Macular degeneration is a condition in which the macula, the part of the retina responsible for central vision, deteriorates over time, leading to loss of central vision. Peripheral vision may remain intact, however. Cataracts involve clouding of the lens, which can cause blurry vision but typically do not affect peripheral vision. Glaucoma is a condition in which increased pressure in the eye damages the optic nerve, leading to loss of peripheral vision. Papilledema is swelling of the optic nerve head due to increased intracranial pressure, which can cause blurred vision and other visual disturbances, but does not typically cause loss of central vision.
