Astigmatism is a typical vision problem that occurs when the shape of the cornea is distorted due to injuries or other causes. With astigmatism, the lenses of the eye or the cornea curves. This irregular curve can change the way light refracts or passes through your retina. This causes hazy, fluffy, or twisted vision. Farsightedness and partial blindness are two different sorts of issues with the way light goes to your retina. Farsightedness is called hyperopia. Partial blindness is called astigmatism.

Types: There are two types of Astigmatisms. These are:

1. Corneal astigmatism
It happens when your cornea itself is distorted.

2. Lenticular astigmatism
Lenticular astigmatism happens when your lens is distorted.

Risks: Astigmatism can happen in youngsters and grown-ups. Your danger of creating astigmatism might be higher if you have any of the following:

1. A family history of astigmatism or other eye issues like dislocation of the cornea.
2. Scarring or diminishing of your cornea
3. Excessive partial blindness, which makes foggy vision at a separation
4. Excessive farsightedness, which makes hazy close-up vision
5. A past of eye surgeries, for example, cataract surgery (surgical expulsion of a blurred focal point)

Symptoms; The side effects of astigmatism include:

1. Hazy, Bended, Or Fluffy Vision At All Separations (Close-Up And Far Away)
2. Trouble seeing during evening
3. Lazy eye
4. Squinting
5. Irritation in the eye
6. Cerebral Pains

Diagnosis:

Visual Acuity Assessment Test

Patients are required to read letters from a graph at a particular distance to decide how well they can see the letters.

Refraction Test

A refraction test uses a machine called an optical refractor. The machine has various remedial glass lenses that are used to read an outline while looking through lenses on the optical refractor.

Treatment:

Keratometry

Keratometry is a route for your specialist to measure the bend of your cornea. They will do this by taking a look at your eye through a keratometer.


Corrective Lenses

Remedial eyeglasses and contact lenses prescribed by a specialist are the most well-known and least obtrusive solution for astigmatism.


Orthokeratology

Orthokeratology is a treatment that uses contact lenses to correct the deformation and flow of your cornea. You will wear inflexible contact lenses for certain time-periods. It is easier to wear them while you are sleeping and remove them during the day.


Surgery

Your specialist may suggest refractive surgery if your case is a serious one. This kind of surgery includes use of lasers or little blades to reshape your cornea. This will correct astigmatism permanently. The three basic surgeries for astigmatism are:

1. Laser in situ keratomileusis (LASIK)
2. Photorefractive keratectomy (PRK)
3. Spiral keratotomy (RK).

All these surgeries might carry some risks depending upon the symptoms of your problem. As innovation advances, it is very important for the patient to explore more options before choosing which refractive surgery is a good fit for him or her.

Types and Treatment for Astigmatism

A person is said to have great vision more in the metaphorical way than in the literal sense. However, having both is just so important, especially as the ability to see reduces as a person gets older. Old age comes with its own set of problems, and vision loss is one of them. If kept in check from an early age, however, vision loss can be deferred indefinitely.

While a person's eyesight is likely to deteriorate over the course of his life, there is a lot which can be done in an effort to make sure that this is not the case. To start with, it makes good sense to be regular with eye check-ups. After a person attains the age of sixty, he or she should have a doctor take a look at his or her eyes on a yearly basis. There is no point trying to conserve eye sight if a person is too late in taking corrective action. By paying a visit to the ophthalmologist, a person will get to know the exact problem that he is suffering from.

A good diet which is rich in the nutrients which improve a person's eye sight does go a very long way in the long run. A person should make sure that is diverse enough to take care of the needs of a person and should include grapefruit, strawberries as well as berries and nuts.

One of the main things which can be done in order to preserve the health of a person's eyes until he or she reaches an advanced age is to stop smoking in all forms. As a matter of fact, tobacco leads to cyanide entering the blood stream and this does a lot of damage to the eyes. In fact, quite a few irreversible conditions of the eye are caused due to this.

Exercise is said to be good for a person at any age for a variety of reasons and it is really good for even the eyes, though the link may not be immediately so clear. It reduces the risk of age related degeneration by up to 70 per cent!

What is really interesting about a person's eyes is that they can be signs of trouble in other parts of the body. For example, if a person has blurry vision, they should get checked for diabetes. Also, eyes which do not produce enough natural lubrication can show a risk of rheumatoid arthritis and perhaps even thyroid disease.

All in all, a person's eyesight is so crucial to his or her overall health and wellbeing. We have only one pair of eyes, so we might as well take care of them!

Tips to Prevent Vision Loss in Elderly People

Hypertension is a killer disease whose symptoms develop late when the damage is in advanced stages. Hypertensive Retinopathy is one such disease.

It damages the retina of eyes. Since retina is responsible for vision formation, Hypertensive Retinopathy can result in loss of vision. It is of grave concern that in most cases, Hypertensive Retinopathy is diagnosed later.

This is due to the fact that there are often no symptoms in the early stages of the disease. In some cases, where symptoms do manifest, patients may experience pain in the eyes, reduced vision, or headache.

What Happens in Hypertensive Retinopathy

People suffering from long term hypertension are susceptible to Hypertensive Retinopathy. Long-term hypertension affects the small and narrow blood vessels that join arteries to capillary blood vessels taking blood to different parts of the eye. These blood vessels become narrow with time if hypertension in the eyes continues unabated. This narrowing is more common in young adults compared to older people. Such unabated systemic hypertension also leads to leakage of fluid. This is why in some cases of Hypertensive Retinopathy, patients may experience exudation. Ultimately, Hypertensive Retinopathy may lead to damage to retinal blood vessels.

Risk Factors

Long standing hypertension is the number one risk factor for Hypertensive Retinopathy. People who are suffering from longer hypertension become most susceptible for this ailment.

However, studies have shown that hypertension for more than 5 years can even make people susceptible to this ailment.

Diagnosis

Diagnosis is done by Funduscopic Examination. The doctor would look at the eyes of the patient through an Ophthalmoscope which has different lenses. The Ophthalmoscope illuminates the retina and the doctor looks at the retina with different lenses. He can get a view of the retina, including blood vessels and optic nerve disks.

Findings of Diagnosis

For a person suffering from Hypertensive Retinopathy, this examination is likely to show:

Constriction of the arterioles.

Changes in the walls of retinal blood vessels.

Flame-shaped hemorrhages in the retina.

Yellow and hard exudates.

Spots in the shape of cotton wool.

Swelling of the optic disc.

Treatment

The primary treatment for Hypertensive Retinopathy is controlling blood pressure of the eyes. Some lifestyle changes like reducing the intake of salt, avoiding tobacco, etc., may bring down or control systemic hypertension in the eyes. In many cases, doctors may just recommend lifestyle modifications. Nevertheless, it completely depends on the extent of the damage and whether or not there is any fluid accumulation.

If the doctor feels that lifestyle modification is not enough, he may go for medicines that help the patients to control blood pressure effectively.

If the problem is in advanced stages and there is fluid accumulation behind the retina, the doctor may go for Intravitreal injection or Laser Therapy to control the edema.

Conclusion

Eyes are one of the most significant part of the body, this is why it is important for people to take care of it. In case of disease like Hypertensive Retinopathy, one must consult a doctor before opting any treatment or medicines.

Hypertensive Retinopathy - Everything About It!

If you have got diabetes, then it is quite natural that you will soon face acute eye troubles. This is the reason diabetic patients are always suggested to keep their blood sugar levels controlled so that eye troubles can be easily avoided. Thorough medical check-up is required in order to detect conditions of the eyes. Some of the commonest eye troubles occurring due to diabetes are cataract, glaucoma, blurry vision, diabetic retinopathy and others. 

List of eye diseases caused by diabetes

1. Diabetic retinopathy: when the retina's smallest blood vessels get severely damaged due to increased blood sugar, then this kind of eye condition occurs. Early detection of this eye condition can save your eyes, but if it is too late, then nothing can be done, and it might even lead to blindness.

2. Cataract: fogging or clouding condition can bring this kind of condition and this can only be corrected by wearing proper corrective lenses. However, if you fail to control diabetes, then in spite of wearing glasses, your eye condition might get deteriorated day-by-day. Glared or blurred vision is the most common symptom in this regard. 

3. Glaucoma: when the eye fluid is not drained properly, then this kind of eye trouble occurs. In fact, eye pressure increases to a great extent as a result of which delicate eye nerves can get severely damaged. The blood vessels of the eyes can get clogged causing greater interruption in vision. Medicines can make aqueous humor to get drained in a proper manner, and thus you should go for a proper eye check-up so that you can acquire the requisite medicines. Some popular symptoms of glaucoma are headaches, eye aches, blurred vision, watery eyes, vision loss and others. 

4. Diabetic macular edema: this eye disease mainly occurs in the advanced stage of diabetic retinopathy. Macula is nothing, but the most delicate part of retina and when it gets swollen, then you might face this eye trouble. Only medications can help you to get rid of the same and thus immediate medical help is needed. 

5. Blurry vision: though this is quite a small and temporary eye issue for diabetic patients, but this condition might turn into a serious one if you neglect to correct the same in the very beginning. You might even face blindness due to negligence of this trouble. Also, fluctuating sugar-levels should be stabilized so that this kind of trouble can be easily tackled.

Eye Problems Caused by Diabetes

Macular Degeneration is a condition in which the central part of the retina degenerates. In this condition, the posterior part of the eye, retina, is affected.

The central part of retina, macula, is associated with the central vision in the eye. The macula is responsible for controlling various abilities, such as distance perception, perceiving faces and colours, and identifying fine details of the objects. When this central part degenerates, the person slowly loses the ability to see clearly.

Such a condition can be treated with ayurvedic remedies.

Cause

The main cause of macular degeneration is the damage to the macula, the central part of the retina. This reduces the person s ability to have a clear vision. This condition progresses with time and can result in complete blindness.

Type of Macular Degeneration

Macular degeneration is of two types:

Dry Macular Degeneration: In this condition, there is a change in the pigment of the macula. Moreover, small piles of waste products generated by cells also appear on the retina. These tiny waste piles deteriorate the retina over time. Among people affected by macular degeneration, almost 90 percent of people have  dry  macular degeneration. This condition is also called non-neovascular AMD (age-related macular degeneration)

Wet Macular Degeneration: In this condition, new blood vessels begin to grow behind the retina in the choroid layer. That is why this condition is also referred to as Choroidal neovascularization (CNV). These new blood vessels are weak and begin to leak fluids, blood, and lipids (parts of cell structure). These leaks get into the layers of the retina and macula that results in scar tissue. Since wet macular degeneration is caused by leaking of fluids from newly formed blood vessels, it is also called neovascular AMD.  

Treating Macular Degeneration with Ayurveda

In Ayurveda, there are several types of herbal medications that ensure improving the vision quality and enhancing the overall quality of life of the patient.

Some of the eye supplements for macular degeneration is Ayurveda are:

Triphala Guggulu: One of the most effective herbs in Ayurveda, it has an antioxidant effect that protects the eye against free radicals and treating macular degeneration.

Shilajeet (Asphaltum): This herb is associated with anti-aging properties. It restricts the degenerative process in the eye that result due to the advancing age.

Ashwagandha (Withania somnifera): For managing macular degeneration in India, this herb is used to regenerate macula and helps in restoring the vision.

Giloy (Tinospora cordifolia): This herb protects the eyes from free radicals and prevents blindness due to macular degeneration.

Amalaki (Phyllanthus emblica): It is a source of vitamin C that prevents the deterioration of the retina and macula.

Take Away

Macular degeneration is caused due to the deterioration of the central part of the retina. It is caused either in the  dry  form or  wet  form. Dry AMD is common in people. Ayurveda can help in regenerating and restoring the functioning of retina and help is improving overall vision.

10 surprising facts about your eyes

You never tend to pay a lot of attention to your eyes unless they are affected by some serious disorder or unless your vision is disrupted. But did you know that your eyes are capable of doing much more than you can imagine? here are 10 surprising facts about your eyes you didn't know about.

1. How intricate!

Your eyes take more than 2 million working parts to function. No wonder your eyes are the second most complex organ of your body after your brain.

2. A lot depends on them

As much as 80% of your memories are determined by what you see. Also, 80% of what you learn is because of your eyes.

3. Retina and security

The iris of your eyes has approximately 256 unique characteristics, which is more than even your fingerprints. This is the reason why retina scans are used so widely today for security purposes.

4. It's a colourful world

Your eyes can distinguish between approximately 10 million different colours. And women with a particular kind of genetic mutation can see millions of more colours.

5. Upside-down

The retina of your eyes receives the vision of the outside world as upside down. It is your brain, which flips the image for you so that you can see the world as it is.

6. Sunscreen for the eyes?

It is possible for your eyes to get sunburnt. Therefore, it is advisable for you to wear sunglasses in order to protect your eyes from the ultraviolet radiations.

7. Godspeed!

The eye muscle is the muscle that reacts at the fastest rate out of all the other muscles in your body. It can contract in less than even 1/100th of a second.

8. Paint it red?

The retina of your eyes cannot detect the red colour. The retinas do have green, red and blue receptors, but the red receptor can detect only the colour yellow-green and the green one can recognise blue-green. It is your brain that combines these signals to give you the impression of the colour red.

9. Dreams and sight

Even if you become blind later in life, you can see images in your dreams if you were born with sight.
