Swelling of the central retina, or "macular oedema" is the commonest cause of visual loss in diabetic retinopathy.\n\nDiabetic macular oedema is treated with laser coagulation to the macular area according to established guidelines which take into account the extent of the leak and its proximity to the centre of the macula, the "fovea". This treatment does not, however, always work and is inherently destructive.\n\nIntravitreal injection of crystalline steroids has been proposed as a new modality to treat clinically significant diabetic macular oedema.\n\nTo determine by means of a prospective, double-masked, randomised, placebo-controlled trial to determine whether an intravitreal injection of triamcinolone three months or more after focal or grid laser photocoagulation for clinically significant diabetic macular oedema will improve the visual acuity of eligible eyes.
