AMD Distortion Help with Optical Physics

Dr. Stephen Buck commented on how the application of optical physics might be helpful to patients with visual distortion caused by age related macular degeneration (AMD). “Even with the very successful treatment of macular degeneration with Lucentis® injections, we still encounter patients who experience a disturbing distortion and twisting of their vision resulting from macular degeneration,” explained Dr. Buck.

Nobel Laureate Walter Kohn described a potential application of what is a dynamic “translator” for the particular distortion a patient experiences either in handheld computers or an optical corrective lens. “We routinely use the Amsler Grid, a graph-paper-like pattern to diagnose AMD-Dr. Kohn suggested that the Amsler grid could also be used to develop an optical correction,” said Dr. Buck.

When people with healthy eyes look at the Amsler Grid, they see its straight horizontal and vertical lines, with a dot at center. Patients with AMD, however, often perceive a distortion about two or three centimeters in diameter in the center.

Dr. Kohn has initiated the development of software that lets an AMD patient, using a mouse, pull the virtual lines until he or she perceives the grid as “perfect,” yielding reversal of the specific distortion a person experiences. Dr. Kohn then uses these results to create a correction for that patient. In one experimental device, a handheld computer scans the printed page, using software to perform dynamic compensation, distorting the text to make it readable for patients. In addition, Dr. Kohn uses of a slab of optical material to fabricate the visual correction so that AMD patients could hold the optical slab of refractive material over text, pictures or reading material, just like the magnifying glass people use for seeing small type—only the surface of Kohn’s slab resembles ocean currents or waves that reverse the distortion.

LASIK for Glaucoma Patients

LASIK for patients with glaucoma is possible but must be evaluated for each person on an individualized basis. “We would consider performing LASIK for certain patients with glaucoma-but it really depends a great deal on the stability of the glaucoma and whether and how much damage to the optic nerve the disease has caused,” remarked Indiana LASIK Surgeon Scott Buck, M.D. of Northwest Indiana Eye & Laser Center in Valparaiso, IN.

Generally, unless the glaucoma is severe it is possible that LASIK could be an option for most patients. Other types of laser eye surgery for vision correction such as PRK might be preferred. In some cases it might actually be beneficial to have lens replacement surgery using advanced technology lens implants for vision correction.

If you or someone you know has glaucoma or is a glaucoma suspect and is considering LASIK, we would be happy to provide a free consultation to help determine if they are a LASIK candidate or perhaps a better candidate for another type of refractive surgery. Please feel free to schedule an appointment with Scott Buck, M.D at Northwest Indiana Eye & Laser Center at 219-464-8223, or visit Northwest Indiana Eye & Laser Center or facebook.com/nwindianaeyeandlaser. Let us tell you if you are even a good candidate for Laser Eye Surgery for Laser Vision Correction.

Eye Exams Test for Stroke Risk

Regular eye exams and a new eye test may prove helpful for identify patients who are at high risk for stroke “Researchers from the University of Zurich shared information about a test called Ocular Pulse Amplitude (OPA) in Ophthalmology, the journal of the American Academy of Ophthalmology. “Their study showed that the Ocular Pulse Amplitude (OPA) test can reliably detect carotid artery stenosis (CAS) or carotid artery narrowing, a condition that clogs or blocks the arteries that feed the front part of the brain which is a known risk factor for stroke. I am hopeful that we will soon be able to perform this test as part of a routine eye exam,” commented Ophthalmologist Scott Buck, M.D. of Northwest Indiana Eye & Laser Center in Valparaiso, IN.

Each year, approximately 795,000 Americans suffer a new or recurrent stroke, and more than 137,000 of these people die as a result. People with severe CAS are much more likely to suffer stroke.”We would like to catch and treat CAS before that can happen, but because CAS has no symptoms and an efficient test is not currently available the disease often goes undetected,” explained Dr. Buck.

Do Women Need Bifocals Sooner than Men?

