What Glaucoma Does to the Eyes

If your ophthalmologist near Chicago has diagnosed you with glaucoma , you may be wondering about the nature of this condition and how it will affect your vision and eye care. Different patients can experience glaucoma in different ways. In most cases, this disease affects peripheral vision first. As glaucoma progresses, it can cause you to experience tunnel vision as your peripheral vision continues to deteriorate. While some people maintain their central vision, this can also be damaged by glaucoma.

Eye doctors aren’t certain about why glaucoma causes damage to the optic nerve but for many patients, an increase in pressure in the eye seems to be involved. Your eyes produce a watery fluid called aqueous humor that, in healthy eyes, drains out and into the bloodstream. Because of a malfunctioning drainage system, the fluid fails to drain properly in some individuals, resulting in an increase of pressure in the eye. Some ophthalmologists believe that this condition may be the cause of the optic nerve damage and resulting vision loss that occurs in glaucoma patients.

What to Know About Age-Related Macular Degeneration

Age-related macular degeneration (AMD) is one of the most common causes of vision loss in Americans over 50 years of age and is frequently treated by eye doctors in Chicago. If you’ve been diagnosed with this condition or think that you may be at risk, read on to learn more about AMD. vision - loss

Types of AMD

Age-related macular degeneration affects the macula, which is at the back of the eye in the center of the retina. AMD can cause slow or rapid vision loss but rarely leads to total blindness. Dry AMD usually progresses slowly and is the most common form of this condition. This type of AMD stops the flow of nutrients to the cells in the macula which process light, resulting in cell death. Wet AMD tends to progress quickly and results in more serious vision loss. With this type of AMD, abnormal blood cells grow beneath the retina and break open, resulting in vision impairment.

Symptoms of AMD

It’s possible for the signs of AMD to manifest only once the disease has progressed. AMD sufferers can experience symptoms that include difficulty seeing in low light, seeing straight lines as blurry or wavy, trouble seeing in the center of vision, and changes in the appearance of colors. Visit an eye care specialist if you experience any of these symptoms.

Treatment for AMD

For patients diagnosed with dry AMD, vitamin supplementation is the current form of treatment. Research has shown that in certain combinations, vitamins can slow AMD’s progression in some patients. Treatment for wet AMD focuses on preventing the growth and decreasing the leakage from the abnormal blood vessels. Laser procedures are sometimes used, but anti-vascular endothelial growth factor drugs are the standard treatment. These medications are injected into the eye by an ophthalmologist. The eye is numbed beforehand, and the injections must be administered several times over the period of treatment. Your eye doctor may also recommend that you speak with your primary care physician about developing an exercise plan and making dietary changes that support a healthy lifestyle.

Understanding Dry Eye Syndrome

Dry eye syndrome is a condition frequently treated by eye doctors. If you are looking for an ophthalmologist to receive dry eye treatment near Chicago, you may have questions about this disorder. Watch this video to understand the nature of dry eye syndrome.

Your eyes have three layers of tears. The reason that most people develop dry eyes is the deterioration of the mucin cells, which make up the bottom tear layer. As you age, these cells can begin to fail, resulting in a reduction of your tear production and a feeling of dryness in your eyes. Eye doctors often recommend artificial tears to provide dry eye treatment for mild cases of this condition.

Taking Care of Your Child’s Vision

Types of Eye Care Specialists

There are a variety of eye care professionals that your child may need to see. Optometrists offer primary vision care and can perform eye examinations to determine if your child needs glasses or is suffering from an eye disease. Opticians specialize in fitting and adjusting eyeglasses. Ophthalmologists are medical doctors who provide comprehensive eye care, including surgery and practicing medicine. Finally, pediatric ophthalmologists are eye doctors who have undergone additional training to diagnose and treat problems that can affect children’s eyes.

Sources of Childhood Eye Care

Throughout her childhood, your child should periodically have her eyes examined. Newborns typically have their eyes checked by a doctor while in the hospital nursery as part of a general health examination. Your child’s pediatrician or family doctor should perform eye health screenings as she grows up and if irregularities are detected, direct you to see an eye doctor. For children that already wear corrective lenses, visits to an eye doctor should be scheduled once per year so their eyes can be monitored for changes and their eyewear can be updated accordingly.

Signs of Childhood Eye Problems

Besides having a doctor look at your child’s eyes, you can also take care of her vision by knowing how to spot eye problems. If you notice that your child’s eyes are extremely sensitive to light or are chronically watery or red, schedule an eye doctor appointment. Other indicators of an eye problem include poor visual tracking, poor focusing, a whitened pupil, constant eye rubbing, and abnormal eye movement or alignment after six months of age. Once your child is of school age, there are behaviors to watch for that can indicate that she is struggling to see properly. These can include sitting close to the TV, squinting, having difficulty reading, struggling to see distant objects, and having trouble reading the blackboard at school.

Sunglasses: More than Just Fashion

July is UV Safety Month, which serves to remind individuals of the importance of protecting themselves from the sun’s harmful rays. Ultraviolet (UV) radiation is a type of energy transmitted by the sun. Tanning lamps and tanning beds are also major sources of UV rays. There are three main types of UV rays, two of which can have serious health consequences for people. It’s common knowledge that excessive exposure to sunlight increases the risk of skin cancer, but it’s just as important to protect the eyes from these harmful rays. The next time you visit an optical center in Chicago for an eye exam or LASIK consultation, consider talking to your eye doctor about how you can protect your eyes from UV rays.

Identifying the Dangers of UV Rays

During UV Safety Month, take a few minutes to learn about the ways unprotected sunlight exposure can harm the eyes. UV rays can damage the eyes in several different ways. They increase the risk of cataract development, which are cloudy areas on the lenses. They can cause photokeratitis, which results in temporary vision loss. UV rays can even increase the risk of macular degeneration, pinguecula (yellow bumps on the eye), and pterygia (disfiguring bumps that cause blurry vision).

Protecting Yourself from UV Rays

It’s commonly thought that protection from UV rays isn’t as important on cloudy days or during the winter. In fact, a significant percentage of UV rays can still penetrate your eyes and skin on cloudy days. Likewise, cold temperatures do not mitigate the effects of UV rays on your eye health. For optimum eye care , your eye doctor is likely to recommend that you wear protective sunglasses every time you go outdoors. A wide-brimmed hat is also a good idea. Choose wraparound-style sunglasses that protect your eyes from all angles. Select a pair that is labeled to offer 100 percent UV protection or ask your eye doctor for recommendations.

Protecting Kids from UV Rays

Children are even more susceptible to eye damage from UV exposure compared to adults. Protect your child’s eyes by encouraging him or her to wear sunglasses that block UV rays. Let your child choose the style and color of sunglasses, provided they are labeled for 100 percent UV protection. Additionally, let your child choose a wide-brimmed hat to wear outdoors for even better protection.
