For some places, there are. I'm not sure where you are from (you mentioned SSDI, so I assume you are from the US). You should contact your state or local vision rehabilitation agency or Social Security office to find out more and fill the paperwork in.

You should also contact your local vision rehabilitation agency to start getting rehabilitation training. The training is a bit easier with when you have some vision. Additionally, the workers can probably help you out with going through some of the steps, and some agencies also have workplace programs as well .
