Retina and Vitreous
The retina is a light-sensitive layer of tissue, lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina (through the cornea and lens), which serves much the same function as film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve.
Age-related macular degeneration (AMD) is the leading cause of vision loss in adults after age 50. If you have vision loss from AMD, you can continue with many of the activities you do now.
Diabetic retinopathy is the leading cause of blindness in adults. Taking care of your eyes helps reduce your risk of vision loss. Treatment procedures such as laser treatment and vitrectomy may help slow the progress of diabetic retinopathy.
Retinal tears and detachments can occur as a natural part of aging or through injury or other issue. These can often be repaired with a surgical procedure. Your ophthalmologist will discuss available procedures with you, including the risks and benefits of each.
