Ocular biometric profile and clinical characteristics of high myopia in Indian children.
Article in Indian journal of 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
purposeTo profile ocular biometric parameters and clinical features in Indian children with high myopia.
methodsWe conducted a retrospective chart review of electronic medical records at a tertiary care center from September 2023 to March 2025. Children ≤16 years with high myopia (spherical equivalent [SE] ≤ -6.00 D) and complete biometric data were included. Cycloplegic refraction, axial length (AL), keratometry (K), anterior chamber depth (ACD), lens thickness (LT), central corneal thickness, and clinical findings of one eye per patient (left eye by convention) were extracted and analyzed. Correlations between SE and biometric variables were assessed using Pearson's correlation and multiple linear regression.
resultsA total of 123 eyes from 123 patients (mean age 11.2 ± 3.5 years; 53% male) were analyzed. Mean SE was -9.84 ± 2.77 D (range -6.0 to -18.9 D), and mean AL was 26.39 ± 1.39 mm (range 23.75-30.46 mm). SE showed a strong correlation with AL (r = -0.777, P < 0.001) and a moderate correlation with LT (r = -0.281, P = 0.001) but a negligible association with K. Multiple regression incorporating AL, K, ACD, and LT explained 70.8% of SE variance (adjusted R² = 0.789, P < 0.0001). Retinal changes were present in 32.5% of eyes, most commonly tessellated fundus (29%), and all eyes with AL >28 mm showed fundus abnormalities.
conclusionHigh myopia in Indian children is characterized by early axial elongation, severe refractive error, and early retinal changes. Axial length remains the principal determinant of myopia, though keratometry, lens thickness, and ACD provide additional predictive value.
