研究目的: |
(1)联合 CNN 及 Transformer 算法像素级分割MNV 的三维血管结构,量化MNV立体形态学特征; (2)从时间维度解析 nAMD-MNV 在抗VEGF治疗过程中,新生血管三维结构的重塑规律,揭示抗VEGF治疗MNV的形态学机制; (3)利用双向长短时记忆神经网络 BiLSTM 算法,构建融合 MNV 三维结构动态演变的疾病活动性监测模型。 |
||||||||||||||||||||||
|
Objectives of Study: |
(1) Combined CNN and Transformer algorithms were used to segment the 3D vascular structure of MNV at the pixel level and quantify the three-dimensional morphological features of MNV. (2) The remodeling patterns of the 3D structure of new blood vessels in nAMD-MNV during anti-VEGF treatment were analyzed from the temporal dimension to reveal the morphological mechanism of anti-VEGF treatment of MNV. (3) A bidirectional long short-term memory (BiLSTM) neural network algorithm was used to construct a disease activity monitoring model that integrates the dynamic evolution of the 3D structure of MNV. |

|
Inclusion criteria |
1. According to the "Guidelines for the Clinical Diagnosis and Treatment of Age-Related Macular Degeneration in China (2023)", patients diagnosed with wet age-related macular degeneration by combining OCT, OCTA, FFA, ICGA and other ophthalmological examinations; 2. Accept the standard "3+PRN" anti-VEGF treatment regimen and be willing to cooperate with follow-up; 3. Patients should not have received any history of anti-VEGF drug injection, intraocular laser treatment or intraocular surgery within 3 months before baseline; 4. Obtain informed consent from the patient and sign the informed consent form. |

|
排除标准: |
1.存在其他影响视觉功能或眼底成像的疾病,如黄斑水肿、黄斑劈裂、黄斑裂孔、青光眼、缺血性视神经病变、角膜病变、眼外伤等; 2.两种或两种以上黄斑病变共存的患眼; 3.屈光间质浑浊或黄斑区出血过于浓厚、视黄斑区严重萎缩等原因影响SS-OCTA图像质量导致难以分析; 4.服用已知会引起视网膜毒性的药物,如羟氯喹等,或有放射线暴露史等特殊既往史及个人史; 5.不能完成随访观察致相关资料不全。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. The presence of other diseases that affect visual function or fundus imaging, such as macular edema, macular schisis, macular hole, glaucoma, ischemic optic neuropathy, corneal lesions, ocular trauma, etc. 2. Eyes with two or more coexisting macular degeneration; 3. Turbidity of the refractive media, excessive macular hemorrhage, severe atrophy of the retinal area, etc. affect the quality of SS-OCTA images, making them difficult to analyze; 4. Taking drugs known to cause retinal toxicity, such as hydroxychloroquine, or having a special past history or personal history of radiation exposure; 5. Failure to complete follow-up observations resulted in incomplete relevant data. |
