Fixation Stability Data for Unilateral Deprivation Amblyopia Patients and Controls

Seven adults with unilateral deprivation amblyopia and 18 adults with normal vision were tested during binocular and monocular viewing. The data, authored by M. Nasir and last updated in May 2026, likely contains eye-tracking metrics like bivariate contour ellipse area (BCEA), microsaccade rate, amplitude, and slow drift velocity. Findings demonstrate lasting fixation stability deficits in adults with a history of early visual deprivation.

Use Cases

• Analyzing fixation stability deficits based on bivariate contour ellipse area (BCEA) metrics mentioned in the description
• Comparing microsaccade rate and amplitude between amblyopic patients and control groups under different viewing conditions
• Modeling the relationship between slow drift velocity and monocular versus binocular viewing described in the results
• Investigating the lasting impact of early visual deprivation on oculomotor function as discussed in the study

Strengths

• Data includes a control group of 18 adults with normal vision for comparison.
• Study evaluates fixation stability under three specific viewing conditions: binocular, monocular closed-loop, and monocular open-loop.
• The dataset is shared under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• The dataset is very small at 81.5 KB, indicating limited scope.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The sample size of the patient group is limited to 7 individuals.
