Vision & Eye Diseases
As you get older, your vision is often the first of the five senses to be affected. From 2000-2010, the number of people with AMD grew 18 percent, from 1.75 million to 2.07 million. AMD is the essentially any age-related vision disorder. A vision disorder is any issue that causes you to have trouble seeing, reading, or recognizing shapes or faces. Like any muscle, as we age, our eye muscles just aren’t as strong as they used to be, putting strain on the nerves and causing vision issues.
Other issues like cataracts and glaucoma also increase as we get older, so it’s important to identify the signs of a vision disorder, and how it can be treated.
Since the term vision disorder is so broad, there are a variety of symptoms to look out for. As you get older, you might not even know that you’re squinting or having trouble reading street signs. Make sure to be aware of these symptoms and see a doctor if you identify any of them.
Although there is no main cause of eye disorders, failing to take care of your eyes can have a huge impact later in life. Other factors like genetics and working environment can also play an important role when it comes to vision issues. Here are some of the most common causes of vision and eye disorders.
Doctors will usually go through your family background and perform a physical exam before performing any further tests. These questions will try to identify any issues that could cause your vision disorder, like work environment or a genetic disorder.
Snellen Test
A Snellen test is used to measure the visual acuity of the patient. The patient is asked to read the letters with each eye separately and both together. Ability to read the letters at each size determines the visual acuity. This is the typical eye exam that you see in most doctors’ offices and school nurses offices.
Visual Field Test
A visual test is used to measure a subject’s peripheral vision. A device is attached to the subject’s head and as lights are flashed in his or her peripheral vision, the subject is asked to press a button. This will allow the doctor to identify any blind spots or issues with the patient’s peripheral vision.
Tonometry
This exam uses special instruments to gauge the pressure of fluid behind the eyes. Too much or too little of fluid can create a variety of vision issues.
Cataract Surgery
This surgery will cut away the cataracts within the retina. Usually an artificial lens is placed within the eye as a replacement of the damaged and clouded lens. This, more often than not, restores the vision in the eye.
Glasses/Magnification Lenses
Most solutions for vision disorders will be some sort of prescription glasses. These will be tailored to meet the patient’s needs by conducting a vision exam. This exam will identify your prescription and will allow the optometrist to create the perfect lenses. They might also recommend magnification lenses to read smaller print.
Eye Drops
Eye drops can also be prescribed for those suffering from glaucoma or an eye infection. These will treat the eyes and allow the patients vision to clear.
