Diabetic Retinopathy: Symptoms, Treatments, and How to Protect Your Vision

Diabetic retinopathy is an eye disease that affects people with diabetes and can lead to vision loss. At LUPER, we explain its symptoms, treatments, and how to prevent it to care for your visual health.

What is Diabetic Retinopathy?

Diabetic retinopathy is a complication of diabetes that affects the blood vessels of the retina, the light-sensitive tissue at the back of the eye. This condition can cause vision loss and, if left untreated, lead to blindness.

Types of Diabetic Retinopathy

Diabetic retinopathy is divided into two main types, each with different characteristics and levels of risk to vision:

1. Non-Proliferative Diabetic Retinopathy (NPDR)

This is the initial and commonly asymptomatic stage. NPDR occurs when the blood vessels in the retina begin to develop microaneurysms, leaking fluid and causing swelling. In more severe cases, it can lead to macular edema that affects central vision.

2. Proliferative Diabetic Retinopathy (PDR)

In PDR, the eye attempts to compensate for blocked vessels with new, abnormal blood vessels (neovascularization) that are fragile and tend to bleed. This can cause blurred vision, floaters, and even retinal detachment.

Symptoms of Diabetic Retinopathy

In the early stages, diabetic retinopathy may show no obvious symptoms, but as it progresses, the following may appear:

Blurred vision or fluctuations.
Floaters or spots in the visual field.
Difficulty seeing at night.
Dark or empty areas in vision.
Gradual vision loss.

Diagnosis of Diabetic Retinopathy

Early diagnosis is crucial to control this disease. Tests to detect diabetic retinopathy:

Dilated eye exam: Detection of early signs and detailed analysis of the retina.
Fluorescein angiography: An exam that allows visualization of blocked or leaking vessels.
Optical Coherence Tomography (OCT): Generates detailed images of the retina and detects swelling in the macula.

Treatments for Diabetic Retinopathy

Diabetic retinopathy has various treatment options depending on the stage of the disease:

1. Medical Control

Maintaining adequate levels of glucose and blood pressure can help prevent the progression of diabetic retinopathy.

2. Injected Medications (Anti-VEGF)

These drugs, such as Avastin or Lucentis, are injected directly into the eye to reduce macular swelling and decrease the growth of new blood vessels.

3. Laser Treatment

Laser treatment helps seal leaking vessels and reduces the growth of new abnormal vessels. This procedure is common in advanced proliferative retinopathy.

4. Vitrectomy Surgery

In severe cases, when there is excessive bleeding or retinal detachment, vitrectomy can remove the vitreous gel and scar tissue to restore visual clarity.

Complications of Diabetic Retinopathy

If left untreated, diabetic retinopathy can lead to serious complications, such as:

Diabetic Macular Edema (DME): Swelling in the macula, causing blurred vision.
Retinal Detachment: Scar tissue separates the retina from the eye.
Neovascular Glaucoma: Growth of blood vessels in the iris, blocking fluid drainage from the eye.
Blindness: Can occur in advanced cases if adequate treatment is not received.

Prevention of Diabetic Retinopathy

Prevention is essential to protect vision. Here are some tips to reduce the risk of developing diabetic retinopathy:

Control your glucose level: Perform regular checks and maintain stable blood sugar levels.
Manage your blood pressure and cholesterol: Keeping both under control helps prevent damage to retinal blood vessels.
Do not smoke: Smoking aggravates diabetes complications, including eye problems.
Annual eye exams: Get a dilated eye exam at least once a year.

Schedule your annual eye exams at LUPER for effective prevention.

Diabetic Retinopathy and Pregnancy

Pregnancy can increase the risk of diabetic retinopathy, especially in women with gestational diabetes. Recommendations during pregnancy include:

Eye exam in the first trimester.
Regular check-ups to monitor changes in the retina.
Rigorous control of glucose and blood pressure.

Differences between Diabetic Retinopathy and Hypertensive Retinopathy

Although both conditions affect the retina, diabetic retinopathy is caused by high blood glucose levels, while hypertensive retinopathy is due to poorly controlled high blood pressure. Both can coexist in people with diabetes and hypertension.

Frequently Asked Questions about Diabetic Retinopathy

1. What is proliferative diabetic retinopathy?

It is an advanced stage of retinopathy in which the eye develops new abnormal blood vessels in the retina that can bleed or cause scarring.

2. What are the initial symptoms of diabetic retinopathy?

Retinopathy may not present symptoms initially, but it can progress to blurred vision, floaters, and vision loss.

3. Is there a cure for diabetic retinopathy?

There is no cure, but treatments can control its progression and help protect vision.

4. Can I lose my vision completely?

Without adequate treatment, diabetic retinopathy can lead to blindness.

5. How often should I have an eye exam?

If you have diabetes, it is recommended to have a comprehensive dilated eye exam once a year.

6. Is laser surgery painful?

Laser treatment for retinopathy is usually painless and performed as an outpatient procedure.
