I never said any Optamologist was wrong, and am willing to accept I am wrong, If I am told different.

You haven't told me anything different, you've just said I am wrong and I asked you to enlighten me. I'm not unwilling to accept anyone elses views, except you haven't given one, except to say I'm wrong !

And if that's the case, regardless of Mals or any other breed where the DNA marker for late onset isn't know, why therefore will no-one breed from a dog that has it, ??

I refer you to my previous post:

You haven't enlightened me at all, that is stating the obvious.

They dont yet have the DNA marker for late onset, therefore Opthalmologists call it Hereditary Cataracts just in case and recommend that dogs with it dont be bred from.

They dont yet know whether it is hereditary or not, so where am I wrong ?

The whole point of DNA testing is that you can use affecteds and carriers in breeding programs without producing affected dogs. So to me it isn't whether it has cataracts or not but is the dog of suitable merit or of a rare line gene pool wise then it can be bred from.

Where have you read that all senile onset (or late onset) cataracts are hereditary?

Maybe I assumed wrongly that all breeds carried the same ethics as my own, and that is that ANY dog that has been tested and found to have Cataracts not be bred from full stop.

MY previous quote :

I didn't say I read it anywhere.

I've been to a fair few eye testings with a very well respected long standing examiner, and I also sat in on a telephone conversation he had with his own University mentor on the subject, who stated the above.

Well it would help if people adhered to the ethics in the first place What you have stated is certainly true for hereditary cataracts.

Explain why you think they shouldn't be bred from.

Interesting - may I ask who this opthamologist is? Can they not provide you with the literature you seek?
