Cohort study 

研究目的:

系统观察接受全身静脉麻醉下胃肠镜检查患者术前、术后的视力、眼压变化,明确 TIVA 对患者眼底血管灌注(黄斑区 OCT - 血管成像)及神经结构(视盘 OCT、黄斑 OCT)的影响特征与短期变化规律。 分析患者年龄、基础疾病(高血压、糖尿病等)、麻醉时长、围手术期平均动脉压波动等因素,与术后眼底结构及功能指标变化的关联性,筛选影响 TIVA 后眼底指标改变的关键因素。  

Objectives of Study:

To systematically observe the changes in visual acuity and intraocular pressure before and after gastrointestinal endoscopy under total intravenous anesthesia (TIVA), and to clarify the short‑term characteristics and changing patterns of TIVA on ocular fundus vascular perfusion (macular OCT‑angiography) and neural structure (optic disc OCT, macular OCT). To analyze the correlation between factors such as patient age, underlying diseases (hypertension, diabetes mellitus, etc.), duration of anesthesia, perioperative mean arterial pressure fluctuation, and the changes in ocular fundus structural and functional indicators after surgery, and to identify the key factors affecting ocular fundus indicators after TIVA.
