DR: diabetic retinopathy; NPDR: nonproliferative diabetic retinopathy; PDR: proliferative diabetic retinopathy; SD: standard deviation; DM: diabetes mellitus; HTN: hypertension; CKD: chronic kidney disease; BCVA: best-corrected visual acuity; HbA1c: hemoglobin A1c; CMT: central macular thickness. Statistically significant value. P value for DM duration should be < 0.001. |
