Visual impairment, also known as vision impairment or vision loss, is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses. Visual impairment is often defined as a best-corrected visual acuity of worse than either 20/40 or 20/60. Rates of visual impairment have decreased since the 1990s. Visual impairments have considerable economic costs both directly due to the cost of treatment and indirectly due to decreased ability to work. However, Siddha Spirituality of Swami Hardas Life System brings out here some Siddha remedies, which can be applied easily at home for well-being.
Definition of Visual impairment
The definition of visual impairment is reduced vision not corrected by glasses or contact lenses.
Meaning of blindness
The term blindness is used for complete or nearly complete vision loss. Visual impairment may cause difficulties with normal daily activities such as reading and walking without adaptive training and equipment.
Definition of blindness
Blindness is defined by the World Health Organization as a vision in a person’s best eye with the best correction of less than 20/500 or a visual field of fewer than 10 degrees. This definition was set in 1972, and there is an ongoing discussion as to whether it should be altered to officially include uncorrected refractive errors.
Visual impairment Classification
The World Health Organization uses the following classifications of visual impairment. When the vision in the better eye with best possible glasses correction is:
- 20/30 to 20/60: is a mild vision loss or near-normal vision,
- 20/70 to 20/160: is a moderate visual impairment or moderate low vision,
- 20/200 to 20/400: is a severe visual impairment or severe low vision,
- 20/500 to 20/1,000: is profound visual impairment or profound low vision,
- More than 20/1,000: is a near-total visual impairment or near-total blindness,
- No light perception (NLP): is considered a total visual impairment, or total blindness.
Visual impairment Cause
Common causes of visual impairment
The most common causes of visual impairment globally in 2010 were:
- Refractive error (42%)
- Cataract (33%)
- Glaucoma (2%)
- Age-related macular degeneration (1%)
- Corneal opacification (1%)
- Diabetic retinopathy (1%)
- Childhood blindness
- Trachoma (1%)
- Undetermined (18%)
Common causes of blindness
The most common causes of blindness worldwide in 2010 were:
- Cataracts (51%)
- Glaucoma (8%)
- Age-related macular degeneration (5%)
- Corneal opacification (4%)
- Childhood blindness (4%)
- Refractive errors (3%)
- Trachoma (3%)
- Diabetic retinopathy (1%)
- Undetermined (21%)
About 90% of people who are visually impaired live in the developing world. Age-related macular degeneration, glaucoma, and diabetic retinopathy are the leading causes of blindness in the developed world.
Working-age adults causes of blindness
Among working-age adults who are newly blind in England and Wales the most common causes in 2010 were:
- Hereditary retinal disorders (20.2%)
- Diabetic retinopathy (14.4%)
- Optic atrophy (14.1%)
- Glaucoma (5.9%)
- Congenital abnormalities (5.1%)
- Disorders of the visual cortex (4.1%)
- Cerebrovascular disease (3.2%)
- Degeneration of the macula and posterior pole (3.0%)
- Myopia (2.8%)
- Corneal disorders (2.6%)
- Malignant neoplasms of the brain and nervous system (1.5%)
- Retinal detachment (1.4%)
Cataracts: Leading cause of Visual impairment
Cataracts are the leading cause of child and adult blindness that doubles in prevalence every ten years after the age of 40. Consequently, today cataracts are more common among adults than in children. That is, people face higher chances of developing cataracts as they age.
Nonetheless, cataracts tend to have a greater financial and emotional toll upon children as they must undergo expensive diagnosis, long-term rehabilitation, and visual assistance.
Glaucoma: Leading cause of Visual impairment
Glaucoma is a congenital and pediatric eye disease characterized by increased pressure within the eye or intraocular pressure (IOP). Glaucoma causes visual field loss as well as severs the optic nerve. Early diagnosis and treatment of glaucoma in patients are imperative because glaucoma is triggered by non-specific levels of IOP.
Challenge in accurately diagnosing
Also, another challenge in accurately diagnosing glaucoma is that the disease has four causes:
- Inflammatory ocular hypertension syndrome (IOHS);
- Severe uveitic angle closure;
- Corticosteroid-induced; and
- A heterogonous mechanism associated with structural change and chronic inflammation.
In addition, often pediatric glaucoma differs greatly in cause and management from glaucoma developed by adults. Currently, the best sign of pediatric glaucoma is an IOP of 21 mm Hg or greater present within a child.
Infections: Leading cause of Visual impairment
Childhood blindness can be caused by conditions related to pregnancy, such as congenital rubella syndrome and retinopathy of prematurity. Leprosy and onchocerciasis each blind approximately 1 million individuals in the developing world.
The number of individuals blind from trachoma has decreased in the past 10 years from 6 million to 1.3 million, putting it in seventh place on the list of causes of blindness worldwide.
Central corneal ulceration is also a significant cause of monocular blindness worldwide, accounting for an estimated 850,000 cases of corneal blindness every year in the Indian subcontinent alone.
Injuries: Leading cause of Visual impairment
Eye injuries, most often occurring in people under 30, are the leading cause of monocular blindness (vision loss in one eye) throughout the United States. Injuries and cataracts affect the eye itself, while abnormalities such as optic nerve hypoplasia affect the nerve bundle that sends signals from the eye to the back of the brain, which can lead to decreased visual acuity.
Cortical blindness results from injuries to the occipital lobe of the brain that prevents the brain from correctly receiving or interpreting signals from the optic nerve. Symptoms of cortical blindness vary greatly across individuals and may be more severe in periods of exhaustion or stress.
Genetic defects: Leading cause of Visual impairment
People with albinism often have vision loss to the extent that many are legally blind, though few of them actually cannot see. Leber congenital amaurosis can cause total blindness or severe sight loss from birth or early childhood.
Recent advances in mapping the human genome have identified other genetic causes of low vision or blindness. One such example is Bardet–Biedl syndrome.
Poisoning: Leading cause of Visual impairment
Rarely, blindness is caused by the intake of certain chemicals. A well-known example is methanol, which is only mildly toxic and minimally intoxicating, and breaks down into the substances formaldehyde and formic acid which in turn can cause blindness, an array of other health complications, and death.
Other leading causes of Visual impairment
It is the condition when a child’s visual systems fail to mature normally because the child either suffers from premature birth, measles, congenital rubella syndrome, vitamin A deficiency, or meningitis.
If left untreated during childhood, amblyopia is currently incurable in adulthood because surgical treatment effectiveness changes as a child mature.
Corneal opacity is a disorder of the cornea. The cornea is the transparent structure on the front of the eyeball. Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina and may cause the cornea to appear white or clouded over.
It is a condition whereby images come into focus in front of the eye, resulting in a blurred image on the retina. The more severe the nearsightedness, the farther the image is from the retina, which results in more blurry vision in the distance.
Myopia causes light rays to focus on the front of the retina. As a result, close objects are seen clearly, while distant objects appear blurred. Near vision, however, can deteriorate to a level where reading even close to the face can become difficult.
It is one of the manifestation microvascular complications of diabetes, which is characterized by blindness or reduced acuity. That is, diabetic retinopathy describes the retinal and vitreous hemorrhages or retinal capillary blockage caused by the increase of A1C, which is a measurement of blood glucose or sugar level.
In fact, as A1C increases, people tend to be at greater risk of developing diabetic retinopathy than developing other microvascular complications associated with diabetes e.g. chronic hyperglycemia, diabetic neuropathy, and diabetic nephropathy.
Retinitis pigmentosa (RP) is a group of rare, genetic disorders that involve a breakdown and loss of cells in the retina — which is the light-sensitive tissue that lines the back of the eye. Common symptoms include difficulty seeing at night and a loss of side (peripheral) vision.
Retinopathy of prematurity
The most common cause of blindness in infants worldwide. In its most severe form, ROP causes retinal detachment, with attendant visual loss.
Stargardt disease is an eye disease that causes vision loss in children and young adults.
Stargardt disease is often called juvenile macular dystrophy. In people with Stargardt disease, special light-sensing cells in the macula, called photoreceptors, die off. Central or detailed, vision becomes blurry or has dark areas. It may also be difficult to see colors well.
It is a group of 30 intraocular inflammatory diseases caused by infections, systemic diseases, organ-specific autoimmune processes, cancer, or trauma. That is, uveitis refers to a complex category of ocular diseases that can cause blindness if either left untreated or improperly diagnosed.
Xerophthalmia, often due to vitamin A deficiency, is estimated to affect 5 million children each year; 500,000 develop active corneal involvement, and half of these go blind.
Visual impairment Diagnosis
It is important that people be examined by someone specializing in low vision care prior to other rehabilitation training to rule out a potential medical or surgical correction for the problem and to establish careful baseline refraction and prescription of both normal and low vision glasses and optical aids.
Only a doctor is qualified to evaluate the visual functioning of a compromised visual system effectively.
Visual impairment Prevention
The World Health Organization estimates that 80% of visual loss is either preventable or curable with treatment. This includes cataracts, onchocerciasis, trachoma, glaucoma, diabetic retinopathy, uncorrected refractive errors, and some cases of childhood blindness. The Center for Disease Control and Prevention estimates that half of the blindness in the United States is preventable.
Some tips of how to prevent Visual impairment
During a comprehensive dilated eye exam, your eye care professional place drops in your eyes to dilate, or widen, the pupil to allow more light to enter the eye—the same way an open door lets more light into a dark room. This process enables your eye care professional to get a good look at the back of the eyes and examine them for any signs of damage or disease. Your eye care professional is the only one who can determine if your eyes are healthy and if you’re seeing your best.
Maintain your blood sugar levels
90% of blindness caused by diabetes is preventable. Ask your health care team to help you set and reach goals to manage your blood sugar, blood pressure, and cholesterol—also known as the ABCs of diabetes.
- A1c: The goal set for many people is less than 7% for this blood test, but your doctor might set different goals for you.
- Blood pressure: High blood pressure causes heart disease. The goal is less than 140/90 mmHg for most people, but your doctor might set different goals for you.
- Cholesterol: LDL or “bad” cholesterol builds up and clogs your blood vessels. HDL or “good” cholesterol helps remove the “bad” cholesterol from your blood vessels.
Know your family’s eye health history
Talk to your family members about their eye health history. This information will help to determine if you’re at higher risk for developing an eye disease or condition.
Eat right to protect your sight
You’ve heard that carrots are good for your eyes. But eating a diet rich in fruits and vegetables—particularly dark leafy greens, such as spinach, kale, or collard greens—is important for keeping your eyes healthy, too. Research has also shown there are eye health benefits from eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut.
Maintain a healthy weight
Wear protective eyewear
Wear protective eyewear when playing sports or doing activities around the home. Protective eyewear includes safety glasses and goggles, safety shields, and eye guards specially designed to provide the correct protection for the activity in which you’re engaged.
Quit smoking or never start
Smoking is as bad for your eyes as it is for the rest of your body. Research has linked smoking to an increased risk of developing age-related macular degeneration, cataract, and optic nerve damage, all of which can lead to blindness.
Be cool and wear your shades
Sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun’s ultraviolet rays. When purchasing sunglasses, look for ones that block out 99 to 100 percent of both UV-A and UV-B radiation.
Give your eyes a rest
Try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This short exercise can help reduce eyestrain.
Clean your hands and your contact lenses
To avoid the risk of infection, always wash your hands thoroughly before putting in or taking out your contact lenses. Make sure to disinfect contact lenses as instructed and replace them as appropriate.
Visual impairment Management
Many people with serious visual impairments can travel independently, using a wide range of tools and techniques.
The professionals can also help blind people to practice traveling on specific routes which they may use often, such as the route from one’s house to a convenience store. Becoming familiar with an environment or route can make it much easier for a blind person to navigate successfully.
Reading and magnification
Many also read large-print, which is easier for them to read without such devices. A variety of magnifying glasses, some handheld, and some on desktops, can make reading easier for them.
Others read Braille (or the infrequently used Moon type) or rely on talking books and readers or reading machines, which convert printed text to speech or braille. There are also over 100 radio reading services throughout the world that provide people with vision impairments with readings from periodicals over the radio. The International Association of Audio Information Services provides links to all of these organizations.
Computers and mobile technology
Access technology such as screen readers, screen magnifiers, and refreshable braille displays enable the blind to use mainstream computer applications and mobile phones. The availability of assistive technology is increasing, accompanied by concerted efforts to ensure the accessibility of information technology to all potential users, including the blind.
Experimental approaches in sensory substitution are beginning to provide access to arbitrary live views from a camera.
Health effects of Visual impairment
Forms of visual impairment
Visual impairments may take many forms and be of varying degrees. Visual acuity alone is not always a good predictor of the degree of problems a person may have. Someone with relatively good acuity (e.g., 20/40) can have difficulty with daily functioning, while someone with worse acuity (e.g. 20/200) may function reasonably well if their visual demands are not great.
The American Medical Association has estimated that the loss of one eye equals 25% impairment of the visual system and 24% impairment of the whole person; total loss of vision in both eyes is considered to be 100% visual impairment and 85% impairment of the whole person.
Some people who fall into this category can use their considerable residual vision – their remaining sight – to complete daily tasks without relying on alternative methods. The role of a low vision specialist (optometrist or ophthalmologist) is to maximize the functional level of a patient’s vision by optical or non-optical means.
Primarily, this is by use of magnification in the form of telescopic systems for distance vision and optical or electronic magnification for near tasks.
People with significantly reduced acuity may benefit from training conducted by individuals trained in the provision of technical aids. Low vision rehabilitation professionals, some of whom are connected to an agency for the blind, can provide advice on lighting and contrast to maximize remaining vision.
These professionals also have access to non-visual aids and can instruct patients in their uses.
Highest level of social integration
The subjects making the most use of rehabilitation instruments, who lived alone, and preserved their own mobility and occupation were the least depressed, with the lowest risk of suicide and the highest level of social integration.
High risk of suicide
Those with worsening sight and the prognosis of eventual blindness are at comparatively high risk of suicide and thus may be in need of supportive services.
Many studies have demonstrated how rapid acceptance of the serious visual handicap has led to a better, more productive compliance with rehabilitation programs.
Therefore, early intervention is imperative for enabling successful psychological adjustment.
Associated conditions of Visual impairment
Blindness can occur in combination with such conditions as:
- Intellectual disability,
- Autism spectrum disorders,
- Cerebral palsy,
- Hearing impairments, and
Blindness in combination with hearing loss is known as deafblindness.
It has been estimated that over half of completely blind people have non-24-hour sleep-wake disorder, a condition in which a person’s circadian rhythm, normally slightly longer than 24 hours, is not entrained (synchronized) to the light-dark cycle.
Siddha remedies for Visual impairment
