[The long-term cystic bleb appearance and safety after trabeculectomy with mitomycin C].
The clinical appearance of cystic blebs and the incidence of bleb infection were retrospectively evaluated in 215 trabeculectomies with mitomycin C. The incidence of cystic bleb formation in trabeculectomy was 79% (169/215). The cumulative incidence of the cystic bleb survival when using the Kaplan-Meier method was 73% in the 50th month after surgery. The incidence of large cystic bleb survival was better than that of small and localized cystic blebs. There was statistically significant difference. The incidence of cystic bleb survival without Seidel phenomenon and bleb infection was 96% in the first year after surgery and 91% in the third year. Bleb infections occurred in two of 169 eyes (1.2%). Bleb infection was successfully treated and there were no cases of endophthalmitis. The large cystic blebs had a higher incidence of bleb infection than the small ones. In one of 25 eyes treated with antibiotic eye drops after surgery, the Seidel test was positive and bleb infection occurred. The Seidel test was positive in 5 of 96 eyes in which antibiotic eye drops were not used and bleb infection occurred in one of these 5 eyes.
