GCG and vitreous hemorrhage: In a subgroup analysis of 32 695 patients with preexisting DR, GLP-1 RAs were not associated with progression to proliferative DR (HR, 1.06; 95% CI, 0.97-1.15) or diabetic macular edema (HR, 0.98; 95% CI, 0.95-1.01) but were associated with a lower occurrence of vitreous hemorrhages (HR, 0.74; 95% CI, 0.68-0.80), neovascular glaucoma (HR, 0.78; 95% CI, 0.68-0.88), or blindness (HR, 0.77; 95% CI, 0.73-0.82).
