Consultant retina assessment for diabetes-related eye disease, macular conditions, retinal vascular disease, tears, haemorrhage and premature infants—supported by imaging, laser and injection-based care when indicated.
The retina is a thin layer of light-sensitive nerve tissue lining the inside of the back of the eye. It changes focused light into electrical signals that travel through the optic nerve to the brain, where they are interpreted as vision.
The macula is the specialised central part of the retina used for reading, recognising faces, colour vision and fine detail. The peripheral retina supports side vision and helps detect movement. Damage in either area can matter, but macular disease is especially likely to affect central visual tasks.
A retinal tear, detachment, vascular blockage or severe inflammation can change vision suddenly without causing eye pain. If symptoms are new, sudden or rapidly worsening, seek prompt eye assessment or an appropriate emergency service.
Dilated examination and imaging help identify whether the problem is leakage, blocked circulation, abnormal vessels, a tear, bleeding, traction or degeneration. Treatment is chosen for the underlying cause rather than the symptom alone.
Diabetes can damage and close the retina’s smallest blood vessels. Early disease may have no symptoms; later stages can cause leakage, macular swelling, abnormal new vessels, bleeding or traction on the retina.
Care may include closer monitoring, control of diabetes and blood pressure, OCT imaging, intravitreal injections, retinal laser or vitreoretinal surgical referral depending on the stage.
Diabetic macular oedema occurs when damaged retinal vessels leak fluid into the macula—the area responsible for detailed central vision. It may blur or distort reading and face recognition.
OCT helps measure the swelling and monitor response. Anti-VEGF injections are commonly considered, while laser or other treatment may be appropriate in selected situations.
AMD affects the macula and can blur, distort or remove parts of central vision while side vision is often retained. Dry AMD usually progresses more slowly; wet AMD involves abnormal leaking or bleeding vessels and needs timely assessment.
Monitoring, home-vision advice and risk reduction may be used for dry AMD. AREDS2 supplements help only certain stages and should be recommended after examination. Wet AMD is commonly treated with repeated anti-VEGF injections.
A blocked retinal vein can cause sudden, usually painless blur or loss of vision. Branch occlusion affects part of the retinal circulation; central occlusion affects the main retinal vein and can be more extensive.
OCT and retinal examination assess macular oedema and complications. Treatment may include anti-VEGF injections, selected laser treatment and attention to blood pressure, diabetes, glaucoma or other vascular risks.
A retinal tear may allow fluid to pass underneath the retina and cause a detachment. Sudden flashes, many new floaters or a curtain-like shadow can be warning symptoms even when there is no pain.
Suitable tears may be sealed with laser retinopexy before detachment develops. A retinal detachment usually needs urgent evaluation and often vitreoretinal surgery rather than routine clinic treatment.
Blood leaking into the vitreous can cause spots, cobwebs, haze or marked painless loss of vision. Common causes include proliferative diabetic retinopathy, a retinal tear or other abnormal retinal vessels.
The priority is to identify the cause and check whether the retina is attached. Ultrasound may be needed when blood blocks the view; treatment can include observation, laser, injections or surgical referral.
ROP is abnormal retinal blood-vessel development in premature or very low-birth-weight babies. Parents cannot see its early stages, so examinations must follow the neonatal team’s timing even when the baby appears well.
Many mild cases are monitored, while higher-risk disease may need laser, anti-VEGF treatment or surgery. Follow-up timing is critical because ROP can progress quickly and may recur after treatment.
Diabetic retinopathy can be present while vision still feels normal. A comprehensive dilated examination can identify microaneurysms, bleeding, leakage, reduced circulation or abnormal new vessels before the patient notices a major change.
Most people with diabetes need a dilated eye examination at least annually, but the interval should be personalised. Existing retinopathy, pregnancy, rapid changes in diabetes control or other eye findings may require closer review.
Not every patient needs every test. The retina specialist selects imaging based on the suspected condition and whether the result is likely to change monitoring or treatment.
Dilating drops widen the pupil so the macula, optic disc and peripheral retina can be examined with slit-lamp lenses and indirect ophthalmoscopy. Vision may remain blurred and light-sensitive for several hours.
OCT uses reflected light to create cross-sectional images of retinal layers. It helps detect and measure macular oedema, fluid, traction and structural changes, and is often repeated to monitor treatment response.
FFA photographs retinal circulation after fluorescent dye is injected into a vein. It can map leakage, blocked circulation and abnormal vessels when the result is likely to change diagnosis or treatment planning.
Fundus photographs document visible retinal findings over time. If cataract or vitreous haemorrhage blocks the view, an ocular ultrasound may help assess the retina and vitreous behind the opacity.
Retinal treatment often depends on repeated measurements and response over time. The expected benefit, number of visits, possible risks and signs requiring urgent contact should be discussed before a procedure.
Not every retinal finding needs immediate procedure-based treatment. Scheduled imaging and examinations may be combined with diabetes, blood-pressure, lipid and smoking-risk management through the patient’s physicians.
Anti-VEGF medicines and, in selected conditions, steroid medicines are injected into the vitreous after numbing and antiseptic preparation. Many retinal diseases need a planned series rather than a single injection.
Laser can seal selected retinal tears, treat areas of abnormal or non-perfused retina and reduce the risk from proliferative diabetic retinopathy. The purpose and possible effects differ by laser pattern.
Retinal detachment, non-clearing vitreous haemorrhage, traction or other surgical disease may need vitrectomy or another operation. The retina clinic can assess urgency and coordinate referral when surgery is indicated.
Availability and suitability of injections, laser and surgery depend on the diagnosis, examination, medicine selected, procedure setting and specialist recommendation. Some surgical conditions require referral to a vitreoretinal surgical centre.
Babies born very prematurely or at very low birth weight can develop abnormal retinal vessels without any outward sign. The neonatal or paediatric team determines whether screening is required and when the first examination should occur.
Follow-up dates must be kept precisely because the retina may change quickly. Mild disease may only need observation, while higher-risk ROP can require laser, anti-VEGF treatment or surgery under an appropriately trained team.
Symptoms, timing, medical conditions, medicines and prior retina treatment are reviewed before vision and eye pressure are checked.
Drops widen the pupil for a detailed retina examination. OCT, photography, FFA or ultrasound is arranged only when indicated.
The specialist explains the diagnosis, urgency, treatment choices, follow-up interval and whether laser, injection or surgical referral is appropriate.
Dilation can blur near vision and increase light sensitivity for several hours. Consider bringing sunglasses and avoid driving until vision is safe.
Outpatient OCT or FFA may not be covered even when laser, injections or surgery are eligible. Some policies require pre-authorisation, a confirmed diagnosis, previous treatment records and limits linked to the medicine or procedure package.
JEWCC can help prepare available clinical documents, but approval and reimbursement decisions remain with the insurer or TPA.
The retina clinic is held at the Nallasopara East eye centre every Thursday. Call before travelling to confirm the appointment time, planned dilation and whether old scans or reports should be brought.
Jaypuriya Eye Care Centre
The consulting retina specialist is available every Thursday at the JEWCC Nallasopara East centre. Call before travelling to confirm the current appointment time and whether dilation or a specific test is likely to be needed.
No. Diabetic retinopathy and several other retinal conditions may begin without noticeable symptoms. A dilated retinal examination can detect changes before vision is affected.
Bring recent diabetes reports if available, a medicine list, current spectacles and previous eye scans or injection records. Most people with diabetes need a dilated retinal examination at least annually, but the interval can be shorter during pregnancy or when retinopathy is already present.
OCT is a non-contact light scan that shows cross-sections of retinal layers and fluid. FFA uses fluorescent dye injected into a vein and a sequence of retinal photographs to map circulation, leakage and blocked areas. The specialist chooses the test based on the clinical question.
Often not. Anti-VEGF treatment for diabetic macular oedema, wet AMD or vein-occlusion-related swelling commonly requires a planned loading phase and continued monitoring. The number and spacing of injections depend on response and the condition being treated.
A suitable retinal tear may be treated with laser retinopexy. If the retina has detached, an operation is often required and timing can be urgent. The correct treatment depends on the tear, symptoms, vitreous traction and whether fluid has passed under the retina.
Coverage differs by policy. Outpatient consultations and scans may be excluded even when a procedure is covered. Injections, laser or surgery may require pre-authorisation, diagnosis documents and limits for the medicine or package. The insurer or TPA makes the final decision.
