You are caring for a client with open-angle glaucoma. You know that this disease causes which of the following? Select all that apply

B) Edema of the lens
C) Degeneration of the optic nerve
D) Edema of the cornea
E) Atrophy of nerve fibers in the peripheral areas of the retina
C, D, E
Feedback:
Open-angle glaucoma occurs when structures in the drainage system (i.e., trabecular meshwork and canal of Schlemm) degenerate, and the exit channels for aqueous fluid become blocked. As the IOP rises, it causes edema of the cornea, atrophy of nerve fibers in the peripheral areas of the retina, and degeneration of the optic nerve. This makes options A and B incorrect.
