Measure OMR with minimal experimenter effort
Optomotor response (OMR) is a reflex used to assess vision in mice. In order to evoke OMR, a mouse watches a rotating cylinder with a striped pattern. Stimulus correlated head movements are quantified to determine visual thresholds. The qOMR (quantitative OMR) is a unique system that automatically measures OMR with minimal experimenter effort. It uses a virtual stimulation sphere that constantly aligns with the animal´s head position. Based on real-time head tracking quantitative OMR measurements run fully automatically and objectively.
Quantitative optomotor response (OMR) features & benefits
- Simple, robust, and non-invasive test to examine vision in rodents
- Fully automated measurement and analysis: no manual positioning of the stimulus, no specially trained experimenter required, time and cost effective, and unbiased
- As a reflex, OMR measurements do not require animal training
- Freely behaving animals, no surgery, no fixation
- Flexible, user-friendly experimental design and data handling.
- Calibrated 4 screen environment for presenting the virtual stimulation sphere
- Elevated central platform for placing the unrestrained animal
- Top and bottom mirror to create an illusion of infinite depth
- IR-camera with adjustable IR-illumination for automated head tracking.
qOMR applications
1. Investigation of various aspects of vision in mice and other rodents
- Visual acuity
- Contrast sensitivity
- Spectral sensitivity
- Temporal sensitivity
2. Characterisation or preclinical testing in relevant disease models, for example
- Glaucoma
- Retinal degeneration
- Diabetes
- Aging
3. Examination of axonal regeneration
