    Abstract:
    PURPOSE: To make appropriate therapeutic decisions of intense pulsed light (IPL) for meibomian gland dysfunction (MGD) patients. METHODS: Sixty patients with MGD stage 2-3 were enrolled in IPL Group1 and Self-hygiene Group; 110 patients with MGD stage 3-4 were included in IPL + MGX Group and IPL Group2. Patients in IPL groups received IPL treatment once a month for three times. Meibomian gland expression (MGX) was combined with IPL treatment in IPL + MGX Group. Meibomian gland (MG) functions, MGD stage, associated ocular-surface indexes, and response rate were evaluated. RESULTS: Population characteristics and clinical conditions were comparable between groups. In patients with MGD stage 2-3, both IPL Group1 and Self-hygiene Group improved in MG functions, ocular surface disease index (OSDI) and tear break-up time (TBUT). No statistical difference was found in improvements. Posttreatment response rate was 64.3-66.7% in two groups. In patients with MGD stage 3-4, IPL + MGX Group achieved better improvements in MG expressibility and higher response rate (75.5%) than IPL Group2 (63.3%). Referring to IPL treatment, no statistical difference in MG functions and OSDI improvements was found among MGD patients with different ages, genders, and IPL energy exposure. Patients with higher Fitzpatrick scale improved more in MG expressibility. CONCLUSION: Self-eyelid hygiene is cost-effective for milder MGD stages. Combining MGX with IPL is necessary in more severe stages. Adult patients with all age and different genders can benefit from IPL treatment. Patients with darker skin can benefit more in expressiblity.
