Glaucoma is a leading cause of blindness in people across the globe. It damages the optic nerve that carries sensory images from the retina to the brain. A faulty eye pressure is responsible for damaging the very delicate optic nerve fiber causing small blind spots in the retina. Unfortunately, for most patients this disease only gets diagnosed when the number of blind spots is on the higher side.
Types of Glaucoma
- Open angle: This is a type of Glaucoma which results from the blockage of the drainage angle of the eye resulting into an increased eye pressure.
- Angle closure: This is the kind of Glaucoma which results from the narrowing down of the drainage angle leading to complete blockage.
Target segment of Glaucoma
- Family history: Inheritance surely plays a role in case of Glaucoma too. If Glaucoma runs through families of an individual, there are higher chances of getting this disease. Although there is no hard and fast rule about it, the risks of inheriting this disease are on the higher side.
- Eye injury: If there is any history of previous eye injuries, the probability of the onset of Glaucoma cannot be turned down. Specially, if the injury is related to optic nerve, there are very high risks involved.
- Bilateral Oophorectomy: Dual Ovary removal before the age of 40 results in deficiency of estrogen resulting in Glaucoma. Although most surgeons warn their patients of the possible risk of these procedures, many surgeries such as these have resulted in patients losing eyesight in the form of Glaucoma.
- Patient with Diabetes: In case of acute diabetes, retina gets damaged and the eye starts producing new blood vessels on the iris resulting into an increased eye pressure. This condition often leads to Glaucoma due to blockage of fluid flow in the eye.
- Eye Conditions: Myopia, multiple surgeries to the eye, blunt trauma etc. can lead to Glaucoma. A patient who has undergone any kind of eye surgeries suffers from inflammation. However, major inflammation is often found twisting blood flow in the eye resulting into Glaucoma.
- If a patient is 40 or above: After a person reaches 40 years of age, a lot of diseases start cropping in to the body. Studies show that Glaucoma has a higher frequency in people who is more than the age of 40 or above.
- High eye pressure: A patient with an eye pressure of above 21 mm HG is also at a very high risk of getting glaucoma. For a normal person the IOP lies between 10 to 21 mm HG.
- Blood flow related disease: Diseases such as acute migraine, hypertension and low blood pressure which involves blood flow related problem often aggravate to glaucoma.
- Ethnic Background: Statistics show that people from Afro American, Hispanics, Asian and Caribbean background have greater chances of being affected by Glaucoma.

Ebooks maybe are a lot easier to carry, and with the emerging trend of Kindles, it may appear to be more convenient than paperbacks, but the smell of new books, the texture of its pristine pages, is unparalleled to the inanimateness of ebooks. But that is not just why you must choose paperbacks over ebooks.
Read on to find out why paperbacks work well over ebooks for better eye health:
- Does not involve light-emission: The backlit electronic devices, strain your eyes, causing redness, irritation and watering. Most doctors advise that exposure to light during the evening, especially from artificial sources should be minimal. On the other hand, books do not emit any harmful rays, making it the obvious choice if you want to take good care of your eyes.
- Do not hamper body clock: Our system has a tendency to adapt itself to the rhythm of life by responding to the surrounding light. However, the blue light in reading devices disrupt the release of melatonin or the sleep hormone, causing inadequate, less deep sleep, and fatigue and irritation the following morning. Thus, not giving enough time to your eyes and body for revitalizing. On the other hand, studies have shown that people reading books sleep better and timelier than those reading on devices.
- Proximity to device not required: The admonition of not sitting too close to the television's screen glare is nullified by reading devices where a certain level of proximity is required for comfortable reading, which harms our eyes. But paperbacks do not have any such risk involved as there is no glare that would affect our eyes.
- Does not induce disrupted winking: Electronic devices often trigger a tendency to not blink and stare at the screen constantly for longer than advisable. That does not give the lenses in your eyes the momentary rest that the eyes require in order to replenish themselves.
Exercises to improve eye health:
There are many common measures people take to improve their eyesight or improve their vision. These include wearing glasses, lenses, sunglasses and many such measures. Here are some effective exercises which prove to be highly beneficial in increasing your eye health:
- Stretching: This is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds, then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.
- Flexing: This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.
- Focus switching: This particular eye exercise is used for accommodation and is probably the most useful one. In this eye exercise, you have to hold something at a reading distance and cover the other eye. You then have to find something that is at least twenty feet away and trace its shape with one eye closed. With one eye closed, trace more shapes which are twenty feet away and this may improve your eyesight.
- Palming: This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to destress the eyes.
- Deep blinking: This is also an incredibly useful exercise for distance vision. All you have to do is to place some large letters at a fair distance and then sit on a chair. You have to then close your eyes and tighten all your muscles for 5 seconds. After the gap of 5 seconds, open your eyes and see the letters for a second or two. The more time you do this the more clearly you will be able to see the letters after reopening your eyes.
Finally, a warning has to be given that these eye treatments are not universally accepted by all doctors.

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 headache 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. If you wish to discuss about any specific problem, you can consult a Ophthalmologist.
