[Effectiveness of trabeculectomy trabeculotomy in the reduction of intraocular pressure in patients with primary congenital glaucoma].

OBJECTIVE: To evaluate the effectiveness of trabeculectomy trabeculotomy in the reduction of intraocular pressure in patients with primary congenital glaucoma. MATERIAL AND METHODS: A pre-experimental before and after study was conducted with several measurements after; patients with intraocular pressure≥21 mmHg were included, of both sexes, and children under six years, which had ​​the trabeculotomy trabeculectomy. Success was defined as the reduction of intraocular pressure<21 mmHg within three months after the procedure. For the descriptive analysis, medians with ranges and quartiles 25 and 75 were used. For the inferential analysis, we conducted a visual graphic and analysis of variance for repeated measures of Friedman. A value of p<0.05 was considered as significant. The software used was SPSSv15. RESULTS: 16 eyes were included with intraocular pressure 27.75 mmHg (23-40), vertical and horizontal corneal diameter of 14 mm (12-16), who had undergone trabeculectomy with mitomycin C trabeculectomy; at three months after surgery the intraocular pressure was 12.5 mmHg (8.5-23) (p<0.001) and no changes were observed in the corneal diameters. An eye with a flat anterior chamber was observed as an adverse effect. Thirteen eyes required topical hypotensors to achieve the target intraocular pressure. CONCLUSIONS: The treatment with trabeculectomy trabeculotomy in primary congenital glaucoma is effective in the reduction of the intraocular pressure.
