[Features of the electronic eikonometer for the study of binocular function]

Area of Science:

• Ophthalmology and visual neuroscience.
• Optical engineering and instrument design.

Context:

• Existing eikonometers have limitations in optical pathways.
• Accurate measurement of binocular disparity is crucial for visual perception.
• Aniseikonia affects visual comfort and performance.

Purpose:

• To present a novel electronic eikonometer for analyzing perceptive effects of binocular disparity.
• To detail the device's components, tests, and methodologies.
• To compare its advantages over existing eikonometers.

Summary:

• The electronic eikonometer features a unique design without intermediary optical systems.
• It includes a test library with Ogle Spatial Test for Aniseikonia, Fixation Disparity Test, and stereoscopic tests.
• Methodologies for operator and observer use are developed, with results from various corrected observers presented.
• Analysis links depth, disparity, and fusion, exploring retinal image size variations in different eye types and their impact on aniseikonia measurement and correction.

Impact:

• Provides a more accurate and versatile tool for diagnosing and managing aniseikonia.
• Enhances understanding of the relationship between binocular disparity, depth perception, and visual correction.
• Suggests future upgrades using high-resolution screens for an enriched test library.
