研究目的:

使用广角OCTA(UWF-OCTA)量化PCV患者在抗VEGF治疗前、后玻璃体视网膜界面的变化,并分析这些变化与治疗反应的关联。  

Objectives of Study:

To quantify the changes in the vitreoretinal interface using ultra-wide-field optical coherence tomography angiography (UWF-OCTA) before and after anti-VEGF treatment in patients with polypoidal choroidal vasculopathy (PCV), and to analyze the correlation between these changes and treatment response.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.经 ICGA 确诊为 PCV 的成年(≥18 岁)的患者,性别不限;
2.患者应为初治 PCV,未接受过任何针对 PCV 的先前治疗;
3.接受抗 VEGF 治疗:患者需接受完整的抗 VEGF 治疗方案,药物为康柏西普;
4.能够完成 OCTA 和随访,患者接受广角 OCTA 成像,并承诺完成研究要求的随访期(至少6-12 个月),签署知情同意书;
5.最佳矫正视力(BCVA)20/400 至 20/40(Snellen);

Inclusion criteria

1. Adult patients (>=18 years old) with a diagnosis of polypoidal choroidal vasculopathy (PCV) confirmed by ICGA, regardless of gender. 2. Patients should be treatment-na?ve for PCV, with no prior treatment for PCV. 3. Patients will receive anti-VEGF therapy with complete regimen, using Conbercept as the therapeutic agent. 4. Patients must be able to undergo OCTA imaging and follow-up, accept wide-field OCTA imaging, agree to complete the required follow-up period (at least 6–12 months), and provide written informed consent. 5. Best-corrected visual acuity (BCVA): 20/400 to 20/40 (Snellen equivalent).

排除标准:

1.合并其他严重眼病(如糖尿病视网膜病变、视网膜静脉阻塞、葡萄膜炎等);
2.屈光间质混浊影响 OCTA 成像;
3.IOP>21mmHg;
4.患有除糖尿病、原发性高血压外可能合并眼部改变的其他全身病(如自身免疫疾病、有严重心血管事件史、神经退行性疾病);
5.固视不良或其他原因不能配合检查者;
6.长期服用可能造成眼部不良反应的药物(如避孕药);
7.其他研究者认为需要排除的情况;

Exclusion criteria:

1. Presence of other severe ocular diseases, including diabetic retinopathy, retinal vein occlusion, uveitis, etc. 2. Opacification of the refractive media precluding adequate OCTA imaging. 3.Intraocular pressure (IOP) > 21 mmHg. 4. Presence of systemic diseases other than diabetes mellitus and essential hypertension that may cause ocular alterations, such as autoimmune diseases, history of major cardiovascular events, neurodegenerative diseases. 5. Poor fixation or inability to cooperate with examinations for other reasons. 6. Long-term use of medications that may induce adverse ocular effects (e.g., oral contraceptives). 7. Any other conditions deemed exclusionary by the investigators.
