Dilated Eye Exam- What Is The Definition of Dilated Eye Exam

 

What Is the Definition of A Dilated Eye Exam

Getting a comprehensive dilated eye exam is one of the best things you can do to keep your eyes healthy. In this painless procedure, an eye care professional examines your eyes to look for common vision problems and eye diseases, many of which have no early warning signs.

Different from the basic eye exam one has to get for glasses or contact lenses, comprehensive dilated eye exams can help protect your sight by making sure you are seeing your best and detecting eye diseases in their early stages, before vision loss has occurred.

A comprehensive dilated eye exam includes the following:

Dilation—Drops are placed in your eyes to dilate, or widen, the pupils. Your eye care professional uses a special magnifying lens to examine your retina to look for signs of damage and other eye problems, such as diabetic retinopathy or age-related macular degeneration. A dilated eye exam also allows your doctor to check for damage to the optic nerve that occurs when a person has glaucoma. After the examination, your close-up vision may remain blurred for several hours.

Tonometry—This test helps to detect glaucoma by measuring eye pressure. Your eye care professional may direct a quick puff of air onto the eye, or gently apply a pressure-sensitive tip near or against the eye. Numbing drops may be applied to your eye for this test. Elevated pressure is a possible sign of glaucoma.

Visual field testt—This test measures your side (peripheral) vision. It helps your eye care professional find out if you have lost side vision, a sign of glaucoma.

Visual acuity test—This eye chart test measures how well you see at various distances.

Diabetes and Flu Vaccine Side Effects

Are Diabetics More Likely to Suffer Flu Vaccine Side Effects?

[box] What You Need To Know About Diabetes and Flu Vaccine Side Effects

  • Diabetics tolerate the flu vaccine the same as patients without diabetes.
  • The flu vaccine is safe.
  • The flu vaccine does not cause the flu.
  • The flu vaccine does not lead to changes in glucose control.

What You Need To Do About Diabetes and Flu Vaccine Side Effects

  • Get the flu shot, not the nasal mist vaccine.
  • Take precautions to prevent getting the flu.

In general diabetes patients tolerate the flu vaccine without significant side effects. Based on available data, the flu vaccine appears to be safe and low risk. Common flu vaccine side effects include:

  • Soreness
  • Pain at the injection site
  • Redness or swelling at the injection site
  • Low grade fever
  • Myalgias or muscle aches
  • Headaches

Less common but significant flu vaccine side effects can occur:

  • Severe allergic reaction like anaphylaxis.
  • Guillain-Barre syndrome- a neurological disorder that occurs i about 1 in 1 million people receiving the flu vaccine.

Patients over the age of 65 now often recieve a higher dose inactivated vaccine and stomach problems, especially vomiting, have been reported as a flu vaccine side effect.

Should I Say No If I Have Egg Allergy?

If you have a severe reaction to eggs it is probably reasonable to refuse the flu vaccine.

I am Diabetic And Pregnant: What About Flu Vaccine Side Effects?

If you are pregnant it is important for you to get the flu vaccine because pregnant women develop more severe illness if they get the flu. The flu vaccine has not been shown to affect either mom or baby adversely.

Talk with your health care provider because they may have a preference as to when you receive your vaccine. The flu vaccine does not increase the risk of miscarriage and is not known to cause birth defects. Additionally, the flu vaccine may actually protect a newborn from getting the flu during the first few months of life, and has no effect on mom’s ability to breast feed.

Overall, there do not appear to be any specific concerns related to flu vaccine side effects for pregnant women- diabetic or not.

Is Getting Flu One Of The Flu Vaccine Side Effects?

While sore throat, fever, achiness, and soreness are sometimes reported following a flu vaccination, the flu shot is made from a killed virus. This means that you cannot the flu from getting the flu shot.

What Can I Do To Prevent Flu Vaccine Side Effects

Since the most common side effects are pain at the injection site and fever, a common over the counter pain medication like Tylenol (acetaminophen) or Advil (ibuprofen) will prevent you from experiencing either. Ask your health care provider for one before your injection, or bring one with you to your appointment.

Autoimmune Disease

What Is the Definition of An Autoimmune Disease

Type 1 diabetes is an autoimmune disease. This means that the powerful cells of your immune system that normally fight off infections as a foreign invaders turn around and actually attack parts of your body thinking they are foreign. In type 1 diabetes your body senses the beta cells of the pancreas as foreign and attacks them. The destruction of the beta cells cause your pancreas to not produce insulin and  leads to the symptoms of diabetes.

Why an autoimmune disease causes your body to sense something as foreign is not very well understood. There are a number of possible factors that could contribute to the development of an autoimmune disease including:
•    Genetic factors
•    Environmental factors
•    Infectious triggers

While type 1 diabetes is an autoimmune disease, type 2 diabetes and gestational diabetes are not an autoimmune disease.

HbA1C

 

What Is The Definition of HbA1c?

[box]

What You Need to Know About Your HbA1c

  • You need to know your HbA1c to understand your control.
  • If your diabetes is well controlled, you may only need a HbA1c test twice per year.
  • Your HbA1c goal is 7% or less.

What You Need to Do–Your HbA1c

  • See a doctor to discuss your HbA1c.
  • Follow your diabetic plan based on your HbA1c results.

[/box]

What Is the HbA1C?
Think of your HbA1C as a summary of how your diabetes has been doing over the last several months. The HbA1C test uses your blood sugar to see how well or poorly your diabetes control has been.
The HbA1C measures how much sugar attaches to your red blood cells. Because red blood cells stay in your body for about 3 months, the HbA1C test can measure your diabetes control for about the last 3 months.

What Should My HbA1C Be?
This depends on who you ask, but the lower your HbA1C the better. The American Diabetes Association recommends a HbA1C of less than 7%, while the American Association of Clinical Endocrinologists (doctors that are diabetes specialists) recommend a level of 6.5% or less. The lower you can get your HbA1C,  the less likely you will develop complications. You and your doctor should discuss your goal HbA1C as your age, other medical problems, and risk of hypoglycemia all will affect your target HbA1C.

What Does An Elevated HbA1C Mean?
When your HbA1C is elevated, you increase your risk of diabetes complications. The Diabetes Control and Complications Study demonstrated that your risk of complications from diabetes rises as your HbA1C increases.

How Often Should I Get a HbA1C?
The HbA1c is one of the most important numbers you need to understand about your diabetes. You can think of the HbA1c as a summary of how your blood sugar control has been over the last several months. While you may check and measure your blood sugar several times per day, the A1C determines how well your blood sugar has been controlled over the last 2-3 months.

While your daily checks of your blood sugar are a quick check of your diabetes control, the A1C test is the most accurate measure of your diabetes control. If your diabetes is under good control, you may only need the A1C test twice per year. If your diabetes is not as well controlled, your healthcare provider may check the A1C more often.

Your doctor can often preform the A1C test right in the office and you do not need to avoid eating before you have the A1C test done.

What Does My A1C Mean?
Your goal A1C will depend on a number of factors like age, other medical conditions, and risk of hypoglycemia. In general, your doctor would like to see your A1C less than 7%. When your A1C is at this level, your diabetes plan is working well. In general, the lower your A1C, the less your risk of developing complications. As a result, your doctor may push you to get your A1C even lower.

Why Does Lowering My A1C Matter?
Lowering your A1C decreases your risk of diabetic complications with your:

  • Eyes
  • Kidneys
  • Nerves
  • Heart

For every 1% you lower your A1C, you significantly decrease your risk of developing diabetes complications. In the United Kingdom Prospective Diabetes Study, lowering your Hba1c by 1% (e.g. 8% to 7%) decreases the risk of complications like eye disease by 21% and the risk dying by diabetes by more than 20%.

Tests Other Than A1C Your Doctor May Order

  • Creatinine
  • Thyroid
  • Electrocardiogram
  • Cholesterol

Have You Gotten Your Flu Shot?

I have never understood it, but I see many people who choose not to get flu shots despite knowing better.

Patients will tell me “I never get sick from the flu.” I will then tell them that past wellness is not necessarily indicative of future wellness and that the benefits for flu prevention significantly outweigh the risks. It is also still relatively common for people to to say “the flu shot gave me the flu.” While this is not technically possible for the flu injection, some patients do experience a low grade fever and achiness. Significant side effects from the flu shot are exceedingly rare. Finally, some patients just say, “I’ll get treated if I develop symptoms.”

What do you think about the flu shot? Do you have any other reasons for not wanting to get the flu shot? Do you have any words of encouragement for others not wanting to get the flu shot?

Take Action- Talk with your health care provider about the flu shot– it could be one of the best things you do for your health this year.
