Is single-stage two-muscle surgery of 7-11 mm enough for large-angle exotropia?
Article in International ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 report the effectiveness of single-stage two-muscle surgery of 7-11 mm in patients with large-angle exotropia.
methodsA retrospective analysis of 34 patients with a large-angle comitant exodeviation was conducted. Patients were classified as severe (group 1) if the average deviation was ≥ 50 prism diopters (PD) and moderate (group 2) if their deviation ranged from 30 to 49 PD. A successful outcome of surgery was defined as deviation within 12 PD of orthophoria/tropia for both distance and near.
resultsThe mean exodeviation was 49.5 ± 11.6 (range, 30-85) PD at distance and 50.3 ± 13.5 (range, 18-85) PD at near preoperatively. All patients underwent a recess/resect procedure. At the last visit, 25 (71%) of 34 patients in the entire group achieved successful alignment; it was higher in group 2 (81%) than in group 1 (67%); but the difference was not statistically significant (p = 0.45). Twelve patients had very poor vision (≤ counting fingers at 1 m) in one eye with a success rate of 83% in the short-term. Two patients had minimal asymmetrical abduction deficit and no patients reported permanent diplopia at the final postoperative evaluation.
conclusionLarge-angle exodeviations can be successfully corrected with a two-muscle surgical procedure without causing significant abduction deficiency. This choice has the advantage of 2 horizontal rectus muscles remaining untouched.
