The Ultimate Optomotor Drum

Vision testing in freely moving animals

The OptoDrum measures the visual abilities of your laboratory rodents: in-vivo, non-invasively, quickly, and automated. Using the optomotor reflex, you can quantify visual acuity and contrast sensitivity. This can serve as a readout for many applications:

  • the efficacy of new ophthalmic drugs
  • the toxicity of chemical substances
  • the effects of neural injuries
  • the advancement of certain neurodegenerative diseases
