Abstract/OtherAbstract:
PURPOSE: To evaluate the clinical and visual outcome of an intravitreal injection of triamcinolone in patients with diabetic macular oedema refractory to laser treatment. MATERIAL AND METHODS: Prospective, interventional nonrandomised case series of 24 eyes of 24 patients that underwent intravitreal injection of 4 mg triamcinolone for chronic diabetic macular oedema refractory to previous laser treatment. All patients had best corrected visual acuity (bcva) on the LogMAR scale, near vision, slit-lamp biomicroscopy for the presence of clinically significant macular oedema, and intraocular pressure check at 1, 3, and 6 months. RESULTS: The average duration of macular oedema before the injection was 38.2 months (range=6-120 months) with the mean number of laser treatments before the injection being 2.2 (range=1-5). The visual acuity improved in 19 of the 23 (83%) eyes at 1 month, 16 of the 21 eyes (76%) at 3 months and six of 11 eyes (55%) at 6 months follow-up. The mean bcva improved by an average of 10, nine, and six letters, respectively, compared to the baseline at 1, 3, and 6 months (P=0.0002 at 1 month and 0.001 at 3 months with the Wilcoxon signed-ranked test). The intraocular pressure rose by an average of 2.4, 2.8, and 2.7 mmHg at the same follow-up visits. CONCLUSION: Intravitreal triamcinolone appears to be promising in the short term, for improving the vision in eyes with chronic diabetic macular oedema unresponsive to conventional laser treatment. Randomised controlled trials utilising varying doses of steroid are now required to define optimum treatment regimens.
