Abstract
Meibomian gland dysfunction (MGD) is the leading cause of dry eye syndrome. It is a frequent and underdiagnosed condition with a significant socioeconomic impact. We propose here the evaluation of a platform combining intense pulsed light and photo-biomodulation in the treatment of Meibomian gland dysfunction. We conducted a retrospective study at Brest University Hospital analyzing a cohort of 74 eyes (37 patients) at 1month and 3months after a protocol of 3 Eye-Light® (Espansione Group, Italy) sessions 14days apart between January2019 and April2020. The primary outcome was the change in OSDI quality of life score. Secondary outcomes were the SPEED questionnaire score; tear break-up time (BUT), Oxford score, non-invasive break-up time (NIBUT), lipid layer thickness, lacrimal meniscus height and Meibomian gland atrophy rate. Tolerance of the treatment was also evaluated. We found a significant improvement in OSDI scores at 1month (-17.32; 95% CI (-25.84; -8.79), P<0.0001) and 3months (-16.95; 95% CI (-25.26; -8.64), P<0.0001). The SPEED score, BUT, Oxford score, Meibomian gland atrophy and NIBUT were also statistically significantly improved. Tolerance to treatment was very good despite two cases of herpetic keratitis, which resolved on treatment. Treatment with the Eye-Light® in three sessions every two weeks significantly reduced symptoms and ocular surface damage in patients with MGD. This data suggests that the use of Eye-Light® may represent a good option for patients with MGD.
