giant papillary conjunctivitis?

• A. Slit lamp exam with fluorescein only after corneal staining
• B. Lid eversion with NaFl (essential for early diagnosis)
• C. Tear osmolarity testing
• D. Fundus exam

Answer: (B)

Giant papillary conjunctivitis is identified by looking for the large, cobblestone-like papillae on the upper tarsal conjunctiva. The key step is everting the upper eyelid so you can directly visualize the palpebral surface where these papillae form. Fluorescein staining is helpful to check the corneal surface for any accompanying epithelial defects, but the telltale sign of GPC lies in the lid’s inner surface. By exposing the upper lid, you can detect the papillary reaction early, especially in contact lens wearers or people with chronic irritation. Slit-lamp exam with fluorescein after corneal staining may miss the lid changes if the lid isn’t opened and inspected. Tear osmolarity testing and a fundus exam don’t address the characteristic conjunctival changes of GPC and are not diagnostic for this condition.
