Was on eye drops for glucoma. One morning when I wanted to read the
morning paper, my eyes were clouded up. Could not even read the head lines.
Cataracks, not from the eye drops. Surgery had new lenses inserted. Now see
better then I have for many years. still tking drops, ocasionaly.

 You say, "The doc says the nerve damage looks like glaucoma and wants to do a
trab."  I'd say unless you have some reason to doubt the doc, get the trab, and
if you do have such doubts, get yourself to a glaucoma specialist for a second
opinion.  Just don't put it off!
    Best of luck to you,

If it's taking you that many meds to achieve a high-normal IOP, then
it IS likely that you developed optic nerve damage...the question is
was it there before and just missed?  None of us will ever know.
Other causes of sudden vision loss include a closed off artery or vein
feeding the retina (called a central retinal artery occlusion or vein
occlusion), a stroke to the optic nerve itself, called anterior
ischemic optic neuropathy.  Less likely causes would include
cataracts, which often develop slowly, or retinal detachments, which
are seldom associated with high IOP.  You might consider a second
opinion if you are concerned.  Hope that helps.
