Cardiff Hospital goes for YANG
February 25, 2008
The YANG now comes complete with a whole array of paediatric visual acuity tests from Kays tests through to numbers, tumbling E's, Landolt C's and other picture tests.
The entire suit of tests for the 'younger' patient is very comprehensive with distance stereo acuity, Worth 4 dot, contrast testing, colour vision and a REAL fixation that works with Maddox rod and Bagolini lenses.
Remember only the YANG is colour and light calibrated and has a in-built photodetector that refines output screen luminance to account for variations in ambient room illumination - so you get total consistency in VA measurement.
