PURPOSE: To evaluate the efficacy of Molteno aqueous shunt as a primary surgical treatment in @entity726 . METHODS: Nonrandomized, interventional, retrospective clinical study. The @entity2790 ( @entity2790 ), survival rate and complications were analyzed in 30 @entity1 with @entity726 treated with Molteno implant. RESULTS: The mean follow-up time was 59.3 +/- 18.4 months. Preoperatively, the mean +/- SD @entity2790 was 32.8 +/- 7.5 mmHg (range 20-48), and the mean number of medications was 3.1 +/- 0.6. The mean @entity2790 decreased significantly (p < 0.001) to 17.7 and 15 mmHg at 3 and 6 months postoperatively. The mean number of medications decreased statistically significantly (p < 0.001) from the preoperative number 3.1 to 1.9 three months postoperatively. The number of medications continued to decrease significantly up to 3 years postoperatively. The qualified success rate (Kaplan-Meier estimate) was 97%, 93%, 90% and 85% at 1, 2, 3 and 4 years, respectively. Two @entity1 failed because of @entity8814 , two @entity1 developed @entity3169 and one @entity1 had @entity2687 . CONCLUSIONS: Molteno aqueous shunt as the first @entity726 procedure decreased @entity2790 effectively in @entity726 . Even after 4 years, the survival estimate was quite high. The @entity2790 decreased continuously during the first year after the surgery, and the medication was slowly tapered even up to 3 years postoperatively. It is suggested that it may be possible to postpone further surgical intervention during the first postoperative year after Molteno implantation even if the @entity2790 is not quite optimal.
