When to see an eye doctor
Proper treatment of diabetes is the best way to prevent vision loss. If you have diabetes, a yearly dilated eye exam with an eye care professional is recommended, even if your vision seems fine.
Developing diabetes when pregnant, called gestational diabetes, or having diabetes before becoming pregnant can increase your risk of diabetic retinopathy. If you’re pregnant, your healthcare professional might recommend additional eye exams throughout your pregnancy.
Contact a medical professional right away if your vision changes suddenly or becomes blurry, spotty or hazy.
