Outcomes of Trabeculectomy and Predictors of Success in Patients of African Ancestry With Primary Open Angle Glaucoma.
Article in Journal of glaucoma, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
PRÉCIS: Trabeculectomy in African ancestry individuals with primary open angle glaucoma (POAG) shows a 46% success rate and frequent complications, indicating that younger age and family history are significant predictors of surgical failure in this high-risk population.
objectiveTo investigate outcomes of trabeculectomy ab externo in African ancestry POAG patients and to analyze the impact of demographic and phenotypic factors on surgical success and complication rates. PATIENTS AND
methodsA retrospective case-control study enrolled 63 eyes of 55 POAG cases who underwent trabeculectomy ab externo. Data on demographics, family glaucoma history, surgical specifics, and pre/postoperative measures (intraocular pressure, visual acuity, visual field, medication usage, complications within 1 year) were collected. The analysis included linear/logistic regression models adjusting for inter-eye correlation.
resultsTrabeculectomy yielded success without additional medication in 46%, qualified success with medication in 22%, and surgical failure necessitating further intervention in 32% within 1 year. Subjects experienced a reduction in intraocular pressure (IOP) (46%), daily glaucoma medication (73%), and eye drop usage (67%) 1-year post-trabeculectomy (all P <0.001). However, there was a postoperative decline of 56% in visual acuity (VA) ( P <0.001) and a significant worsening of visual field parameters, including a 14% decrease in mean deviation ( P =0.02) and a 19% decrease in visual field index ( P =0.004). Fifty-nine percent of patient eyes experienced complications within 1 year of surgery. Univariate analysis of predictive factors for surgical outcomes revealed that younger age at surgery ( P =0.01) and family history of glaucoma ( P =0.046) were predictive of lower rates of surgical success. Multivariable analysis revealed worse preoperative VA (OR: 0.79 per 0.1 LogMAR increases, P =0.02) was associated with a lower likelihood of surgical success.
conclusionThis study underscores the low rates of trabeculectomy success and high rates of complications in an African ancestry population with POAG. While the procedure exhibited positive effects on IOP control and medication reduction, our analysis found that multiple factors, particularly age, family history, and worse preoperative VA play crucial roles in influencing surgical success.
