Vision is one of our most important senses. Reduced vision that triggers the need for corrective glasses is one of the most common disorders associated with the eyes. Crossed eyes are another such common disorder that affects the eyes. In medical terms it is also known as Strabismus. This condition is a result of miscommunication between the brain and the eye muscles that result in misalignment of the eyes. It is largely a hereditary condition and should not be confused with a lazy eye syndrome.
In fact one of the condition causing lazy eyes! Crossed eyes can cause double vision and disorientation. Your depth perception may also be affected. It also causes eye strains and headaches that affect the quality of your life. This condition is seen mostly in children. If not treated in time, it can continue into the adult years as well. The development of crossed eyes in adults who have not suffered from this condition as children is usually a sign of a serious condition such as a stroke.
Some symptoms characteristic of this condition are:
Treatment for this condition can be surgical as well as non surgical.
Non surgical treatment aims at strengthening the eye muscles and treating the visual system as a whole. The aim is to not allow the eye to become lazy or amblyopic. If the squint is due to refractive error then corrective glasses are prescribed which need to be worn regularly.
In some case lazy eye requires patching whe re it is worn over the strong eye. In some cases glasses and patching both are advised. Medication may also be injected into the eye to relax the eye in cases were paralysis is the reason for squint. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
Amblyopia is decreased vision in one or both eyes due to abnormal development of vision in infancy or childhood. It is commonly known as lazy eye, in which a child's vision does not develop properly, usually in one eye. If it is left untreated, a child's vision will never develop correctly in the affected eye.
What are the types of Amblyopia?
There are several different types and causes of Amblyopia, such as Strabismic Amblyopia, Deprivation Amblyopia and Refractive Amblyopia. The end result of all forms of Amblyopia is reduced vision in the affected eye(eyes).
How does Lazy Eye occurs?
Lazy eye occurs when your brain favors one eye, often due to poor vision in your other eye. Eventually, your brain might ignore signals from your weak or lazy eye. The condition can result in vision impairment and loss of depth perception.
What are the Symptoms of Lazy Eye?
Lazy eye may be hard to detect until it becomes severe. Early warning signs include:
What Causes Lazy Eye?
A number of conditions and factors can lead you to rely on one eye more than the other. These include:
How is Amblyopia diagnosed?
When it first occurs, parents and children often don't notice the condition. It's important to get routine eye exams as an infant and child, even if you show no outward symptoms of eye problems.
Family history of amblyopia is a risk factor for the condition.
How Is Lazy Eye Treated?
If you wish to discuss about any specific problem, you can consult an ophthalmologist.
Myopia is also known by the name of nearsightedness. It is one of the most common refractive disorders of the eye. Over the years, it has become more prevalent. According to a recent study conducted by the National Eye Institute (NEI), myopia has grown more prevalent from 25 percent in 1972 to around 40% percent in 2004 in United States.
The exact cause of the prevalence of this disorder in USA is not known. However, many doctors are of the opinion that eye fatigue due to overuse of computers can be the primary reason behind the spread of this disorder. It could also be affected by genetical links.
Myopia Symptoms And Signs:
It is time to take care of your eyes if you have difficulty in reading the sign boards on road or seeing objects from a distance. This could be a sign for myopia if you are able to see things clearly from a closer distance. There are several symptoms of myopia, including strain on eyes, headaches and squinting. If these signs don’t vanish after wearing lenses or spectacles, you must consult an ophthalmologist.
What are the factors that cause Myopia or Nearsightedness?
It occurs at a time when the eyeball of the patient is too long. The lens of the patient will be too long as compared to the focusing power of the cornea or the eye lens. This condition leads to the focusing of light rays at a point in front of the retina. The rays don’t focus directly on the retina’s surface. Myopia can also be caused if the lens of the eye is too curved. Myopia can also be caused due to a combination of factors. The problem may start from childhood. You are also at the risk of developing the problem if your parents have had the problem.
Myopia is not a rare disorder of the eye. People living with myopia have several options of its treatment. It can be rectified or corrected with the help of spectacles and contact lenses. It can also be corrected by refractive surgery. The kind of treatment to be chosen depends upon the degree of your myopia. You will be asked to wear lenses or spectacles for a prescribed amount of time, depending upon the degree of your disorder.
If you are suffering from myopia, the doctor will prescribe you to wear spectacles or lenses of a certain power that will be preceded by a minus (-) sign.
Are you planning on undertaking a cosmetic procedure for rejuvenating your skin? Botox treatment is considered to be effective for this purpose. Botox is a drug made from a certain neurotoxin, and it is produced by a bacteria known as Clostridium botulinum. Botox is also used for medical purposes, especially for the treatment of muscle related conditions. It is primarily used for removing wrinkles via a procedure in which your facial muscles are temporarily relaxed.
Except for reducing the appearance of your wrinkles and facial lines, which appear because of aging, botox is used for the treatment of conditions which include leaky bladders, migraines, excessive sweating, and eye squints. Over 20 medical conditions utilize botox as a part of treatment.
How it works?
Botulinum toxin or botox is a poisonous substance. A single gram of botox can kill over one million people. But it acts as an ideal therapeutic protein when utilized in a proper, required dosage.
About botox procedure
Botulinum toxin powder is diluted in saline to be administered. It is injected into a patient’s neuromuscular tissue and takes around 72 hours to show results. This time reflects the amount of time that is required for disruption of your body’s usual synaptosomal process. It takes around 5 days for the full effect of botox treatment to show. Pregnant or lactating women, and people who are allergic to it from a previous treatment should avoid any form of botox treatment.
Side effects and associated risks
Although injections containing botox are well tolerated, there are several side effects involved. They are as follows:
The results obtained from treatment by type B botox is said to be more effective than botox A treatment. You may expect better results when your muscles remain contracted instead of being relaxed. If you wish to discuss about any specific problem, you can consult a dermatologist and ask a free question.
Are you planning on undertaking a botox treatment? Botox is a drug which is made from a neurotoxin. This is produced by the bacteria called Clostridium botulinum. Botox is used for medical purposes, commonly for treating muscular conditions. It is also used for cosmetic procedures, which help in removing wrinkles. This process is carried out by paralyzing the facial muscles temporarily. Botulinum toxin is also sold commercially under certain names.
Medical and Cosmetic Uses-
Botox is most commonly used as a treatment procedure for reducing the appearance of facial lines and wrinkles in middle-aged adults. It is also used for medical purposes, for the treatment of conditions such as eye squints, excessive sweating, leaky bladders and migraines. Botox is used for treating more than 20 medical conditions.
How Does Botox Work?
Botox or botulinum toxin is a very poisonous substance, and a single gram of it is capable of killing more than one million people. It is considered to be an effective therapeutic protein when used in ideal dosage, and frequency. It is used in several medical procedures and treatment therapies.
How is Botox Procedure Undertaken?
Botulinum toxin is administered by diluting the power in saline. It is injected directly into your neuro-muscular tissue. A duration of 24 to 72 hours is required for it to take effect. This time reflects the time required for disruption of the normal synaptosomal process of the body. It may take over five days for experiencing the full effects of botox. Botox must not be used in women who are pregnant or lactating, or by people having a previous allergic reaction to it.
Risk and Side-Effects:
Injections which contain botox are usually well tolerated. They have several side effects as well.
In some cases, a person may have a genetic predisposition which causes a mild, transient and unusual response to Botox. Some people who are receiving botox type A injections may develop antibodies to the toxins, which may make the treatment ineffective. In people who are using botox type B for cervical dystonia, antibody development may occur.
Along with the effects intended, botulinum toxin may lead to several other undesirable effects. They may include conditions such as transient numbness, headaches, malaise, mild cases of nausea, mild pain, local edema and erythema on the site of injection.
Drooping or temporary upper lid and brow ptosis are also indicated.
Among the two types of botox treatments, the results from abobotulinum toxin A is considered to be more effective than onabotulinum toxin A treatment. Better results are experienced when the muscles are contracted instead of being at rest. If you wish to discuss about any specific problem, you can consult a dermatologist and ask a free question.
Normally the eyes are the best friends. They blink together. They move together and always keep the visual axis parallel, how paradoxical it is that healthy eyes visual axis never meet but it is the eyes who make you meet the desired person in your life.
When visual axis is not parallel in any direction of gaze, we call it a squint
Squint can be congenital or acquired. Congenital squints are usually more difficult to treat. Acquired squint may be due to refractive error. They can be traumatic causing paralytic squint which is more difficult to treat.
If both eyes converge (turn inside), we call it convergent squint. If they diverge, we call it divergent squint.
The squint can be constant or inconstant (sometimes).
A squint patient has to be examined fully by a very competent ophthalmologist at the earliest opportunity. The doctor shall find out the type of squint, its degree, and its nature. Fundus has to be examined. Refraction has to be done. Convergent squint patients quite often have a hypermetropic refractive error and sometimes can be cured by spectacles and exercise. Myopic eyes most often have a divergent squint. In some patients, the squint is quite hidden (latent) and it appears occasionally when patient have a strong emotion or absent minded. Most often these squints are divergent.
The challenge in surgery shall depend on a degree of squint, an age of onset, type, and age of surgery. Ideal age of squint surgery is 5-10 years. More the age, unpredictable results. Simply drugs do not cure squint. Paralytic squint more challenging. Earliest the better
