Yes, there is 'open angle ' glaucoma which I have and closed or narrow angle.
I'm not understanding the part about the 'fiber in the eye 'not holding the lens' Are you talking about cataract surgery ? That's the only instance where a lens is replaced, unless you are talking about full cornea transplant.
As far as glaucoma goes, I have drainage shunts implanted in both eyes.. and again, as far as I know, surgery can be done for closed angle as well.. If I were he, I'd get a second opinion.
Something doesn't sound right here.
My ophthalmologist is the official Dr for the Jacksonville Jaguars.( don't laugh )
Here's this
"What is LPI?
LPI attempts to "open" a "narrow" angle. Since the angle is the part of the eye that drains fluid FROM the eye, narrowing of the angle can put the eye at risk for an acute attack of angle closure glaucoma. During the LPI, a laser is used to make a small opening in the peripheral iris (the colored part of the eye). This changes the fluid dynamics in the eye and "opens" the angle. If a patient already has acute angle closure glaucoma, the small opening that is made in the peripheral iris allows fluid to drain more normally and also lowers the eye pressure."
Narrow or closed angle glaucoma is much more dangerous and acts much more quickly in vision loss. Your brother should find another Dr And SOON. Apparently his present Dr doesn't know what he's talking about.
ooops, I just lost the link, but you can research surgical options for narrow angle glaucoma. There are options..
I'm on my way to the eye Dr too, gotta run.
