Comparative optical coherence tomography study of differences in scleral shape between the superonasal and superotemporal quadrants.
Article in Japanese journal of ophthalmology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeTo determine the differences in scleral shape between the superonasal and superotemporal quadrants, the sites of scleral flap creation in trabeculectomy, using anterior segment optical coherence tomography (OCT).
methodsThirty-four right eyes of 34 enrolled subjects without ocular disease, with the exception of cataract or ametropia, were studied. Mean patient age was 63.2 ± 15.9 (standard deviation) years (range 28-84 years). The same examiner captured all images using anterior segment swept source OCT. The mean measurements were calculated from three images captured for each eye, 60° from the horizontal line passing through the pupillary center in the superonasal and superotemporal sclera. The radius of the scleral surface curvature and the area of the convex part of the sclera between the superonasal and the superotemporal quadrants were determined using image analysis software and the paired t test.
resultsThe radius of the scleral curvature was significantly different in the superonasal quadrant and superotemporal quadrant (34.3 ± 12.6 vs. 18.3 ± 3.6 mm, respectively; P < 0.001). The area of the convex part of the sclera was also significantly different in the superonasal and superotemporal quadrants (0.36 ± 0.1 vs. 0.57 ± 0.1 mm(2), respectively; P < 0.001).
conclusionsAnterior segment OCT analysis of the scleral shape revealed a more gradual scleral gradient in the superonasal quadrant compared with the superotemporal quadrant.
