Trabeculectomy profile in an ophthalmological reference service in Ceará: quantitative retrospective study

Abstract

ABSTRACT Objective: To know the profile of trabeculectomy, in addition to the success rate in controlling intraocular pressure in patients with glaucoma. Methods: A retrospective, observational study, with medical records of patients with glaucoma, followed up at an ophthalmological reference center, who underwent trabeculectomy from January 1, 2016 to May 31, 2017, by a single experienced surgeon. The success rate was considered with an intraocular pressure < 21 mmHg, for high intraocular pressure glaucoma, and a reduction of at least 20% for normal intraocular pressure glaucoma. Results: We analyzed 160 eyes, among which the majority (63.1%) were female, and 46.25% were aged between 61 and 80 years. There was a predominance of primary open-angle glaucoma in 67.3% of cases, and most were in an advanced stage (91.9%). After performing trabeculectomy, in 39.4% of the eyes, interventions were required at some point in the postoperative period; however, when comparing the groups that presented, or not, these procedures, the evolution of intraocular pressure showed no statistically significant difference. The postoperative period follow-up showed that the intraocular pressure remained below 21 mmHg and with reductions greater than 40% of the baseline intraocular pressure value. Conclusion: The success rate of trabeculectomy exceeded 90%, with a small rate of complications, noting that trabeculectomy is a safe procedure with significant success in the glaucoma control in the state of Ceará.
