Did you know it is possible that even toward the “end-stage” of glaucoma that a person’s vision can be 20/20 on the eye chart? It’s true, but 20/20 vision in this scenario is only seen through what appears like looking through a paper towel roll, where the entire side vision is missing, 360 degrees, all the way around.
Glaucoma typically develops very slowly over the years and tends to creep in little-by-little, year-by-year. It results from damage to the optic nerve (the cable that connects the eye to the vision area of our brains), and unfortunately, once the nerve is damaged, there is no way to repair or replace it. Therefore the key is prevention, typically via laser, microsurgical, or daily eye drop treatment.
