Which of the following is a type 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 is the correlation between diabetes and eye disorders?

Diabetes can lead to swelling in the macula, which is called diabetic macular edema. Over time, this disease can destroy the sharp vision in this part of the eye, leading to partial vision loss or blindness. Macular edema usually develops in people who already have other signs of diabetic retinopathy.

What happens diabetic retinopathy?

In the early stages of diabetic retinopathy, the walls of the blood vessels in your retina weaken. Tiny bulges protrude from the vessel walls, sometimes leaking or oozing fluid and blood into the retina. Tissues in the retina may swell, producing white spots in the retina.

When does diabetic retinopathy occur?

Although retinopathy usually does not appear for approximately five years after a type 1 diabetes diagnosis, it may already be present when type 2 diabetes is diagnosed. After 15 years of having diabetes, 98 percent of those with type 1 diabetes and 78 percent of those with type 2 have some degree of retinal damage.

How is diabetic retinopathy diagnosed?

Diabetic retinopathy is best diagnosed with a comprehensive dilated eye exam. For this exam, drops placed in your eyes widen (dilate) your pupils to allow your doctor a better view inside your eyes. The drops can cause your close vision to blur until they wear off, several hours later.

What is proliferative diabetic retinopathy?

PDR (proliferative diabetic retinopathy) PDR is the more advanced stage of diabetic eye disease. It happens when the retina starts growing new blood vessels. This is called neovascularization. These fragile new vessels often bleed into the vitreous. If they only bleed a little, you might see a few dark floaters.

How does diabetes cause diabetic nephropathy?

Diabetic nephropathy causes Diabetic nephropathy is a common complication of type 1 and type 2 diabetes. Over time, poorly controlled diabetes can cause damage to blood vessel clusters in your kidneys that filter waste from your blood. This can lead to kidney damage and cause high blood pressure.

What is stage 3 diabetic retinopathy?

Stage 3: Severe nonproliferative diabetic retinopathy A larger section of blood vessels in the retina become blocked, causing a significant decrease in blood flow to this area. At this point, the body receives signals to start growing new blood vessels in the retina.

What is the first stage of diabetic retinopathy?

The first stage is also called background retinopathy. It means that there are tiny bulges in the tiny blood vessels in your retinas. The bulges are called microaneurysms. They may cause the vessels to leak small amounts of blood into your retinas.

Can you recover from diabetic retinopathy?

There is no cure for diabetic retinopathy. But treatment works very well to prevent, delay, or reduce vision loss. The sooner the condition is found, the easier it is to treat.

Which client is at the highest risk for diabetic retinopathy?

People with type 1 or type 2 diabetes are at risk for developing diabetic retinopathy. The longer a person has diabetes, the more likely he or she is to develop diabetic retinopathy, particularly if the diabetes is poorly controlled.

How does diabetic retinopathy affect daily life?

Difficulty driving, especially at night, and trouble reading were noted with all levels of severity. Participants with PDR and decreased visual acuity have foregone many other important life aspects such as work, reading and sports.

What is retinopathy?

Retinopathy means disease of the retina. There are several types of retinopathy but all involve disease of the small retinal blood vessels.

How does hyperglycemia cause retinopathy?

Diabetic retinopathy is caused by prolonged high blood glucose levels Over time, high sugar glucose levels can weaken and damage the small blood vessels within the retina. This may cause haemorrhages, exudates and even swelling of the retina. This then starves the retina of oxygen, and abnormal vessels may grow.

What percentage of diabetics have diabetic retinopathy?

A high prevalence of diabetic retinopathy, that is 54.2%, was determined in the Diabetes Control and Complication Study (DCCT), which comprised DM1 patients from the USA and Canada [35,36].

Who checks for diabetic retinopathy?

Regular dilated eye exams by an ophthalmologist are important, especially for those who are at a higher risk for diabetic retinopathy or diabetes. If you are over age 50, an exam every year is a good idea so the eye physician can look for signs of diabetes or diabetic retinopathy before any vision loss has occurred.

How do people live with diabetic retinopathy?

Living with diabetic retinopathy Keep your blood sugar at an appropriate level with the help of your doctor. Go in for a thorough eye exam every year or as recommended by your doctor. Doing these things can prevent vision loss even if you have been diagnosed with diabetic retinopathy.

When should a Type 2 diabetic be screened for retinopathy?

Eye examinations should occur before pregnancy or in the first trimester in patients with preexisting type 1 or type 2 diabetes, and then patients should be monitored every trimester and for 1 year postpartum as indicated by the degree of retinopathy.

What causes proliferative retinopathy?

Proliferative retinopathy (see Table 2-3) develops when the retinal vessels are further damaged, causing retinal ischemia. The ischemia triggers new, fragile vessels to develop, a process termed neovascularization.

What does proliferative retinopathy mean?

Proliferative retinopathy is a developed form of retinopathy whereby new but weak blood vessels begin to form on the retina to help restore blood supply.
