Diabetes Affects Your Eyes in Ways You May Not Feel Until It Is Too Late to Prevent

Diabetic eye disease is one of the leading causes of blindness among working-age adults in the United States, and one of the most preventable when identified early. The problem is that it develops without symptoms. By the time a patient notices a change in vision, meaningful retinal damage has often already occurred.

Bergen Optometry in Hackensack, NJ provides comprehensive diabetic eye exams for patients with Type 1 and Type 2 diabetes throughout Bergen County and Northern New Jersey. Annual dilated examinations are not optional for diabetic patients. They are the clinical standard that makes early intervention possible.

How Diabetes Damages the Eyes

Chronically elevated blood sugar damages blood vessels throughout the body. In the eye, this affects the delicate network of vessels supplying the retina, the light-sensitive tissue at the back of the eye responsible for all visual processing.

Diabetic Retinopathy

Diabetic retinopathy is the most common diabetic eye complication. It develops in two stages:

  • Non-proliferative diabetic retinopathy (NPDR): The early stage, in which retinal blood vessels weaken, swell, and may begin to leak. There are typically no visual symptoms at this stage, but the damage is detectable and documented during a dilated examination.
  • Proliferative diabetic retinopathy (PDR): The advanced stage, in which new, fragile blood vessels grow abnormally on the retinal surface and into the vitreous. These vessels bleed easily and can cause severe vision loss, vitreous hemorrhage, or retinal detachment.

Diabetic Macular Edema

Fluid can accumulate within the macula (the central portion of the retina responsible for detail vision), causing it to swell. Diabetic macular edema (DME) is the most frequent cause of vision loss among patients with diabetic retinopathy and can develop at any stage of the disease.

Elevated Risk for Glaucoma and Cataracts

Patients with diabetes are approximately twice as likely to develop glaucoma and tend to develop cataracts at an earlier age than the general population. Both conditions are evaluated as part of every comprehensive diabetic eye exam at Bergen Optometry.

What a Diabetic Eye Exam Includes

A diabetic eye exam is more clinically thorough than a standard vision check. At Bergen Optometry, your exam includes:

  • Dilated fundus examination: The most important component. Dilating the pupils provides a wide, clear view of the retina, macula, and optic nerve, allowing us to identify diabetic changes at their earliest detectable stage.
  • Retinal imaging: High-resolution photographs document your retinal baseline and allow direct comparison at subsequent visits to track progression or improvement.
  • Intraocular pressure measurement: Routine glaucoma screening.
  • Visual acuity assessment: To measure any functional impact on vision.
  • Systemic review: We ask about your current A1C, blood pressure management, and any recent changes to your diabetes treatment, as these directly influence your ocular risk profile.

How Often Diabetic Patients Should Have Eye Exams

The American Diabetes Association and the American Optometric Association both recommend annual dilated eye exams for all patients with diabetes. If retinopathy is already present, monitoring frequency increases, typically to every three to six months depending on severity.

For newly diagnosed Type 2 diabetes, an initial dilated exam should occur as soon as possible after diagnosis. For Type 1 diabetes, the first exam is recommended within five years of diagnosis and annually thereafter.

When Diabetic Eye Disease Is Found

When our doctors identify signs of diabetic retinopathy or macular edema, we explain the findings clearly: what stage the disease is at, what the clinical options are, and what the evidence supports. For early-stage disease, improved glycemic control and close monitoring are often the first priority. For more advanced disease, we coordinate referral to a retinal specialist for laser therapy, anti-VEGF injections, or surgical intervention.

We communicate directly with your primary care physician or endocrinologist. Your care team stays aligned, and you are not left to navigate between specialists on your own.

Schedule Your Diabetic Eye Exam

Diabetic eye disease is most treatable when found before it causes symptoms. A dilated exam once a year is the most reliable way to stay ahead of it.
