Meibomian gland dysfunction (MGD) is considered a key pathogenic factor in the development of dry eye syndrome (DES). The aim of this study was to assess the anatomical and functional state of the meibomian glands in military personnel with symptoms of DES using the LacryDiag diagnostic system. Materials and Methods. A total of 120 military personnel (240 eyes) with complaints of DES symptoms were examined. Two control groups were formed: individuals with DES symptoms not serving in the military (n=40), and healthy participants (n=40). The study utilized meibography methods, visualization with LacryDiag, and calculation of the meibomian gland dysfunction index (MGDI). Gland density analysis was performed using the ImageJ software. Results. In the group of military personnel, the average meibomian gland density was 28.6%, corresponding to moderate atrophy. In control group 1, the value reached 51.4%, and in control group 2 — over 70%. The average MGDI value in the main group was 1.58±0.34 points, compared to 1.22±0.22 and 0.48±0.11 in the respective control groups (p<0.05). A strong positive correlation was established between the OSDI index and MGDI in military personnel (r=0.701). Conclusion. Military personnel demonstrate more pronounced meibomian gland dysfunction than civilian individuals, which confirms the need for in-depth diagnosis and prevention of DES using high-precision methods such as LacryDiag.
