TranscriptJullia Rosdahl, MD, PhD: Glaucoma is a disease of the optic nerve. It's just when we look inside the eye and see that cupping of the nerve developing that we know that there's glaucoma. Then there's another type of glaucoma that's called angle-closure glaucoma, and that glaucoma does have some really important signs and symptoms. The holy grail for glaucoma is some way to actually regenerate and protect the optic nerve. But, yeah, the holy grail would be to stop glaucoma despite pressure and then eventually try to regenerate the damaged optic nerve.
