Technologies

Ophthalmologists at UC San Diego have developed a tablet-based, cloud-enabled method of measuring spatial and temporal aspects of visual and cognitive performance. This technology is the first comprehensive suite of visual impairment tests that can be implemented on a single portable device (e.g. iPad). Existing traditional tests are administered by a variety of different devices, wall and hand-held charts.

This mobile visual performance profiling (MVP2) technology combines several visual performance tests into a single portable device that accelerates testing time, data entry, and analysis.

Created to assess a wide variety of conditions in the eye or brain that impair vision, the mVP2 enhances and improves the sensitivity of vision testing by combining different domains of vision (e.g., contrast with concomitant visual processing speed) in novel ways.

The mVP2 includes a comprehensive test suite:
1. Visual Acuity (VA);
2. Contrast Acuity (CA);
3. Contrast Sensitivity (CS);
4. Visual Processing Speed (VPS) at different contrast levels;
5. Divided Attention (DA) at different contrast levels;
6. Motion Detection;
7. Stereo-acuity;
8. Hue Discrimination/Matching;
9. Pursuits, saccades and eye movements;
10. RT/CRT;
11. Visual search- Trails A/B;
12. Visual Memory-BVRT.

Traditional vision tests are not typically integrated into a single testing device, resulting in medical assistants or clinicians using multiple charts or devices in multiple locations. Test data is recorded on paper or automatically by a device that is not integrated with other devices. Meta-data of tests are usually not available for immediate interpretation and decision-making. Mobile tablets, smart phones, and laptop computer platforms will offer mobility, accessibility, and affordability that are key indicators of quality medicine. They will make it easier to deliver cost-effective care that is comprehensive and coordinated by ensuring its continuity. Current methods are also generally not portable.
