Diabetic retinopathy
Diabetes can damage your retina before your vision changes. I diagnose and treat diabetic retinopathy with laser, anti-VEGF injections and surgery.

Early diagnosis, personalized follow-up and modern treatment to protect your vision if you have diabetes
If you have diabetes and haven’t had an eye exam in the past year, or you’ve already noticed changes in your vision, schedule your visit with me. I will examine your retina thoroughly and tell you whether you need treatment, follow-up, or just regular monitoring.
What is diabetic retinopathy?
Diabetic retinopathy is a vision complication that occurs when high blood sugar damages the blood vessels in the retina, the light-sensitive tissue inside the eye.
This damage can progress silently, and if it isn’t caught in time, it can lead to significant vision loss.
Diabetes doesn’t only affect your blood glucose. It can affect your eyes too, and this clinical picture is commonly known as diabetic eye disease.
What are the features of diabetic retinopathy?
Retinopathy develops slowly and doesn’t always cause symptoms at first. Its main features are:
- Progressive damage to the retina’s capillaries
- Fluid buildup (edema) or bleeding inside the eye
- Abnormal new blood vessel growth in advanced stages
- Vision changes, especially when the macula is inflamed
As it advances, it’s classified into different grades, including non-proliferative diabetic retinopathy (mild to moderate) and proliferative diabetic retinopathy, which is more severe.
What are the symptoms of diabetic eye disease?
Symptoms can vary depending on the degree of damage, but the most common are:
- Blurred or distorted vision
- Trouble reading or focusing
- Dark areas or blind spots in your field of vision
- Vision that fluctuates
- Floaters or flashes of light
- Sudden vision loss (in cases of vitreous hemorrhage)
It’s important to point out that diabetic retinopathy often causes no symptoms until the damage is already advanced, which is why I recommend regular exams even if your vision seems fine.
What is proliferative diabetic retinopathy?
Proliferative diabetic retinopathy is the most advanced and dangerous form of the disease.
At this stage, the retina responds to chronic damage by growing new, abnormal blood vessels that tend to bleed or cause retinal detachment. It can cause severe vision loss or even blindness if it isn’t treated.
That’s why catching it before it reaches this stage is critical.
How is diabetic retinopathy diagnosed?
To diagnose this condition, I perform a complete in-office evaluation that includes:
- Dilated fundus exam
- Optical coherence tomography (OCT) to measure macular edema
- Fluorescein angiography to check retinal circulation
- Evaluation with a slit lamp and specialized lenses
I also review your history, type of diabetes, how long you’ve had it, and your general blood sugar control. Every study is done right here in the office, with no need to visit another center.
Is diabetic retinopathy reversible?
In its early stages, the damage can be controlled and stabilized, but it isn’t fully reversible.
In advanced stages, the goal shifts to preventing further damage, and in some cases improving vision if treatment starts in time.
That’s why I insist on early detection: the sooner I act, the better my chances of protecting your vision.
What is the treatment for diabetic retinopathy?
Treatment depends on how advanced the disease is. The options I offer include:
1. General medical control
- Controlling glucose levels, blood pressure and lipids is essential
- Without good systemic control, no eye treatment will be enough on its own
2. Intraocular injections
- Anti-angiogenic drugs (anti-VEGF) that stop abnormal vessel growth
- Useful in diabetic macular edema and proliferative stages
3. Laser (retinal photocoagulation)
- Seals damaged vessels and prevents bleeding
- A precise, outpatient technique, very effective in moderate or proliferative cases
4. Vitreoretinal surgery
- For cases with severe intraocular bleeding or retinal detachment
- A specialized procedure I perform in coordination with advanced surgical retina care
Are there eye drops for diabetic retinopathy?
Eye drops aren’t a primary treatment for diabetic retinopathy, but they can support care in certain situations:
Anti-inflammatory drops for mild edema.
Lubricating drops to improve comfort.
In early stages, they can complement medical management.
Still, the main treatment remains injections, laser or systemic control.
What does current evidence say about diabetic retinopathy?
Here is what the evidence shows today:
- Early metabolic control is more effective than treating the damage once it appears
- Intraocular injections significantly improve vision when given in time
- Combining laser with medication produces more lasting results
- Advances in imaging let us detect retinal damage well before symptoms appear
In short: the earlier diabetic retinopathy is detected and treated, the better the long-term visual outcome.
Who do I treat?
I see patients with type 1 or type 2 diabetes, at any stage of their visual condition. My office is at Hospital Aranda de la Parra Puerto Interior, 20 minutes from León and minutes from Bajío International Airport (BJX). I welcome patients from the entire Bajío region, all of Mexico, the United States, Canada and Latin America.
I am fluent in English, so the whole consultation can be in English, and I offer personalized care, clear diagnoses and practical solutions to protect your vision if you live with diabetes.
