my daughter is 21, she has EDS,POTS and has had double vision since she was 6, she has had 4 eye operations over the years with poor results. She has double vision with both eyes, with one eye covered she has single vision for a short period of time. I have always thought her vision and EDS is connected.She has had toxin injections, patches, with no success. She is under the care of prof Grahame at UCL for her EDS, he has said its not common to have double vision with EDS,Great Ormond st and Moorfields also thought her health issues were not connected. EDS is a connective tissue disorder,eyes are 80% connective tissue, I’m only a mum, what do i know!.
