Overlooked Risks at School

Dangers of Blue Light Sugar Land TX Optometrist Eye Doctor Exam Fort Bend ISD Technology Center Back to School

Aside from backpacks, pencils, papers and other school supplies, have you also provided protection for your child from the long-term environmental dangers lurking in classrooms and hallways? Digital light and energy-efficient lighting in schools increase risks for macular degeneration, eyestrain, sleep disturbances and cataracts. Clinical studies, in fact, indicate that children absorb more of this harmful light. Symptoms of eyestrain include sore and irritated eyes and difficulty focusing.

Back to School, Vision and Academic Success

Back To School Vision Exam Eye Doctor Sugar Land TX Optometrist Near Me

In a clinical study involving 4th and 5th grade students who had eyesight worse than 20/25, more than 60% of those students suffered from reading difficulties.

Reading is the primary route of learning in school, and 80% of what a child learns first filters through the visual system. Screenings at nurses’ and pediatricians’ offices can miss up to 50% of the visual problems that affect reading, writing and learning.

A yearly eye exam is recommended for every child entering school. In children who are struggling with academics, a more in-depth visual skills exam is needed to investigate how the eyes, brain and entire visual system are working. These visual skills – eye coordination, focusing, fine eye movements, etc… – affect academics. Not every eye doctor – optometrist or ophthalmologist – tests and treats visual skills. With school just right around the corner, start with a yearly eye exam, and then if needed, follow-up with a thorough visual skills exam.

Watch Your Step: How Vision Leads Locomotion

Sugar Land TX Optometrist Eye Doctor Eye Exam

Using new technologies to track how vision guides foot placement, researchers at The University of Texas at Austin come one step closer in determining what is going on in the brain while we walk, paving the way for better treatment for mobility impairments — strokes, aging and Parkinson’s — and technology development — prosthetics and robots.

Walking on natural terrain takes precise coordination between vision and body movements to efficiently and stably traverse any given path. But until now, both vision and locomotion have been studied separately within controlled lab environments, limiting understanding of how various neural and biological systems work together to navigate the natural world.

“One of the beautiful things about visually guided walking is that it involves every level of our perceptuomotor hierarchy. To really understand it, you need to know how vision works, how planning works, how muscles work, how spines work, how physics work,” said Jonathan Matthis, a postdoctoral researcher in the UT Austin Center for Perceptual Systems.

Matthis’ research, published in Cell this April, combined new motion-capture and eye-tracking technologies to track distinct patterns between the two mechanisms. To do so, researchers jerry-rigged a welding mask around an eye tracker — to shade the infrared eye cameras from sunlight — and developed new methods to calibrate the eye tracker with a motion-tracking suit to record gaze and full-body kinematics as participants navigated through three types of terrain: flat, medium and rough terrain.

“Eye movements are incredibly informative as a window into the cognitive process,” Matthis said. “By tracking eyes, we get a clear picture of the kind of information the central nervous system needs to complete any given task.”

Researchers found that participants displayed distinct walking and gaze patterns in each of the terrains. Subjects walked quickly with longer strides on the flat terrain, looking down only about half of the time to briefly scan the upcoming path for obstacles.

On the medium and rough terrain, steps became shorter, slower and more variable, with participants looking at the ground more than 90 percent of the time to precisely fixate upcoming footholds. In the medium terrain, walkers focused primarily on where their foot would be in two steps. The rough terrain required walkers to split their gaze between their future foot placement in two and three steps to allow for longer-term path planning.

Despite these differences, an unexpected pattern emerged: In all three terrains, participants consistently looked 1.5 seconds ahead of their current location. This finding is similar to lookahead timing seen in research on other motor actions — stair climbing, driving and reaching — suggesting that this timing plays an important role in human movement.

“The constant lookahead time suggests that walkers are maintaining some sort of global locomotor strategy that is being tuned to each specific environment,” Matthis said. “Walkers use gaze to ensure that they always know what will be coming up 1.5 seconds down the path.

“Good action decisions require not only good sensory data, but also a consideration of the costs and benefits of the action,” Matthis said. “Taking this type of research out of the lab and into the real world allows us to observe human behavior in its natural environment. This gives us more opportunity to discover things we didn’t expect, which will help us advance our scientific knowledge to the benefit of improving clinical treatment of gait-related disorders.”

Concussion Duration and Treatment in Sugar Land, TX

Sugar Land TX Concussion Treatment Eye Doctor Exam Optometrist Headache Double Vision Light Sensitivity

The most common initial symptoms after suffering a concussion are headache, dizziness and fatigue. However, other secondary symptoms often develop afterwards that affect emotional status and cognitive ability. The time course of these symptoms can be debilitating for students. According to a study involving almost 300 students between the ages of 11 to 22 years, one week after injury:

• more than two-thirds still suffered from headache
• a majority still complained about poor concentration, dizziness, fatigue and taking longer to think
• more than 40% still struggled with forgetfulness, light sensitivity and noise sensitivity.

Various studies have shown that eye movements are intimately affected post-concussion. Research also shows that improving eye movements will help improve concussion symptoms. A study involving college athletes even showed that improving eye movements helped reduce the incidence of concussions.

Amblyopia Affects Reading

Amblyopia Doctor Sugar Land Eye Exam Optometrist Missouri City Rosenberg Richmond TX

  • Approximately 1-2 children in every classroom will suffer from amblyopia
  • Amblyopia is the most common one-eyed vision impairment in children
  • Amblyopia slows down reading speed

Reading is heavily reliant on a person’s vision. The parts of vision that are important in reading include eyesight as well as other visual skills such as eye coordination, eye focusing and fine eye movements. Clinical studies show that children with amblyopia read approximately 25% slower than their non-amblyopic counterparts. These studies involve “normally-reading” students rather than those diagnosed with a reading disability. Reading speed affects fluency, and fluency affects comprehension.

Amblyopia is the inability to see 20/20 out of each eye even with optical correction despite the absence of eye disease. Differentiating children who are actually amblyopic versus those who would be able to see 20/20 with a prescription is important. The prognosis for amblyopia is good if it is detected early enough, diagnosed properly and subsequently treated appropriately.

More Allergies!

Itchy Red Watery Eyes Sugar Land TX Eye Doctor Exam Optometrist

There are four categories of eye allergies. Treatment is dependent on proper identification. The conjunctiva, which is the white part of the eye and the underside of the eyelid, is a fantastic place to help identify allergies. Eye allergies, according to clinical studies, are under-diagnosed and can affect a person’s ability to engage in various activities including school, work and recreation. Proper and quick treatment can alleviate symptoms and improve quality of life.

Eye Allergies – Scratch, Scratch, Scratch

Eye Allergy Conjunctivitis Red Eye Itchy Eye Sugar Land Doctor Treatment What Causes Optometrist

40%-80% of allergy sufferers have symptoms involving the eye. In some instances, ocular symptoms are the only indication of allergies. However, only 10% of people who have ocular symptoms seek professional help. The majority of people either just suffer through the symptoms or try oral allergy medications. Randomized clinical trials, however, show that prescription topical medications are superior in relieving symptoms and preventing chronic inflammation due to ocular allergies. In addition, oral medications can adversely affect the eye’s surface thereby making symptoms even worse.

Amblyopia

Amblyopia Glasses Sugar Land Pediatric Eye Doctor

Amblyopia is the most common cause of childhood vision loss.  Proper diagnosis of the type of amblyopia is crucial for prognosis and treatment.  Oftentimes, the first step in treating amblyopia is glasses.  However, some children will not accept the prescription initially because of how their visual system is locked into working.  Appropriate identification and medicinal management of these children to improve their acceptance of the treatment is vital in overcoming amblyopia.
