Vision Therapy Clinic - Vision Rehabilitation
Vision is the complex process that gives you your sense of sight.
The human senses are our contact to the environment. The human brain combines the fireworks of neurons of seeing, hearing, smelling, tasting, and touching into a meaningful whole. . We perceive up to 80 percent of all impressions by means of our sight.All our senses give us information about our surroundings but the one we rely most is vision.
Vision therapy clinic
Vision therapy is an evidence-based treatment of strabismic and non-strabismic binocular vision dysfunctions, amblyopia, accommodative, oculomotor, visual processing, and visual-motor integration dysfunction
Clinical research in neuroscience is advancing our understanding of brain plasticity at any age, along with new therapeutic applications of highly motivating, patient-engaging vision-therapy computer-based programs evolving to the next generation, including virtual reality (VR).
In addition to proper application of prescription lenses, prisms, and filters, using advanced methods of office-based vision therapy, including VR programs, can have a positive effect on patient outcomes in their vision rehabilitation treatment plan.
Low Vision Clinic
A common phrase used in the world of ophthalmology is “low vision.”
Used to describe individuals whose eyesight deficiencies cannot be corrected by eyeglasses, it is estimated that 285 million people around the world are living with blindness or visual impairments.
Understanding what low vision is, what causes it, and what can be done to mitigate it is important.
What is lowvision?
Low vision is a condition that can be caused by eye disease, in which visual acuity is 20/70 or poorer in the better-seeing eye and cannot be corrected or improved with regular eyeglasses, surgery or medical intervention.. It can develop at any ageThose with low vision or vision impairment — see only blackness or being completely blind is incorrect. In fact, fewer than 1 percent of those with blindness have no light perception, so it is important to help them make the best use of the remaining vision.
Vision is made up of two parts — acuity and contrast sensitivity. Acuity is the ability to see detail in small or distant objects. The classic eye chart in your optometrist’s office measures acuity. The smaller row of letters you can read, the higher your visual acuity.
Contrast sensitivity is your ability to distinguish an object from its background. The more subtle distinctions in colors or shades you can observe, the higher your contrast sensitivity.
What Causes Low Vision?
Most common causes of low vision include :
Age Related Macular Degeneration
Diabetes
Glaucoma
Low vision may also result from :
Amblyopia [ Lazy Eye]
Retinopathy of Prematurity (ROP)
Retinal detachment
Cancer of the Eye
Albinism
Brain Injury
Cortical/Cerebral Visual Impairment
Inherited genetic disorders of the eye such as retinitis pigmentosa and Leber congenital amaurosis
The number of individuals diagnosed with low vision continues to increase.As people are living longer, we are seeing vision impairment become more prevalent.
The most frequently used Devices:
Low-vision Optical Devices
(MagnifierAs, Telescopes)
Nonoptical devices (bold-lined paper, typoscope, etc.)
Digital Optical Devices Electronic
(video) Magnification
Computer Assistive Devices
Orientation and Mobility aids& activities of daily living aids.
Recently smartphones and tabletshave become accessible to both blind and low-vision individuals. This technology is a revolution in communication, reading, and mobility because a single device is able to provide large print and/or text-to-
speech, global positioning, and interactive maps that facilitate independence as well as offering many other features.
Loss of vision will require a period of training, adaptation and the learning of new skill. During this period the person is likely to require help from another person several times a day with a range of activities
OT Interventions
Increase background contrast
\
Use black on white
\
Or apply bright colors (e.g., markers, tape)
Increase illumination
\
Using different types of light sources, placement, and wattage (higher is better)
\
Without increasing glare
\
Beware of casting shadows
Reduce background pattern
\
Use solid colors instead of background surfaces
\
Reduce clutter in general
Enlarge objects and features
\
Print instructions in larger print
\
Relabel frequently used objects, e.g. medications, calendars
\
Encourage use of magnifiers
\
Change computer and electronics accessibility settings for low vision
Reorganize
\
Store or place frequently used items at a convenient eye level
\
Store less frequently used items lower or higher
\
Encourage clients to keep items organized
\
Put items back where they belong
\
Establish habits and routines to prevent tasks from becoming overwhelming
\
Modify tasks to reduce the number of steps or its complexity
Other Interventions
\
Ensure adaptations such as glasses are used and kept clean
\
Warm water and soap work well to clean glasses
\
Use sunglasses for bright sunlight and light changes between environments
\
Minimize and remove fall hazards, e.g., phone charging cords
\
Address psychosocial factors including social isolation, depression, anxiety, substance abuse
\
Enhance other senses (auditory, tactile, olfactory) and use other strategies and assistive technologies to achieve the same function, e.g. Amazon Echo instead of using a light switch
\
Assessment of functional vision, assessment and physiotherapy for multiple disabilities
Vision rehabilitation maximizes visual functioningso the patient can achieve their visual goals which includes both treatment and education, designed to restore maximal function for the individual as well as maximizing independence, sense of well-being, and quality of life. Rehabilitation should be tailored to the individual’s needs.
What to Look for in Vision Rehabilitation Services :
\
A low vision evaluation by an ophthalmologist or optometrist
\
Prescription for devices
\
Rehabilitation training: for reading, writing, shopping, cooking, lighting and glare control
\
Home assessment
\
Mobility services
\
Resources and support groups
Help is available today. Find out from Dr Anilkumar’s Eye Hospital how low-vision rehabilitation can make all the difference in your daily life. Its important to make the most of the eyesight. If its not possible to fix your vision or reverse vision loss its important to learn to adjust to life with limited sight so that doing routine activities is possible without others help (aeh)
Low-vision rehabilitation helps people who cannot accomplish visual tasks with conventional eyeglasses, contact lenses, medication, or through surgical intervention.
A visual impairment can be acquired or congenital. The World Health Organization (WHO) reports that 324 million people worldwide have vision loss [1]. Approximately half of those do not have access to the care that could mitigate their vision loss [1,2], with individuals 50 years of age or more representing the largest age group with vision loss
