A total of 300 patients were included in the study, with 150 eyes in the study group and 150 in the control group. Meibomian gland morphology was assessed by examining the tarsal plate after everting the eyelids. Tearfilm function was evaluated using tearfilm break?up time (TBUT) and Schirmer’s test (SCH I and II). Meibomian gland morphology was examined with a slit?lamp under magnification, a transilluminator using a small light emitting diode (LED) bulb, and non?contact meibography using an auto refracto?keratometer (ARK).
Results:
Females had a higher prevalence of dry eyes in our study. In all, 103 eyes (68.6%) in the study group had evaporative dry eye, making it the most prevalent type. Among the 150 controls, 104 controls with 69.3% had no dry eye symptoms, and in those with symptoms, the evaporative type was the most common, with a 28% prevalence.
