Amanda Keeley from Exile Books about zines by people who are blind or visually impaired, and I thought that people beyond Amanda might be interested in the answer.
Mad Mulatta pages from Nice Zines blog
The following include zines by blind/visually impaired people, as well as partners of the blind/visually impaired:
Blind date & cyborg sweetie
Life, death, love & "all of the above"
Amanda's research is for developing a zine workshop that privileges people who are blind and visually impaired- in progress, which she is working on for Miami Lighthouse for the Blind and History Miami Museum.
