During my first two years as a graduate student, the readers, instructors, and staff working with me would all meet together once a semester. We held these meetings at the end of the semester so that the instructors for the following semester could talk to instructors of the current semester. This allowed advice to be shared and progress to be built upon in a clean and orderly manner.
Meetings like these help educate an entire faculty on how to best educate visually-impaired students, rather than each professor and student having to figure it out case-by-case. I would highly recommend holding meetings like these to improve and standardize support.
