Diabetic retinopathy is an eye condition caused by long-term high blood sugar levels damaging the tiny blood vessels in the retina. Over time, these weakened vessels may leak, swell or close off, leading to vision problems. If untreated, diabetic retinopathy can progress to proliferative diabetic retinopathy, where abnormal new vessels form and significantly increase the risk of vision loss.
This condition often progresses silently in the early stages, which is why regular eye screening is crucial for individuals living with diabetes mellitus.
Symptoms may develop gradually and may not appear until the disease has progressed.
If you notice vision changes and you have diabetes, seek an eye assessment promptly.
Diabetic retinopathy occurs when prolonged high blood glucose damages retinal blood vessels.
Diagnosis of diabetic retinopathy focuses on detecting early damage to the retinal blood vessels and assessing how advanced the condition has become. A detailed eye examination allows specialists to evaluate swelling, bleeding and abnormal vessel growth long before vision loss becomes obvious.
Diabetic retinopathy progresses in predictable stages based on the severity of blood vessel damage and abnormal new vessel formation. Recognising the stage of disease helps specialists determine the urgency of treatment and long-term monitoring needs.
This is the early stage, where retinal blood vessels become weakened and begin to leak fluid or blood.
This is the advanced and most sight-threatening stage, marked by the growth of fragile abnormal blood vessels (neovascularisation). These new vessels bleed easily, causing sudden floaters, dark vision patches or rapid vision loss.
Scar tissue formation may pull the retina away from the back of the eye, leading to retinal detachment. Increased eye pressure and neovascular glaucoma may also develop. PDR requires urgent treatment to prevent permanent blindness.
Understanding the stages of diabetic retinopathy allows specialists to plan laser therapy, injections or surgery at the right time to preserve long-term vision.
Treatment depends on severity and the presence of complications such as macular oedema.

Without timely intervention, diabetic retinopathy may lead to:
Early detection and consistent eye screening reduce these risks significantly.
With proper management, many people maintain good vision for years.
Diabetic retinopathy is a common eye complication caused by long-term high blood sugar, damaging small retinal blood vessels. It often develops silently, with many patients unaware of the condition until vision changes appear. The two main stages are non-proliferative diabetic retinopathy and proliferative diabetic retinopathy.Â
Non-proliferative stages involve vessel leakage and swelling, while proliferative disease is marked by abnormal new vessel growth that can bleed. Without proper control, diabetic retinopathy in Singapore can progress to severe vision loss or blindness. Understanding the type and stage helps determine how urgently treatment is needed.
Management of diabetic retinopathy begins with a referral to an eye specialist for a detailed retinal examination. After diagnosis, treatment may include laser therapy, injections to reduce abnormal vessel growth or surgery in advanced cases. Blood sugar, blood pressure and cholesterol control are essential parts of treatment alongside eye procedures.Â
Patients are advised to attend regular eye screenings even when vision feels normal. Follow-up visits are used to assess disease progression and adjust treatment plans. With structured care, many individuals with diabetic retinopathy can preserve useful vision long term.
You should seek medical attention if you notice blurred vision, dark floaters, difficulty seeing at night or sudden vision loss. These symptoms may indicate advancing diabetic retinopathy and require urgent evaluation.Â
Eye problems may worsen rapidly if blood sugar levels remain poorly controlled. Delaying care increases the risk of permanent retinal damage and vision impairment. Even without symptoms, individuals with diabetic retinopathy in Singapore should undergo routine eye screening at least once a year. Early detection allows treatment to begin before irreversible vision loss occurs.
You do not have to manage diabetic retinopathy on your own. A qualified eye specialist can assess your retina, explain your condition clearly and recommend treatment options tailored to your needs.
