Diabetic eye disease and eye problems are well known by most patients because their primary care physician and eye doctor tell them repeated about the need to for tight blood sugar control in order to prevent eye problems. But most patients with diabetes are unaware of some unexpected health problems that can be related to diabetes and can be easily overlooked.

Cognitive, Memory & Brain Function Decline

It is not uncommon for Type 2 Diabetics to experience diminished ability in memory recall and focus, as well as organizing, planning and completing tasks. Research shows that people with diabetes have abnormal blood flow to the brain, which affects function and activity. This explains why, with age, diabetics may experience slower mental performance. This is another reason why managing your diabetes  requires a proactive effort to carefully follow your doctor’s instructions for proper diet, exercise, medications, lifestyle and glucose levels, as well as scheduling regular follow up visits and keeping all appointments.

Hearing Loss

Did you know that diabetics are twice as likely to experience hearing loss as they age? The National Institutes of Health also reports that 30 percent of pre-diabetics, with higher-than-normal glucose levels, can experience hearing loss. The disease can affect the small blood vessels in the inner ear, causing impairment. Protect hearing by regularly monitoring blood sugar levels.

Gum & Periodontal Disease

Did you know that diabetics are more prone to developing periodontal disease, an infection of the gums that can lead to tooth loss? A study of 9,000 people at the Columbia University Mailman School of Public Health discovered that individuals with higher levels of periodontal disease were more likely to become diabetic within the next two decades, as compared to those without the disease. Periodontal disease can increase blood sugar, making it even more difficult to control diabetes. Be proactive and prevent oral health and gum problems by brushing twice daily, flossing once each day and using an antiseptic mouthwash daily.

Obstructive Sleep Apnea

About 50 percent of diabetics experience obstructive sleep apnea. People who are obese and have a collar size of more than 17 for men or 16 for women are more likely to suffer from apnea when they sleep. Researchers reporting in American Journal of Respiratory and Critical Care Medicine noted that people with severe cases of obstructive sleep apnea may have a 30 percent higher risk for developing diabetes. OSA is an increases risk factor for many eye problems including glaucoma.

While these are some unexpected diabetic health problems, the avoidance and management of diabetic retinopathy is critical. The best way to prevent vision loss from diabetic retinopathy is through early detection, diagnosis and treatment with regular eye exams.

Cataracts Driving

Blurry, cloudy vision from cataracts is a well known driving risk, especially for seniors where declining vision is often caused by cataract development. Researchers reporting in the Journal of Cataract & Refractive Surgerystudied cataracts and the outcomes of cataract surgery and how these impacted crash risk, driving self-regulation practices, and driving performance. Not surprising there was clear consistent evidence that cataract negatively affects driving and that cataract surgery is beneficial to driving outcomes. What was not clear and requires further study is how specific vision measures such as visual acuity, contrast sensitivity and glare sensitivity specifically affect crash risk and driving performance so that we can be optimally effective in prioritizing cataract patients for surgery.

Dry Eye Problems during Breast Cancer Treatment

Did you know that certain types of breast cancer treatment medications can cause dry eye symptoms? The class of medications called “aromatase inhibitors” (AIs) has been studied and found to cause dry eyes. Fortunately, we also know that this is a newly emerging, and easily treated side effect of AIs. But we need to know that you are taking one of the AIs in order to offer help for your dry eyes. Some of the medications in this class include Arimidex, Aromasin and Femara-although there are many others. Researchers used a validated questionnaire to assess the presence of Dry Eye Syndrome (DES). They found that DES is significantly more prevalent in women on AIs compared with controls. They recommend routine screening of patients on AIs with the Ocular Surface disease Index (OSDI) questionnaire with the aim of improving patient quality of life and possibly adherence.

If you or someone you know is being treated for breast cancer with aromatase inhibitors (AIs) and suffers from dry eyes, grittiness or is generally experiencing eye problems of fatigue or dryness, please call The Eye Clinic of Texas, an affiliate of Houston Eye Associates, at 800-423-3937, visit The Eye Clinic of Texas, Google+  or facebook.com/ecot.lasik.

eyeliner

Eyeliner can be applied to create a new look, or enhance natural eye appearance. But our eye doctors want to share some tips and alert eyeliner wearer to watch when and where eyeliner is applied. Three tips for safe application:

When to Apply-If you’re running late to work, school or an appointment, you may be tempted to grab your makeup and apply it in the car. But don’t use eyeliner when the car is moving, you could injure or poke your eye. A better idea is to wait until you are safely parked.

Keep It Clean-Eyeliner pencils periodically need sharpening for easy application. Use a makeup sharpener, not a kitchen or pocket knife, or a sharpener used for pencils or crayons. Prevent spreading germs to your eyes by washing your hands before using eyeliner, and don’t borrow or share eyeliner products with others. This includes liquid and cream eyeliners as well.

Watch the Location-Applying eyeliner along the inside edge of the eyelid, called the waterline, can enhance the look of your eyes. But it also may increase the risk for contamination and vision problems. Studies show that flecks from eyeliner, especially those with glitter, may drop into the eye and collect in tear film. Vision may become blurry, and eyes may become red and irritated. A bacterial infection also may develop. This is a problem, especially for those who wear contacts or have dry, sensitive eyes.

If you have cataracts or are considering cataract surgery and lens implants, if you are a good candidate, it is pretty likely that your cataract surgeon will offer you the option of a multifocal lens implant in addition to the standard monofocal lens implant. The objective of using a multifocal lens implant to correct vision after cataract surgery is to help patients become less dependent or completely independent of glasses after their cataract is removed. A multifocal lens implant allows patients to see at a range of far, arms’ length and near without glasses whereas a monofocal will require the patient to still need glasses for most arms’ length or close vision tasks. Whenever we present or recommend this option to our patients they almost always ask, “Which one is better?” or “Which one will I be most satisfied with?” A multisite clinical trial was conducted and reported on in the Journal of Refractive Surgerythat compared outcomes and patient satisfaction of monofocal vs. multifocal lens implants after cataract surgery.

