Outcomes of Eyes With Diabetic Macular Edema That Are Lost to Follow-up After Anti–Vascular Endothelial Growth Factor Therapy

•In patients with nonproliferative diabetic retinopathy with diabetic macular edema treated with anti–vascular endothelial growth factor injections, vision was worse after being lost to follow-up for >6 months but recovered within 3 months after restarting therapy and remained stable until final follow-up an average of 502 days later.•Vision recovered regardless of pre–loss to follow-up diabetic retinopathy severity status.•Mean central foveal thickness increased after loss to follow-up but quickly returned to pre–loss to follow-up levels after resuming anti–vascular endothelial growth factor therapy.
