Question: What is ophthalmoscopy and how is it used to diagnose glaucoma?
Answer: Ophthalmoscopy refers to the microscopic examination of the back of the eye. It can be used to diagnose not just glaucoma but any retinal diseases as well. In glaucoma we use it to take a very detailed examination of the optic nerve. That is the anatomic site of damage from elevated intraocular pressure. We look for pathologic changes in the optic nerve that are typical for glaucoma. So it's used not only for the diagnosis but also for the management of glaucoma, because if the disease progresses you'll see those changes in the optic nerve.