Results of Cataract Surgery with Monofocal vs. Multifocal Lens Implants

The results showed both monofocal and multifocal IOLs provided good clinical outcomes. More patients receiving multifocal IOLs attained better uncorrected visual acuity at a range of distances and spectacle independence compared with patients who received monofocal IOLs. Patient satisfaction was significantly better in the multifocal group.

“I was a contact lens wearer and definitely wore them longer than I should and never cleaned them.  I came to The Eye Clinic of Texas initially because I had something in my eye that was becoming increasingly painful.  I thought it was because I had a piece of grass or dirt in my eye.  Dr. Van told me I had developed a pretty significant corneal abrasion from overuse and abuse of my contacts.  For the next week or so I had to use eye drops several times a day and could not wear my contacts which forced me to wear my 10 year old glasses which were broke and out of style.  I followed up with Dr. Van and my abrasion was healing well.  Then Dr. Van suggested I consider LASIK, especially since I abuse the wearing of my contacts.  I had never thought about LASIK until Dr. Van mentioned it. It made sense to me, no more contacts, no more corneal abrasions or contact lens expenses or glasses expenses.  The bad part was that she made me wait 2 months before having LASIK to ensure my abrasion was fully healed, during which I had to wear those ugly glasses.  Even though I had the pain of the corneal abrasion, I am glad I came to The Eye Clinic of Texas and that Dr. Van recommended LASIK for me.  I have never seen so clearly in my life! “- Robert L.

computer eye strain

Contact Lenses Increase Computer Vision Syndrome

Computer Vision Syndrome (CVS) is a condition that results from prolonged focusing of your eyes on a computer or other display device for protracted, uninterrupted periods of time. Typical symptoms of CVS include headaches, blurred vision, neck pain, eye redness, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo, dizziness and difficulty refocusing the eyes. According to the National Institute of Occupational Safety and Health, computer vision syndrome affects about 90% of the people who spend three hours or more a day at a computer. We now know that CVS is actually made worse by contact lens wear. According to a study in Ophthalmic & Physiological Optics contact lens wearers are more likely to suffer CVS than non-lens wearers, with a prevalence of 65% for contact lens wearers. In particular, people who wear contact lenses and are exposed to the computer for more than 6 hours per day are more likely to suffer CVS than non-lens wearers working at the computer for the same amount of time.

I have been a patient at The Eye Clinic of Texas League City office for almost 3 years. I have never been more pleased than I am now. Dr. Van is an excellent doctor, very skilled and knowledgeable. The staff is very pleasant and professional. They make me feel at ease when I am there. I had very poor vision but not anymore. I first scheduled an eye exam because my vision was deteriorating.  I was told I needed cataract surgery and chose the ReSTOR lens which would correct my near, distance and intermediate vision. After I healed from cataract surgery, I had Lasik to correct my astigmatism. I was told prior to surgery that because of a condition with my retinas that my vision might not improve completely. Much to my amazement with Dr. Van’s knowledge and skill my vision has come from -15 or higher with astigmatism to 20/25. The day after the Lasik I could read and work without my glasses. This to me is close to a miracle because I have had very poor vision for 50+ years. Dr. Van’s skills did this for me.

Teri M told us about her cataract surgery experience…

“I initially came to ECOT for a routine eye exam to update my glasses.  I had a few complaints like glare and halo when I drove at night and I also felt like I saw a fog in my vision.  I thought my glasses were just old since I hadn’t had an eye exam in many years.  Upon my exam, it was determined that I had cataracts and needed surgery.  It wasn’t something I was prepared to hear that day, especially since I thought I was having just a regular exam.  After speaking with the surgery counselor and again with Dr. Van, I felt confident in ECOT care and had my first cataract surgery last June.  WOW is all I could say.  I was seeing things that I hadn’t seen so bold and vibrant since I was a kid.  I absolutely could not wait for the second surgery which was 2 weeks later.  Once both eyes had been operated on, I now only need glasses to read.  I started driving at night again.  I am so happy now that I was diagnosed with cataracts on that visit because you don’t realize how bad your vision is or was until after surgery and my vision is excellent!

african eye

Glaucoma is an eye disease that if untreated can damage the optic nerve, impair vision and cause blindness. It is particularly sight threatening in that in its most common form it doesn’t strike the patient with any warnings or symptoms. Thus, becoming familiar with glaucoma risk factors is worthwhile for all patients.  While we have known for quite some time about the increased risk among family members and certain ethnic and racial backgrounds, those patients of Latino or African, ancestry are clearly at greater risk for high pressure within the eye and thus should be aware of the need for routine eye exams and glaucoma testing at the direction of their eye doctor. Researchers from the UIC College of Medicine analyzed data from 3,541 participants 40 and older from the Mexican American Glaucoma Genetic Study, part of the Los Angeles Latino Eye Study and found that as the percent of African ancestry went up, intraocular pressure rose.

According to a report in the journal Ophthalmology, African ancestry carried more risk for high intraocular pressure than high body mass index, older age and high blood pressure-factors known to contribute to increased pressure inside the eye. The key to preventing vision loss from glaucoma is early detection, diagnosis and treatment.

If you or some you know has known glaucoma risk factors including diabetes, high blood pressure, is a smoker, has a family history of glaucoma, obesity or suffers from sleep apnea and you are of Latino or African ancestry, it is quite important that you have regular eye exams and glaucoma testing.
