ABSTRACT
BACKGROUND AND OBJECTIVE: To determine outcomes of eyes with diabetic macular edema (DME) and best visual acuity (BVA) of 20/25 or better in routine clinical practice. PATIENTS AND METHODS: 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). RESULTS: 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). CONCLUSION: 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.

BACKGROUND AND OBJECTIVE: To determine which optical parameter profiles (OPPs) can be utilized to improve the visualization of epiretinal membranes (ERMs) and the internal limiting membrane (ILM) using a three-dimensional heads-up microscope during 25-gauge pars plana vitrectomy. PATIENTS AND METHODS: Fourteen independent graders were asked to complete a questionnaire comparing each of the OPPs against the unaltered control image for each given surgical case. RESULTS: Analysis of the graders' responses indicated that higher values of hue are correlated with better visualization of ERM/ILM before and after dye application. There was overall agreement that OPPs could be used to enhance the visualization of the ERM and ILM during surgery. CONCLUSIONS: The use of OPPs to improve the visualization of specific structures is still new and heavily dependent on surgeon preference. The authors' study shows that some OPPs may enhance the visualization of the ERM and ILM during macular surgery. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:584-587.].
