Eye Problems from ADHD Medication

If you, your child or someone you know takes ADHD medication it is important to understand the possible side effects that might impact eyes, cause eye problems and alter vision. The most common prescription medication we see children and even adults taking for treatment of attention deficit hyperactivity disorder (ADHD) is methylphenidate which has a number of trade names such as Ritalin, Concerta, Adderall, Methylin and Daytrana. While the common side effects of loss of appetite, nervousness and difficulty sleeping are easily recognized, researchers reporting in the Journal of the American Association for Pediatric Ophthalmology and Strabismus raised some concern that this treatment may be associated with increased risk of angle closure glaucoma and a disturbance of eye refraction and optical prescriptions. They initiated a study to investigate the effects of methylphenidate treatment on refraction, intraocular pressure (IOP), and the anterior chamber in children with ADHD. This was a pilot study where children diagnosed with ADHD were examined before the start of methylphenidate treatment and again 3 and 9 months after the start of treatment. Their examinations included an eye exam with ordinary as well as cycloplegic refraction-one performed with eye drops and high resolution imaging study of the anterior chamber of the eye where the delicate structures related to glaucoma could be viewed and measured.

ADHD Medication Eye Study Conclusions

The researchers found that methylphenidate does not seem to affect refraction, or optical prescription in most children with ADHD. But, after 9 months of treatment there was a reduction in the eye anterior chamber depth, which has been described as a powerful predictor of angle closure glaucoma. As this was a pilot study more work is needed to really understand any increased risk.

What You Need to Know and Do

If you, your child or someone you know is taking methylphenidate of any type for ADHD, it would be worthwhile scheduling a routine eye examination so that we can measure the refraction, the intraocular pressure (IOP) and anterior chamber angle and depth. We do this regularly during your eye exam. BE SURE TO TELL US YOU ARE TAKING METHYLPHENIDATE. If your eye exam is normal we will most likely ask you to have a repeat exam in a year. BUT, if at any time there s a change in your vision, pain, redness, glare or light sensitivity we want you to call right away and schedule an immediate appointment for that day.

If you or someone you know is being treated for ADHD with methylphenidate medications such as Ritalin, Concerta, Adderall, Methylin and Daytrana, it is important to have a routine eye exam to avoid any risk of eye problems 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.

About Multiple Sclerosis

Multiple sclerosis (MS) is a debilitating neurological disease that can cause patients to experience decreased vision due to optic neuritis, an inflammation of the optic nerve, as well as diplopia or double vision. We believe that MS occurs because there is an abnormal response of the body’s immune system whereby it is directed against the central nervous system (CNS), which is made up of the brain, spinal cord and optic nerves. Within the CNS, the immune system attacks myelin-the fatty substance that surrounds and insulates the nerve fibers as well as the nerve fibers themselves. When any part of the myelin sheath or nerve fiber is damaged or destroyed, nerve impulses traveling to and from the brain and spinal cord are distorted or interrupted, producing a wide variety of symptoms. 

About Optical Coherence (OCT) Eye Testing for MS

In our office, we routinely use very precise imaging technology called Optical Coherence Tomography (OCT) as part of evaluation, diagnosis and monitoring glaucoma and retina diseases because it allows us to examine the actual nerve fibers of the retina and the optic nerve.

Recent research has taught us that OCT can be used to monitor the degree of atrophy of specific retinal layers-called the “inner plexiform layer” and “ganglion cell layer”-and used as an as an indicator of neuronal tissue damage in patients with multiple sclerosis (MS). For patients with Multiple Sclerosis this is quite valuable as it gives us a non invasive in office test, that in concert with their neurologists, helps us help patients asses the stability of their disease as well as their response to new medications or treatments.

Lazy Eye Amblyopia: What is it?

Amblyopia or “lazy eye” is a very common vision problem that we see in children. In fact it is responsible for more vision loss in kids than all other reasons combined. Amblyopia is a decrease in the child’s vision that occurs even without any structural problem being present. The decrease in vision results when one or both eyes send a blurry image to the brain. The brain then “learns” to only see blurry with that eye, even when glasses are used. Only children can get amblyopia. If it is not treated, it can cause permanent loss of vision. There are a number of types of amblyopia including strabismic amblyopia which is caused by an eye alignment or eye turning problem, deprivation amblyopia which is caused by cataracts or other condition that “deprives” the eye of a visual image and refractive amblyopia which is due to an uncorrected refractive error such as farsightedness or astigmatism.

Depending on the cause of the amblyopia and whether there is an underlying uncorrected refractive error sometime glasses can help but will not correct the vision to 20/20.  With amblyopia, the brain is “used to” seeing a blurry image and it cannot interpret the clear image that the glasses produce. With time, however, the brain may “re-learn” how to see and the vision may increase. Remember, glasses alone do not increase the vision all the way to 20/20, as the brain is used to seeing blurry with that eye.  Because of this most of the time the normal eye is treated with patching or eye drops to force the amblyopic eye to be used and make it “stronger.” to make the amblyopic (weak) eye stronger.

“My wife told me for years to go have the procedure but I never did. I always made excuses and let time get in the way. Finally, I had LASIK last year and it is the best money I have ever spent on myself. I can see so clear when I ride my bike and go deer hunting. My vision is better than what it was when I wore my contacts, something I couldn’t fathom! It is such a refreshing feeling to get up in the morning and not have to put contacts in or grab my glasses.”

Eye health and vision problems from contacts lenses can be prevented by avoiding known risky behaviors. According to the Centers for Disease Control and Prevention almost all of the 41 million estimated contact lens wearers in the United States may be engaging in at least one behavior known to increase their risk of eye infections. Nearly one-third of contact lens wearers who participated in a national survey reported going to the eye doctor for red or painful eyes related to wearing contact lenses. More than 99 percent of survey respondents reported at least one risky behavior. The majority of wearers reported:

• Keeping their contact lens cases for longer than recommended (82.3 %)
• “Topping off” solution in the case by adding new solution to the existing solution instead of emptying the case out fully before adding new solution (55.1%)
• Wearing their lenses while sleeping (50.2 %)

Each of these behaviors has been reported in previous studies to raise the risk of eye infections by five times or more!
An online survey was administered to a sample of contact lens wearers to determine how often contact lens wearers engaged in behaviors that could put them at risk for an eye infection. CDC collaborated with the Contact Lens Assessment in Youth (CLAY) group, a multi-university group of researchers, to conduct the survey. A separate survey was used to estimate the number of contact lens wearers – about 41 million adults. Taken together, the survey results indicate that millions of Americans could be at risk for serious eye infections because of poor contact lens hygiene behaviors.

We know that contact lenses can be worn safely if wearers are mindful of using good hygiene. To prevent eye infections, contact lens wearers should:
• Wash hands with soap and water and dry them well before touching contact lenses
• Take contacts out before sleeping, showering or swimming
• Rub and rinse contacts in disinfecting solution each time they remove them
• Rub and rinse the case with contact lens solution, dry with a clean tissue and store it upside down with the caps off after each use
• Replace contact lens cases at least once every three months
• Avoid “topping off” solution in lens case (adding fresh solution to old solution)
• Carry a backup pair of glasses in case contact lenses have to be taken out

Dry Eye Slows Reading Speed

Anyone who experiences the symptoms of dry eye is familiar with dryness, discomfort, burning, light sensitivity and even watering that can mark the presence of dry eye disease. But, did you know that dry eye problems and disease can impact visual function? Researchers reporting in Cornea compared visual function using reading tests including the Radner Reading Test, the International Reading Speed Texts [IReST], and the Wilkins Reading Test and studied cognitive function, fatigue, dry eye symptoms, reading acuity, reading rate and blink rate. The results showed significantly lower reading rates in all reading tests in patients with dry eye and a significantly increased fatigue level when reading in dry eye patients.

If you suffer from symptoms of dry eye such as dryness, burning, light sensitivity or watering and have noticed an uncomfortable slowing of your reading ability and even greater eye fatigue or tired eyes when reading, 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.

About Angle Closure Glaucoma

Angle Closure Glaucoma is a type of glaucoma caused by a blockage or complete closure of the drainage structure of the eye called the trabecular meshwork. The trabecular meshwork is actually a fine filter, and if it is blocked or obstructed by any alteration in the size or shape of the surrounding structures, or by change in the size or shape of the tissue itself, it will cause the intraocular pressure (IOP) to elevate. In instances where the meshwork becomes blocked abruptly, it will cause a sudden rise in the intraocular pressure (IOP), resulting in Acute Angle Closure Glaucoma. Acute Angle Closure Glaucoma is characterized by this sudden rise in pressure which will cause pain, redness, light sensitivity, colored haloes around lights, nausea or vomiting, and blurred vision, and if left untreated permanent loss of vision.

Medications Can Cause Angle Closure Glaucoma

In patients who may already be at risk for Angle Closure Glaucoma because they have certain tissue and anatomical features inside their eyes, certain medications can significantly increase their risk. Two medications that are worth mentioning are the antidepressants Wellbutrin (Buproprion) and Topamax® (Topiramate). While both of these are often used to treat mild to moderate depression, they are also used to help patients stop smoking! Researchers reporting a study in Archives of Ophthalmology found that the risk of angle-closure glaucoma in patients younger than 50 years was twice as high in patients taking Wellbutrin and more than 5 times higher in patients taking Topamax®.

If you or someone you know is being treated for depression or has been prescribed Wellbutrin or Topamax® to help stop smoking, please make sure you tell your eye doctor and ask about your risk of Angle Closure Glaucoma, as well as become familiar with the symptoms above. If you have not had an eye exam with glaucoma testing and are taking these medications, 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.

Cataracts are a rather frequent cause of night driving problems. In fact, patients may not be aware that the degree of night vision problems can be particularly disturbing even with a pretty mild cataract. Night driving tends to be difficult enough because the overall low light levels can cause you to misjudge distances and boundaries like the edge of the road or distance to a street or exit. Further, even mild cataracts can cause night glare off car headlights and tail lights and be quite annoying. So, what we need patients to be aware of is that if they have been told that they have even the beginning of cataracts and are becoming fearful of night driving they need to bring this to our attention so that together we can discuss and consider whether it might be time to consider whether cataract surgery might be a good option to help you regain your night driving comfort level.

Jean S. told us about her daughter Abby’s experience at the Optical Shop…..

“I was completely impressed with The Eye clinic of Texas Optical Shop and Opticians.  They had a very extensive selection of childrens glasses and were reasonably priced.  The optician, Amanda knew so much about the type of lenses that my daughter needed in her glasses.  She recommended a high index lens because my daughter’s prescription is so large and it would help her see more clearly. “

LASIK Surgeons Know About Safety

This past October 21, 2015 marked the 20 year anniversary of FDA approval of the use of the excimer laser for Laser Vision Correction of common eye problems such as nearsightedness or myopia. 20 years is a long time and we have now arrived with technology, techniques, skills and experience to be able to provide patients wanting to eliminate their dependence on glasses and contacts, with a safe, effective and reproducible laser eye surgery treatment-whether LASIK, PRK or other method of correction.

Patient Barriers to LASIK

Still, one of the main barriers to patients who want to have LASIK is there concern about safety. A recent study was conducted to determine what percent of LASIK & Refractive Surgeons WHO ACTUALLY PERFORMED THE PROCEDURE, have had Laser Vision Correction. Certainly, eye surgeons who perform refractive surgery MUST know the dark dirty secrets of safety issues and would avoid putting themselves at undue risk. After all…EYE SURGEONS NEED EXCELLENT VISION!

 Results of the Laser Vision Correction Safety Study

The study, called Prevalence of Laser Vision Correction in Ophthalmologists Who Perform Refractive Surgery was published in the September Journal of Cataract & Refractive Surgery and had some interesting results. Responses were received from 248 (99.2%) of 250 ophthalmologists who were queried, of which 232 (92.8%) met the criteria of currently working as refractive surgeons. Of the 232 subjects, 161 (69.4%) reported that they had refractive errors potentially amenable to treatment with laser vision correction, not including presbyopia. Of the 161 ophthalmologists with treatable refractive errors, 54 (33.5%) reported they were not candidates for laser vision correction for a variety of reasons and 107 (66.5%) reported they were candidates for LVC. Of the laser vision correction candidates, 62.6% reported that they had an LVC procedure in their own eyes! Of the overall 232 subjects, more than 90% recommend LVC for adult members of their immediate family!

The message is clear. The data speaks for itself. Two thirds of the eye surgeons who perform LASIK, and are good candidates for LASIK-HAVE LASIK! They are confident of the safety, efficacy and predictability-THAT THEY HAVE IT THEMSELVES!!!! And they recommend it to their family members. The key here to having a great result is finding out if you are a good LASIK candidate. We can help!
