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. The term blindness is used for complete or nearly complete vision loss. Visual impairment may cause people difficulties with normal daily activities such as driving, reading, socializing, and walking.
The most common causes of visual impairment:
- refractive errors (42%)
- cataracts (33%)
- glaucoma (2%)
- age related macular degeneration (1%)
- corneal opacification (1%)
- diabetic retinopathy (1%)
- childhood blindness
- trachoma (1%)
- undetermined (18%)
Glaucoma is an eye condition that damages your optic nerve. Learn what causes it.
Making Sense of Hypertensive Retinopathy
High blood pressure can damage the retina's blood vessels and limit the retina's function. It can also put pressure on the optic nerve.
A cataract is a dense, cloudy area that forms in the lens of the eye. It develops slowly and eventually interferes with your vision.
Age-Related Macular Degeneration (AMD)
Macular degeneration is a common eye disorder that causes central vision loss. Learn more about it.
Diabetic retinopathy is a condition that occurs as a result of damaged blood vessels of the retina in people who have diabetes. Diabetic retinopathy can develop whether you have type 1 or type 2 diabetes.8
Retinal Vascular Occlusion
Retinal vascular occlusion occurs when one of the vessels carrying blood to or from your retina becomes blocked or contains a blood clot.
A stroke (a "brain attack") is a medical emergency in which part of the brain is deprived of oxygen. This occurs when an artery that supplies oxygenated blood to the brain becomes damaged and brain cells begin to die.
The optic nerve carries visual information from your eye to your brain. Optic neuritis (ON) is when your optic nerve becomes inflamed, causing vision loss.
Strabismus is a disorder in which the eyes do not line up in the same direction. People with strabismus cannot look at the same object or place with both eyes at the same time.
Intracranial hemorrhage (ICH) is bleeding inside the skull. It is a life-threatening emergency.
Subarachnoid hemorrhage (SAH) refers to bleeding within the subarachnoid space, which is the area between your brain and the tissues that cover it.
An aneurysm in the brain is a weak area in an artery in the brain that bulges out and fills with blood. It can be unpredictable and life-threatening, and can cause extremely serious conditions.
Homeopathy is a wonderful method for treating vision loss. If the correct medicine is chosen, croup can resolve very rapidly. As with all homeopathic treatments, the goal is to identify the simillimum, the remedy that most closely matches the patient’s presenting symptoms and mental-emotional state. The power of homeopathy for treating vision loss is out of proportion to the expectation.
Retinal detachment is a very serious eye condition that happens when the retina separates from the tissue around it. Since the retina can't work properly under these conditions, you could permanently lose vision if the detached retina isn't repaired promptly.
Who's at Risk for a Detached Retina?
The following factors increase your risk of retinal detachment:
- Aging — retinal detachment is more common in people over age 50
- Previous retinal detachment in one eye
- A family history of retinal detachment
- Extreme nearsightedness (myopia)
- Previous eye surgery, such as cataract removal
- Previous severe eye injury
- Previous other eye disease or inflammation
Rhegmatogenous retinal detachment – A rhegmatogenous retinal detachment occurs due to a break in the retina (called a retinal tear) that allows fluid to pass from the vitreous space into the subretinal space between the sensory retina and theretinal pigment epithelium. Retinal breaks are divided into three types – holes, tears and dialyses. Holes form due to retinal atrophy especially within an area of lattice degeneration. Tears are due to vitreoretinal traction. Dialyses are very peripheral and circumferential, and may be either tractional or atrophic. The atrophic form most often occurs as idiopathic dialysis of the young.
- Exudative, serous, or secondary retinal detachment – An exudative retinal detachment occurs due to inflammation, injury or vascular abnormalities that results in fluid accumulating underneath the retina without the presence of a hole, tear, or break. In evaluation of retinal detachment it is critical to exclude exudative detachment as surgery will make the situation worse, not better. Although rare, exudative detachment can be caused by the growth of a tumor on the layers of tissue beneath the retina, namely the choroid. This cancer is called a choroidal melanoma.
