Following a neurological event such as a traumatic brain injury, cerebrovascular accident, multiple sclerosis, cerebral palsy, etc., it has been noted by clinicians that persons frequently will report visual problems such as seeing objects appearing to move that are known to be stationary; seeing words in print run together; and experiencing intermittent blurring. More interesting symptoms are sometimes reported, such as attempting to walk on a floor that appears tilted and having significant difficulties with balance and spatial orientation when in crowded moving environments.
It’s no surprise that visual-perceptual delays are common in children with Sensory Intergration dysfunction. Visual-perceptual skill refers to a person’s ability to interpret, analyze, and give meaning to what he sees. Normally more than 70 percent of classroom “underachievers” have problems processing visual information, even if they have 20/20 eyesight.
If your child shows signs of visual problems, such as difficulty reading, headaches and eyestrain, or visual inattention and distractibility, you may be referred to behavioral optometrist (also called a developmental optometrist). This is different from optician who works in an eyeglass store or an ophthalmologist who specializes in eye disease.
A headache is a symptom of an underlying condition. There are many types of headache, ranging from a sensation of mild pressure to severe migraine. Most headaches are caused by a combination of triggers including stress, poor diet, muscle tension and eyestrain.
Q: What is a headache?
A: Headaches occur when tissues or structures in and around the brain such as blood vessels, nerve fibres and sinuses are irritated, compressed or inflamed. Headache can result from referred pain from tooth, neck or eye problem.
Right now as you read these words your eyes are fixating (looking) at successive points along the screen. Visual fixation (looking) is the neuromuscular aiming of the eyes at a specific point in space. You can easily understand the need for fixation when you imagine someone involved in detailed work, like threading a needle, or sporting activities, such as throwing a baseball. According to many researchers fixation is determined by three basic factors; salience of the visual stimulus, memory or importance of the stimulus, and the nature of an activity we are engaged in.
Can a movie ticket change your life? It would seem so, at least for one movie fan.
Dr. Bruce Bridgeman and his wife walked into a movie theatre, picked up their 3D glasses and found a seat in preparation to view the 3D film Hugo. Donning the 3D glasses, Bridgeman, afflicted with the inability to process depth perception, was prepared only to eliminate the confusion of viewing a 3D film without filtration. Instead, the event left him nothing short of euphoric.
SUSAN BARRY'S NEW BOOK ON VISION
Mon, 07/20/2009 - 15:23 — billg
Neurobiologist Susan Barry finally found her 3-D vision at age 48 - with the help of vision therapy.
She's just published a new book about her journey - 3 surgeries as a child fixed her cross eye - but not her vision - experts told her "that's just the way it is" - adults can't change their vision.
Susan Barry did - with Dr. Theresa Ruggiero, a developmental optometrist located in Northampton, MA.
The visual process can be protected by simple precautions such as proper lenses, posture, lighting, ergonomics and working distance. Some pointers are provided.
Vision therapy is highly successful in remediating a lazy eye. Much akin to other physical therapies, vision therapy stimulates and guides visual development, training the brain to perform visual functions that did not develop on their own. Vision therapy is prescribed by Optometrists who specialize in children's vision and who have received board certification in this area of care.
