Abstract

Abstract : Objective: To investigate the change of chronic diabetic macular oedema (DMO) in vitrectomised eyes when the administration of sodium–glucose cotransporter 2 (SGLT2) inhibitors is initiated as a systemic medical treatment. Methods and analysis: This study involved 10 eyes of five patients with chronic DMO lasting more than 6 months who had previously undergone vitrectomy and whose systemic medical treatments were newly changed to SGLT2 inhibitors. In this study, chronic DMO was defined as persistent diffuse macular oedema despite ophthalmic treatment in patients with diabetes. Patients who received antivascular endothelial growth factor therapy or steroids administration, or change of eye-drop medication from at 3 months before and after the initiation of SGLT2 inhibitors, were excluded. In this study, visual acuity (VA) and central retinal thickness (CRT, μm) prior to and at 3, 6 and 12 months after the initiation of SGLT2 inhibitors were retrospectively compared. The Wilcoxon signed-rank test was used for statistical analysis. Results: In the 10 treated eyes, from at baseline to at 3, 6 and 12 months after the initiation of SGLT2 inhibitor, median VA (logMAR) improved from 0.35 to 0.15 (p=0.038), 0.2 (p=0.157) and 0.2 (p=0.096), respectively, and median CRT significantly reduced from 500.5 µm to 410 µm (p<0.01), 378 µm (p<0.01) and 339 µm (p<0.01), respectively. Conclusion: Although this study involved only five patients, our findings indicate that SGLT2 inhibitors might have structural efficacy for chronic DMO in vitrectomised eyes.
