Abstract：
UNASSIGNED: Persistent fetal vasculature (PFV) is a complex congenital ocular condition, characterized by the incomplete regression of the embryonic hyaloid system. It encompasses a spectrum of abnormalities, affecting various ocular structures and presenting a range of fetal hyaloid remnants. Despite its long-standing recognition, the full extent of PFV\'s manifestations continues to evolve, unveiling novel findings, primarily driven by advancements in clinical experience and imaging techniques. This review focuses on the evolution of PFV management, emphasizing the disease heterogeneity and the consequent challenges in diagnosis and treatment.
UNASSIGNED: We present a comprehensive guide on PFV based on the current evidence, detailing its recognition, associated anatomical variations, the intricacies of surgical indications and techniques, and postoperative expectations.
UNASSIGNED: The progress over the last decade in innovative instruments and surgical techniques has not only enhanced functional and anatomical outcomes but also enriched our understanding of PFV. However, continued exploration and research remain pivotal for future breakthroughs in more effectively understanding and managing this complex ocular anomaly.

摘要：
■持续的胎儿脉管系统（PFV）是一种复杂的先天性眼部疾病，其特征是胚胎玻璃样系统的不完全回归。它包括一系列异常，影响各种眼部结构，并出现一系列胎儿泪液残留物。尽管得到了长期的认可,PFV表现的全部范围继续演变，揭晓新颖的发现，主要由临床经验和成像技术的进步驱动。这篇综述的重点是PFV管理的演变，强调疾病的异质性以及随之而来的诊断和治疗挑战。
■我们根据目前的证据提出了关于PFV的全面指南，详细说明了它的认可，相关的解剖学变异，手术适应症和技术的复杂性，和术后期望。
■在过去十年中，创新器械和外科技术的进步不仅增强了功能和解剖学结果，而且丰富了我们对PFV的理解。然而,持续的探索和研究对于更有效地理解和管理这种复杂的眼部异常的未来突破仍然至关重要。
