Abstract
In order to study the deuteranopic convergence points we compared the patterns of simulated panel D-15 tests with the actual data from 73 cases of deuteranopia.
It was found that 39 of the 73 cases matched one of the four simulation patterns perfectly while another 25 cases showed similar patterns. Of these 64 cases, 9 cases matched the simulated pattern obtained when the x chromaticity coordinates were from 1.1810 to 1.4319, 42 cases when they were from 1.4320 to 2.2588, 7 cases when they were from 2.2589 to 3.6255 and 6 cases when they were from 3.6258 to 4.6572.
These results confirmed that there is considerable variation between individuals in the convergence points of deuteranopes and supported the theory that the confusion lines meet at a finite point rather than running parallel.
