I don't know how it works now, but in my case the Doctor had nothing to do with it. It's obvious I'm blind since I use a cane. I showed the person in charge of accommodations how bulky a braille printer along with all its paper is, and the noise it makes that's loud enough to wake anyone who may be trying to sleep in the same room. They granted me the accommodation since I had to use braille for math, physics, chemistry, and computer science. I think in some ways it's easier having an obvious disability. You can't hide it, and the only time people don't believe your blind when using a cane is at the bar on Halloween.
