Which symptom is commonly seen in giant papillary conjunctivitis before signs appear?

• A. Itching following lens removal
• B. Red eye during wear
• C. Blurred vision on waking
• D. Tearing only

Answer: (A)

The key idea is that itching is the earliest subjective symptom in giant papillary conjunctivitis for contact lens wearers. This itchy, irritated feeling after removing the lens signals an allergic-inflammatory response to lens-related proteins and deposits, which can occur before visible changes are seen on examination. As the reaction persists, the palpebral conjunctiva develops the characteristic large papillae and other signs such as redness and mucous discharge. The other symptoms—redness during wear, blurred vision on waking, or tearing alone—are more nonspecific and typically arise after the condition has progressed, so they don’t best identify GPC before signs appear.
