Question: what is the difference between chronic open-angle glaucoma and acute angle-closure glaucoma?
Answer: In open-angle glaucoma, the iris is in the right position, and the uveoscleral drainage canals are clear. But the trabecular meshwork isn't draining properly. In closed-angle glaucoma, the iris is squeezed against the cornea, blocking the uveoscleral drains and the trabecular meshwork.
