Diabetic retinopathy

Diabetic retinopathy: Introduction

Diabetic retinopathy is a common complication of diabetes in which the blood vessels that supply oxygen to the retina of the eye are damaged due to long-term high levels of blood sugar (hyperglycemia). The retina is a light-sensitive membrane that lines the back of the eye and a healthy retina is vital to normal vision.

Diabetic retinopathy generally develops slowly over a period of months as ongoing high blood sugar levels damage the blood vessels of the retina. This leads to leaking or bleeding of the blood vessels or the growth of abnormal blood vessels. These processes can prevent light from reaching the retina. This leads to the typical symptoms of diabetic retinopathy, such as changes in vision, including blurred vision. There also may be eye pain in diabetic retinopathy. However, in early stages of diabetic retinopathy, there may be no noticeable symptoms.

In later stages of diabetic neuropathy, serious complications can result, including retinal detachment and blindness. For more details about complications and symptoms, see symptoms of diabetic retinopathy.

Diagnosing diabetic retinopathy begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination, including an extensive eye examination. Diagnosis of diabetic retinopathy is generally made by an eye specialist called an ophthalmologist.

An eye examination includes testing visual acuity or sharpness of vision, checking the sharpness of peripheral vision, and testing the pressure inside the eye. The outer eye is examined using an instrument called a slit lamp, and the inner eye is examined using an instrument called an ophthalmoscope. During the exam with an ophthalmoscope, the pupils of the eye are dilated (opened up) with a drop of medication so that the ophthalmologist can best see any changes in the retina that are signs of diabetic retinopathy such as leaking blood vessels, or abnormal new blood vessels.

A diagnosis of diabetic retinopathy and its cause can be delayed or missed because symptoms develop gradually. In addition, symptoms of diabetic retinopathy are similar to symptoms of other eye diseases and conditions. For information about disease and conditions that can mimic retinopathy, refer to misdiagnosis of diabetic retinopathy.

Prevention of diabetic retinopathy is very important for people with diabetes. The longer a person has diabetes, the more likely a person will develop diabetic retinopathy. Good control of blood sugar levels minimizes the risks of developing diabetic retinopathy and can slow progression of the condition.

Diabetic retinopathy: Misdiagnosis

A diagnosis of diabetic retinopathy and its underlying cause of diabetes may be delayed or missed because diabetic retinopathy generally develops gradually. In early stages, there may be no symptoms, and people may be unaware of having diabetes or diabetic retinopathy until complications, such as blurred vision, develop. In addition, some symptoms of diabetic retinopathy, such as ...more misdiagnosis »

Causes of Diabetic retinopathy:

The following medical conditions are some of the possible causes of Diabetic retinopathy. There are likely to be other possible causes, so ask your doctor about your symptoms.

  • Excessive alcohol - alcohol if used to extreme, reduces Vitamin B12 and thiamine levels. It is unclear what effect moderate alcohol has on retinopathy.
  • High cholesterol - cholesterol can exacerbate retinopathy and further damage in the small blood vessels of the eye, just as cholesterol can cause hardening of larger artery blood vessels.
  • Pregnancy - can exacerbate existing retinopathy though probably not cause it directly.

Article Excerpts about Diabetic retinopathy

This disorder can result from diabetes. It happens when small blood vessels stop feeding the retina properly. In the early stages, the blood vessels may leak fluid, which distorts sight. In the later stages, new vessels may grow and send blood into the center of the eye, causing serious vision loss. In most cases, laser treatment can prevent blindness. It is very important that people with diabetes have an eye exam through dilated pupils every year. (Source: excerpt from Aging and Your Eyes -- Age Page -- Health Information: NIA)
