About this app

OptoDrum is an easy to use replacement for a bulky optokinetic drum or a fraying cloth tape to elicit optokinetic nystagmus, OPK or OKN, 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 stripes or symbols.

• A left or right finger swipe switches a stopped pattern to the next one in rotation.

Really easy to use and very effective. I've tried several OKN apps and this is by far the simplest and the best. Change the speed you drag your finger across the even and it easily changes the speed the bars move. I can get it to any speed I want it at. Easy to go from black&white to red&white to shapes to kids images.

its a pain to get the speed set just right - wish there was a way to easily adjust it. itd also be great to have a timer feature where it stops after a set amount of time. if i hadnt already paid for the app, id just use one of the free ones. sorry to write such a gripey review ... i just get frustrated almost every time i use it!
