I wish JustK was right, but I have personal experience with 2 individuals who are limited in what they can do by thier bodily limitations. My late husband could not serve in the military due to juvenile diabetes, and then could no longer work in his chosen career (medical technologist) due to pathological exposure after he recieved kidney/pancreas transplants. My second husband was unable to pursue his dreams of being an astronaut due to vision issues; he was near-sighted. In this country, we want to believe merit and hard work are all that matters...and I wish I still believed that!
Having said all that, most medical schools require you to be able to perform certain skills to certain standards. Towards that end many have created technical standards. Often these standards will include an option of 'with reasonable accomodations' but I do not know what is reasonable. I do think you could contact the vet schools you are interested in anonymously and ask about this. I believe you will get answers and explanations.
You might also see if you can find a doctor who has a similar disability, and find out what they know. If someone has already achieved it, it can make your path a bit easier (gives you a reference point, may provide suggestions on accomodations that you might not have thought of, etc.)
