Comprehensive analysis of posterior segment characteristics in high myopic Turkish patients.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWe aimed to investigate the structural characteristics of high myopia (HM) in a Turkish cohort using spectral domain optical coherence tomography (OCT) and evaluate the relationship between axial length (AL) and various retinal, choroidal, and scleral parameters.
methodsA retrospective analysis of medical records and imaging data was conducted in HM patients examined at Dokuz Eylül University between January 2019 and January 2023. Eyes were categorized into three groups based on AL: Group 1 (26.00-27.49 mm), Group 2 (27.50-28.99 mm), and Group 3 (≥ 29.00 mm). Retinal, choroidal, and scleral parameters were quantitatively assessed, and posterior segment findings were analyzed across these groups.
resultsA total of 146 eyes from 91 patients (mean age: 46.55 ± 17.05 years) were included. Central foveal thickness was significantly lower in Group 1 compared to Group 2 (p = 0.017). Moreover, Group 1 exhibited lower values for average macular thickness, average macular volume, and scleral sink, along with higher subfoveal choroidal thickness values compared to both Group 2 and Group 3 (p < 0.05 for all comparisons). The most common posterior segment findings were peripapillary atrophy (91.8%), tilted disc (47.3%), vitreomacular adhesion (39.0%), and posterior staphyloma (PS, 27.4%). Group 3 exhibited the most advanced stages of myopic maculopathy among the groups (p = 0.001). 'Plus' lesions, defined as the presence of macular neovascularization (MNV), Fuchs spots, or lacquer cracks, were detected in 14.4% of eyes. Pathologic myopia was diagnosed in 49.3% of eyes, including 47.2% based on myopic maculopathy stage and 0.7% each on the presence of PS, active MNV, or scarred MNV. Active MNV was more frequent in Group 3, while scarred MNV was predominant in Group 2.
conclusionsPresent findings highlight the progressive nature of structural changes associated with increasing AL in HM patients, emphasizing the importance of early detection and monitoring of posterior segment complications. This study provides valuable insights into the prevalence and distribution of myopia-related complications in a Turkish population, aiding in the clinical management of HM.
