It causes progressive damage to the retina, the light-sensitive lining at the back of the eye. Diabetic retinopathy is a serious sight-threatening complication of diabetes.
Diabetes interferes with the body''t know whether diabetic eye diseases have visible symptoms (often which the early stages of diabetic retinopathy does not). The same survey found that more than one-third of Americans didn''s diabetes will cause blindness, which is why the AOA recommends that everyone with diabetes have a comprehensive dilated eye examination at least once a year. Early detection and treatment can limit the potential for significant vision loss from diabetic retinopathy.
Treatment of diabetic retinopathy varies depending on the extent of the disease. People with diabetic retinopathy may need laser surgery to seal leaking blood vessels or to discourage other blood vessels from leaking. Your doctor of optometry might need to inject medications into the eye to decrease inflammation or stop the formation of new blood vessels. People with advanced cases of diabetic retinopathy might need a surgical procedure to remove and replace the gel-like fluid in the back of the eye, called the vitreous. Surgery may also be needed to repair a retinal detachment. This is a separation of the light-receiving lining in the back of the eye.
If you are diabetic, you can help prevent or slow the development of diabetic retinopathy by:
- Taking your prescribed medication
- Sticking to your diet
- Exercising regularly
- Controlling high blood pressure
- Avoiding alcohol and smoking
What causes diabetic retinopathy?
Diabetic retinopathy results from the damage diabetes causes to the small blood vessels located in the retina. These damaged blood vessels can cause vision loss:
- Fluid can leak into the macula, the area of the retina responsible for clear central vision. Although small, the macula is the part of the retina that allows us to see colors and fine detail. The fluid causes the macula to swell, resulting in blurred vision.
- In an attempt to improve blood circulation in the retina, new blood vessels may form on its surface. These fragile, abnormal blood vessels can leak blood into the back of the eye and block vision.
diabetes type 2 vision problems quick fix (👍 with hyperglycemia) | diabetes type 2 vision problems and covid 19how to diabetes type 2 vision problems for Diabetic retinopathy is classified into two types:
- Non-proliferative diabetic retinopathy (NPDR) is the early stage of the disease in which symptoms will be mild or nonexistent. In NPDR, the blood vessels in the retina are weakened. Tiny bulges in the blood vessels, called microaneurysms, may leak fluid into the retina. This leakage may lead to swelling of the macula.
- Proliferative diabetic retinopathy (PDR) is the more advanced form of the disease. At this stage, circulation problems deprive the retina of oxygen. As a result, new, fragile blood vessels can begin to grow in the retina and into the vitreous, the gel-like fluid that fills the back of the eye. The new blood vessels may leak blood into the vitreous, clouding vision.
Other complications of PDR include detachment of the retina due to scar tissue formation and the development of glaucoma. Glaucoma is an eye disease in which there is progressive damage to the optic nerve. In PDR, new blood vessels grow into the area of the eye that drains fluid from the eye. This greatly raises the eye pressure, which damages the optic nerve. If left untreated, PDR can cause severe vision loss and even blindness.
Risk factors for diabetic retinopathy include:
- Diabetes. 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.
- Race. Hispanics and African Americans are at greater risk for developing diabetic retinopathy.
- Medical conditions. People with other medical conditions, such as high blood pressure and high cholesterol, are at greater risk.
- Pregnancy. Pregnant women face a higher risk for developing diabetes and diabetic retinopathy. If a woman develops gestational diabetes, she has a higher risk of developing diabetes as she ages.

How is diabetic retinopathy diagnosed?
Diabetic retinopathy can be diagnosed through a comprehensive eye examination. Testing, with emphasis on evaluating the retina and macula, may include:
- Patient history to determine vision difficulties, presence of diabetes, and other general health concerns that may be affecting vision
- Visual acuity measurements to determine how much central vision has been affected
- Refraction to determine if a new eyeglass prescription is needed
- Evaluation of the ocular structures, including the evaluation of the retina through a dilated pupil
- Measurement of the pressure within the eye
Supplemental testing may include:
- Retinal photography or tomography to document the current status of the retina
- Fluorescein angiography to evaluate abnormal blood vessel growth
How is diabetic retinopathy treated?
Treatment for diabetic retinopathy depends on the stage of the disease. The goal of any treatment is to slow or stop the progression of the disease.
In the early stages of non-proliferative diabetic retinopathy, regular monitoring may be the only treatment.

Injections of medication in the eye are aimed at discouraging the formation of abnormal blood vessels and may help slowdown the damaging effects of diabetic retinopathy.
If the disease advances, the abnormal blood vessels can leak blood and fluid into the retina, leading to macular edema. Laser treatment (photocoagulation) can stop this leakage. A laser beam of light creates small burns in areas of the retina with abnormal blood vessels to try to seal the leaks.
Widespread blood vessel growth in the retina, which occurs in proliferative diabetic retinopathy, can be treated by creating a pattern of scattered laser burns across the retina. This causes abnormal blood vessels to shrink and disappear. With this procedure, some side vision may be lost in order to safeguard central vision.
