I am in my 30's and have a -8 vision in both eyes with no previous history of retina holes, tears, or retinal detachments at this time. I am planning to travel to Rocky Mountain National Park later this summer for several days and noticed the elevation there is around 8,000 feet. I currently live basically at sea level.
I found a couple medical articles mentioning retinal vascular changes that can occur when exposed to lower oxygen levels at higher elevations:

http://retinatoday.com/2013/08/exposure-to-high-altitude-may-cause-retinal-vessel-leakage
My concern is retinal neovascularization occurring around the macula and causing irreversible damage since there's less oxygen. Has anyone traveled to higher elevations before and experienced any retinal issues? Is it safe to travel to higher elevations for those with a previous history of retinal problems?
