Quantification of Oculomotor Responses and Accommodation through Instrumentation and Analysis Toolboxes

Area of Science:

• Ophthalmology and Vision Science
• Neuroscience
• Biomedical Engineering

Background:

• Traditional haploscope setups often rely on mechanical components, limiting customizable visual stimulation.
• A need exists for adaptable, software-driven visual stimulation systems for eye movement research.

Purpose of the Study:

• To introduce VisualEyes2020 (VE2020), a novel software-based visual stimulation and analysis system.
• To enable synchronized recording and analysis of eye movements and accommodative responses.
• To provide vision researchers and clinicians with a reproducible and shareable research tool.

Main Methods:

• Development of VE2020, a software-based visual stimulator for a novel haploscope.
• Integration of eye tracking and autorefractor systems for data acquisition.
• Creation of the Eye Movement Analysis Program (VEMAP) and Accommodative Movement Analysis Program (AMAP) for synchronized data processing.

Main Results:

• VE2020 facilitates the study of accommodation, vergence, and saccades.
• VEMAP and AMAP provide synchronized analysis of eye movement and accommodative data.
• The system minimizes operator reliance through objective software analysis and a graphical interface.

Conclusions:

• VE2020 offers a reproducible and objective software suite for vision research.
• The system supports a wide range of visual experiments with minimal coding expertise required.
• This advancement provides a valuable tool for understanding neural mechanisms of eye movements.
