Diabetes can affect many parts of the body, including the eyes. One of the most important eye conditions linked with diabetes is diabetic retinopathy, a condition that damages the tiny blood vessels of the retina. The retina is the light-sensitive tissue at the back of the eye that allows us to see. Because early diabetic retinopathy may not cause pain or noticeable changes in vision, regular diabetic retinopathy screening in Aizawl is an essential part of protecting sight for people living with diabetes in Mizoram.
A person may feel that their eyesight is normal and still have early retinal changes. Waiting for blurred vision or other symptoms can allow the condition to progress silently. A comprehensive dilated eye examination can detect these changes before daily vision is affected. Early detection gives the eye doctor an opportunity to recommend closer monitoring, improve coordination with the patient’s diabetes physician and begin treatment when necessary.
This guide explains when people with diabetes need an eye test, what happens during screening, which symptoms require urgent attention and how patients in Aizawl can reduce their risk of diabetes-related vision loss.
What is diabetic retinopathy?
Diabetic retinopathy develops when persistently high blood glucose damages the small blood vessels that supply the retina. In the early stage, known as non-proliferative diabetic retinopathy, weakened retinal vessels may leak small amounts of blood or fluid. Some vessels may close, reducing the retina’s blood supply. Swelling can also develop in the macula, the central part of the retina responsible for detailed vision. This is called diabetic macular oedema.
In a more advanced stage, called proliferative diabetic retinopathy, the retina may grow fragile new blood vessels. These abnormal vessels can bleed into the clear gel inside the eye, create scar tissue or pull on the retina. Without timely care, severe bleeding, retinal detachment or glaucoma can threaten vision.
Diabetic retinopathy can affect people with type 1 or type 2 diabetes. The risk generally rises with the duration of diabetes, but changes can occur earlier, particularly when blood glucose, blood pressure or cholesterol levels are not well controlled. Kidney disease, pregnancy and smoking may also increase risk or make existing retinopathy progress more quickly.
Why screening matters even when vision seems normal
One of the most dangerous features of diabetic retinopathy is that the early stages often have no symptoms. Reading, driving and recognising faces may remain comfortable while changes are already developing in the retina. A routine spectacle-power check alone is not enough to rule out diabetic retinopathy because the doctor needs to examine the retina through the pupil.
Screening is not simply a test of how clearly a person can read an eye chart. It is a preventive examination designed to identify retinal changes early, assess their severity and decide when follow-up or treatment is needed. Treatment is generally most effective before major vision loss has occurred.
When should people with type 1 diabetes have an eye examination?
People with type 1 diabetes should generally have an initial comprehensive dilated eye examination within five years of the diagnosis of diabetes. Children and adolescents should follow the timing recommended by their diabetes specialist and eye doctor, as age and the stage of development may influence the schedule.
After the first examination, most patients need regular follow-up. An annual dilated eye examination is a common schedule, although the ophthalmologist may recommend a different interval based on the retinal findings, duration of diabetes and overall medical control.
When should people with type 2 diabetes have an eye examination?
People with type 2 diabetes should arrange a comprehensive dilated eye examination at the time diabetes is diagnosed. Type 2 diabetes can be present for a considerable period before it is detected, so retinal changes may already exist when the diagnosis is made.
Do not wait until vision becomes blurred. Newly diagnosed patients in Aizawl and other parts of Mizoram should include an eye examination in their initial diabetes-care plan. If no retinopathy is found and blood glucose remains well controlled, the eye doctor may sometimes advise an interval of one to two years. However, yearly examinations remain appropriate for many patients, and the schedule must be individualised.
How often is diabetic retinopathy screening needed?
The right screening interval depends on the individual. Factors considered include the type and duration of diabetes, blood glucose control, blood pressure, pregnancy, kidney health, previous retinal findings and whether vision has changed.
- No retinopathy: the eye doctor may recommend yearly review or, for selected well-controlled patients with repeated normal examinations, a one-to-two-year interval.
- Mild diabetic retinopathy: examinations are usually needed at least annually and sometimes sooner.
- Progressing or sight-threatening retinopathy: closer monitoring may be required every few months, along with treatment or referral to a retina specialist.
- Diabetic macular oedema: prompt specialist assessment and an individual treatment plan are important.
Patients should follow the date given by their ophthalmologist rather than assuming that one schedule is suitable for everyone. Missing follow-up appointments can allow silent disease to advance.
Diabetes and pregnancy: when is an eye test required?
Pregnancy can cause diabetic retinopathy to worsen in women who already have type 1 or type 2 diabetes. Women planning pregnancy should ideally have a dilated eye examination before conception. If that has not happened, an examination should usually be arranged during the first trimester, with further monitoring during pregnancy and after delivery as advised by the ophthalmologist.
Gestational diabetes that begins during pregnancy does not usually carry the same retinopathy-screening requirement. However, every patient should discuss their individual situation with the obstetrician, diabetes physician and eye doctor, particularly if the diagnosis or diabetes history is uncertain.
What happens during a diabetic eye screening in Aizawl?
A diabetic eye assessment usually begins with questions about the type and duration of diabetes, medicines, recent blood glucose results, blood pressure, kidney health, pregnancy and any changes in vision. Patients should bring their current spectacles, medication list and relevant medical reports if available.
Vision test
Each eye is tested separately on a vision chart. This measures current visual sharpness but does not by itself exclude retinal disease.
Eye pressure measurement
The pressure inside the eye may be checked because people with diabetes also require attention to other eye conditions, including glaucoma.
Dilated retinal examination
Dilating drops widen the pupils so the ophthalmologist can examine the retina, macula, optic nerve and retinal blood vessels. Vision may remain blurred and sensitive to light for several hours after dilation. Patients may find it useful to bring sunglasses and arrange transport rather than driving until their vision returns to normal.
Retinal photography
Photographs of the back of the eye can document retinal changes and help compare findings over time. Retinal photography is valuable, but it does not always replace a comprehensive in-person examination—especially when images are unclear, symptoms are present or disease is detected.
OCT scan and other tests
Optical coherence tomography, or OCT, produces detailed cross-sectional images of the retina. It can help detect and measure macular swelling. If the doctor needs more information about leaking or blocked blood vessels, additional retinal imaging may be advised.
Symptoms that should not wait for a routine appointment
Early diabetic retinopathy may be symptom-free, but sudden or severe changes require urgent eye care. Contact an eye hospital promptly if you notice:
- a sudden increase in floaters or dark spots;
- flashes of light;
- a dark curtain, shadow or missing area in the field of vision;
- sudden blurred or distorted vision;
- rapid loss of vision in one or both eyes;
- new difficulty seeing at night;
- eye pain or redness together with reduced vision.
These symptoms can occur with bleeding inside the eye, retinal tears, retinal detachment or other urgent conditions. Patients can also read our guides on flashes and floaters in Aizawl and emergency eye symptoms that need immediate treatment.
Can diabetic retinopathy be treated?
Yes. The appropriate treatment depends on the type and severity of retinal disease. Mild changes may only require better diabetes control and closer observation. Diabetic macular oedema or proliferative diabetic retinopathy may require specialist treatment.
Anti-VEGF medicines are injected into the eye under sterile conditions to reduce abnormal vessel growth and retinal swelling. Laser treatment may be used to treat leaking areas or reduce the risk from abnormal new blood vessels. Vitrectomy surgery may be needed when there is persistent bleeding into the eye, traction on the retina or certain forms of retinal detachment.
Not every patient needs a procedure. The essential first step is accurate diagnosis and grading of the retinal changes. An ophthalmologist can explain the findings, discuss benefits and risks, and advise whether monitoring, treatment or referral to a retina specialist is required.
How can people with diabetes protect their eyesight?
Eye screening works best as part of overall diabetes care. The following steps can reduce the risk of developing retinopathy or slow its progression:
- Keep scheduled dilated eye examinations. Do not wait for symptoms.
- Manage blood glucose. Follow the medicine, food and activity plan advised by your diabetes-care team.
- Control blood pressure. High blood pressure can worsen damage to retinal vessels.
- Manage cholesterol and kidney health. Attend regular medical reviews and laboratory tests.
- Avoid smoking. Ask a healthcare professional for help if you need support to stop.
- Report changes quickly. A sudden vision change should be assessed urgently rather than left until the next annual visit.
- Keep records. Note the date and result of each eye examination and the recommended follow-up date.
Preparing for a diabetic eye test at Dr. Nunu Eye Hospital
When arranging a diabetic eye examination in Aizawl, tell the clinic that you have diabetes and mention any recent visual symptoms. Bring a list of medicines, your latest blood glucose or HbA1c report if available, details of blood pressure treatment and any previous retinal records. If the pupils will be dilated, plan for temporary blur and light sensitivity afterward.
A comprehensive eye examination is different from simply obtaining new spectacles. You can learn more about the tests commonly included in a comprehensive eye check-up in Aizawl.
At Dr. Nunu Eye Hospital & Research Centre, patients with diabetes can receive an ophthalmic assessment and guidance on appropriate follow-up. Dr. Lynapawngia Solo can review symptoms and examination findings and advise whether monitoring, additional retinal tests, treatment or specialist referral is appropriate.
Frequently asked questions
I can see clearly. Do I still need diabetic retinopathy screening?
Yes. Early diabetic retinopathy commonly causes no symptoms. Clear vision today does not confirm that the retina is healthy. Screening can detect changes before they begin to interfere with sight.
Is a spectacle-power test enough?
No. A refraction test measures the spectacle prescription, while diabetic retinopathy screening examines the retina. A dilated retinal assessment is an important part of diabetes eye care.
Do I need an eye test every year?
Many people with diabetes need yearly examinations. Some well-controlled patients with repeated normal findings may be advised to return in one to two years. Patients with retinopathy may need more frequent reviews. Follow the personalised schedule given by your ophthalmologist.
Can diabetes cause temporary blurred vision?
Changes in blood glucose can temporarily affect focusing and alter vision. However, blurred vision can also be caused by cataract, diabetic macular oedema or another eye condition. A persistent or sudden change should be examined rather than assumed to be temporary.
Can diabetic retinopathy make a person blind?
Advanced diabetic retinopathy can cause severe vision loss, but screening and timely treatment greatly improve the opportunity to protect sight. Good control of diabetes and other health risks remains important even after eye treatment.
Should both eyes be examined?
Yes. Diabetic retinal changes may differ between the two eyes, so a complete assessment checks each eye separately.
