RICHMOND HRR PSEUDO RED/GREEN ISOCHROMATIC COLOR TEST

SKU: CTRI-01-005
Description

[13396RGC]
HRR 4TH Edition Subsets provide separate tests which are a subset of the complete HRR 4th Edition. One subset permits for testing of Red and Green congenital defects. The other subset version allows testing for Acquired defects (Tritan) by providing the Blue and Yellow HRR color plates. This Blue/Yellow Subset is an easy way to complement an Ishihara test (which tests for congenital color vision deficiencies only) to insure you have capability to test for Acquired defects as well. Each Subset contains 2 demonstration plates to help patients understand the test procedure. Each is spiral bound with an integral cover, instructions, page tabs and a laminated score sheet. The sum of these two books has all the plates contained in the full HRR Pseudoisochromatic Book. The advantages to using the HRR Subset Books are: Maintains test quality equal to the HRR 4th Edition Pseudoisochromatic color blindness Test quality Uses methods which avoid errors due to illiteracy and language problems (uses symbols instead of numbers.) Provides "mild, medium, and strong" calibration of the patient's color vision. Permits to upgrade to add Acquired color testing capability without buying an entire new book. New coil binding permits complete fold over for presentation one page at a time Subset includes 14 plates plus 2 demonstration plates for a total of 16 plates
