Top Causes of Blindness
1. Age-Related Macular Degeneration (AMD)
This eye disease is the leading cause of near-vision impairment in people over the age of 50. Patients living with AMD often lose part or all of their central vision, making it hard to perform daily tasks like driving, recognizing faces, and watching television.
A cataract occurs when the eye’s natural lens begins to cloud. While most people associate cataracts with advanced age, they can actually occur at any point in a person’s life, and for a variety of reasons. Risk factors for cataracts include genetics, age, radiation, trauma, and certain medications.
An estimated 17% of North Americans above the age of 40 have cataracts. Fortunately, they are easily removed through surgery. Left untreated, cataracts can eventually lead to blindness.
Glaucoma is a group of eye diseases caused by increased ocular pressure. The two most common forms are open-angle glaucoma and closed- angle glaucoma. Open-angle is more common and typically progresses silently over a long period of time. Closed-angle glaucoma is a more painful and acute form of the disease. All forms of glaucoma can eventually lead to blindness.
Early detection and treatment are key in preventing vision loss from glaucoma.
4. Diabetic Retinopathy (DR)
DR is a complication of diabetes that occurs when excess sugar in the blood damages the retina’s blood vessels. There are 4 stages of DR, with the first stages rarely presenting noticeable symptoms. In many cases the condition can be managed and treated by your eye doctor, especially if caught early on.
Regular dilated eye exams are crucial for patients with diabetes, as it helps ensure the earliest possible detection of DR.
- A: People often assume those who are blind are unable to see anything. The truth is that to be considered legally blind, a person’s eyesight must be 20/200 — in other words, you’d need to stand 20 feet away from an object that one with healthy vision could see at a distance of 200 feet away. Furthermore, those who are legally blind cannot correct their vision with glasses or contact lenses.
- A: Certain types of blindness are reversible. In cases of cataracts, corneal diseases, wet AMD and some instances of diabetic retinopathy, surgery, injections, and other treatments can return at least some sight to an individual who has experienced vision loss. On the other hand, diseases like glaucoma, retinitis pigmentosa, and dry age-related macular degeneration can cause irreversible vision loss.
