Comparative Analysis of Intense Pulsed Light Therapy in Patients with Meibomian Gland Dysfunction, with and Without Glaucoma Medication.

: This study assessed the efficacy of intense pulsed light (IPL) therapy for treating meibomian gland dysfunction (MGD), a key contributor to evaporative dry eye disease (DED), by comparing outcomes in patients with idiopathic MGD versus those with MGD induced by glaucoma medications. : In a retrospective analysis of 45 patients, divided into groups based on glaucoma medication use (20 patients) and non-use (25 patients), all underwent four IPL sessions combined with meibomian gland expression (MGX) at 3-week intervals. Key metrics evaluated included Ocular Surface Disease Index (OSDI) scores, tear breakup time (TBUT), Schirmer I test scores, and meibography scores, pre- and post-treatment. : Significant improvements were observed in both groups across all parameters post-treatment, indicating enhanced tear film stability and meibomian gland function. The non-glaucoma group showed slightly greater improvements, suggesting the potential impact of glaucoma medications on MGD management. : These findings underscore IPL therapy's effectiveness in improving DED symptoms and meibomian gland function, highlighting its utility as a treatment option for patients with MGD, including those on glaucoma medications.
