retinal neovascularization inhibition→microvascular protection
Statins may protect against diabetic retinopathy through reduction of retinal neovascularization, anti-inflammatory effects, and improvement of microvascular endothelial function. A systematic review and meta-analysis supports reduced incidence and improved visual outcomes. Evidence is primarily from observational studies and small clinical trials rather than large RCTs.
