Marteniuc it will be easier for people to help you if you respond to the queries. As per Webby737's query was your initial test the Ishiara plates?
Regarding the 2nd test at the end of February did your Optometrist refuse to examine you based on your Optometry results from the 1st test? If you took and failed the Ishiara you should have been given the option of the CAD test, if you took and failed the CAD test then that is a different story. You stated in your first post that you have a deutan colour blindness which begs me to think you may have already had the CAD.
