Purpose To demonstrate the marginal corneal vascular remodelling using optical coherence tomography angiography (OCTA) after pterygium surgery. Methods Twenty-two eyes of 19 patients (8 males, 11 females; age, 58.68 ± 0.34 years) with primary grade-T3 nasal pterygium were enroled in this study. The eyes underwent excision of the pterygium followed by a free limbal-conjunctival autograft. OCTA was performed in the nasal limbal area before surgery and at 10 days, 1 month, and 3 months after surgery. The scans were analyzed in terms of postoperative vascular remodelling of the autograft and marginal corneal vascular arcades (MCAs). Results Preoperatively, the pterygium presented as abnormal centripetal vascular growth in OCTA scans. The conjunctival vessel density in the nasal quadrant was 29.26% ± 1.00%, 15.80% ± 0.83%, 19.80% ± 0.88%, and 20.26% ± 0.89% before and 10 days, 1 month, and 3 months, respectively, after surgery ( F = 1.55, P < 0.01). The vessel density of MCAs was 28.33% ± 0.88%, 42.09% ± 0.41%, and 42.46% ± 0.31% 10 days, 1 month, and 3 months, respectively, after surgery ( F = 188.2, P < 0.01). Conclusions We describe a new application of OCTA for MCA vasculature imaging. Vascular remodelling of the graft and MCAs appeared at 1 month and continued for 3 months after surgery.

光学相干断层扫描血管造影术用于自体角膜缘结膜移植翼状胬肉手术后角膜边缘血管重塑

目的 使用光学相干断层扫描血管造影术 (OCTA) 展示翼状胬肉手术后角膜边缘血管重塑。方法 原发性T3级鼻翼胬肉患者19例(男8例,女11例;年龄58.68±0.34岁)22眼纳入研究。眼睛接受翼状胬肉的切除,随后进行游离的角膜缘结膜自体移植。OCTA 在手术前和手术后 10 天、1 个月和 3 个月在鼻缘区域进行。根据自体移植物和边缘角膜血管弓 (MCA) 的术后血管重塑分析扫描结果。结果 术前 OCTA 扫描显示翼状胬肉异常向心性血管生长。鼻象限结膜血管密度为 29.26%±1.00%、15.80%±0.83%、19.80%±0.88% 和 20。术前和术后 10 天、1 个月和 3 个月分别为 26% ± 0.89% ( F = 1.55, P < 0.01)。术后 10 天、1 个月和 3 个月 MCA 的血管密度分别为 28.33%±0.88%、42.09%±0.41% 和 42.46%±0.31%(F = 188.2,P < 0.01)。结论 我们描述了 OCTA 在 MCA 脉管系统成像中的新应用。移植物和 MCA 的血管重塑在 1 个月时出现,并在手术后持续 3 个月。
