However, about 50% of them don’t yet know that they have the disease because their symptoms have not yet become problematic, or because they’ve skipped regular eye exams to screen for the disease. The National Eye Institute estimates that approximately 40-45% percent of Americans diagnosed with diabetes have diabetic retinopathy to some degree. As damage progresses, changes to vision, including peripheral vision loss, become more evident. High blood sugar levels from diabetes can damage the small blood vessels in the retina, which is the area of the eye that senses light. Over time, this optic nerve damage can cause peripheral vision loss, and if left untreated, can cause complete vision loss over time.īecause the disease has no early signs or symptoms until vision loss begins, glaucoma is often referred to as the “silent thief of sight.” Once the disease has advanced to the point that your vision is damaged, it’s usually too late to prevent or reverse peripheral vision loss. The second most common cause of blindness in the U.S, glaucoma causes damage to the optic nerve, which connects the eyeball to the brain. The American Academy of Ophthalmology notes that peripheral vision loss is often caused by four conditions: It can affect either one of your eyes or both. For example, people suffering from migraine headaches sometimes suffer from tunnel vision temporarily. While tunnel vision is usually permanent, there are also certain situations where it affects people temporarily. A damaged optic nerve, retina or affected areas of the brain responsible for processing visual input can lead you to peripheral vision loss. You can lose peripheral vision at any age, but your risk increases with age since the underlying conditions linked to various eye conditions also increase with age. Many patients with peripheral vision loss also have impaired night vision. People with peripheral vision loss are often more prone to trip over objects in their path or bump into other people. Peripheral vision loss can cause difficulties with spatial orientation and mobility. The loss of peripheral vision is often referred to as tunnel vision, and it can indeed make you feel like you’re in a tunnel or that the world is closing in around you. Your peripheral vision, also known as side vision, gives you the ability to see to the sides, above, and below a central point of focus straight ahead of you, without turning your head sideways or moving your eyes side-to-side or up and down. ![]()
