QUANTITATIVE omr The qualitative optomotor response is a unique system that automatically measures OMR with minimal experimenter effort. Easily combinable with electrophysiology setups, quantitative OMR measurements run fully automatically and objectively.

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
