研究疾病:

干眼症;2020年发表的《中国干眼专家共识》指出干眼是一种多因素引起的慢性眼表疾病,是由泪液的质、量及动力学异常导致的泪膜不稳定或眼表微环境失衡,造成眼部干涩、异物感、烧灼感、刺痛、畏光等多种不适症状,可伴随眼表炎症、组织损伤及神经异常。  

Target disease:

Dry eye syndrome; The "Chinese Expert Consensus on Dry Eye" published in 2020 states that dry eye is a chronic ocular surface disease caused by multiple factors. It is triggered by abnormal quality, quantity, and dynamics of tears, resulting in unstable tear film or imbalance of the ocular surface microenvironment, causing various discomfort symptoms such as dryness, foreign body sensation, burnin

研究目的:

主要研究目的 利用SS-OCTA量化评估MGD患者在OPT治疗前后睑缘血管血流信号(VD)的变化(ΔVD),建立可重复、可量化的影像学终点用于OPT疗效评价。 次要研究目的 1.分析OPT治疗前后睑缘血流密度等影像学指标与症状(OSDI)及眼表体征(TBUT、角膜荧光素染色、睑板腺缺失、睑脂质量、腺口开放等)的相关性。 2.进行分组探索:按基线睑缘血管分级或MGD严重度分层比较不同程度患者对治疗反应的差异,从而指导优化OPT方案。  

Objectives of Study:

Primary ObjectiveTo quantitatively evaluate changes in eyelid margin vascular flow signals (vessel density, VD) in patients with meibomian gland dysfunction (MGD) before and after optimal pulse technology (OPT) treatment using swept-source optical coherence tomography angiography (SS-OCTA), and to establish a reproducible and quantifiable imaging endpoint for assessing the therapeutic efficacy of OPT. Secondary Objectives: 1.To analyze the correlations between imaging parameters—such as eyelid margin vessel density—before and after OPT treatment and clinical symptoms (Ocular Surface Disease Index, OSDI) as well as ocular surface signs, including tear break-up time (TBUT), corneal fluorescein staining, meibomian gland dropout, meibum quality, gland orifice patency, and related parameters.2.To conduct subgroup analyses by stratifying patients according to baseline eyelid margin vascular grading or the severity of MGD, and to compare differences in treatment responses among patients with varying degrees of disease severity, thereby providing guidance for optimizing OPT treatment protocols.

2.Contact lens wear within the preceding 2 weeks;
3.Recent use of systemic or topical medications that may significantly influence eyelid margin congestion or inflammation and cannot be discontinued, or planned changes in dry eye–related treatment regimens during the study period;
4.Pregnancy or lactation;
5.Photosensitivity or the presence of skin or systemic conditions unsuitable for OPT treatment, including but not limited to photosensitive dermatoses, active cutaneous malignancies, or recent excessive sun exposure or tanning;
6.nability to cooperate with examinations or inadequate SS-OCTA image quality, defined as an intra-session vessel density variation greater than 10%;
