Diabetic retinopathy Treatment in Singapore: A stage-by-stage guide
Diabetic retinopathy is an eye complication of diabetes that affects the small blood vessels in the retina, the light-sensitive tissue at the back of the eye. In its early stages, it may cause no noticeable symptoms. As the condition progresses, however, it can affect vision and potentially lead to serious sight loss.
The important thing to understand about diabetic retinopathy treatment in Singapore is that there is no single treatment for every person. Management depends largely on the stage of diabetic retinopathy, whether the macula is affected, and how quickly the condition is progressing.
Regular diabetic eye screening in Singapore allows retinal changes to be detected early, sometimes before you notice any change in your vision.
Why treatment depends almost entirely on which stage you are at
Diabetic retinopathy in Singapore is generally classified according to the severity of changes seen in the retinal blood vessels. Broadly, it progresses from non-proliferative diabetic retinopathy (NPDR) to proliferative diabetic retinopathy (PDR).
Some may also develop diabetic macular oedema (DME) at different stages of the disease.
Your eye specialist in Singapore may use a dilated retinal examination, retinal photography and optical coherence tomography (OCT), among other tests, to determine the severity of the condition and whether treatment is required.
Early disease may only require monitoring and better diabetes control. More advanced disease may require laser treatment, eye injections or surgery.
Stage 1 – Mild non-proliferative: Observation and risk factor control
Mild non-proliferative diabetic retinopathy is an early stage of the disease. Small abnormalities develop in the retinal blood vessels, but vision may remain normal.
At this stage, immediate eye treatment is often not required. Instead, regular monitoring and good control of diabetes and other cardiovascular risk factors become particularly important.
What your ophthalmologist is monitoring and why
During follow-up appointments, your ophthalmologist will look for signs that the retinopathy is progressing.
The examination may assess changes such as retinal haemorrhages, abnormal blood vessels and fluid accumulation. OCT imaging may also be used to detect swelling in the macula.
The frequency of follow-up appointments depends on the severity of the retinal changes and your overall health.
Regular diabetic eye screening in Singapore remains important even when your vision appears normal because diabetic retinal changes can develop without obvious symptoms.
The role of glucose, blood pressure and cholesterol control
Managing diabetes is an important part of protecting your eyes.
Good blood glucose control can reduce the risk of diabetic retinopathy developing or progressing. Blood pressure and cholesterol should also be appropriately managed with your treating doctor.
Eye treatment addresses the retinal complications of diabetes, but it does not replace good overall diabetes management.
Stage 2 – Moderate to severe NPDR: Closer monitoring and possible laser
As diabetic retinopathy progresses from moderate to severe NPDR, more retinal blood vessels become affected.
Those at this stage generally require closer follow-up because there is a greater risk of progression to proliferative diabetic retinopathy.
Treatment is individualised. Depending on the retinal findings and whether diabetic macular oedema is present, your eye specialist in Singapore may recommend observation, intravitreal injections, laser treatment or a combination of approaches.
Not everyone with moderate or severe NPDR requires immediate laser treatment. The decision depends on the specific retinal findings and risk of progression.
Stage 3: Proliferative diabetic retinopathy: When treatment becomes urgent
Proliferative diabetic retinopathy is an advanced stage in which abnormal new blood vessels develop on the retina or optic disc.
These vessels are fragile and may bleed into the vitreous, the gel-like substance inside the eye. Scar tissue can also develop and, in advanced cases, pull on the retina.
Treatment at this stage is important to reduce the risk of severe vision loss.
Pan-retinal photocoagulation (PRP) laser – What it is and what to expect
Pan-retinal photocoagulation, or PRP, is an established laser treatment for proliferative diabetic retinopathy.
During PRP, multiple laser spots are applied to selected areas of the peripheral retina. The purpose is to reduce the stimulus that drives the growth of abnormal new blood vessels.
Treatment may require more than one session depending on the condition of the eye.
PRP is intended primarily to preserve vision and reduce the risk of serious complications rather than improve vision that has already been permanently lost.
Intravitreal injections for diabetic retinopathy
Intravitreal injections deliver medication directly into the eye. Anti-VEGF medications can reduce signals that encourage abnormal blood vessel growth and leakage.
Depending on the condition, injections may be used to manage proliferative diabetic retinopathy, diabetic macular oedema, or both.
Your ophthalmologist will determine whether injections, PRP laser or a combination of treatments is appropriate.
Diabetic macular oedema: The complication that threatens central vision
Diabetic macular oedema occurs when damaged retinal blood vessels leak fluid into the macula, the central part of the retina responsible for detailed vision.
Unlike the general staging of diabetic retinopathy, DME can occur at different stages of the disease.
People may notice blurred or distorted central vision, although early changes may sometimes be detected during an eye examination before significant symptoms develop.
Anti-VEGF injections: What the treatment course looks like
Anti-VEGF injections are commonly used to treat diabetic macular oedema.
Before the injection, the eye is numbed and cleaned to reduce discomfort and infection risk. The medication is then administered into the eye.
People generally require follow-up examinations and OCT scans to assess whether the macular swelling is improving.
How many injections are typically needed
There is no fixed number of injections that applies to every person.
Some initially require a series of injections at relatively short intervals, followed by less frequent treatment as the condition stabilises. Others may need ongoing treatment.
The number and frequency of injections depend on factors such as OCT findings, visual response, severity of swelling and the medication being used.
Your eye specialist in Singapore should discuss the expected treatment schedule based on your individual condition.
Advanced disease: Vitrectomy and when surgery is necessary
In advanced diabetic retinopathy in Singapore, surgery may sometimes be required.
Vitrectomy is an operation that removes the vitreous gel from inside the eye. It may be considered when there is persistent or significant vitreous bleeding, retinal traction, or certain forms of retinal detachment caused by advanced diabetic eye disease.
Whether surgery is necessary depends on the extent of retinal damage and other findings inside the eye.
What does diabetic retinopathy treatment cost in Singapore
The cost of diabetic retinopathy treatment in Singapore varies considerably because treatment can range from routine monitoring to laser procedures, repeated intravitreal injections or vitrectomy surgery.
Costs may also depend on the type of medication used, number of injections required, investigations performed, treatment setting and whether one or both eyes require treatment.
Insurance and MediSave eligibility may also differ depending on the procedure and individual circumstances. You should request a personalised financial estimate after assessment rather than relying on a single general price for diabetic retinopathy treatment.
Schedule a diabetic eye assessment at Eye Max Centre
If you have diabetes, do not wait until your eyesight becomes noticeably blurred before having your retina examined.
Regular diabetic eye screening in Singapore can identify retinal changes at an earlier stage, when monitoring or treatment may help reduce the risk of progression.
At Eye Max Centre, a detailed diabetic eye assessment can determine whether there are signs of diabetic retinopathy, macular swelling or other diabetes-related eye complications.
If treatment is necessary, an eye specialist in Singapore can explain the severity of your condition and whether monitoring, laser treatment, intravitreal injections or surgery may be appropriate.
Early detection and appropriate follow-up remain important parts of protecting your vision when living with diabetes.
