Background: To identify the baseline factors influencing success following trabeculectomy with mitomycin C in a case series of African-Caribbean patients., Design: A prospective, observational and non-comparative cohort study., Participants: Forty-seven consecutive African-Caribbean patients (47 eyes) with glaucoma., Methods: Association between trabeculectomy survival and study factors was examined using Fisher's exact test and the Wilcoxon rank sum test at 12, 24 and 36 months following trabeculectomy. Logistic regression was used to establish the combination of factors best predicting survival., Main Outcome Measures: Surgical success was based upon intraocular pressure reduction to ≤21 mmHg, ≤18 mmHg and ≤15 mmHg without glaucoma medication (criterion 1), or intraocular pressure reduction to ≤21 mmHg, ≤18 mmHg and ≤15 mmHg with or without glaucoma medication (criterion 2)., Results: Trabeculectomy survival at 36 months was significantly decreased with the use of preoperative acetazolamide, pseudophakic status and higher preoperative intraocular pressure (P < 0.05). In pseudophakic eyes, there was a lower rate of success for criterion 2 when aiming for an intraocular pressure ≤15 mmHg at 2 years post-trabeculectomy, the odds ratio being 12., Conclusions: Three major independent risk factors were identified that influenced trabeculectomy failure at 3 years in African-Caribbean ethnicity: the preoperative use of acetazolamide, pseudophakic status and higher preoperative intraocular pressure. The presence of these risk factors may guide the clinician to use a more aggressive antiproliferative and postoperative management regime to enhance survival rates in this high-risk population., (© 2012 The Authors.

Background: To evaluate long-term outcomes and complication rates following trabeculectomy with mitomycin C in a case series of African Caribbean patients., Design: A prospective, observational and non-comparative case series., Participants: Forty-seven consecutive African Caribbean patients (47 eyes) with glaucoma., Methods: All patients underwent augmented trabeculectomy with mitomycin C for uncontrolled intraocular pressure (IOP). Survival analysis was performed with a minimum of 12 months' follow up., Main Outcome Measures: Surgical success was based upon IOP reduction to ≤ 21 mmHg, ≤ 18 mmHg and ≤ 15 mmHg without glaucoma medication (complete); or IOP reduction to ≤ 21 mmHg, ≤ 18 mmHg and ≤ 15 mmHg with or without glaucoma medication (qualified)., Results: The mean follow-up period was 48.6 months. At 3 years post-trabeculectomy 92.6% achieved a qualified success and 59.3% a complete success for an IOP ≤ 21 mmHg. At final follow up the mean IOP reduced from 33.7 mmHg to 13.1 mmHg (P < 0.0001). Survival rates were 96%, 90% and 86% at 12, 24 and 36 months, respectively, with a mean survival time of 97.4 months (95% confidence interval, 86.0-108.8) for an IOP ≤ 21 mmHg. Early postoperative hypotony requiring surgical intervention occurred in four (8.5%) patients. There were no cases of blebitis, endophthalmitis, suprachoroidal haemorrhage, malignant glaucoma or hypotony maculopathy., Conclusions: Good long-term stable IOP can be achieved with low complication rates and high success rates amongst African Caribbean patients following trabeculectomy with mitomycin C. A proactive postoperative management regime is needed to ensure trabeculectomy survival in high-risk populations., (© 2011 The Authors.
