[Ultra-widefield angiography for retinal vein occlusion : How large is large enough?]
Article in Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe introduction of full fundus angiography (FAG) for retinal vein occlusion (RVO) has enriched diagnostic imaging; however, it is unclear how much of the retina has to be visualized to evaluate the risk of neovascularization. We investigated the 102° Spectralis camera to assess if imaging beyond the central 102° is necessary.
methodsIn this retrospective study we assessed 80 eyes of 80 patients with RVO to analyze central and peripheral ischemia using the ultra-widefield 102° Spectralis camera. The standard viewer software was used to delineate ischemic areas (IA) and to measure the amount of pixels of IA in correlation to the total amount of pixels in the peripheral image.
resultsAmong the 80 eyes with RVO there were 51 eyes with ischemic areas (central and/or peripheral), of which IA could be detected in 49 eyes by analyzing a fovea-centered FAG image. The average IA in these 51 eyes was 23.5% of the total image area and 53.7% of disc areas, respectively. DISCUSSION: A fovea-centered FAG image with a 102° angle appears to be sufficient to determine the clinically relevant extent of IA. Old recommendations and imaging methods should be rethought. The 102° Spectralis camera provides a clinically suitable, fast and exact method which might replace old methods to describe and document the extent of ischemia by disc areas.
