Comparison of the therapeutic effect of Meibomian Thermal Pulsation LipiFlow® on obstructive and hyposecretory meibomian gland dysfunction patients.

To explore the effect of Meibomian Thermal Pulsation LipiFlow® on obstructive and hyposecretory meibomian gland dysfunction. Twenty-five subjects diagnosed with obstructive meibomian gland dysfunction (OMGD) and another 25 hyposecretory meibomian gland dysfunction (HMGD) patients were collected receiving the unilateral treatment with LipiFlow®. We evaluated the parameters variables including Standard Patient Evaluation of Eye Dryness (SPEED), Ocular Surface Disease Index (OSDI), Schirmer I test (SIT), noninvasive keratographic breakup time (NIKBUT), tear meniscus height (TMH), and lipid layer thickness (LLT), partial blink rate (PBR), meibomian gland loss, meibomian gland morphology with LipiView®. Meibomian gland expressibility and secretion quality were evaluated for OMGD subjects. All the results were recorded pre-therapy and 4 weeks, 8 weeks, 12 weeks post-therapy. SPEED, OSDI, and PB decreased, meanwhile, NIKBUT, TMH, SIT, and LLT increased compared with baseline in both groups after treatment (P < 0.001), whereas the magnitude of the improvement in the OMGD group was greater than that in the HMGD group (P < 0.001). There was no significant posttreatment structural meibomian gland change in both groups. The meibomian gland expressibility and secretion quality score increased after treatment in the OMGD group (P < 0.001). The Meibomian Thermal Pulsation LipiFlow® is effective for both obstructive and hyposecretory meibomian gland dysfunction and the therapeutic effect on obstructive meibomian gland dysfunction is greater than that on hyposecretory meibomian gland dysfunction.
