Diabetic Retinopathy Treatment in Seomyeon, Busan

What is diabetic retinopathy?

Diabetic retinopathy (당뇨망막병증) develops when long-term high blood sugar weakens the retina's tiny vessels. In the non-proliferative stage, vessels leak blood or fluid. In the proliferative stage, fragile new vessels grow, which can bleed into the eye or pull on the retina. Diabetic macular edema, swelling of the central retina, is the most common cause of vision loss and can occur at any stage.

Symptoms and when to see a doctor

Early stages usually have no symptoms, so regular screening is essential.
Later signs include blurred or fluctuating vision, dark spots or floaters, and difficulty with colour.
Sudden loss of vision or a shower of floaters needs urgent assessment.

What happens at the clinic

Screening: vision, eye pressure and a dilated retina exam.
Imaging: retinal photographs and OCT to detect macular swelling; fluorescein angiography may map leaking vessels.
Staging and plan: mild disease is monitored; macular edema or proliferative disease is treated.
Anti-VEGF injections: medication is injected into the eye under numbing drops, often monthly at first, then spaced out.
Laser or surgery: panretinal laser reduces abnormal vessel growth; vitrectomy removes blood or scar tissue in advanced cases.

Treatment outlook

With timely treatment, many people preserve useful vision. Injection courses can be long-term. Good control of blood sugar, blood pressure and cholesterol slows progression and should be managed with your physician or endocrinologist.

Risks and side effects

Injections can cause temporary discomfort, redness and floaters; infection inside the eye is rare but serious. Laser can reduce peripheral or night vision. Vitrectomy carries surgical risks such as cataract, raised pressure and retinal detachment.

Choosing a clinic for diabetic retinopathy care in Seomyeon

Ask whether a retina specialist manages injections and laser.
Ask whether OCT is performed at each visit to guide treatment.
Ask how the eye clinic communicates with your diabetes doctor.
Ask about the injection schedule and what happens if a visit is missed.
If you travel often, request copies of scans and a treatment summary.

Screening: generally at least yearly for people with diabetes
Key prevention: blood sugar, blood pressure and cholesterol control
Typical NHI coverage: diagnosis and many treatments are NHI-covered for enrolled patients, subject to criteria

Can diabetic retinopathy be reversed?

Damage already done often cannot be fully reversed, but treatment can reduce swelling, stop abnormal vessels and improve vision in many people. Early treatment gives the best results.

Are eye injections painful?

The eye is numbed with drops, so most people feel only brief pressure. Mild scratchiness or a small red spot afterwards is common and temporary.

How often should people with diabetes get an eye exam?

Generally at least once a year, and more often if retinopathy is present or during pregnancy. Your doctor will set the schedule.

Does good blood sugar control help my eyes?

Yes. Controlling blood sugar, blood pressure and cholesterol significantly lowers the risk of retinopathy developing or worsening.

What is diabetic macular edema?

It is swelling of the macula, the centre of the retina, caused by leaking vessels. It blurs central vision and is commonly treated with anti-VEGF injections.
