Diabetic Retinopathy: Symptoms, Treatment & Cost in Turkey
Talk to our team
In this article 9 sections
Diabetic retinopathy is one of the most common complications of diabetes — and one of the leading causes of preventable blindness. The good news is that with early detection and the right treatment, most people can protect their vision and stop the disease progressing.
This complete guide explains what diabetic retinopathy is, its stages and symptoms, the treatments available (laser, anti-VEGF injections and surgery), and what treatment costs in Turkey compared with the UK and USA — where accredited clinics offer the same care for 60–80% less.
Quick summary: Diabetic retinopathy damages the retina's blood vessels due to high blood sugar. Treatments — blood-sugar control, anti-VEGF injections, laser, and vitrectomy for advanced cases — aim to stop progression and preserve vision. In Turkey, treatment sessions typically cost €275–€920 (versus €3,500–€5,000 in the West), with high success rates at accredited clinics. Early treatment gives the best outcome.
What is diabetic retinopathy? (the stages)
Diabetic retinopathy is damage to the blood vessels of the retina — the light-sensitive layer at the back of the eye — caused by persistently high blood sugar. Over time, high glucose weakens these tiny vessels, making them leak or become blocked, and in advanced cases the eye grows fragile new vessels that can bleed. It develops in two main stages:
- NPDR (non-proliferative diabetic retinopathy) — the earlier stage, graded mild, moderate or severe. The retinal vessels develop microaneurysms, small bleeds and leakage, but no new vessels yet. Often no symptoms.
- PDR (proliferative diabetic retinopathy) — the advanced stage, where the retina grows abnormal new blood vessels (neovascularisation). These are fragile and can bleed into the eye or pull on the retina, risking serious vision loss.
At any stage, diabetic macular edema (DME) — swelling of the central retina — can develop and is a common cause of vision loss in diabetes.
Symptoms & warning signs
The dangerous truth about diabetic retinopathy is that in its early stages it usually causes no symptoms at all — the damage builds silently. As it progresses, you may notice blurred or fluctuating vision, floaters (dark spots or strands), dark or empty areas in your vision, difficulty seeing at night, or colours appearing washed out.
In advanced cases, bleeding in the eye can cause sudden, significant vision loss. Because early damage is invisible, waiting for symptoms is not a safe strategy — regular screening is essential for anyone with diabetes.
How it's diagnosed
Diabetic retinopathy is diagnosed through a dilated retinal examination and advanced imaging. Optical coherence tomography (OCT) produces detailed cross-sections of the retina to detect swelling, and fluorescein angiography maps the blood flow to pinpoint leaking or blocked vessels. Together these show your ophthalmologist exactly where the damage is and which treatment is most appropriate for your stage.
Treatment options
There's no cure for diabetic retinopathy, but treatment can effectively stop or slow it and preserve your vision — and the earlier it starts, the better it works. The right approach depends on your stage and whether macular edema is present:
- Blood sugar, blood pressure & cholesterol control: the foundation, especially in early NPDR — good control can slow or halt progression.
- Anti-VEGF injections (such as Avastin, Lucentis or Eylea): the standard of care for diabetic macular edema and early proliferative disease. Injected into the eye, they reduce fluid leakage, swelling and abnormal vessel growth. They're usually repeated every 4–12 weeks depending on response.
- Laser therapy: focal/grid laser seals specific leaking vessels in the macula, while panretinal photocoagulation (PRP) is used in advanced (proliferative) disease to shrink abnormal vessels across the retina. It's a quick outpatient procedure (15–30 minutes) under local anaesthetic. Importantly, laser prevents further loss rather than restoring vision already lost.
- Vitrectomy surgery: for advanced cases with vitreous bleeding or scar tissue pulling on the retina, a vitrectomy removes the vitreous gel and repairs the retina to restore or protect vision.
Treatment cost: Turkey vs UK & USA
Diabetic retinopathy often needs ongoing treatment — repeated injections or multiple laser sessions — so cost matters a great deal over time. This is a major reason patients look to Turkey:
| Treatment | 🇹🇷 Turkey | 🇬🇧🇺🇸 UK / USA / West |
|---|---|---|
| Laser (per session) | $300–$1,000 | $744–$2,396 |
| Anti-VEGF injection | $200–$1,000 | $506–$2,000 |
| Vitrectomy (per eye) | $2,500–$5,000 | $8,000–$14,000 |
| Per session (general) | €275–€920 | €3,500–€5,000 |
Across the board, treatment in Turkey costs roughly 60–80% less than in the UK, USA or Australia — the same medications (Avastin, Lucentis, Eylea), the same laser and surgical techniques, at a fraction of the price. The exact cost depends on your stage, which treatment you need, and how many sessions. Because diabetic retinopathy can require ongoing care, these savings add up substantially over time. Always get a written treatment plan and quote after an assessment.
Why Turkey for diabetic retinopathy treatment?
Turkey has become a popular destination for ophthalmology, and diabetic retinopathy care is no exception. Beyond the 60–80% saving, patients choose Turkey for its experienced ophthalmologists and vitreoretinal surgeons, internationally accredited clinics with modern diagnostic technology (OCT and fluorescein angiography) and surgical equipment, and the full range of treatments — laser, injections and vitrectomy — all in one place.
Major centres include Istanbul, Antalya, Izmir and Ankara. For anyone facing repeated, costly treatment at home, accessing specialist care at a fraction of the price can be genuinely life-changing — as long as you choose an accredited clinic and a qualified specialist.

Let's be honest and clear: diabetic retinopathy can't be cured, and laser treatment doesn't restore vision that's already been lost. But that's not the whole story — with early diagnosis and timely treatment, most people can stop the disease progressing and keep the vision they have, avoiding severe loss or blindness.
Success rates for treatment are high (up to around 95% for halting progression in appropriate cases). The single biggest factor in a good outcome is catching it early — which comes back to regular screening and acting promptly on any change in your vision. Managing your diabetes well remains the foundation of protecting your eyes.
Diabetic Retinopathy — Frequently Asked Questions
What are the early symptoms of diabetic retinopathy?
Often none — early diabetic retinopathy is usually symptomless, which is why screening matters. Later signs include blurred or fluctuating vision, floaters, dark areas, night-vision difficulty and washed-out colours. Advanced bleeding can cause sudden vision loss.
Can diabetic retinopathy be cured?
No, but it can be effectively treated to stop or slow progression and preserve vision. Treatments include blood-sugar control, anti-VEGF injections, laser and vitrectomy. Early treatment gives the best outcome.
How much does treatment cost in Turkey?
Sessions typically cost €275–€920: laser $300–$1,000, anti-VEGF injections $200–$1,000, and vitrectomy $2,500–$5,000 per eye — around 60–80% less than the UK, USA or Australia (where a vitrectomy can be $8,000–$14,000).
What's the difference between laser and injections?
Anti-VEGF injections reduce swelling and abnormal vessel growth (standard for macular edema and early proliferative disease); laser seals leaking vessels or shrinks abnormal ones (used for advanced disease). Many patients need a combination. Your ophthalmologist decides based on your stage.
When is surgery (vitrectomy) needed?
In advanced cases with bleeding into the eye (vitreous haemorrhage) or scar tissue pulling on the retina. A vitrectomy removes the vitreous gel and repairs the retina to protect or restore vision.
Can I keep my vision if I have diabetic retinopathy?
In most cases, yes — if it's caught early and treated promptly. Treatment stops progression and preserves remaining vision, with high success rates. Regular screening and good diabetes control are key.
