Good News!
CASA called me back and confirmed I CAN hold ATPL as a monocular pilot.
It is colour blindness that prevents you holding ATPL.
I have started wearing the patch again - gives me really bad headaches though trying to process info with the weaker eye because even though everything is in focus it is like your brain gets confused trying to read small print etc. I will see how improved things get after a month of patching while in the house. I think I wore the patch for half a day or so and when I took the patch off, whoa... strange sensation. It's like my brain is overloading on visual information seeing things completely different or something. So the patching must be having some effect.
I try to play computer games while the eye is patched since it forces my brain to process movement and patterns. I fly GA aircraft (with large aircraft there is too much necessity to read instruments with fine print on them - GA I can fly looking out of the plane only) on flight sim and racing cars on rFactor. I am sure there are exercises that are specific to this though.
