Persistent Fetal Vasculature: Current Insights and Future Directions

ABSTRACT

Background and Purpose

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.

Methods

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.

Conclusion

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.
