INTRAOCULAR PRESSURE, TRABECULECTOMY, GLAUCOMA.Abstract
Introduction: trabeculectomy is still the most commonly used incision surgery to control the intraocular pressure in patients suffering from glaucoma.
Objective: to describe the factors influencing on the control of intraocular pressure after the trabeculectomy.
Methods: a descriptive, longitudinal-prospective study was carried out in 91 patients undergoing trabeculectomy at Abel Santamaria Cuadrado General Teaching Hospital from 2012 to 2015, where the control of intraocular pressure was described according to the variables that could influence on this result, applying descriptive statistics and chi-square test.
Results: the cases with adequate control presented no ocular antecedents (88.6%), moderate disease stage (65.7%), previous intraocular pressure ≤ 30 mmHg (72.9%) and absence of postoperative complications (84. 3 %). Patients with relatively adequate or inadequate control where male gender predominated (92.9% and 57.1% respectively), non-white skin patients (85.7%), history of trabeculectomy (57.1%), advanced damage and previous intraocular pressure> 30 mmHg (85.7%).
Conclusion: among the factors influencing on the adequate control of the intraocular pressure were: negative ocular history, previous intraocular pressure less than or equal to 30 mmHg, and absence of postoperative complications, whereas for a relatively adequate or inadequate control influenced on male patients, non-white skin, antecedent of previous trabeculectomy, advanced damage provoked by glaucoma and previous intraocular pressure greater than 30 mmHg.
