Warning Signs of Eye Trouble
Blurry vision, spots, glare at night -- these are common eye complaints. Each could be a harmless annoyance or an early sign of disease. It isn’t always easy to tell the difference. Visit Laser Vision Centre promptly if you notice any changes in your vision.
You can’t feel it, but this disease damages your optic nerve. You may not have any symptoms until you lose your central vision. Your side vision will go first. That’s why you need regular eye exams every 1-2 years, especially after you turn 40.Doctors can treat glaucoma with medications or surgery.
Glaucoma: What happens
Your eye is filled with fluid. Sometimes too much of it builds up and raises pressure inside your eye. This can damage your optic nerve, a bundle of nerve fibers that carries information to your brain. Without treatment, glaucoma can cause total blindness.
The bright yellow circle shows an optic nerve head damaged by glaucoma. The dark central area is the macula, which controls your finely-detailed central vision. Learn more about Glaucoma here.
Macular Degeneration: View
Age-related macular degeneration (AMD) damages and then destroys your central vision, making it hard to read or drive. Symptoms can include a central blurry spot or straight lines that appear wavy. You're more likely to have it if you are older than 60, smoke, have high blood pressure, are obese, are female, or have a family history of the condition. See your eye doctor regularly to check for AMD. Prompt treatment can help slow vision loss.
Macular Degeneration: What happens
AMD affects the central part of your retina, called the macula. There are two types:
Dry: Doctors often see yellow deposits called drusen in the macula. As it worsens, the macular tissue breaks down. That slows the delivery of images to your brain.
Wet: Abnormal blood vessels grow in your eye. They leak blood and fluid (shown here), which causes scars and further damages the macula.
Both types leave you with a central blind spot.
Macular Degeneration: Test
Cover one eye and stare at the center dot in this Amsler grid from a distance of 12 to 15 inches. (You can wear your reading glasses.) Do you see wavy, broken, or blurry lines? Are any areas warped or just plain gone? Repeat for your other eye. Although no self-test can take the place of an eye exam, this grid is used to help spot early symptoms of AMD.
