Ab interno vs ab externo microcatheter-assisted trabeculotomy for primary congenital glaucoma with clear cornea.
Article in Clinical & experimental ophthalmology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
importanceThis is the first comprehensive comparison between ab interno approach and ab externo approach for microcatheter-assisted trabeculotomy in primary congenital glaucoma with clear cornea.
backgroundAb externo microcatheter-assisted trabeculotomy is considered to be the gold standard for primary congenital glaucoma. The novel ab interno approach would intuitively be similar to ab externo approach for microcatheter-assisted trabeculotomy in eyes with clear cornea; however, there is no evidence yet.
designNon-contemporary comparison of retrospective case series.
participantsFifty-eight and fifty-seven consecutive primary congenital glaucoma eyes with clear corneas underwent ab interno and ab externo microcatheter-assisted trabeculotomy, respectively.
methodsRetrospective comparison of clinical outcomes.
main outcome measuresSurgical success was defined as a postoperative intraocular pressure of ≤21 mmHg with at least a 30% reduction from preoperative IOP with or without the use of anti-glaucoma medication (qualified and complete success, respectively).
resultsThe qualified success rate (87.9% vs 82.2%, P = .40) and complete success rates (81.0% vs 73.3%, P = .32) were comparable between groups. Complications were minimal and comparable. Less than 360° trabeculotomy (P = .009) and a higher number of previous surgeries (P = .03) were both associated with worse surgical outcomes. CONCLUSIONS AND RELEVANCE: Ab interno approach provide good and comparable outcomes as ab externo approach for microcatheter-assisted trabeculotomy in primary congenital glaucoma eyes with clear cornea. It should be considered as the initial choice in these patients with the benefit of sparing conjunctiva. Successful trabeculotomy with either technique during the first attempt is critical to overall success and underscores the need for proficiency before independent practice.
