As already mentioned earlier you could consider getting an FAA (US) Medical - there are FAA licensed aviation medical examiners (AMEs) here in Europe. But it doesn't really help you regarding the EASA regulations/requirements.
If I'd be you I'd go and talk to a (nearby) EASA Doc and see what he says. It's always good to get a second opinion! I know that the head physician of an AMC (Aero Medical Center) can grant a medical based on a single case decision.
Seems that my right eye drift is out of the parameters, no idea what it means,...
If I'm not mistaken, you're crossed eyed, also called "to squint"?! Which basically means that you are probably lacking depth perception (no 3D vision). But as long as you don't have any issues with seeing double images (occasionally) it should be possible to obtain an EASA medical based on a single case decision.
I was told that there is a very good specialist regarding vision questions in the Netherlands at the Breda International Airport AMC. Here's the link.

Good luck!
