Computerized perimetry: possibilities for individual adaptation and feedback
1Department of Ophthalmology, University of Göteborg, Sahlgren's Hospital, Sweden.
Summary
Computerized perimetry acceptance can be improved with better feedback and adaptation. A new display format using symbol size may enhance patient understanding and engagement in visual field testing.
Area of Science:
- Ophthalmology
- Human-Computer Interaction
- Medical Technology
Background:
- Computerized perimetry is crucial for diagnosing and monitoring visual field defects.
- Patient acceptance and engagement are often low due to sparse feedback and lack of individual adaptation.
- Current result displays may not be intuitively intelligible for patients.
Purpose of the Study:
- To explore methods for improving patient acceptance and understanding of computerized perimetry.
- To introduce and evaluate a novel result display format for visual field testing.
Main Methods:
- Review of existing strategies to enhance perimetry feedback and adaptation.
- Proposal of a novel display format representing threshold level by symbol size.
- Discussion of potential benefits for patient comprehension and test experience.
Main Results:
- Several potential improvements identified: visual response feedback, active error correction, fixation prompts, and reaction time adaptation.
- A novel symbol-size-based display format is proposed as an intuitively intelligible representation of threshold levels.
- This new format has the potential to increase patient understanding and test acceptance.
Conclusions:
- Improving feedback, adaptation, and result display are key to enhancing computerized perimetry acceptance.
- The proposed symbol-size display offers a promising avenue for more intuitive visual field testing.
- Further research and validation of this novel display format are warranted.
