Evaluations in San Pedro Garza García (Río de la Plata 113, Col. Del Valle), minutes from Monterrey.

What is diabetic retinopathy?
Diabetic retinopathy is a complication of diabetes that damages the blood vessels of the retina. In its early stages it has no symptoms, so everyone with diabetes should have a retina exam even if their vision is good.
Dr. Alan Treviño, ophthalmologist and retina specialist with subspecialty training in retina and vitreous, diagnoses and treats diabetic retinopathy with laser, intravitreal injections and retina surgery at his office in San Pedro Garza García (Río de la Plata 113, Col. Del Valle), just minutes from Monterrey.
How does a person with diabetic retinopathy see?

Symptoms
Blurry vision
Or vision that changes during the day.
Spots or floaters
Dark spots that float.
Distorted vision
Straight lines look wavy.
Sudden vision loss
Seek care immediately.
Which stage is it?
Non-proliferative
Retinal vessels weaken and may leak fluid or blood. It can progress if not controlled.
Proliferative
Abnormal, fragile vessels grow and can bleed inside the eye or pull on the retina and detach it.
Diabetic macular edema
Fluid buildup in the macula, the center of vision. It is the most common cause of vision loss from diabetes.

Control of blood sugar, blood pressure and cholesterol with your physician.

Frequently asked questions
Can diabetic retinopathy be cured?
Damage that has already occurred cannot be fully reversed, but timely treatment can stop its progression and, in many cases, improve vision, especially when there is macular edema.
How often should a person with diabetes have a retina exam?
At least once a year, even if your vision is good. If you already have retinopathy, are pregnant or your blood sugar is hard to control, exams should be more frequent, as your retina specialist recommends.
Which is better, laser or injections?
It depends on the stage of retinopathy and whether there is macular edema. They are often combined. After your evaluation and tests we explain which treatment is right for you.
How much does diabetic retinopathy treatment cost?
It depends on the stage and the treatment you need (laser, intravitreal injections or surgery) and on the materials used. At your visit we review your tests and give you a personalized quote. We also guide you if you have private health insurance.
Can diabetes make me blind?
Yes, if retinopathy is not detected and treated. The good news is that with regular exams and timely treatment, most cases of blindness from diabetes can be prevented.
