Glaucoma is a group of eye diseases characterised by damage to optic nerve usually due to excessively high intra ocular pressure (eye pressure). If left untreated can lead to optic nerve damage resulting in progressive, permanent vision loss. Glaucoma usually affects people above the age of 40, but can affect younger people as well. This condition causes fluid to build up in the eye, which puts pressure on the optic nerve. 

There are broadly two types of glaucoma - Open angle glaucoma ( more common in elderly) and angle closure glaucoma.
Women are more likely to suffer from glaucoma than men are. Ethnicity also plays an important role in determining the risk of suffering from this condition. East Asian and African Americans have a high risk of glaucoma, as they have a shallow, anterior chamber depth. Some of the other conditions that can increase a person s risk of glaucoma are:

Diabetes
Hypothyroidism
Myopia
An earlier eye surgery
Retinal detachment
Tumours
Injury to the eye
Long term corticosteroid medication
If diagnosed early enough, glaucoma can be treated and its effects can be reduced. However, the damage already caused by glaucoma cannot be reversed. The aim of glaucoma treatment is to either reduce the production of fluid in the eye or improve its flow. This helps slow down the progression of this disease and prevents any further loss of vision. Glaucoma treatment usually takes the form of eye drops or surgery.

Eye drops are the first step towards treating glaucoma. There are many different types of eye drops. Prostaglandin analogues aim at increasing the flow of fluid out of the eye and are usually prescribed in cases of swelling around the rim of the eyes, darkening of the iris and blurred vision. Beta-blockers can also help lower the secretion of fluids in the eye.

Patients who are also suffering from diabetes or lung conditions such as bronchitis may be prescribed cholinergic agents, carbonic anhydrase inhibitors or sympathomimetic drugs. Cholinergic agents help improve the outward flow of fluid in the eyes while Carbonic anhydrase inhibitors reduce fluid production in the eyes. Sympathomimetic drugs do both reduce the production of fluids and improve outflow.

If the eye drops are not effective, surgery may be advised to lower the pressure built up in the eye. Some of the common types of surgery for glaucoma are:

Trabeculoplasty: This procedure involves directing a high-energy laser beam into the eye to open clogged drainage canals. The surgery has high success rates but the problem may recur after surgery.
Filtering surgery: This involves creating an opening in the eye and removing a part of the trabecular meshwork, thus allowing fluid to flow outwards.
Drainage implants: Children or patients with secondary glaucoma may be treated with this surgery where a small silicone tube is placed in the eye to aid in fluid drainage.

Glaucoma - Factors That Put You Risk!

78% of urban youth are in front of the computer screen/ mobile screen for about 12 hours a day. Such extensive strain to the eyes can have long term effects on vision.  Act now to protect your eyes by following these tips-

1) Ensure appropriate glasses or contact lens prescription which is also adequate for computer use. 
2) For prolonged exposure, use glasses to help with contrast, glare, and eye strain when using a computer.
3) Adjust your computer such that your eyes are level with the top of the monitor. This allows you to look slightly down at the screen.
4) Avoid any glare on your computer from windows or lights. Use an anti-glare screen if required.
5) Choose a comfortable, supportive chair. Position it so that your feet are flat on the floor.
6) If your eyes feel dry, blink more often.
7) Every 20 minutes, rest your eyes by looking 20 feet away for 20 seconds. At least every 2 hours, get up and take a 15-minute break.

Protect Your Eyes While Working. 7 best ways.

High blood pressure can lead to hypertension, which is known to cause a variety of debilitating side effects or symptoms in the life of the patient. It can also lead to a number of related ailments which can affect the various organs of the body. The eyes are one of the organs that are most susceptible to this kind of spike in the body s blood pressure. Let us learn more about the connection between the two.

Retina: When high blood pressure goes untreated for a prolonged period, it can easily start to affect the blood vessels that can be found in the retina. The retina is the third or the inner most layer of the eye which is sensitive towards light and usually helps in refraction. This is where the light reaches so that one can focus clearly on an image. When the blood pressure of the patient stays high for a prolonged basis, there is significant pressure on the blood vessels in this part of the eye which can lead to an eye disease known as hypertensive retinopathy.

Symptoms: Symptoms of this eye disease include lack of clarity and focus when the eye comes to rest on an object, as well as headaches and other vision problems that typically spring from eye strain that one will go through while trying to focus even harder. It may be seen that the symptoms do not appear in the very early stages of this disease.

Diagnosis: The diagnosis of the condition is usually done by an ophthalmologist who will use an ophthalmoscope in order to project light towards the specific part of the eye so that the back of the eyeballs can be examined. The signs that the doctor will look for during the examination include narrowing of the blood vessels in this part of the eye, inflammation of the macula which is the central portion of the retina, and bleeding in the back of the eye. Also, the doctor will check for spots in the retina with the help of cotton swabs and exudates.

Treatment: The best and only way of treating this condition is by keeping one s blood pressure in control with the help of medication prescribed by the doctor.

Prevention: There are many ways of preventing the onset of this disease, including losing weight so that there is less pressure on the body. Also, one must stick to a healthy diet and exercise regularly after taking recommendations on the appropriate exercises from the doctor. Additionally, it is also important to see a doctor on a regular basis so that there is constant monitoring and regulation of the medicines and the blood pressure.

Blood Pressure - How it Affects Your Eye Sight?

7 Ways To Care For Your Eyes 

Eyes do more than we give them credit for and require more care than what we actually give them mostly. It isn't very difficult to ensure that your eyes are healthy and taken care of.

Here are 7 ways to care for your eyes everyday.

1) Splash water - Always clean your eyes with cold (filtered) water, from time to time. The clean water washes the eyes and keeps them healthy and free of diseases.
2) Don’t look into the sun - Never look into the sunlight directly. In fact, avoid looking at any sort of light that is harsh on the eyes. Direct rays of any kind of bright light can have damaging effect on the retina.
3) Get eyes examined - Have regular eye exams to check for diabetes and high blood pressure, if these health problems already exist in the family.
4) Do not smoke - People who smoke are more risk of having age-related eye problems.
5) Exercise your eyeballs - Roll the eyeballs up and down, and lift and right without moving your position. Repeat this exercise about 5 to 10 times. This helps relax the muscles in your eyes.
6) Distance eyes from screens - If you work on the computer, make sure there is enough distance between the screen and your eyes. Sit at least 22-28 inches away from the screen. The same applies while using smartphones and tablets. Do not view the screen from too close. Viewing the screen from too near as well as from too far; can increase the strain in your eyes.
7) Give them a break - People who work on the computer all day should ensure that they rest their eyes after regular intervals. Look in a long distance every few minutes.

7 Ways To Care For Your Eyes Without Making Any Effort

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.
