Abstract

Purpose
To evaluate the therapeutic effect of intense pulsed light (IPL) therapy for the treatment of dry eye with meibomian gland dysfunction (MGD).
Methods
A retrospective study was conducted for 124 eyes of 62 patients with dry eye with MGD who underwent 3 IPL sessions at 3 week intervals. All patients underwent clinical examination before and during treatment as well as 3 weeks after the last treatment. Measured parameters include Meibomian gland expressibility (MGE), Meibomian gland secretion (MGS) score, tear meniscus height (TMH), noninvasive break-time (NIBUT), corneal staining score (Oxford scale), Ocular Surface Diseases Index (OSDI), and subjective ocular discomfort improvement.
Results
Meibomian gland function (MGE, MGS), ocular surface parameters (NIBUT, Oxford scale) and dry eye symptom (OSDI, subjective ocular discomfort improvement) of patients were significantly improved from baseline to after the 1st IPL, and the 3rd IPL weeks (p < 0.05 for all). However, no significant difference in TMH was observed.
Conclusions
This study showed that IPL was a useful and effective treatment in patients of dry eye with MGD to stabilizes the tear film and improve meibomian gland function and ocular symptoms.
