Diabetic Retinopathy - Causes, Symptoms And Treatment!

If the people suffering from diabetes find their vision clouded or distorted, then the condition is called Diabetic Retinopathy. The vision gradually grows weaker till there is a complete loss of vision.

Causes Behind the Condition-

1. If the sugar content in blood is high, then it might lead to clogging of the small blood vessels that supply blood to the retina. The eye tries to compensate for the narrowing blood vessels by growing new blood vessels. These are in some cases weaker, liable to leak and can to serious complications.

2. In some cases, the newly grown blood vessels are not weak, but they interfere with the stable flow of liquid. This puts undue pressure on the eyeball. In such cases, the optic nerves are damaged, causing glaucoma.

Symptoms of Diabetic Retinopathy-

1. Symptoms are usually developed in the later stages of the diabetic retinopathy. Sometimes clouding of the vision indicates this.

2. Eye floaters are common symptoms for Diabetic Retinopathy. These are strips of protein and blood cells that float before the lens obstructing clear vision.

3. If your normal color vision begins to fluctuate from time to time, Diabetic Retinopathy is a likely explanation.

4. A gradual loss of vision is experienced leading to complete blindness in severe cases.

Treatments for Diabetic Retinopathy-

The treatment procedures for diabetic retinopathy are usually surgical:

1. Vitrectomy:

A tiny incision is made in the eye to remove the blood accumulating in the middle of the eye along with the scar tissue that the retina has on it.

2. Treating with Focal Laser:

Laser burns are used to treat the faulty blood vessels that are leaking.

3. Treating with Scatter Laser:

This treatment uses laser burns to shrink the malfunctioning or leaking blood vessels or the scar tissue that clouds vision by accumulating on the retina.

Diabetic Retinopathy - What Is It Exactly?

Diabetic retinopathy is an eye problem that affects the retina of the eye and causes total and irreparable blindness. It usually occurs after 15 to 20 years of diabetes. Poorer the control earlier is the onset. Association of hypertension and increased blood cholesterol make the condition more serious.

In initial stages, there may not be any visual symptoms. Some patients may get macular edema marked with a decrease in the vision without exhibiting diabetic retinopathy.

Here is some important aspect of the disease that you should know:

Symptoms as the condition progress: you might experience blurred or fluctuating vision, impaired color vision, spots or dark strings floating in your vision, dark or empty areas in your vision and an even significant decrease in vision which is not corrected with glasses. Diabetes can cause early cataract formation (diabetic cataract) in the eye.

Causes: In an uncontrolled diabetic patient, the blood supply to the retina is decreased due to vascular constriction, in due course of time. This causes anoxia which promotes new vessel formation which may leak causing macular edema and or exudates. The newly formed vessels are fragile, can cause small projections (aneurysms) or may bleed. This all happens in the most sensitive central part of the retina (macula) thereby affecting vision to varying degree.

Advanced diabetic retinopathy: more edema, exudates, and hemorrhages occur. The newly formed vessels may profusely bleed in the cavity of the eye, seriously affecting vision. In due course of time, retinal fibrosis occurs which may cause retinal detachment and total blindness. Few eyes may develop an increase in intraocular pressure (glaucoma) at any stage of the disease, causing blindness even without advanced diabetic retinopathy.

When does the risk increase: longer the duration, higher the incidence. If you have an uncontrolled blood sugar ideally evaluated by hb1ac (glycosylated HB) test, hypertension and increased cholesterol. Pregnancy too increases the risk. Ethnicity plays an important role. More prevalent in native Americans, Hispanics and Africans and now some studies highlight incidence in southeast Asia, including Indians.

When should you consult ophthalmologist: once you are declared diabetic, you must consult an ophthalmologist. Thereafter as per his advice every one or two years or even early if your control is poor or if your parents suffered from advanced diabetic retinopathy. If you are pregnant, eye examination may be needed frequently. Remember, proper control of risk factors and timely examination and intervention can prevent you from becoming blind. A Recent introduction of oct evaluation & intravitreal therapy has significantly helped patients with diabetic retinopathy. In case you have a concern or query you can always consult an expert & get answers to your questions!

Diabetic & Hypertensive Eyes - How to Take Care Of Them?

You know that diabetes is a chronic condition that renders difficulties to the patient in several aspects. A comprehensive care is essential to manage it effectively as the condition can lead to many other diseases including eye diseases.

If you have been diagnosed with diabetic or hypertensive eyes, then it means that your vision has started to deteriorate. But you need not lose hope as it is still possible to remedy the situation. Understanding the issue in detail will help you cope with the situation better.

What are diabetic and hypertensive eyes?
Diabetic eye refers to the complications in the eyes as a result of diabetes. It affects the blood vessels of the retina and hence develop impairment of vision and loss of vision in severe cases. Similarly, hypertensive eye as indicated by the name is the situation where in the eye is affected as a result of hypertension. This is because high blood pressure affects the blood vessels of the retina. It does not allow the retina to function properly and puts pressure on the optic nerve resulting is vision problems.

What are the symptoms of diabetic retinopathy?

Like many conditions of this nature, the early stages of diabetic retinopathy may occur without symptoms and without pain. An actual influence on the vision will not occur until the disease advances. Symptoms may only become noticeable once the disease advances, but the typical symptoms of retinopathy to look out for include:

  1. Sudden changes in vision / blurred vision
  2. Eye floaters and spots
  3. Double vision
  4. Eye pain

How to take care of the conditions?
In the conditions of the diabetic eye and hypertensive eye that prime step to take care is to control diabetes and hypertension respectively. By following the prescribed medications for these conditions, the vision problem can be managed. At the same time, some adequate preventive measures are of utmost importance to efficiently and effectively take care of both diabetic eye and hypertensive eye.

Taking care of diabetic eye
First and foremost, you need to keep your diabetes under control and prevent it from being getting into the advanced stage. You should take utmost care to maintain the blood sugar level under control. After that, it is also necessary to keep the blood pressure in the correct range. Also, the cholesterol level in the blood needs to be under control. A proper and balanced diet is essential in this case. Whole grains, green leafy vegetables, fruits and lean protein should be included in the diet. Exercising is also very important to deal with diabetic, and if you are a smoker, you should quit it immediately since it causes problems with the blood vessels.

Taking care of hypertensive eye
You should bring down your blood pressure to the correct level and maintain it. You should consume a diet which contains all the essential nutrients, vitamins, and minerals. You should make sure not to do or involve in anything activity that can increase your tension or excite you. Smoking and drinking should be avoided to deal with the hypertensive eyes effectively. You should get yourself adequate and peaceful sleep which will help you to ease out of tension.

It is imperative to consult an ophthalmologist if you notice the classic symptoms of vision problems such as blurry vision, seeing floaters or flashes. If the condition progresses, treatment will involve medications or surgery depending on the severity of the condition. Hence, the best way to avoid such complications is to maintain a healthy lifestyle to take due care of your eyes.

Diabetic Retinopathy - Important Facts You Must Know About!

Diabetic Retinopathy - Important Facts You Must Know About!

Diabetes is a scourge that has been spreading like wildfire across the globe. It is one of the major public health concerns of the modern era. Diabetes not only causes damage to your internal organs but will also take a toll on your eyes if left unchecked. Retinopathy, glaucoma, cataracts and blurry vision are common phenomena accompanying diabetes. 

You may not notice it at first. Symptoms can include:

  1. Blurry or double vision

  2. Rings, flashing lights, or blank spots

  3. Dark or floating spots

  4. Pain or pressure in one or both of your eyes

  5. Trouble seeing things out of the corners of your eyes

Thus Comprehensive Dilated Eye Exam plays an important role to detect it.

Here are some common Diabetic Eye Problems:

  1. Blurry Vision: Do things turn blurry for you at times? Well it is not your glasses which are at fault but your high blood sugar count swelling up the lens within your eye and changing your ability to see. In order to correct your vision, you need to try bringing your sugar level back to the optimal range, which is 70 to 130 milligrams per deciliter. Do call on a doctor if the situation persists or deteriorates further.

  2. Cataracts: Your eye lens is just like a camera that enables you to see through it by focusing on a particular object. If you have cataract, your otherwise clear lens gets shrouded a layer making it opaque and cloudy. You tend to face difficulties in the form of glares, blurred or clouded vision, and blind spots among other problems. Diabetics are prone to acquiring cataract much earlier than others, with the condition worsening subsequently. They are removed via surgery where your doctor substitutes your hazy lens with a new artificial one.

  3. Glaucoma: You eye transmits images to your brain through the optic nerve. Pressure may build up within the optic nerve resulting in damage and ultimately causing total or partial blindness. This is a fairly common disorder with diabetics and a large number of cases pertaining to blindness due to diabetes are caused by this. Usually, glaucoma can be treated with laser, surgery, eye drops or medicines.  It is important to visit a doctor as it can help stop the progression of the disorder much earlier.

  4. Diabetic Retinopathy: The retina is a cluster of cells behind your eyes that absorbs light and converts them into images that are sent to the brain via your optic nerve. High blood sugar count can actually wreak havoc on the tiny blood vessels within your retina giving rise to diabetic retinopathy. Symptoms may include blurry vision, seeing spots, blind spots and difficulty in low light or night time. Retinopathy can cause you to progressively go blind and thus it is imperative that you go for periodic check-ups and keep your diabetes under control.

Control and Prevention

If you have diabetes, you are not doomed to develop diabetic eye disease. Although you are at risk, you have the ability to control your diabetes so your vision is not compromised. Controlling diabetes requires you to monitor your blood sugar levels regularly. Follow some steps to help you control and preserve your vision:

  1. Taking your Medicines regularly as prescribed by your doctor. Skipping of medication may leads to irregular control and is more hazardous.

  2. Eating Right food is essential when trying to prevent or control diabetes. Eat a diet that is high in nutrients, low in fat and moderate in calories. A high-fiber diet with low glycaemic index foods (slow-release carbohydrates) will keep blood sugar steady and make you feel full. Although you do not need to eliminate sugar completely, you must limit sugar to a small serving. The good news is that as you cut sweets, your cravings will change and you will naturally desire more healthy foods.

  3. Keep your A1C level under 7%: A1C is a test you have during a visit to your endocrinologist to determine how well-controlled your diabetes has been during the previous 2-3 months. Keeping your blood glucose in this target range means less damage to the delicate blood vessels around your eyes.

  4. Control blood pressure and Cholesterol Levels: People with diabetes have a greater chance of having high blood pressure and Cholesterol, which can cause eye blood vessel damage.

  5. Regular Physical Exercise can help you control your blood sugar, increase fitness and reduce your risk for heart disease and nerve damage. You must track your blood sugar before, during and after exercise to prevent hypoglycaemia.

  6. Annual comprehensive eye exams: If you are pre-diabetic or diabetic, it is even more important to have Complete Dilated eye exam to initially get baseline recordings of the eye conditions and then regular yearly follow-up visits to monitor changes in your vision. If you notice blurred vision and you have had diabetes for a length of time, it might be a signal you need to keep tighter control of your glucose levels.

Diabulimia - Should You Be Worried About It?

Diabulimia - Should You Be Worried About It?

Diabulimia is an eating disorder often associated with Type-1 Diabetes. Also referred to as ED-DMT1, not many people are aware of this non-clinical term. It is a well known fact that many people with Type-1 diabetes require the daily administration of insulin. In the case of Diabulimia, a person having Type-1 diabetes purposely manipulates with the insulin dosage in an endeavour to lose weight. In some extreme cases, a person may completely avoid the use of insulin.

You need no rocket science to understand the impact diabulimia will have on a diabetic patient (Type-1) who is entirely dependent on insulin. Some of the lethal consequences of diabulimia include

  1. Yeast infections: Manipulating with the appropriate dosage of insulin can trigger an abnormal rise in the blood glucose level (Hyperglycemia), some of which gets eliminated out through the urine, thereby enabling a person to lose weight. However, the high glucose level is just the ideal and favorable condition for yeast growth. The hyperglycemic condition will result in increased yeast infections. The infection can be very uncomfortable and annoying. In fact, there will be repeated yeast infections until the blood glucose level comes down to the normal range.
  2. Ketoacidosis: As already mentioned, diabulimia devoids the body of insulin. As a result, glucose is unable to enter the body cells (glucose is an important fuel for the muscles and the other cells and tissues of the body). In its absence, the body starts looking for alternate sources. Gradually the body starts breaking down fats to get the desired energy. Increased breakdown of fats results in accumulation of ketone bodies in the bloodstream, a condition medically termed as Ketoacidosis or Diabetic Ketoacidosis. The condition if left untreated can be harmful triggering Cerebral Edema (a condition characterized by a swelling of the brain), Hypokalemia (low potassium level) or even Hypoglycemia.
  3. Diabetic retinopathy: Hyperglycemia can spell doom for your eyes. The accumulation and buildup of high levels of glucose in the eyes often damage the retinal blood vessels, a condition known as Diabetic Retinopathy. There may not be any early signs associated with the condition. However, diabetic retinopathy can give rise to many serious complications such as Glaucoma (characterized by severe damage to the optic nerve), Vitreous Hemorrhage (the blood leaks into the areas adjacent to the vitreous humor of the eye), or even Blindness. There may also be a Retinal Detachment.
  4. Renal failure: One of the common and harmful consequences of diabulimia is the kidney failure. Increased concentration of glucose in the kidneys often damages the filtration units of the kidneys called the Glomeruli (increased glucose blocks the capillaries of the kidney) leading to kidney damage and failure.

Diabetic Retinopathy - What you should know?

Diabetic Retinopathy is a complication of the eye that occurs because of diabetes. It is a condition that damages the light-sensitive tissue of the retina. It can start with a medium to low level of problems in vision and can advance to complete blindness. It is mostly witnessed in patients who are suffering from type 1 or type 2 diabetes. An uncontrolled blood sugar and diabetes levels in a patient pose a greater threat of diabetic retinopathy.

What are the symptoms?
Diabetic retinopathy could be devoid of any symptoms in its early stages. However, as the condition progresses, a person might experience the following symptoms:

  • Empty or dark areas in the vision
  • Blurred vision
  • Spots floating in the vision
  • Fluctuating vision
  • Complete loss of color vision
  • Complete vision loss

Possible causes of Diabetic Retinopathy
Too much sugar in the blood vessels can block the blood supply in the retina. In the meanwhile, new blood vessels can form in the eye that does not fully matures and leak easily. Typically, there are two types of diabetic retinopathy:

  1. Early diabetic retinopathy: This is the type of diabetic retinopathy where the new blood vessels haven’t started growing in the eye yet. This condition is also known as NPDR. In this phase, the walls of the retina blood vessels weaken and numerous tiny bulges extend from the vessel walls. This condition could even leak blood into the retina. The nerve fibers and the macula tend to swell and requires immediate treatment.
  2. Advanced diabetic retinopathy: This is the most severe and advanced type of diabetic retinopathy and is known as proliferative diabetic retinopathy. This is a condition where the damaged blood cells shut down resulting in the growth of new and abnormal blood vessels. It leaks a jelly like substance and fills the vitreous. Eventually, the scar tissue can detach the eye from the retina. It can also result in a condition known as glaucoma.

What are the risk factors involved?
Patients suffering from diabetes can have diabetic retinopathy. The risk factors further increase in the following condition persists:

Tests and diagnosis:
An ophthalmologist tests the vision, look for cataracts and measure the eye pressure. In addition to this, he looks out for symptoms of abnormal blood vessels, retinal detachment, the growth of scar tissue swelling of the retina etc. A doctor might also prescribe tests such as optical coherence tomography and fluorescein angiography.

Treatment:
For early diabetic retinopathy, a doctor might not take any action but closely monitor the condition. If it aggravates, a doctor starts treatment when he deems fit. For advanced diabetic retinopathy, the doctor might go for focal laser treatment, scatter laser treatment and vitrectomy. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.

Annual Eye Exam - 3 Reasons Why It Is Important!

Annual Eye Exam - 3 Reasons Why It Is Important!

Before you go through this, just close your eyes for a few seconds and ponder how your life would be if you are unable to see? Pathetic isn’t it? Eyes are one of the greatest gifts from the almighty, and it is your sole responsibility to protect them and keep in optimal health so that you too can keep on enjoying the beauty of nature.

Sometimes people are too lazy to go for an eye checkup when there is absolutely no vision problem and in other cases, people just don’t feel it is important to go for an eye checkup once in a year. However, routine eye exams are crucial for every person regardless of the age, gender, origin or habits. It is not just for individuals with poor eyesight but for everyone with or without eye problems. Here are the top reasons why you must be paying a visit to an ophthalmologist.

  1. Getting the prescription updated: You may think that your eyes are fine and there is nothing reasonable in visiting an ophthalmologist. But it is a general human tendency to neglect things until it is so late that nothing can be recovered. And your eyesight and eye health is no child’s play- it is vital in directing the quality of your life. The skilled ophthalmologist can monitor the condition of your eyes and follow up the changes that have taken place over time. Your eyes and their features are unique, and thus it becomes easier for the expert to detect what’s been altered in them.
  2. Seeing to the best of your abilities: People with corrective lenses often experience the need for tracking the periodic changes that have already taken place. Your eyes alter their shape and condition with time. Thus, keeping your prescription updated offers a subtle yet crucial advantage that you may not have considered before. Some of them are even concerned with your safety such as your ability to see while you drive at night.
  3. Eye diseases can be secretive: Sometimes, vision issues can come in quickly but often eye disorders tend to creep up that most individuals are not able to see. The deterioration can be so subtle and slow that you are unable to detect anything until it has progressed to a great extent. Eye diseases such as diabetic retinopathy and glaucoma typically have no symptoms, which can be detected at an early age.

And it goes without saying that vision loss cannot be reversed. But in case you visit your ophthalmologist regularly from an early age, vision loss can be prevented or at least slowed down.

My mother have diabetes from past 12 years, also have diabetic retinopathy since 3 years, hypertension since 4 years ...
Diabetes is a condition which can cause many problems. Control of blood sugar, blood pressure and other things like weight loss and dietary advice are essential. A good diabetologist or Endocrinologist should be able to advise your mother about these things. As far as the retinopathy is concerned I would need to see details of her vision and eye examination findings, to be able to give any meaningful advise.
