iPhone/iPad/iMacBooklet
Dark Adaptation
Soon available in the Apple Store

Foveal Dark Adaptation is measured.

Details:

MacDx (Professional Model, reimbursable) and MacHealth (Individual Mode, not reimbursable)

Either Model works on iPhone, iPad and MacBooklet.
MacDx measures white, red, green and blue light stress

MacHealth measures white light stress only.

The stress time is 30 seconds for MacHealth.

The stress time is 15, 30, 60 and 90 seconds for MacDx.

Studies:

#1.  A pilot practice study on patients was conducted which measured delay of light brightness in those with macular problems.

​#2. A published study of 6 normal subjects was conducted while stimulated with white light of the iPhone screen and showed the overall delay of 14.33 seconds and coefficient of variation of 15.9% as the mean in each eye.  Interestingly, the endpoint increased with the duration of the light stimulation with age and with subject's age.  Rapid testing the two eyes and testing in dark or semi dark room didn't influence the results. 

#3. Testing patients in a retinal surgeons office is being performed.
