To determine the efficacy of the valvular needling to a year of evolution in patients with glaucoma and Ahmed glaucoma valve (AGV) implant.
This is a retrospective, longitudinal, observational, descriptive, cohort study. We obtained all the records of the patients with diagnosis of glaucoma and precedent AGV implant who had performed needling between 2006 and 2012. We collected data such as age, sex, visual acuity (VA), pachymetry, mean deviation presurgical and postsurgical, diagnosis of base, type and number of additional procedures performed, type of complications, number of medications presurgical and to a year after the surgery, preoperative intraocular pressure (IOP), on the first day, fist and second week; first, second, fourth, sixth, eighth, tenth and twelfth month. Took place a parametric analysis using a Student T test, using the statisticall package Graph Pad Prism 5.0.
We obtained a total of 112 eyes, 47 (41.96%) male, 65 (58.03%) female, with an mean age of 55.31 years (±21.7); the main diagnosis were primary-open angle Glaucoma in 42 patients (37.5%); Mean pachymetry was 556.92 (±74.86); presurgical VA in LogMar was 0.61 (±0.63) and postsurgical 0.70 (±0.61); the mean deviation campimetrica presurgical was 18.27(±7.82) and postsurgical 18.98 (±7.95); the average of the number of presurgical medicines was 3.16 (±0.83) and postsurgical 2.5 (±1.40). In regard to the IOP the mean preoperative was 18.32 (±5.45). Statistically significant differences were found in the majority of the shots, except in the week two and the second month.
The valve needling is an effective alternative to control IOP in patients with AGV implant, 30% of patients required the needling of the year has been the AGV implant, only 14.2% of the patients presented complications; the hypertensive peak was between the second and the fourth week. On average at two months is required hypotensive treatment for the control of the IOP; 58 patients required a new intervention, being a second needling the most frecuent; the number of drugs decreased a year of surgery; the majority of the patients had a severe campimetric damage, so there were no significant differences between the deviation mean campimetric, as well as not statistically significant changes in visual acuity presurgical and postsurgery.
