To report on the outcomes of amniotic membrane transplantation (AMT) for corneal ulceration following infectious keratitis.
In this retrospective cohort study of 654 patients with culture-proven infectious keratitis from 8 hospitals in Galicia (Spain), a total of 43 eyes of 43 patients (6.6%) underwent AMT for postinfectious corneal ulceration. The indications for AMT were sterile persistent epithelial defects, severe corneal thinning or perforation.
AMT was successful in 62.8% of cases, with 37.2% requiring an additional surgery. Median time to healing was 40.0 days (IQR 24.2-101.7 days) and final BCVA was lower than baseline ( = 0.001). Ulcers were large (>3 mm) in 55.8% of cases. Previous herpetic keratitis and topical steroid use were more common in patients who received AMT ( < 0.001). 49 microorganisms (43 bacteria and 6 fungi) were isolated.
AMT is a therapeutic option for complications following infectious keratitis, which present with a sterile persistent epithelial defect, significant corneal thinning or perforation.
报告羊膜移植（AMT）治疗感染性角膜炎后角膜溃疡的结果。
本研究为回顾性队列研究，共纳入来自西班牙加利西亚 8 家医院的 654 例培养阳性的感染性角膜炎患者，其中 43 例（6.6%）43 只眼因感染性角膜溃疡行 AMT。AMT 的适应证为无菌性持续性上皮缺损、严重的角膜变薄或穿孔。
AMT 成功率为 62.8%，37.2%的患者需要进一步手术。愈合的中位时间为 40.0 天（IQR 24.2-101.7 天），最终 BCVA 低于基线（ = 0.001）。55.8%的溃疡较大（>3mm）。行 AMT 的患者中，既往单纯疱疹性角膜炎和局部皮质类固醇使用更为常见（ < 0.001）。共分离出 49 种微生物（43 种细菌和 6 种真菌）。
对于感染性角膜炎后出现无菌性持续性上皮缺损、明显角膜变薄或穿孔等并发症，AMT 是一种治疗选择。
