[Results of trabeculectomy in congenital glaucoma].

Congenital glaucoma has a very serious prognosis. It represents the first cause of blindness in Tunisian children. Trabeculectomy introduced by Cairns in 1968, was initially proposed as second-line treatment in congenital glaucoma surgery. It has now become more frequently used as first-line treatment in this indication. We have already used this technique directly in 35 children suffering from congenital glaucoma with a total of 54 eyes. Forty four eyes underwent a single operation, ten eyes underwent two to four trabeculectomies. Then study of these cases with a mean follow up of 24 months shows an overall success rate of 64% after one trabeculectomy, with or without additional medical treatment. The study of tonometric diagrams shows that the successful results obtained after 3 months persisted in the long term. Trabeculectomy gives better results in congenital glaucoma with intraocular pressure greater than 40 mmHg. Repeated operations are sometimes necessary. In these cases, postoperative subconjunctival 5 fluorouracil (SFU) did not improve the surgical outcome.
