Macular, Foveal and RNFL Thickness Patterns in Amblyopia: A Comparative Study.

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
Purpose: The purpose of this study is to compare the macular thickness, foveal thickness, and retinal nerve fiber layer (RNFL) thickness in amblyopic eyes with those of fellow non-amblyopic eyes using spectral-domain optical coherence tomography (OCT). Methods: A cross-sectional, observational study was conducted with amblyopic subjects from August 2022 to December 2024. A pilot study was carried out using simple random sampling technique. The study involved OCT-based measurement of macular, foveal, and RNFL thickness in amblyopic and non-amblyopic eyes using standardized imaging protocols. Data were analysed using appropriate statistical tests (paired and independent t-tests) based on normality results to compare values across eye types and gender. Results: The results showed significantly higher macular, foveal, and RNFL thickness in amblyopic eyes compared to non-amblyopic eyes (p < 0.05), with no significant differences between anisometropic and mixed amblyopia subtypes. Gender had no significant effect on retinal thickness, except for superior RNFL thickness, which was higher in the anisometropic group of non-amblyopic eyes. Conclusion: This study confirms that amblyopia involves both functional and structural retinal changes, notably in the macula and RNFL, regardless of type or gender. OCT proves valuable in detecting these changes, and future studies should focus on axial length correction and post-treatment outcomes.
