HRR Calculator app for iPhone and iPad

You can now use your iPad or iPhone to enter patient results by touch screen when
administering the HRR Pseudoisochromatic Plate test. These results are then interpreted into
a recommended diagnosis based on the rules from the original HRR Instructions. The patient
file can be immediately updated via e-mail or PDF. Patient privacy is maintained by password
protected entry. Since the actual HRR Plates are used by the patient, the integrity of the color test
results is maintained.

Testing results can be entered based on binocular or monocular (recommended) examination.
The name of the test administrator is also logged for future reference. Output choices support
presentation of the results for occupational testing. Further, the ability to compare the patient’s
HRR results over time is especially important with Tritan errors resulting from drug toxicity.

The app also includes a copy of the Color Vision Tutorial which highlights the growing importance
of color vision testing in terms of occupational applications and acquired color deficiencies such
as those resulting from a long list of prescription and OTC drugs.
