Glaucoma is a condition in which the retina and the optic nerve become damaged as a result of gradual fluid pressure buildup in one or both eyes, explains Everyday Health. The damage eventually causes a gradual loss of peripheral vision, a condition that is irreversible. To prevent vision loss due to glaucoma, it is advisable to undergo routine eye examinations so that the condition can be diagnosed and addressed in time. Some remedies that are applicable in the management of this condition include eye surgery and prescription eye drops.

Macular degeneration is an eye condition in which the macula deteriorates with time, disrupting the central vision of an individual, says Everyday Health. The deterioration causes blurred vision and blind spots. The condition commonly affects older adults and has no cure. However, its development can be slowed down with treatments such as combination vitamin therapy, photodynamic therapy and laser surgery.

Diabetic retinopathy is a condition that results from systemic damage caused by diabetes, notes Everyday Health. In this condition, the blood vessels that serve the retina become damaged, leading to retinal bleeding and damage, and eventual vision loss.
