Purpose: To study the meibomian glands using infrared meibography and correlate the results with tear film parameters.
Methods: This is prospective cohort study. Two groups were included in the study: 40 eyes of healthy volunteers and 40 eyes having posterior blepharitis diagnosed on the basis of clinical examination. Tear film parameters that were studied included tear break-up time (TBUT), meibum score and superficial punctate keratopathy. They were correlated with the meibo-grade scores based on infrared meibography which can image distortion, shortening and dropout of meibomian glands.
Results: TBUT, SPK, meibum scores and meibo-grade scores were all significantly higher in the posterior blepharitis group (P = 0.02).
Conclusion: Infrared meibography is a useful tool for evaluating the meibomian glands and can augment the detection and follow-up of posterior blepharitis and related dry eye disorder for better management.
