研究目的: |
评估wAMD 患眼在接受抗VEGF治疗后,OCTA测量的CNV血流参数(如血流面积、血管密度)以及OCT测量的解剖结构参数(如CMT、SRF、IRF)的纵向变化。 |
||||||||||||||||||||||
|
Objectives of Study: |
Assess the longitudinal changes in CNV blood flow parameters measured by OCTA (e.g., flow area, vessel density) and anatomical structural parameters measured by OCT (e.g., central macular thickness [CMT], subretinal fluid [SRF], intraretinal fluid [IRF]) in eyes of patients with wAMD after anti-VEGF treatment. |

Inclusion criteria |
1. wAMD group: (1) Diagnosed clearly: Confirmed as active wet age-related macular degeneration (wAMD) through fundus examination, OCT, OCTA and/or fluorescein fundus angiography (FFA), with the presence of choroidal neovascularization (CNV). (2) Initial treatment: At the time of diagnosis, it was the first treated eye, meaning no previous treatment for wAMD (including anti-VEGF, PDT, laser, etc.) had been received. (3) Age: 18 - 80 years old. (4) Treatment plan: Had received standard anti-VEGF treatment (such as ranibizumab, conbercept, aflibercept, etc.) and completed at least 3 "loading dose" injections. (5) Data completeness (core): Baseline (within 1 week before treatment): Has complete and high-quality BCVA (best corrected vision), IOP (intraocular pressure), OCT and OCTA examination records. Follow-up (e.g., 1 month after the loading dose): Has complete and high-quality BCVA, IOP, OCT and OCTA examination records. Image quality: All OCT and OCTA images used for analysis have good quality, without obvious motion artifacts, occlusion or slices, and can clearly distinguish the structures of the retina and the morphology of CNV. 2. Control group: (1) Age-matched: Age 18 - 80 years old, and matched with the age distribution of the study group. (2) Eye health: Normal fundus examination, or only a few small hard nuclear opacities. (3) BCVA >= 0.8, IOP <= 21 mmHg, no history of glaucoma or evidence of optic nerve damage. (4) Data completeness: Has complete and high-quality OCT and OCTA examination records. (5) General condition: No known systemic diseases that affect retinal microcirculation (such as diabetes, uncontrolled hypertension). |
