AIM- To evaluate the meibomian gland structure, function and tear film stability in patients with pterygium and to assess the relationship between the variables
METHOD- 50 pterygium patients and 40 controls were enrolled in the study for 1 yr. Ocular surface disease index (OSDI), meibomian gland expression score, lipid secretion of meibomian gland, meiboscore, lid margin abnormality score, Tear film breakup time, schirmer1, tear meniscus and pictures of each patient were performed.
RESULTS- The OSDI and meibomian gland function scores were significantly higher in pterygium group than control group (both p<0.05). No difference in tear volume and lid margin scores between the two groups was recorded(p>0.05). Besided most parameters of meibomian gland dysfunction and TBUT were significantly correlated with dry eye index in pterygium (p<0.05). CONCLUSION- MGD may play a critical role in the development of tear film instability which may be the missing link between dry eye and pterygium.
