研究设计:

巢式病例-对照研究 

Study design:

Nested case-control study 

研究目的:

(1)基于巢式病例对照研究的代谢组学测序检测发现与青光眼滤过术后结膜下瘢痕化相关生物标志物。 (2)前瞻观察性研究验证术前代谢标记物对青光眼滤过术后结膜下瘢痕化预测作用。 (3)探索代谢标记物致HTFs纤维化机制,并验证靶向干预对兔眼青光眼滤过术后抗瘢痕化作用。  

Objectives of Study:

(1) Identification of biomarkers associated with subconjunctival scarring after glaucoma filtration surgery through metabolomic sequencing in a nested case-control study. (2) A prospective observational study to validate the predictive value of preoperative metabolic markers for subconjunctival scarring after glaucoma filtration surgery. (3) Investigation of the mechanism by which metabolic markers induce HTF (human trabecular fibroblast) fibrosis, and evaluation of the anti-scarring effect of targeted interventions in a rabbit model of glaucoma filtration surgery.
