| description | <b>Objectives:</b> to evaluate the efficacy of 0.7 mg dexamethasone intravitreal implant in the treatment of patients with diabetic macular edema through mean retinal sensitivity (MRS), best corrected visual acuity (BCVA), central retinal thickness (CRT) and fixation stability. <b>Methods:</b> patients (n = 50) with DME, best corrected visual acuity (BCVA) of 0.1 logMAR, and central retinal thickness (CRT) of ≥300 μm determined by optical coherence tomography were treated with 0.7 mg slow-release dexamethasone, and endpoints were evaluated one and three months after the injection. <b>Results:</b> The best corrected visual acuity, BCVA, whose mean values at baseline were 0.42 logMAR, improved significantly post dexamethasone injection, with mean values of 0.20 logMAR at one month and 0.24 logMAR at three months. The mean central retinal thickness, CRT, was 463 µm at baseline increasing to 297 µm at one month, and 315 µm at three months. Mean retinal sensitivity (MRS) was 12.31 dB at baseline. In line with other parameters, MRS also showed significant improvement at one month after slow-release dexamethasone treatment, with a mean value of 15.35 Db and the improvement was sustained at three months after injection, with a mean value of 14.71 dB. Fixation stability was assessed using the area of the third BCEA ellipse. At baseline, patients had an ellipse area of 53.68 degrees. At one month after injection, patients showed an improvement, with a mean ellipse area of 5.23 degrees, which was maintained at three months, with a mean ellipse area of 4.13 degrees. <b>Conclusions:</b> The dexamethasone implant of 0.7 mg met the efficacy endpoint for improvement in MRS, BCVA, CRT and fixation stability. |
