Impact of horizontal and vertical posterior pole steepness on the dimensions of idiopathic macular hole.
Article in International journal of retina and vitreous, 2025. 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
backgroundMacular holes (MH) vary immensely with respect to size and shape among different individuals. In an attempt to see if the curvature of the retinal pigment epithelium has any role, we aimed to analyse the influence of horizontal and vertical posterior pole steepness on idiopathic macular hole dimensions.
methodsThis was a retrospective observational study done in eyes with a diagnosis of idiopathic macular hole. Various MH parameters like baseline hole parameters like minimum linear diameter (MLD), baseline hole diameter (BHD), and hole angles were calculated. Steepness in the form of tangent angles was measured in both horizontal and vertical meridian at 6 mm and under the MH margins at 1.5 mm.
results52 eyes of 52 patients were included. Horizontal MLD showed weak correlation with average horizontal hole angle (r=-0.28, p = 0.04); average vertical hole angle (r=-0.28, p = 0.04). Horizontal BHD showed significant correlation with the horizontal hole margin tangent apical angle (r=-0.46, p = 0.001); average horizontal hole angle (r=-0.45, p = 0.001). Vertical MLD showed correlation with average horizontal hole angle (r=-0.28, p = 0.04) and average vertical hole angle (r=-0.33, p = 0.03). Vertical BHD showed correlation with horizontal hole margin tangent apical angle (r=-0.38, p = 0.004) and vertical hole margin tangent apical angle (r=-0.31, p = 0.03); vertical 6 mm tangent apical angle (r=-0.36, p = 0.01). On multivariate regression analysis, factors favouring a type 2 closure include, lower superior hole angle and higher inferior to superior tangent base angle ratio.
conclusionHole margin tangent angles were seen to correlate with the size and shape of the hole. Future studies with bigger sample size are required to validate it further.
