had a guy want to breed his bitch to my stud dog. CERF says "normal" but in the comments section it says PTVL, what is that? I never had that comment?

persistent tunica vasculosa lentis (PTVL)

Looks like it's congenital, but you can contact CERF to find out the status in Labradors of this condition.

I got a CERF number, but don't know what this condition is
