OptoDrum is an easy to use replacement for a bulky optokinetic drum or a fraying cloth tape to elicit optokinetic nystagmus for evaluation of neurological, otological, and opthalmological disorders.   Simply place the iPhone with a moving pattern in front of a patient’s eye to elicit the response.  The stripe pattern, width, and speed are easily adjustable. • OptoDrum provides five patterns: black stripes, red stripes, mixed colors, symbols, and animals. • Drag a finger up or down the screen to make the pattern move at the speed of your finger. • Double tap the moving pattern to make it stop. • Pinch or zoom the pattern with two fingers to narrow or widen the pattern. • A left or right finger swipe switches a stopped pattern to the next one in rotation.



  • Does the job

    By Functional Neurology
    It's a little tricky but with enough pinching, tapping the top where the icon bar appears, and sliding down on the screen you can change settings. Direction is changed by catching the movement to a stop and dragging slowly in reverse. It works better with young pediatrics than traditional methods of kinetic assessment and therapy, so worth $5!
  • Doesn't work as described

    By mysteryalias
    My first use of the darned thing and it won't stop on double tap as directed. It will change directions but not stop. Five bucks for a crap app. How about .99? At least I won't feel ripped off for buying an app that doesn't work from the start. Not to mention that it's just rolling bars! Haven't found color options yet, so that may not work either. Don't buy.
  • Glitches

    Cannot change icons or freeze movement once started in current version ! I regret updating !
  • Won't load onto my iPad

    By Madelle
    Only loads on my iPhone. What a waste of Money
  • New version (1.3.2)

    By UM-SL
    The freezing issue in fact has been fixed. I've tried it on both the iPad and iPhone and it consistently has worked very well.
  • Turbo Drum

    By Xlimey
    I too had the same problem with Turbo Drum as Camelottt but had she(?) contacted their help desk she would probably have found that her iPad IOS was out of date. Upgrading it to 5.1 was easier said than done and needed a final step of erasing TD then reloading it in order to reset the app directory. Doing this also fixed all the other loaded apps which had stopped working along with the IOS upgrade. Turbo Drum now works as described by the author and is an invaluable aid to neurological disorders.

    I want a refund! Unable to get this app to work properly. Sticks, does not move, continually rebooting. Support info does not alter problems!
  • Not worth spending money on

    By Prambanan
    Some Apps have thousands of hours of programming. This App is maybe 2 hours and cost $5!!! Should 1000% be free. Its rudimentary.

    By Ugbugcheese
    My dr. also suggested this app and you can't get off one page. this should be a free app, not $5s.
  • Hate this ap

    By mjchap
    My Dr asked me to use this ap. I hate it. You can never get to the correct page. I can spend half an hr just trying to get of one page. the MOST AGGRAVATING AP EVER! And I paid for it!! Err.
