Quantitative OMR Features & Benefits

The optomotor response (OMR) is a reflex used to assess visual function in rodents. The PhenoSys qOMR (mice) and the qOMR-XT (rats) are unique systems that objectively measure the OMR with minimal experimenter effort. It employs a virtual stimulation cylinder that continuously aligns with the animal’s head position. Based on real-time head tracking, quantitative OMR measurements automatically provide visual acuity and contrast sensitivity.

  • 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.

Hardware features

  • Calibrated 4 screen environment for presenting the virtual stimulation cylinder
  • Elevated central platform for placing the unrestrained animal
  • Top and bottom mirrors to create the illusion of infinite depth for optimized stimulation
  • IR-camera for automated head tracking independent of coat color
  • Adjustable IR-illumination
  • Anti-reflective (and protective) shields for the screens
  • Filter set for scotopic measurements
  • qOMR is suitable for adult mice
  • qOMR-XT is suitable for adult rats

Software Features

  • Video-based real-time tracking of head movement is used for both:
    • 1. Continuous automated position-adjustment of the virtual cylinder to the animal´s head position.
    • 2. Evaluation of head movement synchronous to the stimulation for a quantitative measure of the optomotor response. This analysis is fully automated.
  • Batch run option with multiple stimulation protocols.
