Summary
Persistent corneal epithelial defects (PCEDs) after pars plana vitrectomy (PPV) are common. Management varies from conservative to advanced therapies like topical insulin, with further research needed.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Persistent corneal epithelial defects (PCEDs) following pars plana vitrectomy (PPV) pose a significant clinical challenge.
- These defects can lead to severe complications including corneal scarring and vision loss.
Purpose of the Study:
- To review the prevalence and risk factors of PCEDs after PPV.
- To summarize current management strategies for PCEDs in the context of PPV.
Main Methods:
- A systematic review of English-language studies was performed.
- Literature search conducted using PubMed and Embase databases.
Main Results:
- Prevalence of PCEDs post-PPV ranged from 0% to 78.37%.
- Risk factors include diabetes mellitus and intraoperative use of C3F8 gas.
- Management options span from bandage contact lenses to topical insulin.
Conclusions:
- PCEDs after PPV are multifactorial, requiring individualized treatment approaches.
- Advanced therapies like serum-based treatments and topical insulin show promise.
- Further prospective research is necessary to optimize treatment outcomes.
