Summary

This trial compares two surgical methods for diabetic patients with proliferative diabetic retinopathy who need vitrectomy. One method spares the central part of the retina (fovea), while the other removes the entire inner limiting membrane. The study will measure vision and eye structure over six months to see which approach leads to better outcomes.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Pars plana vitrectomy with either fovea sparing or complete internal limiting membrane peeling
What this could lead to: If successful, this could help surgeons choose a technique that better preserves central vision and eye health in diabetic patients needing vitrectomy.
What could go wrong: This is a small, early-stage trial with only 48 participants, so results may not apply to all patients. The procedures carry standard surgical risks like infection or bleeding.
