Summary
This study explored how body position affects visual field testing. A new swivel arm perimeter was developed, showing promising initial results for improved visual field assessments.
Area of Science:
- Ophthalmology
- Medical Devices
- Visual Science
Background:
- Visual field testing is crucial for diagnosing and monitoring various eye conditions.
- Standard perimetry may be influenced by patient positioning.
- A need exists for adaptable perimetry systems.
Purpose of the Study:
- To investigate the impact of body position on visual field test outcomes.
- To introduce a novel 'swivel arm perimeter' for enhanced perimetry flexibility.
Main Methods:
- A modified Octopus 1-2-3 perimeter was utilized.
- The measuring unit was detached and mounted on a multi-directional swivel arm.
- The device allowed for movement in all directions.
Main Results:
- Initial results suggest the swivel arm perimeter is a viable development.
- The device demonstrated potential for adapting to different body positions during testing.
Conclusions:
- The development of the swivel arm perimeter was deemed worthwhile.
- This innovative device may offer advantages in visual field testing accuracy and patient comfort.
