Open Label Extension of a Clinical Trial of Intravitreal Triamcinolone for Diabetic Macular Oedema-TDMX Study

Summary

This open label extension will treat all the eyes of study participants with active study medication (intravitreal triamcinolone) as well as standard laser treatment where appropriate. The specific aims will be to test the following hypotheses: * That intravitreal triamcinolone for diabetic macular oedema that persists or recurs after laser treatment remains efficacious over five years * That intravitreal triamcinolone for diabetic macular oedema that persists or recurs after laser treatment retains a manageable and acceptable safety profile over five years
