Management of Patients With DME With Good Visual Acuity in Routine Clinical Practice

To determine outcomes of eyes with diabetic macular edema (DME) and best visual acuity (BVA) of 20/25 or better in routine clinical practice.

Retrospective study of 72 patients with DME and BVA of 20/25 or better. Patients were divided by anti-vascular endothelial growth factor (VEGF) treatment regimen: early (Group A), delayed (Group B), and none (Group C).

Group A had higher baseline central subfield thickness (CST) (325 ± 62 µm) compared to Groups B (292 ± 24 µm) and C (296 ± 35 µm) (P = .033). All groups had similar 24-month CST (299 ± 62 µm, 280 ± 64 µm, 296 ± 65 µm; P = .61). There was no difference in baseline BVA among groups (81.9 ± 2.4, 83.2 ± 2.4, 82.4 ± 2.5 Early Treatment Diabetic Retinopathy Study [ETDRS] letters, respectively; P = .290), but at 6 months, Group A had lower BVA (76.6 ± 9.6 ETDRS letters) than groups B (81.9 ±3.3 ETDRS letters) and C (82.4 ± 5.0 ETDRS letters) (P = .008). There was no difference among groups in 24-month BVA (78.9 ± 6.6, 78.4 ± 12.3, and 80.6 ± 6.9 ETDRS letters, respectively; P = .448).

Although observation may be indicated in eyes with stable BVA and CST less than 300 µm, anti-VEGF stabilizes BVA in eyes with CST greater than 300 µm and eyes with declining BVA. [.
