Imaging of trabeculectomy blebs with Visante anterior segment optical coherence tomography after digital ocular compression.
Article in Japanese journal of ophthalmology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeWe investigated changes in intrableb morphology of functioning trabeculectomy blebs with anterior segment optical coherence tomography (AS-OCT) after digital ocular compression.
methodsSixty-eight patients who underwent fornix-based trabeculectomy were recruited from Seoul St. Mary's Hospital. Intraocular pressure (IOP) and AS-OCT images were taken before and after ocular compression. Bleb height and wall thickness and height and length of the internal cavity were measured by AS-OCT. The hyporeflective areas and number of microcysts were checked on both vertical and horizontal images. AS-OCT parameters for IOP change, bleb morphology, and interval between surgery and examination were compared.
resultsOcular compression yielded significant changes for all AS-OCT parameters other than maximum bleb wall thickness in the 6- to 12-month period after surgery. Correlation between IOP change and AS-OCT parameters was greatest for the horizontal and vertical length of the internal cavity (Spearman rank correlation coefficient ρ = 0.717, P < 0.0001, and ρ = 0.866, P < 0.0001, respectively). Response to ocular compression in cystic blebs was mainly enlargement of the internal cavity and increase in bleb height. However, in diffuse filtering blebs, increases in the size of the hyporeflective areas and the number of microcysts were the main findings. From 12 months postoperatively, changes in AS-OCT intrableb parameters were significantly reduced, showing no difference after ocular compression.
conclusionDigital ocular compression may be useful in maintaining bleb morphology when it is used for 6 months postoperatively. Response to ocular compression as assessed by bleb morphology was different.
