NCT05705778

Brief Summary

This prospective study aims to observe the predictive effect of peripheral blood plasma biomarker on the outcome of treatment in children with different types of amblyopia. We also investigated the mechanism of neuromodulation in the visual development of amblyopic children.

Outcome Measures

Primary Outcomes (1)

  • Plasma protein predictor screening for visual acuity improvement following amblyopia therapy using Tandem Mass Tags proteomics

    Peripheral blood will be collected prior and after treatment. The plasma will be separated and Tandem Mass Tags will be used for proteomics. We will detect the different expression of plasma protein between successfully treated and untreated amblyopia patients to find biomarkers that predict amblyopia treatment success. Amblyopia treatment success is defined as best corrected visual acuity (BCVA) improvement of 3 or more logMAR lines.
