Also known as "the silent thief of vision" due to its lack of symptoms
until end stages, glaucoma causes a painless loss of vision, starting with
the peripheral vision. It is caused by an increase in the pressure inside
the eye causing compression and subsequent damage to the optic
nerve - the nerve that connects the eye to the brain. Left untreated, this
will lead to blindness. If detected early, any damage can be slowed or
stopped using either eye drops or surgical methods in advanced cases.
For this reason, it is recommended to have an eye exam every 12-24
Vision loss simulation due to glaucoma. Note that this type of vision loss will only be noticeable in the end stages of glaucoma. Eventually, without treatment, even the central vision will be lost.
