Description

Vision Therapy: Good vision requires eyesight, visual pathways, and brain to all work together. When they don’t, even a person with 20/20 eyesight can experience difficulty reading, writing, and processing information. Vision Therapy or Vision Training is the art and science of developing, improving and enhancing visual skills, perception, and performance. Vision therapy combines optometric training through biofeedback design. Vision Therapy is concept which deals with quality & function of vision. Vision therapy is important as 80% of input to brain comes through eyes. Vision therapy helps the patient develop the visual skills necessary for good vision. Optical devices and exercises are used to improve the eye-brain connection in order to make eye movements easier and more efficient. The patient learns how to correctly process the visual information that the brain receives from the eyes. Vision therapy can range from one session to 2-3 months and involves office visits combined with at-home activities. Sankara eye hospitals at Bangalore & Ludhiana are doing Vision therapy for LD and autism. This therapy should be integrated for LD & autistic kids along with other therapies. Vision problems : • Near sightness(difficult to read far target) • Farsightedness(difficulty to read near target) • Astigmatism (unable to see clear ) • Eye coordination problems (inability to coordinate eyes together) • Eye focusing problems(inability to focus the eye on one point) • Difficulty to track the object (inability to move the eyes smooth and inacurate) • Faulty vision form perception(inability to discriminate differences in size, shape, or form) • Faulty visual memory(inability to remember and understand what is seen) • Faulty visual motor integration((inability to process and reproduce visual images by writing or) • Faulty lateralty and directionalty(poor development of left/right awareness) Who needs vision therapy? Patients who require vision therapy generally have the following visual challenges: • Learning-related visual problems: Conditions such as poor eye teaming, focusing, tracking and visualization skills can all negatively affect learning. • Crossed Eye (Strabismus) or Lazy Eye (Amblyopia): Crossed eyes and or lazy eyes can be treated with Vision Therapy instead of conventional surgery, glasses or patching. Vision Therapy is very effective for these conditions at an early age, but can yield results for patients of any age. • Stress-induced vision problems: Our high-tech society requires many people to do a large volume of near work in front of a computer screen. Because of this, there is an increasing number of patients that experience eyestrain, headaches and other visual related difficulties. • Visual rehabilitation for special populations (strokes, brain injuries, developmental delays, multiple sclerosis, etc.): A neurological disorder or trauma to the nervous system can affect a person’s vision. This includes people who have traumatic brain injuries, strokes, whiplash, developmental delays, cerebral palsy, multiple sclerosis, and other neurological ailments. • Sports vision improvement: Even good vision can become better. Athletes often use Vision Therapy to improve eye-hand coordination, visual reaction time, peripheral awareness, eye teaming, focusing, tracking and visualization skills. What outcomes can you expect from vision therapy? When the eyes move, align, fixate and focus together, a whole new world of vision is discovered. With successful treatment, our patients may find that: • Learning becomes easier • Reading level and speed increases • Time spent on homework decreases • The ability to follow moving objects (a ball, a car) improves • Seeing objects nearby or at a distance improves • Visualizing mental images becomes easier The rate at which patients experience these improvements will vary, but generally progress is seen early in the therapy programme Other manageable symptoms are; • Complaints of blurred vision • Squint • Rubs eye frequently • Squint • Close or cover one eye • Hold things very close • Able to read for only a short time • Poor reading comprehension • Says eyes are tired • Has headache when reading • Moved head excessively during reading • Uses finger to keep place • Short attention span • Difficulty to recognizing the letter shapes word • Difficulty in distinguish the details • Trouble in mathemetical concepts Vision therapy can help in following Visual related Disorders: • Amblyopia • Strabismus • Learning related disorders • Dyslexia • Traumatic Brain Injury • Nystagmus • Focusing problems • Autism Spectrum Disorders • ADHD • ADD • Diplopia / Double vision • Headache • Vision stimulations • Slow Learner • Cerebral palsy • Cortical Visual Impairment • Down syndrome • Mental retardation • Computer vision syndrome Vision therapy is safe, drug-free, and effective for both children and adults. Because visual skills such as tracking lines of text, coordinating the eyes, and focusing on close objects must be learned during development, these skills can also be improved later in life at any age. Low vision in Mumbai : Low vision is the term used to describe significant visual impairment that can't be corrected fully with glasses, contact lenses, medication or eye surgery. It includes: • Loss of best-corrected visual acuity (BVCA) to worse than 20/70 in the better eye. • Significant visual field loss. Tunnel vision (lack of vision in the periphery) and blind spots are examples of visual field loss. • Legal blindness. In the United States, legal blindness typically is defined as visual acuity of 20/200 or worse (in the better eye, with the best possible vision correction in place) or a field of view (visual field) that is constricted to 20 degrees or less. Disability statistics from the 2014 