Indiana Optometrist Dr. Stephen Buck shared research on why women need bifocals for correcting near vision focusing problems and presbyopia sooner than men. “Research in the journal Investigative Ophthalmology and Visual Science (IOVS) was quite consistent with what have observed clinically for many years,” said Dr. Buck. “The study found that women tend to need bifocals sooner to correct their near vision and the onset of presbyopia-the age related near vision focusing problem. While men and women both will need bifocals as they age, the need is more common and somewhat earlier among women than men.”

It is believed that while men and women appeared to actually have the same focusing ability when looking at nearby objects, because women are generally shorter than the men, with proportionally shorter arm lengths, they needed to hold objects closer to their faces when reading and thus required the near vision presbyopia correction of bifocals, reading glasses or even bifocal contact lenses sooner.

If you or someone you know would like to learn more about near vision focusing problems, presbyopia or bifocals please schedule and eye exam at Northwest Indiana Eye & Laser Center by calling 219-464-8223, or visiting Northwest Indiana Eye & Laser Center or facebook.com/nwindianaeyeandlaser.

IN Doctor on Eye Exams & Colon Cancer Risk

Northwest Indiana Eye & Laser Center eye doctor Scott Buck, M.D., commented that patients may wonder what eye exams could possibly have to do with your risk of colon cancer. As it turns out-plenty! The retinal pigmented epithelium (RPE) is a layer of the retina which can sometimes be thicker than normal at birth-or “hypertrophic”. Congenital Retinal Pigment Epithelial Hypertrophy (CHRPE) is usually found before patients reach 30 years of age and although they may enlarge with time they usually do not lead to malignancies like colon cancer.  “During regular eye exams when we find these areas of retinal pigmented epithelial hypertrophy typically they do not cause any vision problems or symptoms and are pretty unremarkable,” commented Dr. Buck.

However, there is an association between people with Gardner's Syndrome-Familial Colonic Polyposes-or polyps of the colon, and CHRPE. “If your eye doctor has told you that you have Congenital Retinal Pigment Epithelial Hypertrophy-perhaps called “Bear Tracks” or “Pigment Spots” or “Retina Freckles”, it is important to carefully explore and review your family history reasonable with a Gastroenterologist who will likely schedule you for a colonoscopy,” said Dr. Buck. It may be that the freckles are caused by the same genetic mutation that produces the polyps. A study published in 2010 in the American Journal of Gastroenterology concluded that patients with such freckles should be referred for colonoscopies.

Thus-when we are over 50 years of age, the reasons to have yearly eye exams includes not only detecting cataracts, glaucoma, age related macular degeneration (AMD) and other eye diseases, but regular eye examinations may very well be a reminder to be screened via colonoscopy to help detect early risks and potential indicators of colon cancer.

Eye Health and Being 40

“Taking a little extra care to protect our eye health and vision as we enter or 40’s is worth making a priority,” said Indiana Ophthalmologist Scott Buck, M.D of Northwest Indiana Eye & Laser Center in Valparaiso, IN. “It’s pretty important for adults-even without symptoms or known risk factors for eye disease to get a baseline eye examination at 40 for early detection, diagnosis and treatment of eye problems, conditions & diseases. Starting early will help to preserve eye health and vision.” Some things to consider as we enter our 40’s:

Your Eyes & Exercise
Our eyes need good blood circulation and oxygen intake, and both are stimulated by regular exercise. Regular exercise also helps keep our weight in the normal range, which reduces the risk of diabetes and diabetic retinopathy. Remember to use sun safety and protective eyewear when enjoying sports and recreation.

Your Eyes & Smoking 
Avoiding smoking, or quitting, is one of the best investments you can make in your long-term overall and eye health. Even though as you enter your 40’s old age seems a long way off, smoking can increase your risks for cataracts and macular degeneration (AMD) as well as for cardiovascular diseases that indirectly influence our eyes’ health. Smoking increases the risk of severe vision loss for people with other eye diseases, such as glaucoma, as well.

Your Eyes & Sleep
As we sleep, our eyes enjoy continuous lubrication. Also during sleep the eyes clear out irritants such as dust, allergens, or smoke that may have accumulated during the day. Some research suggests that light-sensitive cells in the eye are important to our ability to regulate our wake-sleep cycles. This becomes more crucial as we age, when more people have problems with insomnia. While it's important that we protect our eyes from over-exposure to UV light, our eyes also need exposure to some natural light every day to help maintain normal sleep-wake cycles.

Your Eyes & Systemic Health Problems
Systemic health problems like high blood pressure and diabetes that may be diagnosed or become more problematic in midlife can also affect eye health. One warning sign of both high blood pressure and diabetes is when the ability to see clearly changes frequently. Be sure to keep your eye doctor informed about your health conditions and use of medications and nutritional supplements, as well as your exercise, eating, sleeping and other lifestyle choices.

Dry Eye
This uncomfortable condition becomes more common as people age. Women are more susceptible after menopause due to hormonal changes, but incidence also increases for men as they grow older. It is usually treated with over-the-counter or prescription eye lubricants. If dry eye is severe, surgery to reduce tear drainage may be needed. If you have contact lenses, follow the use guidelines and avoid wearing lenses longer than recommended. If dry eye persists, talk to your eye doctor about possible treatments. Definitely discuss dry eye treatment with your eye doctor if you are thinking about or planning to have LASIK or other refractive surgery. Some medications increase dry eye. If you are taking pain relievers, antidepressants, antihistamines, or have questions about your medications, please bring this to our attention during your eye exam. You may wish to consider following a diet rich in omega-3 fatty acids (DHA and EPA) as it may reduce or help prevent dry eye.

If you or someone you know is entering their 40’s, it is time to schedule regular eye exams to preserve eye health and vision. Please feel free to call Northwest Indiana Eye & Laser Center at 219-464-8223, or visit Northwest Indiana Eye & Laser Center or facebook.com/nwindianaeyeandlaser.

Indiana LASIK Surgeon on Getting the Best Results

Northwest Indiana Eye & Laser Center LASIK Surgeon Scott Buck, M.D. shared advice to help you get the best LASIK results. 

Make Sure That You Are a Good Candidate 

There is simply no way to find out if you are a good LASIK candidate-or a good candidate for any type of laser eye surgery-without having a thorough eye exam and consultation that includes very specific measurements of the shape and thickness of your cornea as well a critical evaluation of the health and quantity of your tears. You cannot tell if you are a good candidate from a phone call or knowing your eyeglass or contact lens prescription. We always ask that patients come in for a consultation-which allows them to personally meet with us in order to feel comfortable and have all of their questions answered. 

Choose the Right LASIK Surgeon

There are many qualified LASIK surgeons. But if you take the time to investigate and ask around, you will find those that take the time to meet with every patient before, during and after their LASIK procedure as well having more than ten years of years of performing LASIK for patients from throughout our community. This long term experience with selecting the right patients, choosing the right types of treatments, answering preoperative questions, managing intraoperative challenges and of course working the patient through the post operative course is what drives patient success and satisfaction. 

Set Realistic Expectations

Patients should expect to see quite well in terms of vision correction. But to really be happy with the results of their LASIK, we want to walk patients through an in depth discussion of how they expect LASIK to help them. Specifically we want to know about their personal goals in terms of occupation or in the workplace, for recreational activities and sports or perhaps simply to make their day more convenient-but we want to know what they expect. This gives us something to set as a goal beyond simply their visual acuity. Setting mutually agreed upon goals and expectations is really the ultimate way to get the best results for patients and drive overall patient satisfaction. 

At the end of the day getting the best results from LASIK means you need to be a good candidate, choose the right LASIK surgeon and have realistic expectations. In our current economic climate, the challenge we have is doing this for patients each and every day with an eye on value-doing it all at affordable fees that can give them the opportunity to have LASIK within their budget. We believe we can do this for all but a very few who seek our counsel.
