SEE HOW YOU’RE DRIVING

Unlike some other skills we use in our everyday lives, driving relies almost exclusively on our sense of sight. We feel our feet on the ground as we move about or know we are sitting in a chair; we are fully aware of our surroundings. This sensory information lets us know where the ground or chair is. When you are driving, there is no movement of your body. It is totally about your vision and how precisely your two eyes work together. If your eyes are not aligned perfectly, you may think an object is closer or farther away....

CATARACTS ARE A PART OF AGING

If you are coming in to your 40s, you may be noticing that your eyesight is changing. You have to strain a little to read, holding the book or newspaper farther away, or you find you need to wear bifocals. You may even notice a bit of clouding of the lens of your eyes. What is going on?   Your eyes, like many other parts of the body, are showing signs of aging. The Crystalline lens in your eye is becoming less flexible. This makes it more difficult for the lens to adjust and focus when you look from far to near.

Age takes its toll on all parts of the body, even the eyes. While conditions such as glaucoma are not necessarily inevitable as we get older, they are still possibilities that can change the way we see. It always pay to practice foresight – it just may save your eyesight.  Glaucoma is a rather complex disease. Simply put, it occurs when fluid pressure builds up in your eyes. Approximately two and a half quarts of fluid, called aqueous humor, pumps through the eyes every day, providing nutrients to the inside of the eyes.

GLAUCOMA

Age takes its toll on all parts of the body, even the eyes. While conditions such as glaucoma are not necessarily inevitable as we get older, they are still possibilities that can change the way we see. It always pay to practice foresight – it just may save your eyesight.


Glaucoma is a rather complex disease. Simply put, it occurs when fluid pressure builds up in your eyes. Approximately two and a half quarts of fluid, called aqueous humor, pumps through the eyes every day, providing nutrients to the inside of the eyes. This fluid is constantly being pumped in and out of your eyes. The pumping keeps the fluid clear and clean so you can see well through it. The way glaucoma works can be compared to a faucet and drain. As long as both parts are working fine and everything flows smoothly, you have no problem with backups or clogs. But sometimes the fluid gets blocked instead of flowing out of your eyes as normal. The blockage causes the pressure in your eyes, so the balance between inflow and outflow is important. A person can be born with glaucoma, but that only happens rarely. Usually the condition is related to age. Your risk of developing glaucoma rises a percentage point with each decade.


Unfortunately, glaucoma has no warning signals. The condition is painless and the pressure buildup that steals your eyesight is so slow and steady that most people have no idea they even have

glaucoma until they realize half their vision is gone. That is why glaucoma is called the “sneak thief of sight.” The sooner it is caught, the better able your eye doctor will be to keep it under control.


One of the first signs that you have glaucoma is a loss of peripheral or side vision. Visual field testing can check it. You may also see halos around lights or experience narrow or tunnel vision. Your eye doctor will check for glaucoma by dilating your eyes. This will give him a better view of your optic nerve. The pressure in the eyes often damages this nerve. The doctor will also perform a tonometry test to check the fluid pressure in your eyes. Treatment may include eye drops taken once or twice daily. These drops help relieve the pressure by either increasing the outflow of the aqueous humor or reducing its production. Another option is laser surgery, which can increase the flow of fluid from the eye. One microsurgery procedure is used to create a new channel to help drain the fluid and relieve the pressure in the eye. You should talk about your options with your eye doctor.


Glaucoma is essentially a neurode-generative disease. It cannot be cured and

lost vision cannot be restored. However, with proper treatment, the progress of the disease can be slowed down and the vision you still have can be saved. As with diabetes or high blood pressure, the ultimate goal with glaucoma is maintenance. Here, too, prevention is worth multiple pounds of cure.
