A randomized controlled study of the anticicatricial effect of preoperative subconjunctival triamcinolone acetonide (TA) on the filtering bleb in 89 eyes (61 cases) of refractory glaucoma showed that the rates of surgical success in the TA groups were 77.3-89.0% and that in the control group 48.0%. The varying dosages of TA produced insignificant differences; however, the proportional distribution of the types of filtering blebs differed significantly among the various dosage groups, and complications occurred mostly in the high dosage group of 12 mg. The study indicated that TA raised the surgical efficacy in treating refractory glaucoma and the dosages of choice were 4-8mg.
