Summary
Eye-tracking shows promise for evaluating cleft lip and/or palate (CL+/-P) outcomes, but inconsistent research methods hinder its full potential. Standardized protocols are needed for reliable results in CL+/-P studies.
Area of Science:
- Ophthalmology and Visual Science
- Plastic Surgery Research
- Human Factors Engineering
Background:
- Eye-tracking is increasingly utilized in cleft lip and/or palate (CL+/-P) research.
- Current research lacks standardized methodologies for eye-tracking studies in this field.
- This variability impacts the reliability and comparability of findings.
Purpose of the Study:
- To conduct a literature review of eye-tracking methodology and outcomes in CL+/-P research.
- To identify trends and variations in study designs.
- To highlight the need for standardized protocols.
Main Methods:
- Searched PubMed, Google Scholar, and Cochrane databases up to August 2022.
- Included studies using eye-tracking with CL+/-P image stimuli and reporting outcomes via areas of interest (AOIs).
- Screened articles by two independent reviewers based on predefined inclusion/exclusion criteria.
Main Results:
- 16 out of 40 identified articles met the criteria.
- Studies showed significant variation in design, particularly in AOI usage.
- Few studies integrated eye-tracking data with participant outcome scores.
Conclusions:
- Eye-tracking is a valuable tool for assessing CL+/-P appearance outcomes.
- The field is limited by a lack of standardized research methodology and diverse study designs.
- Development of a replicable protocol is crucial for maximizing the technology's potential in future CL+/-P research.
