[Computer method for fusional reserves evaluation with objective control of fusion break].

Area of Science:

• Ophthalmology and Vision Science
• Human-Computer Interaction
• Biomedical Engineering

Context:

• Assessing fusional reserves is crucial for understanding binocular vision function.
• Traditional methods can be subjective and lack precision.
• Developing objective and reliable measurement tools is an ongoing challenge in vision science.

Purpose:

• To develop and validate an interactive computer program for assessing fusional reserves.
• To enhance the accuracy of measuring the moment of fusion break during convergence/divergence changes.
• To provide an objective method for evaluating binocular vision and fusion capabilities.

Summary:

• A novel interactive computer program was developed to assess fusional reserves by monitoring subjective reports of fusion break.
• The program utilizes purely binocular stimuli, specifically random-dot stereograms with dynamic markers, to control the visual test.
• The disappearance of a marker within the stereogram indicates fusion break, allowing subjects to pinpoint the exact moment and enabling experimenter verification.

Impact:

• The developed method demonstrates sufficient reliability for assessing fusional reserves, confirmed by statistical analysis of measurements in 72 subjects.
• This technology offers a more precise and objective tool for clinical and research applications in ophthalmology.
• It has the potential to improve the diagnosis and management of binocular vision disorders.
