Clinical Features of Lid Margin, Meibomian Gland and Tear Film Changes in Patients with Primary Pterygium

Abstract Introduction: The aim of this study was to clinically evaluate lid margin abnormality, meibomian glands expression and tear function changes in patients with primary pterygium. Methods: Fifty normal 50 pterygia participants without other ocular pathologies were randomly selected from who attended an ophthalmology visit. gland expression, break-up time, Schirmer's test results surface disease index (OSDI) evaluated. Multiple meniscus values include the lower height (TMH), depth (TMD) area (TMA) also measured using time-domain coherence tomography. Comparative analyses between groups performed for all parameters. A statistical significance level P < 0.05 considered. Association abnormality scores, time Results: Ocular index, scores significantly higher pterygium than normals (P 0.001). Tear results, TMH, TMD TMA donot differ two > 0.05). Correlation analysis demonstrated that correlated Conclusions: Primary may cause alteration expressions, which is associated discomfort. Early detection seem be important understand relationship pterygium, film functions surface.
