摘要目的 观察玻璃体切割手术治疗永存胚胎血管(PFV)的临床效果.方法 回顾分析11例PFV患儿14只眼的临床资料.患眼中,后部PFV 1只眼,联合PFV 13只眼.所有患儿均行玻璃体切割手术.其中,同时行晶状体切除手术7只眼,视网膜切开切除手术5只眼,视网膜切开切除及巩膜外环扎手术1只眼.观察手术中及手术后并发症发生情况.手术后随访时间8～74个月,平均随访时间44个月.对比分析患儿手术前后视力和眼压变化情况.结果 手术中所有患儿均未发生并发症.14只患眼中,手术成功12只眼,占86.0%;手术失败2只眼,占14.0%.手术后视力较手术前视力提高5只眼,占35.7%;视力不变4只眼,占28.6%;视力下降5只眼,占35.7%.手术后眼压较手术前眼压升高2只眼,占14.3%;眼压不变11只眼,占78.6%;眼压下降1只眼,占7.1%.手术后持续性低眼压1只眼,占7.1%;复发性视网膜脱离1只眼,占7.1%.结论 玻璃体切割手术治疗PFV可防止并发症发生,使部分患儿视力提高.

abstractsObjective To observe the effects of vitrectomy for persistent fetal vasculature (PFV).Methods The clinical data of 11 patients (14 eyes) with PFV, including posterior PFV (one eye) and combined PFV (13 eyes), were retrospectively analyzed. Vitrectomy was performed for all patients,lensectomy was performed for seven eyes, retinotomy was performed for five eyes, retinotomy and scleral buckling was performed for one eye. Intraoperative and postoperative complications were observed. The follow-up period ranged from eight to 74 months, with the mean of 44 months. The visual acuity (VA) and intraocular pressure before and after surgery were comparatively analyzed. Results There were no intraoperative complications in all the patients. The surgery was performed successfully in 12 eyes (86.0 %)and failed in two eyes (14. 0%). The postoperative VA of five eyes (35.7%) increased, four eyes (28. 6%)didn't change and five eyes (35.7%) decreased. The postoperative intraocular pressure of two eyes (14. 3%) increased, 11 eyes (78. 6%) didn't change and one eye (7. 1%) decreased. There was one eye with persistent hypotension and one eye with recurrent retinal detachment after surgery. Conclusion Vitrectomy can prevent complications and improve visual acuity in some PFV patients.
