Summary
Pars plana vitrectomy, a common eye surgery, does not significantly impact endothelial cell loss. This finding holds true even for diabetic patients, suggesting the procedure is safe for corneal health.
Area of Science:
- Ophthalmology
- Corneal Science
- Surgical Outcomes
Background:
- Endothelial cell loss is a concern following intraocular surgeries.
- Pars plana vitrectomy is frequently performed for various retinal conditions.
Purpose of the Study:
- To prospectively evaluate endothelial cell loss after pars plana vitrectomy (PPV) with and without lensectomy.
- To assess the safety of PPV regarding corneal endothelial integrity.
Main Methods:
- Prospective study involving 21 eyes undergoing PPV or PPV with lensectomy.
- Included 15 diabetic and 6 nondiabetic patients.
- Endothelial cell counts were measured preoperatively and postoperatively.
Main Results:
- Average endothelial cell loss ranged from 2.3% to 3.9%.
- No statistically significant difference was observed compared to preoperative counts.
- Phakic eyes and cases maintaining the anterior capsule showed minimal cell loss.
Conclusions:
- Pars plana vitrectomy appears to be safe concerning corneal endothelial cell loss.
- Maintaining the phakic state or anterior capsule integrity may further minimize cell loss.
- The procedure is a viable option for retinal conditions without significant risk to corneal endothelium.
