These problems can be classified according to the visual skill affected: spatial skills, memory, analysis and visual auditory integration ( Table 1). Visual processing problems come into play more in that earlier phase-when a child is learning how to read. These include poor comprehension, letter and word or number reversals, difficulty remembering what was read, struggling to recognize words and problems sounding out words. In contrast, visual processing problems manifest as more cognitive/academic type symptoms. These symptoms are more common for patients in that “reading to learn” phase, when reading becomes more demanding. These can indicate a problem with refractive error, binocularity, accommodation or oculomotor skills. Visual efficiency problems manifest as signs of discomfort when reading, such as double vision, headaches, words moving on the page, words blurring and loss of place when reading. Each of these groups experiences different symptoms. Reading problems can be broken into two main classifications: visual efficiency problems and visual processing or perceptual problems. By asking more specific questions, you can better streamline your exam and testing. The phrase “reading problems” itself can mean different things to different people. Treating a patient with these reading problems starts with a detailed history. Reading assignments take longer to complete and are more demanding on the visual system. As classes become more advanced, books feature fewer images, the font size gets smaller and words get longer. This process begins in fourth grade and continues through adulthood. Once the child has mastered how to read, they begin to read to learn. Reading in school-aged children between kindergarten and third grade usually involves learning how to read learning the names and sounds of the letters and then putting them together to make simple words and sentences. Here, a young patient is seen patched and performing monocular oculomotor activity using the Home Therapy System (Vision Therapy System). ![]() They’re likely to tell you, “By the end of the day, I can’t read, I have a splitting headache and I’m seeing double.”Īll of these patients can be evaluated and managed in your optometric practice, and as optometrists we have the unique ability to change patient’s lives by treating these visual conditions. They said she has a lazy eye.” They may also present as adults who complain that a new job sits them in front of their computers all day. They’ll explain that “His teacher thinks he needs an eye exam because he has problems reading,” or, “She failed a screening. These patients are likely to present to your office as children whose parents bring them to an eye exam. In particular, the Pediatric Eye Disease Investigator Group’s (PEDIG) Amblyopia Treatment Study (ATS) and Convergence Insufficiency Treatment Trial (CITT) have helped optometrists develop a diversity of treatment options for patients with binocular vision conditions. ![]() We know more about treating these conditions today than we did 20 years ago thanks, in part, to an increase in binocular vision research. ![]() We recommend bringing them in for a full and thorough eye examination to nip any vision issues in the bud, as some can be rectified with vision exercises to strengthen the eye muscles rather than a prescription for glasses.įill out the form below to enquire about vision training for you or your child.Binocular vision problems should not frighten optometrists-many of these conditions are relatively easy to diagnose and manage. If your child has reported any issues with seeing what they need to see at school, Visique Rose Optometrists can help. Traditionally it has been thought that stereopsis was set in stone by age 13, but we now know that is is in fact possible to improve 3D vision beyond this age.Īt Visique Rose Optometrists, we offer vision therapy or vision training exercises for those that are having trouble with seeing in 3D. Stereopsis is essentially the way that we calculate the depth of a picture or scene we are looking at, and filmmakers use this ability when making 3D television and movies. Our eyes’ ability to see in 3D is governed by a principle called stereopsis. Some people are born with or develop muscular issues which can turn one eye away from the desired direction, affecting binocular focus. Binocular vision is achieved by two eyes working together, viewing images from slightly different angles and overlapping them to create one 3D picture.
