    Abstract:
    BACKGROUND: To evaluate the effects on ocular surface signs and symptoms of serial sessions of heating and vibrating eye mask followed by intense pulsed light (IPL) therapy for the treatment of dry eye disease owing to meibomian gland dysfunction (MGD). METHODS: Consecutive patients with MGD whose signs and symptoms were not satisfactorily controlled with conventional therapy were included. Patients received 3 treatments performed at day 1, 15, and 45 incorporating a session with a newly-developed eye mask (Activa, SBS Sistemi, Turin, Italy) immediately followed by IPL therapy (E > Eye device, E-Swin, Paris, France). Patients were examined before the first session (T0) and 30 days after the last session (T1) for the measurement of: noninvasive break-up time (NIBUT); lipid layer thickness (LLT); tear meniscus height (TMH); meibomian gland loss (MGL); tear osmolarity. Ocular discomfort symptoms were ascertained by ocular surface disease index (OSDI) questionnaire. RESULTS: Thirty patients were ultimately included in the study. At T1, all objective ocular surface parameters improved significantly, except for TMH: NIBUT and LLT increased from 6.4 ± 1.7 to 8.6 ± 1.7 s and from 57.7 ± 15.5 to 81.3 ± 12.0 μm (all P < 0.001), while MGL and tear osmolarity decreased from 21.1 ± 17.3 to 17.0 ± 14.1% and from 302.0 ± 8.5 to 295.7 ± 6.9 mOsm/L (respectively, P = 0.004 and P < 0.001). In parallel, OSDI score decreased significantly from 49.8 ± 13.5 to 29.8 ± 10.6 (P < 0.001). In the historical control group of patients who underwent only IPL, NIBUT, LLT, tear osmolarity and OSDI improved significantly but not MGL and TMH. CONCLUSIONS: Serial sessions incorporating the application of an eye mask producing heating and vibration immediately followed by IPL therapy are able to improve all ocular surface parameters as well as ocular discomfort symptoms in MGD patients.