- Tractional retinal detachment – A tractional retinal detachment occurs when fibrous or fibrovascular tissue, caused by an injury, inflammation or neovascularization, pulls the sensory retina from the retinal pigment epithelium.
A rhegmatogenous retinal detachment is commonly preceded by a posterior vitreous detachment which gives rise to these symptoms:
- flashes of light (photopsia) – very brief in the extreme peripheral (outside of center) part of vision
- a sudden dramatic increase in the number of floaters
- a ring of floaters or hairs just to the temporal (skull) side of the central vision
Although most posterior vitreous detachments do not progress to retinal detachments, those that do produce the following symptoms:
- a dense shadow that starts in the peripheral vision and slowly progresses towards the central vision
- the impression that a veil or curtain was drawn over the field of vision
- straight lines (scale, edge of the wall, road, etc.) that suddenly appear curved (positive Amsler grid test)
- central visual loss
Retinal detachment can be examined by fundus photography or ophthalmoscopy.
Homeopathy is a wonderful method for treating retinal detachment. If the correct medicine is chosen, croup can resolve very rapidly. As with all homeopathic treatments, the goal is to identify the simillimum, the remedy that most closely matches the patient’s presenting symptoms and mental-emotional state. The power of homeopathy for treating retinal detachment is out of proportion to the expectation.
Crohn's disease is a type of inflammatory bowel disease (IBD) that may affect any part of the gastrointestinal tract from mouth to anus. Signs and symptoms often include abdominal pain, diarrhea (which may be bloody if inflammation is severe), fever, and weight loss. Other complications may occur outside the gastrointestinal tract and include anemia, skin rashes, arthritis, inflammation of the eye, and feeling tired. The skin rashes may be due to infections as well as pyoderma gangrenosum or erythema nodosum. Bowel obstruction also commonly occurs and those with the disease are at greater risk of bowel cancer
It tends to start in the teens and twenties, although it can occur at any age, the terminal ileum of the small intestine, the area most commonly affected by the illness. Males and females are equally affected.
While the exact cause is unknown, Crohn's disease seems to be due to a combination of environmental factors and genetic predisposition, the chronic inflammation of Crohn's is caused when the adaptive immune system tries to compensate for a deficient innate immune system.
- Genetics - Crohn's has a genetic component. Because of this, siblings of known people with Crohn's are 30 times more likely to develop Crohn's than the general population.
- Immune system - There was a prevailing view that Crohn's disease is a primary T cell autoimmune disorder, however, a newer theory hypothesizes that Crohn's results from an impaired innate immunity.
- Microbes - Current thinking is that microorganisms are taking advantage of their host's weakened mucosal layer and inability to clear bacteria from the intestinal walls, which are both symptoms of Crohn's .
- Environmental factors - Crohn's is associated with an increased intake of animal protein, milk protein and an increased ratio of omega-6 to omega-3 polyunsaturated fatty acids. Those who consume vegetable proteins appear to have a lower incidence of Crohn's disease. Consumption of fish protein has no association. Smoking increases the risk of the return of active disease (flares). Although stress is sometimes claimed to exacerbate Crohn's disease, there is no concrete evidence to support such claim. Dietary microparticles, such as those found in toothpaste, have been studied as they produce effects on immunity, but they were not consumed in greater amounts in patients with Crohn's.
SIGNS AND SYMPTOMS
In some people with Crohn's disease, only the last segment of the small intestine (ileum) is affected. In others, the disease is confined to the colon (part of the large intestine). The most common areas affected by Crohn's disease are the last part of the small intestine and the colon.
When the disease is active, signs and symptoms may include:
- Diarrhea. Diarrhea is a common problem for people with Crohn's disease. Intensified intestinal cramping also can contribute to loose stools.
- Fever and fatigue. Many people with Crohn's disease experience a low-grade fever, likely due to inflammation or infection. You may also feel tired or have low energy.
- Abdominal pain and cramping. Inflammation and ulceration can affect the normal movement of contents through your digestive tract and may lead to pain and cramping. You may experience anything from slight discomfort to severe pain, including nausea and vomiting.
- Blood in your stool. You might notice bright red blood in the toilet bowl or darker blood mixed with your stool. You can also have bleeding you don't see (occult blood).
- Mouth sores. You may have ulcers in your mouth similar to canker sores.
- Reduced appetite and weight loss. Abdominal pain and cramping and the inflammatory reaction in the wall of your bowel can affect both your appetite and your ability to digest and absorb food.
- Perianal disease. You might have pain or drainage near or around the anus due to inflammation from a tunnel into the skin (fistula).
Other signs and symptoms
People with severe Crohn's disease may also experience:
- Inflammation of skin, eyes and joints
- Inflammation of the liver or bile ducts
- Delayed growth or sexual development, in children
- Bowel obstruction
- Anal fissure
- Colon cancer
- Other health problems - anemia, osteoporosis, and gallbladder or liver disease.
- Medication risks - Certain Crohn's disease drugs that act by blocking functions of the immune system are associated with a small risk of developing cancers such as lymphoma and skin cancers. They also increase risk of infection.
Homeopathy is one of the most popular holistic systems of medicine. The selection of remedy is based upon the theory of individualization and symptoms similarity by using holistic approach. This is the only way through which a state of complete health can be regained by removing all the sign and symptoms from which the patient is suffering. The aim of homeopathy is not only to treat Crohn’s disease symptoms but to address its underlying cause and individual susceptibility. As far as therapeutic medication is concerned, several well-proved medicines are available for Crohn’s disease treatment that can be selected on the basis of cause, condition, sensation and modalities of the complaints. For individualized remedy selection and treatment, the patient should consult a qualified homeopathic doctor in person.
Conjunctivitis, also known as pinkeye, is an inflammation of the conjunctiva. The conjunctiva is the thin clear tissue that lies over the white part of the eye and lines the inside of the eyelid. Typical symptoms exhibited by all patients include reddened eyes and sticky eyelids in the morning due to increased secretion. If the patient has not experienced pain or blurred vision, conjunctivitis is a likely diagnosis. Treatment for conjunctivitis varies with the cause
Conjunctivitis can be caused by virus, bacteria, virus , allergies like dust, pollen, irritation from pollutants, windburn, or exposure to too much sun, Chlamydia, Fungi, Parasites (rarely) and Use of contact lenses (especially extended-wear lenses) .
Newborns can be infected by bacteria in the birth canal. This condition is called ophthalmia neonatorum. It must be treated at once to preserve eyesight.
Symptoms of Pinkeye
The symptoms of pinkeye differ based on the cause of the inflammation, but may include:
- Redness in the white of the eye or inner eyelid
- Increased amount of tears
- Thick yellow discharge that crusts over the eyelashes, especially after sleep
- Green or white discharge from the eye
- Itchy eyes
- Burning eyes
- Blurred vision
- Increased sensitivity to light
The symptoms usually develop within 24 to 72 hours of becoming infected and last from two days to three weeks. Conjunctivitis can be transmitted from an infected mother to her baby during vaginal delivery.
It can be classified into two types:
A] Infectious conjunctivitis:
Infectious conjunctivitis is either bacterial or viral in origin and spreads to the other eye when one eye is infected. It also spreads to people coming in contact with the affected person.
B] Non-infectious conjunctivitis:
Non-infectious conjunctivitis occurs due to pollen or some foreign body or pollutants or dust or household cleaners, smoke, entering the eye, underlying diseases like rheumatoid arthritis, cytomegalovirus, lupus, Kawasaki's disease, Ulcerative Colitis, Crohn's Disease. It does not spread. Herpes can also cause non-infectious conjunctivitis. Chemical conjunctivitis is caused due to burns and exposure to toxic chemicals. Allergic conjunctivitis is accompanied by irritation and discharge from the nose.
Homoeopathy for Pinkeye
Homeopathy has great scope in the treatment of conjunctivitis. Homeopathic remedies can help to reduce inflammation and ease discomfort in conjunctivitis. The biggest plus point in homoeopathy is that their success is attained by employing the constitutional remedy internally. Homoeo medicines will help to relieve inflammation and ease the pain. Homoeopathy considers an individual as a whole and thereby a detailed history of the patient is taken to find out the constitutional similimum. Medicines help to boost your immune system and help to prevent further progression and reoccurrence of the disease.
Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye.
Glaucoma tends to be inherited and may not show up until later in life.
Glaucoma usually occurs when pressure in your eye increases. This can happen when eye fluid isn't circulating normally in the front part of the eye. Normally, this fluid, called aqueous humor, flows out of the eye through a mesh-like channel. If this channel becomes blocked, fluid builds up, causing glaucoma. If you having a strong Family history of glaucoma or are at a risk of other eye diseases or diabetes you should check your eye pressure.
Glaucoma most often occurs in adults over age 40, but it can also occur in young adults, children, and even infants.
- Have a family history of glaucoma
- Have poor vision
- Have diabetes
- Take certain steroid medications, such as prednisone
- Have had trauma to the eye or eyes
What Are the Types of Glaucoma?
There are two main types of glaucoma:
Also called wide-angle glaucoma, this is the most common type of glaucoma. The structures of the eye appear normal, but fluid in the eye does not flow properly through the drain of the eye, called the trabecular meshwork.
- Patchy blind spots in your side (peripheral) or central vision, frequently in both eyes
- Tunnel vision in the advanced stages
Also called acute or chronic angle-closure or narrow-angle glaucoma, this type of glaucoma is less common in the West than in Asia. Poor drainage is caused because the angle between the iris and the cornea is too narrow and is physically blocked by the iris. This condition leads to a sudden buildup of pressure in the eye.
- Severe headache
- Eye pain
- Nausea and vomiting (accompanying severe eye pain)
- Blurred vision
- Halos around lights
- Eye redness
- Sudden sight loss
If left untreated, glaucoma will eventually cause blindness. Even with treatment, about 15 percent of people with glaucoma become blind in at least one eye within 20 years.
How homoeopathy helps???
Homoeopathy shows wonderful results in managing glaucoma. The treatment prevents damage to the optic nerve if detected early and reduces the eyepains, redness and improves the blood supply to the eyes. Many medicines are there for the problem and for each person the medicine varies. Medicines are prescribed based on a detailed case taking which includes history of the patient, physical, mental plane and genetic predisposition. There will not be any toxic effects of medicine and it will boost up your immune system preventing its progression and reoccurrence.
A cataract is a clouding of the lens in the eye leading to a decrease in vision. It can affect one or both eyes. Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world. Cataracts happen when protein builds up in the lens of your eye, making it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. New lens cells form on the outside of the lens, and the older cells are compacted into the center of the lens, forming the cataract. Other things that can raise your risk of getting cataracts include cigarette smoke, air pollution, and heavy drinking.
Types Of Cataracts Include:
- Age-related cataracts. These cataracts form because of of aging.
- Congenital cataracts. Babies are sometimes born with cataracts as a result of an infection, injury, or poor development before they were born, or they may develop during childhood.
- Secondary cataracts. These develop as a result of other medical conditions, like diabetes, or exposure to toxic substances, certain drugs (such as corticosteroids or diuretics), ultraviolet light, or radiation.
Traumatic cataracts. These form after an injury to the eye. Symptoms and Signs: A cataract starts out small and at first has little effect on your vision. You may notice that your vision is blurred a little, like looking through a cloudy piece of glass or viewing an impressionist painting. A cataract may make light from the sun or a lamp seem too bright or glaring. Or you may notice when you drive at night that the oncoming headlights cause more glare than before. Colours may not appear as bright as they once did. The type of cataract you have will affect exactly which symptoms you experience and how soon they will occur. When a nuclear cataract first develops, it can bring about a temporary improvement in your near vision, called "second sight."Unfortunately, the improved vision is short-lived and will disappear as the cataract worsens.
Homoeopathy provides a great scope in treating cataract. After a detailed study about the patient prescription is made. It is the safer mode of treatment for cataract. Homoeopathic medicines are known to retard clouding of the lens. They are equally helpful in restoring blurred vision. Thus, homeopathic medicines helps to avoid surgery and its side effects such as infection, bleeding and retinal detachment.
