If you or a loved one lives with Type 1 or Type 2 diabetes, safeguarding your vision should be a top healthcare priority. Diabetes directly impacts the microvascular system throughout the body—and the tiny, fragile blood vessels in your retina are especially susceptible to high blood glucose levels.
At Kona Eye Care, Dr. Khoa Nguyen, OD emphasizes regular, proactive diabetic eye monitoring in close partnership with local Hawai‘i Island primary care physicians and endocrinologists.
What Is Diabetic Retinopathy?
Diabetic retinopathy occurs when chronically elevated blood sugar damages the delicate walls of capillaries supplying the retina (the light-sensitive tissue lining the back of your eye). The condition typically progresses through two distinct stages:
- Non-Proliferative Diabetic Retinopathy (NPDR): In this early stage, capillary walls weaken and develop microaneurysms. Fluid, lipids, and small amounts of blood begin to leak into the retinal tissue, which can lead to swelling in the central macula (Diabetic Macular Edema, or DME).
- Proliferative Diabetic Retinopathy (PDR): As more blood vessels become blocked, the deprived retina attempts to grow new, abnormal vessels (neovascularization). These fragile new vessels frequently bleed into the clear vitreous gel of the eye, causing severe sudden blurriness or dark floaters, and can cause tractional retinal detachments.
The Silent Nature of Early Retinal Changes
The most dangerous characteristic of diabetic eye disease is that in its earliest and most treatable stages, there are almost never any symptoms. You cannot feel high blood sugar damaging your retina, and your central vision may remain completely sharp (20/20) even while active microvascular leakage is occurring in the peripheral retina.
By the time a patient notices dark spots, distortion, or significant vision loss, substantial tissue damage has often already occurred.
What Happens During a Diabetic Eye Examination?
A comprehensive diabetic eye exam goes significantly beyond checking your eyeglass prescription. Key diagnostic steps include:
- Dilation of the Pupils: Special eye drops widen your pupils so Dr. Nguyen can thoroughly inspect the entire peripheral retina, macula, and optic nerve head.
- Digital Retinal Imaging: Capturing high-resolution photographic documentation of your retinal landscape to detect subtle hemorrhages and track microvascular changes year after year.
- Detailed Physician Reporting: Following your examination, Kona Eye Care sends a formal diabetic eye examination report directly to your primary care doctor to ensure your overall diabetes management plan is synchronized.
Protecting Your Vision for the Future
Maintaining tight glycemic control (HbA1c levels), keeping blood pressure and cholesterol within recommended ranges, staying physically active, and attending your annual dilated eye exam can reduce your risk of severe diabetic vision loss by up to 95%.
If you have diabetes and haven’t had a dilated retinal examination within the past 12 months, please don’t wait. Schedule your diabetic eye exam at Kona Eye Care today.
