Hi, @lupita1407 - welcome to Mayo Clinic Connect. Not being able to walk without a walker sounds challenging. It sounds as though you are being an excellent advocate for your wife.

Hoping that @flo1957 @steph73 @menville @howardjames may have some input for you on studies they have read about or participated in. @johnbishop also may have some insight on relevant studies.

How is the vertical double vision impacting your wife's day-to-day life presently?
