Trabeculectomy Versus Ex-Press Glaucoma Filtration Device in Silicomacrophagocytic Open Angle Glaucoma Secondary to Silicone Oil Emulsification.
Trial report in Middle East African journal of ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
purposeTo compare the outcomes of Ex-PRESS device implantation versus trabeculectomy in patients with ocular hypertension after pars plana vitrectomy and silicone oil injection (SOI). MATERIALS AND
methodsTwenty-six consecutive eyes with ocular hypertension after pars plana vitrectomy and SOI were included in this study and randomized to one of two groups: A group treated with Ex-PRESS (model P50) placed under a scleral flap (Ex-PRESS group), and a group treated with trabeculectomy (trabeculectomy group). Complete success (intraocular pressure [IOP] <21 mmHg without medication) and qualified success rates (IOP <21 mmHg with one or two glaucoma medications) at 2 years postoperatively were analyzed. Between-groups comparison was performed with the Mann-Whitney U-test for continuous variables, and Fischer exact test for categorical data. Success rates between groups were compared using Kaplan-Meier life analysis and the log-rank test. P < 0.05 was considered statistically significant.
resultsIn the Ex-PRESS group, complete success was achieved in 73% eyes and qualified success in 81.8% of eyes. In the trabeculectomy group, complete success was achieved in 40% and qualified success was achieved in 60% of eyes. The difference in mean IOP between groups was statistically significant from the 3(rd) postoperative month onward (P = 0.007 at 3 months, P = 0.003 at 6 months, and P = 0.03 at 24 months).
conclusionEx-PRESS implantation was more effective than trabeculectomy in controlling IOP in ocular hypertensives after pars plana vitrectomy and SOI, but the surgical technique may require improvement.
