Loss of function of the meibomian glands among HIV and AIDS individuals undergoing antiretroviral therapy

Abstract

Background: Meibomian gland dysfunction (MGD) is one of the most encountered diseases in the clinical practice but appears to be underappreciated as it does not cause blindness. Meibomian gland dysfunction is a multifactorial and complex disorder of the ocular surface. Aim: This study aims to evaluate the characteristics of the meibomian glands in individuals living with HIV and AIDS undergoing antiretroviral therapy. Setting: The study was conducted at the antiretroviral (ARV) clinic, Mankweng Hospital. Methods: This was a prospective study conducted with 37 HIV and AIDS participants and 20 healthy controls. All participants were assessed using the Ocular Surface Diseases Index (OSDI) score and, tear break-up time and lid margin regularity (using the slit-lamp biomicroscopy). The loss of the meibomian glands was evaluated using the Marx’s line. For this study, this line represented a clinical parameter of meibomian function. Results: The OSDI score was significantly higher in the HIV and AIDS group than that of the control participants (39.95 ± 18.65 and 13.00 ± 9.09, respectively, P 0.05). The tear breakup time (TBUT) for the HIV and AIDS study group was lower than that of the control group (7.95 ± 3.54 and 9.90 ± 3.70, respectively, P 0.05). The HIV and AIDS participants showed greater meibomian gland loss relative to the healthy controls (9.30 ± 4.97 and 5.70 ± 2.1, P 0.05). Conclusion: The loss of eyelid meibomian glands is common in people living with HIV and AIDS in comparison with healthy controls. Contribution: Although there is a decrease in sight-threatening complications in the era of ARVs, ocular surface disorders (OSD) are still commonly found, which may reduce the quality of life of HIV and AIDS individuals.
