Abstract

Purpose: This study aimed to determine the effect of intense pulsed light (IPL) treatment on meibomian gland disease.

Settings and design: This is a prospective interventional study.

Methods: Seventy eyes of patients with dry eye disease undergoing three sessions of IPL therapy, 15 days apart, were included. Each patient completed the dry eye questionnaire (SPEED) for symptomatic assessment. Dry eye evaluation tests were performed, including Schirmer's 1 test, meiboscopy, noninvasive tear break-up time (NIBUT) and interferometry. These tests were repeated before each IPL session.

Statistical analysis used: Data analysis was performed using IBM SPSS Statistics software (Version 20, Inc., Chicago, Illinois, USA). To Kolmogorov-Smirnov test was used to assess the normality of the variables. The Chi-square test was applied for statistical analysis. Level of significance was set at p ≤ 0.05.

Results: The mean symptom score from the dry eye questionnaire (SPEED) showed a significant reduction of 24.5% ( p < 0.001) in symptoms. Schirmer's 1 test showed an improvement of 16.43% on day 15 and 40.13% on day 45. Meiboscopy grade improved by 13.54% on day 45. NIBUT improved from 53.29% on day 15 to 135.53% on day 45. Interferometry showed an improvement of 58.91% on day 45.

Conclusions: The various investigative tests demonstrated both qualitative and quantitative improvements in dry eye disease, and patients reported symptomatic relief. The effects of IPL therapy, in terms of symptomatic relief, continued to improve with each session. The quality of the tear film also improved progressively. IPL therapy is a potential therapeutic option for MGD.

强脉冲光治疗后蒸发性干眼的定量和定性评价,一项前瞻性研究。
目的:探讨强脉冲光(IPL)治疗睑板腺疾病的疗效。背景和设计:这是一项前瞻性干预性研究。方法:对干眼症患者70只眼进行3次IPL治疗,间隔15天。每位患者完成干眼问卷(SPEED)进行症状评估。进行干眼评价试验,包括Schirmer's 1试验、meiboscopy、无创泪液破裂时间(NIBUT)和干眼干涉测量。这些测试在每次IPL之前重复进行。数据分析使用IBM SPSS Statistics软件(Version 20, Inc., Chicago, Illinois, USA)进行。使用Kolmogorov-Smirnov检验来评估变量的正态性。采用卡方检验进行统计分析。p≤0.05为显著性水平。结果:干眼问卷(SPEED)的平均症状评分显示症状显著降低24.5% (p < 0.001)。Schirmer's 1试验显示,第15天和第45天的改善率分别为16.43%和40.13%。第45天Meiboscopy评分提高13.54%。NIBUT从第15天的53.29%提高到第45天的135.53%。干涉测量显示第45天改善58.91%。结论:各种调查性试验显示干眼病的定性和定量改善,患者报告症状缓解。在症状缓解方面,IPL治疗的效果在每次治疗中持续改善。泪膜的质量也在逐步提高。IPL治疗是MGD的潜在治疗选择。