American Community Survey show that 2.3 percent of individuals ages 16 and over have a visual disability or low vision. Causes Of Low Vision Eye diseases are a common cause of low vision. For example: • Hazy, blurry vision can result from cataracts. • Blurred or partially obscured central vision is typical of macular degeneration. • Diabetic retinopathy causes blind spots, blurriness and visual distortions. • Poor peripheral vision is a hallmark of glaucoma. • Retinitis pigmentosa reduces peripheral vision and the ability to see in the dark. • Light sensitivity and loss of contrast are other symptoms of these and other diseases. • Heredity and eye injuries can result in low vision. The Impact Of Low Vision Children can have low vision due to a birth defect or injury. Visually impaired children may have learning problems that require special instruction and they may need help developing socialization skills. You can use the versatile Acrobat LCD video magnifier from Enhanced Vision for reading, writing and self-viewing. Vision loss in adults and seniors can be particularly traumatic, leading to frustration and depression. Losing the ability to drive safely, read quickly, watch television or view a computer screen can cause people with low vision to feel shut off from the world. They may be unable to get around town independently or shop for food and other necessities. Many people with low vision also have difficulty making a living, as the following statistics from the U.S. Census Bureau's American Community Survey of 2010 illustrate: • The employment rate for visually disabled Americans ages 21-64 (working age) was only 37.2 percent in 2010. The full-time/full-year employment rate was 24 percent. And of those without a job, only 13.5 percent were actively looking for work. • Individual poverty rates were 29.5 percent for visually disabled people vs. 11.9 percent of those with no disability. Some visually impaired people become very dependent on friends and relatives, while others suffer alone. That's a shame, because many ingenious low vision devices are available to help people overcome vision impairment and live independently. What To Do About Low Vision If you have a vision impairment that interferes with your ability to perform everyday activities and enjoy life, your first step is to see an eye care professional for a complete eye exam. Poor vision that cannot be corrected with eyeglasses or contact lenses could be the first sign of a serious eye disease such as age-related macular degeneration, glaucoma or retinitis pigmentosa. Or it could mean you are developing a cataract that needs removal. Whatever the case, it's wise to take action before further vision loss occurs. If your eye doctor finds that you have vision loss that cannot be corrected adequately with standard eyewear, medical treatment or surgery, he or she will help you take the next steps toward coping with your new situation. An eye doctor who doesn't work in the low vision arena would refer you to a low vision specialist. A low vision specialist can evaluate the degree and type of vision loss you have, prescribe appropriate low vision aids such as lighted handheld magnifiers, digital desktop magnifiers and bioptic telescopes, and help you learn how to use them. Newer options include handheld digital magnifiers for shopping or eating out, as well as software that simplifies computer use with magnification and text-to-speech features. The low vision specialist also can recommend non-optical adaptive devices, such as large-face printed material, audio recordings, special light fixtures and signature guides for signing checks and documents. Special eyewear with tinted UV filters can help with light sensitivity and heighten contrast. If necessary, your specialist or eye doctor also can refer you to a mental health professional and/or mobility coach to help you cope with your vision loss. CONTACT LENS IN MUMBAI Contact lens: We are providing all types of contact lenses eg. Soft, RGP ,ROSE -K ,SCLERAL ,MINI- SCLERAL SCLERAL CONTACT LENS : HELP TO REDUCE KERATOCONNUS X-CHROME CONTACT LENSES :It helps to develop the color vision . Bifocal Contact Lenses/MULTIFOCAL Bifocal contact lenses are designed to give good vision to people who have a condition called presbyopia. The key sign that you’re developing presbyopia is that you need to hold reading material, like a menu or newspaper, farther from your eyes to see it clearly. Bifocal contact lenses are available in both soft and rigid gas permeable (GP) materials, and some can be worn on a disposable basis. That means you can have the convenience of throwing the lenses out at specified intervals (even daily, in some cases) and replacing them with fresh, new lenses. Also, one bifocal brand is available in silicone hydrogel material. RGP Contact Lens Rigid gas permeable contact lenses, also called RGP or GP contact lenses, are made from a firm plastic material and contain no water. Unlike hard lenses, RGP lenses permit oxygen to pass directly through the lens to the eye so that it may “breathe.” Because they transmit oxygen these lenses are referred to as gas permeable. RGP lenses are custom made, they can be designed to fit your eye exactly. Chandra KC Lenses The Chandra Scleral Lens, a highly oxygen permeable rigid (120 DK) contact lens device the size of a 50 paisa, is designed to rest on the tough relatively insensitive tissue of the eye called the sclera. By enclosing an artificial tear-filled space over the diseased cornea, the most sensitive tissue of the human body, it functions as a soothing and healing liquid bandage that relieves the pain and light sensitivity of severe dry eyes and chronic corneal inflammation while encouraging the healing of erosions and ulcers even when all other treatments have failed.)
