Objective: To examine lymphatic microvessel density (LMVD) in primary pterygia. Methods: We included tissue samples from 88 excised primary (including 34 grade 1, 28 grade 2, and 26 grade 3) pterygia and from 7 nasal epibulbar conjunctivae segments used as control samples. Sections from each pterygium were immunostained with CD31 and lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) monoclonal antibodies to evaluate LMVD and blood microvessel density. We used real-time polymerase

Results: A small number of CD31-positive LYVE-1negative blood vessels and only a few CD31-and LYVE-1-positive lymphatic vessels were detected in the nor-
