Clinical features and biometric profile of patients presenting with unilateral high myopia.
Article in BMC ophthalmology, 2026. 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
backgroundUnilateral myopia, though less common than bilateral myopia, presents unique clinical challenges. This study aimed to explore the prevalence and clinical characteristics of children presenting with unilateral myopia.
methodsChildren presenting with unilateral high myopia at a tertiary care center, with a cycloplegic spherical equivalent (SE) ≤ -5D in one eye and ≥ -3D in the other, between January 2022 and January 2023, were recruited. A comprehensive review of their birth records and ocular examination was undertaken. Ocular biometric parameters, including axial length (AL), keratometry (K), and lens thickness (LT), were measured by IOLMaster 700, and the progress of refractive error since diagnosis was noted.
resultsThe study analyzed 25 patients with a mean age of 11.9 years (1-12 years) and a mean follow-up of 24.45 ± 2.4 months. Axial myopia was found in 84% of patients, and optic nerve abnormalities were present in 40%. There was associated amblyopia in 32%. The difference in the inter-eye AL, K, and LT was 0.85 ± 0.45 mm, 0.35 ± 0.20 D, and 0.12 ± 0.05 mm. Mean annual myopic progression in these eyes was 0.74 D (0.2-1.5 D).
conclusionsUnilateral myopia in a samples Indian population presents unique clinical characteristics. Unilateral axial myopia in a patient should prompt us to take a detailed birth history and look for optic nerve abnormalities. Amblyopia is seen in a significant proportion of unilateral myopes, and their myopic progression was 0.74D/year in our cohort.
