Risk Factors For Diabetic Retinopathy

Causes of Eye Problems: High Blood Sugar & Insulin Dr. Berg

Anyone with type 1, type 2, or gestational diabetes can develop diabetic retinopathy. The longer you have diabetes, the more likely you are to develop it. These factors can also increase your risk:

  • Blood sugar, blood pressure, and cholesterol levels that are too high.
  • Race/ethnicity: African Americans, Hispanics/Latinos, and American Indians/Alaska Natives are at higher risk.

If you have diabetic retinopathy, low-vision aids such as magnifying glasses and special lenses can help. Ask your eye doctor to refer you to a low-vision specialist.

When To See A Medical Provider

Blurry vision can be common, and in many cases, it is short-lived. Fatigue, poor sleep, allergies, and outdated glasses prescriptions can all contribute to short-term blurry vision. If you have diabetes, low or high blood glucose levels can cause brief changes to vision.

You should consult a medical provider if you notice vision changes that last longer than a few hours or if they happen consistently for short periods of time. If vision suddenly changes or is accompanied by other symptoms, like confusion, severe headache, or other abnormal signs, seek emergency medical care.

Other Types Of Diabetic Eye Disease

Diabetic retinopathy is the most common cause of vision loss for people with diabetes. But diabetes can also make you more likely to develop several other eye conditions:

  • Cataracts. Having diabetes makes you 2 to 5 times more likely to develop cataracts. It also makes you more likely to get them at a younger age. Learn more about cataracts.
  • Open-angle glaucoma. Having diabetes nearly doubles your risk of developing a type of glaucoma called open-angle glaucoma. Learn more about glaucoma.

Hyperinsulinemic Hypoglycemic And Euglycemic Clamp Procedure

Participants arrived at the Clinical Research Unit after an overnight fast. Vital signs were recorded and an intravenous catheter inserted in the left hand dorsal vein in a retrograde fashion for blood glucose sampling. The hand was placed in the hand warming box maintained at 55° C to arterialize the venous blood . Another intravenous catheter was inserted in the right antecubital vein for insulin and 20% dextrose infusion. Glucose levels were measured every five minutes at the bedside using the glucose oxidase method . A primed continuous infusion of 80- mU · m2· min1 of Regular human insulin was used 20% dextrose infusion was adjusted to achieve euglycemia with a target blood glucose level of 90 110 mg/dl . After an equilibration phase of 45 minutes, the 20% dextrose infusion rate was decreased slowly over a period of 4560 minutes to attain hypoglycemia with a target blood glucose level of 50 55 mg/dl . The hypoglycemic phase was maintained for 20 minutes. The rate of dextrose infusion was then increased over 3045 minutes to re-attain euglycemia. Subjects were offered meals at the conclusion of the study. Subjects remained rested and blinded to their blood glucose concentrations throughout the study.

How Diabetes Affects Your Vision

Diabetes is a disease affecting your pancreas, which also affects the blood sugar and insulin levels in your body. Not only does diabetes affect your pancreas, but it also systemically affects your entire body. Typically, people already know that diabetes increases your risk of heart disease and stroke but, most people dont know that diabetes can also affect your vision. Therefore, regular comprehensive eye exams are needed to detect these issues early on to keep your eyes healthy. There are several eye diseases that occur as a result of diabetes. Read on to find out more about these diseases and how they may affect your vision.

Diabetic retinopathy

The simplest way to explain diabetic retinopathy is that small blood vessels in your eyes begin to leak blood or yellow fluid into your eye. Early symptoms of diabetic retinopathy include having floaters, blurry vision, or distorted vision. If blurred vision or other symptoms dont clear up with improved blood sugar control, oftentimes medicine and other procedures may restore vision. The biggest preventative to diabetic retinopathy is management of blood sugar to normal levels and getting regular eye exams to catch the condition as early as possible. Diabetic retinopathy is the leading cause of blindness in diabetics.

Complications Of Diabetic Retinopathy

Diabetic retinopathy complications can result in serious vision problems, including:

Vitreous haemorrhage: It occurs when new blood vessels start to bleed into the vitreous fluid. When this complication is minor, you may see floaters. However, in severe haemorrhage, blood fills the vitreous cavity and temporarily blocks the vision completely. This complication takes a few weeks or months to clear unless the retina is damaged.

Glaucoma: Diabetic retinopathy causes new blood vessels to grow in the front of the eye as well. This results in a buildup of eye pressure and interference with the normal fluid flow. Glaucoma can damage the optic nerve and can lead to permanent blindness.

Retinal detachment: When damaged blood vessels pull the retina away from the support tissue, retinal detachment occurs. In this condition, you may observe floaters and flashes of light initially and then complete obscuration of vision.

Regular Eye Exams Are Important

All people with diabetes are at risk for diabetic retinopathy. Diabetic retinopathy develops over time and often goes unnoticed until vision loss occurs.

Following your diabetes ABCDEs and getting your eyes checked regularly by an ophthalmologist or optometrist are crucial to prevent vision loss or keep it from getting worse.

If you have diabetic retinopathy, very effective treatments are available. Your eye-care specialist will explain these to you.

A Study Conducted By State University Of New York Upstate Medical University Demonstrated That Chronic Hypoglycemia Can Lead To Vision Loss

Chronic low blood sugar led to loss of retinal function and also retinal cell death

The retina is the light-sensitive tissue at the back of the eye. It is part of the eye that can be affected by diabetes. The study, conducted on lab mice that were genetically predisposed to hypoglycemia, proved that chronic low blood sugar led to loss of retinal function and also retinal cell death.

The study, which was published in the Proceeding of National Academy of Sciences, is the first to demonstrate the stresses on an animals eye caused by chronic low blood sugar. When researchers restored blood sugar to normal levels in the test mice, vision loss was delayed by several months.

These conclusions seem to validate the belief that good blood sugar control can reduce retinal deterioration caused by diabetic retinopathy. This is especially important to diabetics who are susceptible to hypoglycemia due to ongoing insulin treatment.

Treating An Episode Of Hypoglycaemia

The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.

For example, this could be:

  • a glass of fruit juice or non-diet soft drink
  • between three and five dextrose tablets
  • a handful of sweets

At first you should avoid fatty foods and drinks, such as chocolate and milk, because they donât usually contain as much sugar and the sugar they do contain may be absorbed more slowly.

After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.

It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If itâs still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.

When treating someone else with hypoglycaemia, if the above treatment isnât effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.

It may take 10 to 15 minutes before they feel better. This shouldnât be done if the person is drowsy or unconscious because of the risk of choking.
