AMEand PPL -I think you will find that the UK standards have changed. Visual acuity standards have changed. Pilots are permitted to fly following myocardial infarction, coronary artery bypass grafting, or even heart transplantation. EEGs are no longer required for initial screening as the evidence was not there for them (you remember evidence based medicine don't you). There is a lot of work being done by the CAA medical authorities regarding colour vision requirements as well. The "1 percent rule" is also under review. Just because a rule is long-standing, does not mean that it is still applicable or best practice. If it was, we would still be using leeches.
Your constant denigration of the Australian authorities, just because the way they do things is different to what you learned "back in the day" is offensive, and reeks of ignorance and snobbery. The Australian authorities do not allow the certification of epileptic nor blind pilots. However, if they did, it would be done on a sound analysis of the current evidence, the risks of sudden or subtle incapacitation, and with wide consultation. Decisions are not made on the mindless basis of "that's the way it's always been" or "we must do what the Brits do because they are the only ones who know what they are doing".
