What is diabetic retinopathy?
Diabetic retinopathy is a diabetes-related eye disease that affects the retina, the light-sensitive tissue at the back of the eye. It is a leading cause of vision loss and blindness among individuals with diabetes. Diabetic retinopathy develops due to changes in the blood vessels of the retina, primarily as a result of prolonged high blood sugar levels.
Stages of diabetic retinopathy
Non-proliferative Diabetic Retinopathy (NPDR)
This is the early stage where small blood vessels in the retina weaken and leak fluid or blood. At this stage, vision may not be significantly affected, but it requires monitoring.
Proliferative Diabetic Retinopathy (PDR)
In this advanced stage, new blood vessels grow on the surface of the retina. These new vessels are fragile and can bleed into the vitreous, the gel-like substance that fills the center of the eye. Scar tissue may form, leading to retinal detachment and severe vision loss.

What are the risk factors?
- Duration of Diabetes: The longer a person has diabetes, the higher the risk of developing diabetic retinopathy.
- Blood Sugar Control: Poorly controlled blood sugar levels increase the risk.
- Blood Pressure Levels: High blood pressure is a risk factor for diabetic retinopathy.
- Cholesterol Levels: Elevated cholesterol levels can contribute to the progression of the disease.
Diabetic retinopathy symptoms
Initially, there may be no noticeable symptoms in the early stages. As the disease progresses, individuals may experience:
- Blurred or fluctuating vision
- Floaters (dark spots or strings in the vision)
- Difficulty seeing well at night
- Loss of central vision
Prevention and treatment
Regular comprehensive eye exams
Individuals with diabetes should have regular eye exams to detect and manage diabetic retinopathy early.
Blood Sugar Control
Maintaining optimal blood sugar levels is crucial.
Blood Pressure Control
Managing blood pressure is important for preventing and slowing the progression of diabetic retinopathy.

Cholesterol Management
Controlling cholesterol levels is beneficial.
Laser Therapy
Laser treatment may be used to seal leaking blood vessels or to shrink abnormal blood vessels.

Intravitreal Injections
Medications injected into the eye may help reduce swelling or prevent the growth of abnormal blood vessels.

Vitrectomy
In advanced cases, surgery may be necessary to remove blood and scar tissue from the eye.
Early detection and management of diabetic retinopathy are crucial for preserving vision! Regular eye examinations, good blood sugar control, and proactive management of other health factors contribute to preventing or slowing the progression of this condition. If you have diabetes, it's essential to work closely with your healthcare team, including your Execuspecs optometrist, to monitor and manage your eye health effectively.
