To evaluate the safety and efficacy of the surgical use of autologous plasma rich in growth factors fibrin membrane (mPRGF) in improving corneal wound healing and regeneration in a variety of complex ocular surface defects.
Chart review on 15 eyes of 14 included patients undergoing ocular surface intervention using intraoperative mPRGF at the Bascom Palmer Eye Institute and at the Instituto Oftalmológico Fernández-Vega was performed. Patients were grouped based on type of intervention or condition (penetrating keratoplasty, superficial keratectomy, neurotrophic or persistent corneal ulcers, and corneal perforation). Patients were followed for an average of 11 ± 5 months. Main outcomes measured were mPRGF dissolving time, best-corrected visual acuity, and evidence of any persistent epithelial defects, rejections, or complications.
All 15 eyes underwent successful placement of mPRGF. Average dissolving time for fibrin membrane was 21 ± 3 days. mPRGF resulted in total healing of the corneal defects in 13/15 (86.7%) of the treated eyes and partial healing in 2/15 (13.3%) eyes in which persistent epithelial defects were noted on follow-up. Visual acuity improvement was seen in 9/15 (60%) of the cases.
The use of autologous mPRGF in the healing and regeneration of the ocular surface is a secure and efficacious surgical option. Our data demonstrate that PRGF fibrin membrane should be contemplated as an important tool to optimize ocular surface regeneration in complex cases.
评估富含生长因子的自体富血小板纤维蛋白膜(mPRGF)在改善各种复杂眼表缺损的角膜伤口愈合和再生中的安全性和有效性。
对在 Bascom Palmer 眼科研究所和 Instituto Oftalmológico Fernández-Vega 接受术中 mPRGF 眼表面干预的 14 名患者的 15 只眼进行图表回顾。根据干预类型或疾病(穿透性角膜移植术、浅层角膜切除术、神经营养性或持续性角膜溃疡和角膜穿孔)对患者进行分组。患者平均随访 11±5 个月。主要观察指标为 mPRGF 溶解时间、最佳矫正视力以及任何持续性上皮缺损、排斥或并发症的证据。
所有 15 只眼均成功植入 mPRGF。纤维蛋白膜的平均溶解时间为 21±3 天。mPRGF 使 15 只治疗眼中的 13 只(86.7%)角膜缺损完全愈合,2 只(13.3%)持续上皮缺损的眼部分愈合。9 只(60%)眼的视力有所改善。
自体 mPRGF 用于眼表面的愈合和再生是一种安全有效的手术选择。我们的数据表明,PRGF 纤维蛋白膜应该被视为优化复杂病例眼表面再生的重要工具。
