[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.
