This review summarizes methods for measuring visual suppression in amblyopia patients. Current clinical tools are limited, highlighting a need for better quantification methods in practice.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Visual Science

Background:

  • Suppression is the cortical inhibition of visual information from one eye.
  • Amblyopia, or 'lazy eye,' is a developmental disorder affecting visual acuity.
  • Accurate quantification of suppression is crucial for effective amblyopia management.

Purpose of the Study:

  • To identify and collate methods, techniques, and tools for measuring and quantifying suppression.
  • To review the current landscape of suppression quantification in the clinical management of amblyopia.

Main Methods:

  • A scoping review following PRISMAScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Scoping Reviews) guidelines.
  • Inclusion of peer-reviewed papers describing methods to quantify suppression in amblyopic patients.

  • Analysis of 75 included papers.

    • Main Results:

    • Suppression quantification is feasible in children as young as 3 years old.
    • Methodologies are categorized by target size, electrophysiology, or contrast.
    • Common clinical tools include the Worth four-dot test and neutral density filters; experimental tools often use dichoptic motion coherence tests.

    Conclusions:

    • Clinical implementation of suppression quantification is limited due to a lack of fine-graded continuous scale tools.
    • Advanced quantification tools are primarily used in lab-based research and not yet commercially available.
    • Future research should prioritize the development of improved clinical tools for suppression quantification.
