Optokinetic Drums

Definition : Diagnostic ophthalmic devices designed to elicit and evaluate the regular, involuntary movement of the eyeball (i.e., nystagmus). The devices are typically drum-like cylinders covered with uniform white and dark vertical stripes with a handle. The rotation of the devices can induce optokinetic nystagmus, and then the examiner observes the patient's abnormal eye responses. Optokinetic drums are used to diagnose a variety of visual problems.
