How Retina Specialists Treat Diabetes-Related Vision Problems

Diabetes can affect many parts of the body, including the eyes. High blood sugar can damage the small blood vessels that supply the retina, the light-sensitive tissue at the back of the eye. Over time, this damage can lead to diabetic retinopathy, diabetic macular edema, and other vision problems. Early diagnosis and appropriate diabetic retinopathy treatment can help protect vision and reduce the risk of serious complications. A retina specialist can evaluate the condition and recommend treatment based on how much the retina has been affected.

Understanding Diabetes-Related Eye Problems

Diabetic eye disease is a complication of diabetes that affects the retina. Blood vessels in the retina can become weakened and start to leak. It can be difficult to notice changes in the retina, which is why it is important for those with diabetes to have regular eye exams.

As diabetic retinopathy progresses, the abnormal blood vessels in the retina can swell and bleed. The blood vessels can also narrow, reducing blood flow to the retina. In later stages, fragile blood vessels may grow, and they can leak into the retina. Scar tissue may also form and pull on the retina, possibly detaching it.

The macula swells due to leaking fluid which causes vision to become distorted. The macula is located in the center of the retina, and allows us to see clearly.

How Retina Specialists Diagnose Diabetic Retinopathy

To evaluate the retina, a retina specialist can look at the back of the eye. The retinal specialist will use an instrument to look into the patient’s eye and examine the blood vessels, looking for any swelling, bleeding or abnormal blood vessels.

Other imaging tests may be performed. An optical coherence tomography (OCT) scan may be used to create images of the retina. An OCT lets the specialist see if there is any swelling or fluid in the retina, or other abnormalities not visible during an eye exam.

Another imaging technique, fluorescein angiography, may be used. A special dye is injected into the patient’s bloodstream, and photos are taken as the dye passes through the retina. This helps the specialist see blood vessels and identify any abnormalities.

Based on these tests, the retina specialist can determine what type and how severe a diabetic retinopathy is. They can then decide on the best course of treatment.

Monitoring Mild Diabetic Retinopathy

Not all diabetic retinopathy requires treatment. If the retina is only mildly affected and vision is not significantly impacted, the retina specialist may suggest monitoring the condition closely.

Periodic testing allows the retina specialist to observe any changes in the retina. The frequency with which these exams are done depends on how mild the diabetic retinopathy is, and the overall health of the retina.

It is also important to maintain good control of blood sugar levels. Managing blood sugar, blood pressure and cholesterol helps to ensure that diabetic eye disease does not worsen. The retina and the eyes are managed alongside control of the patient’s diabetes.

Anti-VEGF Injections for Retinal Swelling

If diabetic retinopathy includes abnormal blood vessel growth or diabetic macular edema, the retina specialist may recommend an anti-VEGF injection.

VEGF is a protein that causes abnormal blood vessel growth and increases permeability. Anti-VEGF drugs prevent VEGF from acting, reducing the effect of diabetic retinopathy on the retina.

An injection of anti-VEGF drugs can be placed directly in the eye. A small needle is used to inject the medication after numbing drops have been placed in the eye. The frequency of anti-VEGF injections depends on individual factors and the patient’s response. Patients may need several injections over several weeks, or regular injections to maintain improvements.

Anti-VEGF therapy suppresses abnormal blood vessel growth and reduces fluid buildup in the retina. This helps to maintain and perhaps improve vision.

Laser Treatment to Treat Diabetic Retinopathy

Laser treatment has been used for decades to treat diabetic retinopathy. There are still situations when laser surgery is useful, even though other medications are often used for diabetic retinopathy.

Panretinal photocoagulation is a form of laser surgery that is used to treat areas of the retina where abnormal blood vessels have formed. The laser creates small burns over the area of the retina that is not receiving enough blood flow. This reduces the retina’s need for blood, slowing abnormal blood vessel growth.

Laser surgery can also be used to directly treat abnormal blood vessels in specific instances. The type of laser treatment used depends on the location and severity of the diabetic retinopathy.

Treatment for Advanced Diabetic Retinopathy

In late-stage diabetic retinopathy, vision may be significantly impacted. Surgery may be used to treat complications like bleeding in the eye and retinal detachment.

Vitrectomy may be used to remove blood or scar tissue from the retina. A vitrectomy involves removing the vitreous from the eye. Scar tissue in the retina may also be removed with an additional surgical procedure. Surgery may be needed to reattach the retina if it has been detached.

It is important for those with diabetes to receive treatment if they experience vision loss, significant floaters, spots or shadows in their vision, or a curtain coming across their field of vision.

Why Retina Care Is Important

Diabetic retinopathy can develop and advance without obvious symptoms. Patients can have significant damage to the retina before vision is affected. Delays in treatment allow diabetic retinopathy to cause more damage to the retina.

The retina specialist can detect changes in the retina during a dilated eye exam. Based on the changes they see in the retina, the specialist can recommend continued monitoring, medication, laser treatment, or surgery to treat the retinal condition.

Patients with diabetes should make sure to have regular eye exams as advised by their retina specialist. Those who already have diabetic eye disease may need additional testing.

When Should You Visit a Retina specialist?

A patient may be referred to a retina specialist when diabetic retinopathy is more advanced or the retina swelling is impacting the patient’s vision. It may also be the case that more thorough testing is needed than what a general eye care practitioner is able to perform.

Those with diabetes or pre-diabetes should also receive care from a retina specialist if they exhibit symptoms like sudden worsening of vision, new floaters, flashes behind the eyes, dark spots or areas of vision loss, or a shadow passing over the field of vision. These symptoms can indicate a retinal problem that may need to be addressed.

A retina specialist is able to provide care and treatment specific to the needs of patients with diabetes and diabetic eye disease.

FAQs

1. Can diabetic retinopathy be treated?

Yes. Treatment depends on the stage and type of diabetic retinopathy. Options may include monitoring, anti-VEGF injections, laser treatment, or surgery for advanced disease.

2. Do diabetic retinopathy injections improve vision?

Anti-VEGF injections can reduce retinal swelling and leakage and may help stabilize or improve vision in patients with diabetic macular edema. Results vary depending on the severity and duration of the condition.

3. Can diabetic retinopathy cause permanent vision loss?

Advanced diabetic retinopathy can cause permanent vision loss, particularly when complications such as severe bleeding, retinal detachment, or significant damage to the macula occur. Early detection can help reduce these risks.
