This review found no studies comparing local versus general anesthesia for vitrectomy surgery. More high-quality clinical trials are needed to determine the best anesthesia approach for pars plana vitrectomy.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Vitrectomy is a common ophthalmic surgery worldwide.
- Anesthesia for vitrectomy can be general or local (regional/topical).
- No current evidence-based guidelines exist for optimal anesthesia choice.
Purpose of the Study:
- To compare local versus general anesthesia in adults undergoing pars plana vitrectomy.
Main Methods:
- Searched multiple databases (Cochrane, MEDLINE, Embase) and trial registries up to July 2016.
- Included randomized controlled trials (RCTs) comparing local anesthesia modalities with general anesthesia.
- Excluded quasi-RCTs.
Main Results:
- No eligible studies were found that met the inclusion criteria.
- A meta-analysis and quality assessment could not be performed due to the lack of studies.
Conclusions:
- This systematic review found no clinical evidence to support or refute local versus general anesthesia for pars plana vitrectomy.
- High-quality clinical trials are required to establish the optimal anesthesia method.
