San Antonio eye care
Diabetic eye disease in San Antonio, TX
Diabetes can damage the small blood vessels of the retina. Yearly dilated exams catch changes early, when treatment works best.
What is diabetic eye disease?
Diabetic retinopathy happens when high blood sugar weakens the tiny blood vessels in the retina. They can leak fluid and blood, or abnormal new vessels can grow. When fluid collects in the macula, the center of the retina, it is called diabetic macular edema.
Diabetes also raises the risk of cataracts and glaucoma, so people with diabetes benefit from regular exams with an eye surgeon who treats all three. South Texas has high rates of diabetes, which makes screening especially important here.
Sudden vision loss, a sudden shower of floaters, or a curtain over your vision needs a same-day exam.

Questions
Common questions
How often should I have an eye exam with diabetes?
At least once a year, or more often if changes are found. Pregnancy calls for closer monitoring.
Can diabetic retinopathy be reversed?
Early damage can stabilize and swelling can improve with treatment. Catching it early is the best protection.
