Diabetes can have far-reaching effects on the body, & the eyes are often among the most vulnerable. One of the most serious complications is diabetic retinopathy, a condition in which high blood sugar levels slowly damage the tiny blood vessels in the retina — the light-sensitive layer at the back of the eye that allows us to see clearly. Over time, these blood vessels may become weak, swell, leak fluid, or even close entirely, reducing oxygen supply to the retina & gradually affecting vision. In advanced stages, new, abnormal blood vessels may form, which are fragile & prone to bleeding, further increasing the risk of vision loss. Many people may not notice any changes in their eyesight during the early stages, making regular eye examinations & early detection essential. Without timely treatment, diabetic retinopathy can progress silently, ultimately leading to blurred vision, severe vision impairment, or permanent blindness. Fortunately, with proper monitoring, lifestyle management, & modern eye care treatments, it is possible to protect your vision & manage the risks effectively.
Diabetic retinopathy is a complication of diabetes that occurs when long-term high blood sugar levels damage the delicate blood vessels in the retina, the light-sensitive tissue at the back of the eye responsible for capturing images. Initially, the damage may cause the vessels to swell or leak small amounts of fluid, which usually does not produce noticeable symptoms. As the condition advances, some blood vessels may close, reducing blood flow to the retina & depriving it of essential oxygen & nutrients. In response, the eye may form new, abnormal blood vessels, which are fragile & prone to bleeding. This can lead to vision disturbances, floaters, or even severe vision loss if left untreated. Because diabetic retinopathy often develops silently in its early stages, regular eye screenings are essential for all people with diabetes. Early detection allows for timely treatment, which can slow disease progression & protect long-term vision.
Anyone with diabetes — Type 1, Type 2, or gestational — can develop diabetic retinopathy. The risk increases if you:
Even well-controlled diabetes can cause early retinal changes, so routine screening is recommended.
While diabetic retinopathy may not show symptoms initially, advanced stages can cause: • Blurry or fluctuating vision
Immediate evaluation by a retina specialist is recommended if any of these signs appear.
