PURPOSE: We investigated the subjective and objective outcome after intense pulsed light (IPL) treatment and meibomian gland expression on the upper and lower eyelids compared with those after IPL treatment on the lower eyelid alone in patients with moderate-to-severe meibomian gland dysfunction (MGD).
METHODS: Patients who underwent four IPL treatment sessions with meibomian gland expression were divided into upper and lower treatment group and conventional treatment group treated with lower eyelid alone. All patients underwent an ophthalmologic examination and answered a symptom questionnaire before the first treatment and 1 month after the last treatment. An ophthalmologic examination included tear break-up time (TBUT), fluorescein staining score, Schirmer's test, matrix metalloproteinase-9 (MMP-9), meibum grade, color, consistency, and lid margin telangiectasia. Additionally, visual acuity and adverse effects were checked on every visit.
RESULTS: Of 115 patients, 75 in the upper and lower treatment group and 40 in the conventional treatment group were included. TBUT, fluorescein staining score, subjective symptom, and meibum grade were significantly improved in both groups. Additionally, meibum color and consistency of upper and lower eyelids significantly decreased post-treatment in both groups. The lid margin telangiectasia of the upper and lower eyelids significantly decreased post-treatment in the upper and lower treatment group. MMP-9 positivity and grading scores significantly decreased post-treatment in both groups, and no severe adverse effects occurred during the follow-up period.
CONCLUSION: Additional IPL treatment on the upper eyelid using a protective device was proven safe and provided an additive improvement in treating moderate-to-severe MGD.
