Core Tip
Core Tip: Giant papillary conjunctivitis may develop after Ahmed glaucoma valve implantation even when the tube and pericardial patch graft remain fully covered and unexposed. In this patient, postoperative itching, redness, and mucous discharge were caused by superior tarsal giant papillae rather than infection or device failure. Routine upper lid eversion is essential in symptomatic patients, because early recognition allows successful medical treatment and preservation of implant function.
