What are different categories of diabetic retinopathy?

The four stages of diabetic retinopathy (DR) are mild nonproliferative diabetic retinopathy (NPDR), moderate nonproliferative diabetic retinopathy, severe nonproliferative diabetic retinopathy, and proliferative diabetic retinopathy (PDR).

What percentage of diabetics have diabetic retinopathy?

Diabetic retinopathy is the most frequent cause of new cases of blindness among adults aged 20–74 years. During the first two decades of disease, nearly all patients with type 1 diabetes and >60% of patients with type 2 diabetes have retinopathy.

Is retinopathy associated with type 2 diabetes?

Diabetic retinopathy was found in 23.9% of type 2 diabetics which was significantly associated with male gender, duration of diabetes, older age, high cholesterol, high LDL, albuminuria and insulin therapy.

What is the difference between PDR and NPDR?

Diabetic retinopathy falls into two main classes: nonproliferative and proliferative. The word “proliferative” refers to whether or not there is neovascularization (abnormal blood vessel growth) in the retinaEarly disease without neovascularization is called nonproliferative diabetic retinopathy (NPDR).

How long does it take to go blind from diabetic retinopathy?

Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back of the eye (retina). It can cause blindness if left undiagnosed and untreated. However, it usually takes several years for diabetic retinopathy to reach a stage where it could threaten your sight.

What does a person with diabetic retinopathy see?

Diabetic retinopathy is blood vessel damage in the retina that happens as a result of diabetes. Diabetic retinopathy can cause a range of symptoms, including blurred vision, difficulty seeing colors, and eye floaters. Without treatment, it can cause vision loss.

How fast does diabetic retinopathy progress?

Typically, diabetic patients will develop diabetic retinopathy after they have had diabetes for between 3-5 years. In the early stages, diabetic retinopathy will not affect the sight, but if it is not treated and progresses, eventually the sight will be affected.

Can lowering blood sugar improve vision?

While high blood sugar can change the shape of the lens in your eye, low blood sugar doesn’t and this particular vision issue can be corrected sooner by getting your blood sugar back to normal from a meal or snack.

How quickly does retinopathy progress?

Typically, diabetic patients will develop diabetic retinopathy after they have had diabetes for between 3-5 years.

How fast does retinopathy progress?

With moderate nonproliferative diabetic retinopathy, it’s about 20 to 40%. In the severe form of nonproliferative diabetic retinopathy, it can progress to proliferative diabetic retinopathy up to 60% of the time within 12 months.

Does retinopathy always lead to blindness?

It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy might cause no symptoms or only mild vision problems. But it can lead to blindness.

What is the prognosis of diabetic retinopathy?

Prognosis of Diabetic Retinopathy: At least 90% of these new cases could be reduced if there was proper and vigilant treatment and monitoring of the eye. Onset of Diabetic Retinopathy: After 20 years of diabetes, nearly all patients with type 1 diabetes and >60% of patients with type 2 diabetes have some degree of retinopathy.

How many people have diabetic retinopathy?

About 7 percent of the population of the United States has diabetes, and many people with diabetes go on to develop retinopathy. So it’s estimated now that over four million people in our country have diabetic retinopathy. The retina is a light sensitive tissue that lines the inside of the eye,…

What you should know about diabetic retinopathy?

Diagnosis. Diabetic retinopathy is best diagnosed with a comprehensive dilated eye exam.

What exams can help to diagnose diabetic retinopathy?

How is diabetic retinopathy diagnosed? Tonometry. A standard test that checks the pressure (intraocular pressure, or IOP) inside the eye. Pupil dilation. An examination where your pupil is widened with eye drops for a close-up of the eye’s lens and retina. Ophthalmoscopy. Fluorescein angiography. Optical coherence tomography.
