研究目的: |
确定短期应用恒格列净对糖尿病 CKD中OCT-A参数(中央凹无血管区(FAZ)大小、血管密度和灌注密度)的影响。明确恒格列净对FAZ的影响,探究恒格列净是否能减少FAZ扩大(提示改善视网膜缺血)或改善FAZ形态(反映微血管修复)。 |

|
Objectives of Study: |
To determine the short-term effects of henagliflozin on OCT-A parameters (foveal avascular zone [FAZ] area, vessel density, and perfusion density) in patients with diabetic chronic kidney disease (CKD). Specifically, to clarify henagliflozin's impact on FAZ morphology, investigating whether it reduces FAZ enlargement (suggestive of improved retinal ischemia) or promotes FAZ remodeling (indicating microvascular repair). |
