背景和目的：扫描源光学相干断层扫描血管造影（SS-OCTA）和不同的边界特异性分割策略被用来区分1型黄斑新生血管（MNV）从2型MNV的眼睛渗出性年龄相关性黄斑变性（AMD）。患者和方法：眼睛渗出性AMD被纳入一项前瞻性研究。分割策略包括：对于整个MNV，从外视网膜（OR）到脉络膜毛细血管（CC）的厚片，对于1型MNV，从视网膜色素上皮（RPE）到CC的厚片，以及来自的厚片。结果：在13只眼中，使用不同分割策略的SS-OC-TA B扫描和正面图像能够识别MNV的1型和2型成分。结论：在渗出性AMD患者中，使用SS-OCTA成像和商业上可获得的边界特异性分割策略来区分1型和2型MNV。
BACKGROUND AND OBJECTIVE: Swept-source optical coherence tomography angiography (SS-OCTA) and different boundary-specific segmentation strategies were used to distinguish type 1 macular neovascularization (MNV) from type 2 MNV in eyes with exudative age-related macular degeneration (AMD).PATIENTS AND METHODS: Eyes with exudative AMD were enrolled in a prospective study. Segmentation strategies included a slab from the outer retina (OR) to the choriocapillaris (CC) for the entire MNV, a slab from the retinal pigment epithelium (RPE) to the CC for the type 1 MNV, and a slab from the. OR to the RPE for the type 2 MNV.RESULTS: In 13 eyes, SS-OC-TA B-scans and en face images using different segmentation strategies were able to identify type 1 and type 2 components of the MNV.CONCLUSION: In eyes with exudative AMD, SS-OCTA imaging and commercially available boundary-specific segmentation strategies were used to distinguish between type 1 and type 2 MNV.
