Persistent Corneal Epithelial Defect Following Pars Plana Vitrectomy: A Narrative Review.
Purpose: Persistent corneal epithelial defects (PCEDs) following pars plana vitrectomy (PPV) represent a significant clinical challenge, potentially leading to corneal scarring, vision loss, and other severe complications. This review aims to summarize the prevalence, associated risk factors, and management strategies for PCEDs in the context of PPV, providing evidence-based guidance for clinicians.
Methods: A comprehensive systematic review was conducted using PubMed and Embase databases, identifying English-language studies addressing PCEDs after PPV.
Results: The prevalence of PCEDs post-PPV varied widely, from 0% to 78.37%, influenced by intrinsic factors such as diabetes mellitus, which impairs corneal nerve function and healing, and extrinsic factors like intraoperative tamponade with C3F8. Management strategies ranged from conservative options like bandage contact lenses to advanced treatments like topical insulin.
Conclusion: PCEDs after PPV are multifactorial and demand individualized management. Advanced therapies, particularly serum-based treatments, and topical insulin, show promising outcomes. Further prospective research is warranted to refine these treatments.
