King-Devick Test

Eye Test for Concussion in Student Athletes
An eye test for concussions might be helpful for student athletes playing contact sports who are known to be at risk for head trauma. Up to 3.9 million sports related mild traumatic brain injuries, or concussions, occur annually in the United States, according to the Centers for Disease Control and Prevention, but researchers say that number is likely higher since the CDC only tracks emergency room visits. Experiencing a concussion in a game increases an athlete’s risk for sustaining a second condition in the same season by three times. Other complications include the dangerous second impact syndrome, or other short and long term side effects.

Research on Concussion and Eye Tests
Research from the NYU Langone Concussion Center shows that a simple eye test, which can be administered in less than two minutes, can effectively diagnose a concussion and help determine whether a student athlete as young as 5 years old should return to a game. A study published in the Journal of Neuro-Ophthalmology, was conducted on 89 NCAA athletes and a younger group of 243 youth athletes under age 17, and shows how the eye test, known as the King-Devick test, could help minimize the problems that make the diagnosis of concussion difficult in student athletes involved in youth sports. The researchers report that the test can easily be administered on the sidelines by parents and non-health care professionals when athletic trainers and doctors are not available to monitor sidelines at youth sports games.

About the King-Devick Test
As part of the King-Devick test, athletes read numbers off of three pieces of paper while being timed with a stopwatch. A worsened performance from a baseline reading suggests a concussion has occurred. Since concussions may cause devastating short and long term cognitive effects, tools like vision testing that can objectively diagnose a concussion are critical. Some sideline tests only measure cognition and balance, but visual testing is rarely performed, despite longstanding evidence that vision is commonly affected by concussion, according to a review article published in the Journal of Neuro-Ophthalmology. Previous research suggests about 50 percent of the brain’s pathways are tied to vision.

Avoid Sports Eye Injury with Protective Eyewear

According to research on data from the High School Reporting Information Online database and from a Virginia school district that includes 25 high schools, recorded between 2009 and 2013, analyzed and  published in the journal Pediatrics, the use of mandatory protective eyewear by female field hockey players has reduced incidences of eye and orbital injuries, as well as severe face and head injuries. Among female U.S. high school field hockey players, a national mandate for protective eyewear has been associated with a greater than threefold reduced risk of eye and orbital injuries and a decreased incidence of severe eye and orbital as well as head and face injuries. This information supports a policy change and implementation of the mandatory use of protective equipment in field hockey at all amateur levels.

About Solar Retinopathy

Solar retinopathy is a condition where the retina becomes damaged as a result of bright light from the sun. The retina is made up of layers of light sensing cells that make vision possible. When they’re over stimulated by sunlight, they release a flood of communication chemicals that can damage the retina. This damage is often painless, so people don’t realize what they’re doing to their vision. Solar retinopathy has been reported to occur from staring at the sun, regardless of its phase. Sometimes people high on drugs have stared at the sun for long periods of time causing serious damage as well adherents of sun worshipping religious sects are also victims. BUT, children too can stare at the sun and painlessly lose their vision from solar retinopathy!

Sunglasses for Children Not Simply About Fashion

Making sure children wear UV protective sunglasses is important to help kid’s protect their eye health and vision as sun damage to the retina, called “solar retinopathy” does affect BOTH children and adults according to researchers reporting in the Journal of the American Association for Pediatric Ophthalmology and Strabismus.

When to Have Kids’ Eye Exams

At The Eye Clinic of Texas we are often asked about the best time to have kids’ eyes screened, examined and evaluated for eye health and vision problems. The American Academy of Pediatrics and the American Academy of Ophthalmology recommend that your child’s eyes be screened for problems at birth, by 6 months of age, at 3 to 4 years of age, at 5 years of age, and every following year. Getting your kids eyes checked and screened regularly is critical for finding any issues that should be caught treated early. In most instances it may not actually be necessary for your child to have an exam with an eye doctor as your pediatrician can do the initial screenings at the routine well child visits. However, for preemies or if there is any family history of childhood eye problems it’s probably a good idea to bring them in to see us and we might recommend more frequent or more detailed exams.

About Headaches and Childrens’ Eye Problems

It is pretty common for parents to bring their children in for an eye exam because they are complaining of headaches. Headaches are a frequent complaint of kids but fortunately they are usually not serious. Some of the more common causes of headaches in kids include migraine, the stress and tension of school, certain foods with nitrate or MSG preservatives, physical trauma, sinus infections and of course eye problems. Parents can be concerned with the serious but truly rare occurrence of brain tumors causing headaches but this is usually accompanied by other complaints of dizziness, weakness of arms and legs and a loss of coordination.

Evaluating Kids with Headaches

As part of evaluating any child with headaches I always want to be sure that there has been a complete and thorough examination by their pediatrician who may need to order additional tests or even a referral to a neurologist. Then I will need to perform a complete eye exam including evaluation of the pupils, a refraction to determine any refractive error or  need for glasses, eye alignment and binocularity testing and sometimes possible a visual field examination. Generally I will put drops in the child’s eyes to dilate the pupils, so that the optic nerves can be properly examined and the refractive error can be most accurately measured.

Eye Problems That Can Cause Headaches

If your child has uncorrected hyperopia or farsightedness, it requires extra effort to focus clearly while reading.  This can sometimes lead to fatigue and headache.  Glasses can reduce the effort required to see clearly at near and improve the headache, if significant hyperopia exists.  Mild hyperopia is normal in children, however, and generally does not cause headaches or other symptoms.

When we read or perform other near activities, our eyes pull in toward each other, this is called convergence. The decreased ability to pull the eyes toward each other when viewing near objects (convergence), particularly while reading, may cause headaches.  This is called convergence insufficiency, and symptoms include the doubling of images or words, blurred vision, fatigue, and headaches which worsen with prolonged reading.  At home eye exercises, sometimes with the help of computer software, can help treat convergence insufficiency. Glasses are sometimes prescribed, but costly in-office eye exercises are rarely necessary.

Acute infections, allergic and inflammatory diseases of the eyes can also cause headaches.  These problems are often accompanied by redness of the eye and/ or the eyelid as well as light sensitivity or photophobia. Acute glaucoma can cause headaches, but rarely affects children.  Pseudo tumor Cerebri is a condition caused by increased intracranial pressure or too much fluid around the brain, and this causes headache and swelling of the optic nerves, but does not typically cause redness of the eyes. During the complete eye exam we perform we will be able to rule out these problems as a cause of headaches in your child. If we do not find any ocular causes of your child’s headache we may refer them back to his/her pediatrician and/or to a neurologist to look for other possible causes of the headaches.

About Nearsighted Progression

Anyone who has a child or teenager who is becoming more and more nearsighted each year wants to know if there are ways we can prevent the progression of myopia. Over the years there has been discussion of trying to under correct the nearsightedness, rather than prescribing the full correction, in order to slow down nearsighted prescription changes. Researchers reporting in Grafe’s Archives for Clinical and Experimental Ophthalmologystudied the effects of undercorrection of myopia on myopia progression and eye length elongation in a population of 12-year-olds. They followed more than 2,000 children for 1 year and used careful analysis to consider the effects of how much near work, how much outdoor activity and the amount of time glasses were actually used as well as the degree of nearsightedness. They tested them by measuring their cycloplegic auto refraction, axial length of the eye, visual acuity and near vision focusing lag. The results demonstrated that over a period of 1 year, prescribing an undercorrection or full correction of myopia by wearing spectacles did not show any differences in myopia progression. Whether this would be the same result for younger children, or if the correction was prescribed in contact lenses or over a longer period of time is not certain but initially suggests that it is not helpful to under correct nearsighted children with glasses to slow myopic progression.

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.

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.

Regular eye exams are the best way to help prevent vision loss from diabetic retinopathy. The eye examinations for diabetic retinopathy need to be thorough and when necessary include advanced testing such as retinal photography, fluorescein angiography and ocular coherence tomography (OCT) in order to really document how the retina and it’s blood vessels are functioning. Depending on the severity and the risk of progression of each patient’s diabetic retinopathy we will advise them of the frequency and intervals for their exams. But, patients with diabetes need to know that it is terribly important to keep their appointments.

Vision loss from diabetes and especially catastrophic vision loss from diabetic retinopathy can be prevented with early detection, diagnosis and treatment. If you or someone you know has diabetes or even elevated blood sugar levels they should work to prevent diabetic eye disease and problems with regular eye exams by calling The Eye Clinic of Texas, an affiliate of Houston Eye Associates, at 800-423-3937, visiting The Eye Clinic of TexasGoogle+ or facebook.com/ecot.lasik.
