Conjunctival Autofluorescence and Cytological Changes in Pterygium

Purpose: The purpose of this study was to evaluate the presence and pattern of autofluorescence and its related cytological changes in pterygium. Methods: Eighty-six patients with unilateral pterygium and 76 controls were recruited. We graded pterygium, looked for autofluorescence, performed cytology of the nasal conjunctiva, repeated evaluation after 6 months, compared findings with controls, and assessed the progression of pterygium from photographs with the help of ImageJ software. Results: Autofluorescence was present in 51% of cases with pterygium. Autofluorescence at the leading edge (65.9%) was the predominant pattern seen. In total, 83.3% of grade 3 pterygia, 64.7% of grade 2 pterygia, and 28.9% of grade 1 pterygia (P value
