This study evaluates the effect of intense pulsed-light (IPL) treatment in patients with meibomian gland dysfunction (MGD) using a novel dual-band filter (vascular filter, 530-650 nm and 900-1200 nm) and compares it with the effect and discomfort during treatment using a conventional filter.
The medical records of 89 patients (89 eyes) with MGD who underwent IPL treatment were reviewed. Patients treated with the vascular filter or conventional 590 nm filter were designated as Group A or Group B, respectively. Patients underwent IPL treatment four times every four weeks. Ocular surface disease index (OSDI) scores, dry eye (DE), and MGD parameters were determined before the first IPL treatment and after the fourth IPL treatment. Visual analog scale (VAS) scores were obtained at every IPL treatment. OSDI, DE and MGD parameters, and VAS were compared between the groups.
OSDI, DE, and MGD parameters improved after the four IPL treatments in both groups. There were no significant differences, between the groups, in OSDI, DE, and MGD parameters, before the first IPL treatment and after the fourth IPL treatment. VAS at each of the IPL treatments was lower in Group B than in Group A.
IPL treatment using the novel vascular filter for patients with MGD is effective compared with conventional IPL treatment for MGD patients.
本研究使用一种新型双波段滤光片（血管滤光片，530 - 650纳米和900 - 1200纳米）评估强脉冲光（IPL）治疗睑板腺功能障碍（MGD）患者的效果，并将其与使用传统滤光片治疗期间的效果和不适感进行比较。
回顾了89例接受IPL治疗的MGD患者（89只眼）的病历。分别将接受血管滤光片或传统590纳米滤光片治疗的患者指定为A组或B组。患者每四周接受4次IPL治疗。在首次IPL治疗前和第四次IPL治疗后测定眼表疾病指数（OSDI）评分、干眼（DE）和MGD参数。每次IPL治疗时获得视觉模拟量表（VAS）评分。比较两组之间的OSDI、DE和MGD参数以及VAS。
两组在4次IPL治疗后OSDI、DE和MGD参数均有所改善。在首次IPL治疗前和第四次IPL治疗后，两组之间的OSDI、DE和MGD参数无显著差异。B组每次IPL治疗时的VAS低于A组。
与传统IPL治疗MGD患者相比，使用新型血管滤光片对MGD患者进行IPL治疗是有效的。
