Fixation Stability Measurements in Adults with Unilateral Deprivation Amblyopia

Eye-tracking data from a study of 7 adults with unilateral deprivation amblyopia and 18 adults with normal vision. The dataset likely contains measurements of fixation stability, microsaccade rate, amplitude, and slow drift velocity under binocular and monocular viewing conditions. The data was published by M. Nasir on figshare under a CC-BY-4.0 license and was last updated in May 2026.

Use Cases

• Analyzing fixation stability deficits based on bivariate contour ellipse area (BCEA) measurements.
• Comparing microsaccade rates and amplitudes between amblyopic and fellow eyes under different viewing conditions.
• Modeling the relationship between slow drift velocity and visual deprivation history.
• Benchmarking oculomotor performance in clinical populations against a control group.

Strengths

• Includes data from a defined clinical population (7 patients) and a control group (18 individuals).
• Measurements were taken under multiple controlled viewing conditions (binocular, monocular closed-loop, monocular open-loop).
• Published under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (1.5 MB), which may limit the scope of statistical analysis.
