Diabetic Retinopathy
What is Diabetic Retinopathy?
Diabetic retinopathy is a serious eye condition that can occur in people with diabetes. It happens when high blood sugar levels damage the blood vessels in the retina (the light-sensitive part at the back of the eye). Over time, these damaged vessels can leak fluid or blood into the retina, leading to vision problems. If untreated, diabetic retinopathy can lead to blindness. Diabetic retinopathy is one of the leading causes of blindness in adults.However, the good news is that with early detection and proper treatment, it can often be managed, and vision loss can be prevented.
Types of Diabetic Retinopathy
There are two primary stages:
Non-Proliferative Diabetic Retinopathy (NPDR): This initial stage is characterized by weakened retinal blood vessels without the growth of new vessels.
Proliferative Diabetic Retinopathy (PDR): In this advanced stage, abnormal new blood vessels develop in the retina, which can leak blood and fluid, leading to more severe vision issues.
What is Diabetic Macular Edema (DME)?
A complication of diabetic retinopathy, Diabetic Macular Edema affects the macula—the central region of the retina responsible for sharp vision. In DME, damaged blood vessels leak fluid into the macula, causing swelling and resulting in blurred or distorted central vision. DME can occur during either NPDR or PDR stages.
Symptoms of Diabetic Retinopathy
Early stages of diabetic retinopathy often present no noticeable symptoms, making regular eye examinations crucial for individuals with diabetes. As the condition advances, symptoms may include:
Blurred or Distorted Vision: A decrease in visual clarity.
Floaters: Dark spots or strings that drift in the field of vision.
Sudden Vision Loss: Particularly in advanced cases where new retinal blood vessels bleed.
Symptom severity doesn’t always correlate with disease progression; significant damage can exist even with good vision. Therefore, routine eye checkups with a retina specialist are vital for early detection. Learn more about Retina Treatment.
How is Diabetic Retinopathy Diagnosed?
For those with diabetes, regular eye exams are imperative, even in the absence of symptoms. Diagnostic procedures include:
Visual Acuity Test: Assessing the sharpness of vision.
Dilated Eye Exam: Using drops to widen pupils, allowing detailed examination of the retina and blood vessels.
Fundus Photography: Capturing detailed images of the retina to monitor changes or damage.
Optical Coherence Tomography (OCT): Non-invasive imaging providing cross-sectional views of the retina to detect fluid accumulation or swelling.
Fluorescein Angiography: Injecting a dye into the bloodstream to highlight leaking or damaged retinal blood vessels.
Managing and Treating AMD
The primary goal in treating diabetic retinopathy is to prevent further retinal damage and preserve vision. Treatment strategies depend on the condition’s stage and severity:
Blood Sugar Control: Maintaining optimal blood sugar levels is crucial. Consistently high levels can exacerbate retinal damage. Strategies include adhering to medical advice on diet, exercise, and medications, regular blood sugar monitoring, and collaborating with healthcare providers to achieve target levels.
Monitoring and Lifestyle Adjustments: Regular eye exams are essential for early detection. Lifestyle modifications such as quitting smoking, managing blood pressure and cholesterol, and consuming a balanced diet rich in fruits, vegetables, and whole grains support overall health and eye wellness.

Medical Treatments:
Laser Therapy:
Focal Laser Treatment: Seals leaking retinal blood vessels to prevent further vision loss and reduce swelling.
Panretinal Photocoagulation: Targets and destroys abnormal blood vessels in advanced stages to prevent bleeding and reduce vision loss risk.
Injections:
Anti-VEGF Injections: Medications like Avastin, Accentrix, or Eylea inhibit the growth of abnormal blood vessels.
Steroid Injections: Agents such as Ozurdex reduce retinal inflammation and swelling, particularly in DME cases.
Vitrectomy: A surgical procedure to remove blood and scar tissue from the vitreous gel inside the eye, often necessary in advanced diabetic retinopathy stages.
Ongoing Care and Monitoring

Given the progressive nature of diabetic retinopathy, consistent follow-up is essential:
Regular Eye Examinations: Annual or more frequent exams based on disease progression.
Systemic Health Management: Controlling blood sugar, blood pressure, and cholesterol levels to slow disease advancement.
Lifestyle Modifications: Engaging in regular physical activity, maintaining a healthy diet, and avoiding smoking contribute to better eye health and overall well-being.
