Uveitis (Eye Inflammation): Symptoms, Causes & Treatment in Seoul
A board-certified ophthalmologist explains this vision-threatening condition for Seoul residents
Q. What is uveitis and how is it treated in Seoul?
Uveitis is inflammation of the uvea — the iris, ciliary body, and choroid inside the eye — causing eye pain, redness, light sensitivity, and blurred vision. It can be triggered by autoimmune conditions, infections, or occur with no identifiable cause, and treatment ranges from corticosteroid eye drops for mild anterior cases to systemic immunosuppressive therapy for recurrent or vision-threatening disease. Prompt evaluation matters, since untreated uveitis can lead to glaucoma, cataract, or permanent vision loss.
Q. What causes uveitis?
Uveitis has three broad categories of causes. Autoimmune and systemic inflammatory conditions — including ankylosing spondylitis, sarcoidosis, juvenile idiopathic arthritis, and Behçet’s disease — are common triggers, and notably, Behçet’s disease-associated uveitis is significantly more prevalent in Korea and East Asia than in Western populations, often presenting as recurrent, severe posterior or panuveitis. Infections such as herpes simplex, herpes zoster, tuberculosis, and toxoplasmosis are another major cause. In many patients, particularly those with isolated anterior uveitis, no specific cause is ever identified despite thorough workup, and the condition is classified as idiopathic.
Uveitis — Key Facts
- ▸ Anterior uveitis (iritis) is the most common form and is frequently linked to the HLA-B27 gene marker.
- ▸ Behçet’s disease-associated uveitis occurs more often in Korea and East Asia than in Western populations, and tends to be more severe.
- ▸ Left untreated, uveitis is a recognized cause of preventable vision loss worldwide.
- ▸ A substantial proportion of patients experience at least one recurrence within two years of their first episode.
Q. How is uveitis treated?
Anterior uveitis usually responds well to corticosteroid eye drops combined with a cycloplegic (pupil-dilating) drop, which reduces pain and helps prevent the iris from sticking to the lens. Intermediate and posterior uveitis, which involve deeper structures, often require periocular or intravitreal steroid injections, since drops alone may not reach the back of the eye effectively.
For recurrent, bilateral, or vision-threatening uveitis — particularly cases associated with Behçet’s disease or other systemic autoimmune conditions — oral corticosteroids or steroid-sparing immunosuppressants such as methotrexate, azathioprine, or biologic agents may be necessary, usually managed jointly with a rheumatologist.
Q. When should residents of Yeongdeungpo, Guro, or Gasan see a doctor?
Sudden eye pain, redness concentrated around the iris, light sensitivity, or blurred vision should be evaluated the same day if possible, rather than waiting to see if it resolves. Patients in Yeongdeungpo, Guro, Gasan, and Gwanak with these symptoms — especially if they have a known autoimmune condition or a history of recurrent eye inflammation — should not delay, since early treatment significantly reduces the risk of complications like elevated eye pressure or macular edema.
Q. What signs suggest uveitis rather than simple eye irritation?
- Deep, aching eye pain rather than surface itchiness or grittiness
- Redness concentrated in a ring around the iris (ciliary flush) rather than spread across the white of the eye
- Marked sensitivity to light
- Blurred vision or new floaters, particularly in one eye
- Symptoms that recur after a previous episode
Anterior Uveitis
Inflammation of the iris and ciliary body — the most common type, often linked to HLA-B27.
Intermediate Uveitis
Affects the vitreous and peripheral retina, can cause floaters and blurred vision.
Posterior / Panuveitis
Involves the choroid and retina, or all layers — more often linked to Behçet’s disease in Korea.
From Dr. Daniel Baik
“Uveitis is one of the conditions where speed really matters — a patient who comes in the same day their eye turns red and painful almost always does better than one who waits a week. In my experience treating patients across Guro and Yeongdeungpo, catching it early is what protects long-term vision, especially in recurrent or Behçet’s-related cases.” — Dr. Daniel Baik, board-certified ophthalmologist
❓ Frequently Asked Questions
Q. What is the difference between uveitis and conjunctivitis?
Conjunctivitis affects the surface membrane of the eye and is usually itchy with watery or sticky discharge, while uveitis involves deeper structures and typically causes aching pain, light sensitivity, and blurred vision without significant discharge. Uveitis requires prompt ophthalmology evaluation and does not resolve with over-the-counter allergy or antibiotic drops.
Q. Is uveitis linked to Behçet’s disease in Korea?
Yes. Behçet’s disease-associated uveitis is more common in Korea and East Asia than in Western countries, and tends to present as recurrent, often severe posterior or panuveitis. Patients with recurrent uveitis are typically screened for Behçet’s disease and other systemic autoimmune conditions.
Q. Can uveitis cause permanent vision loss if untreated?
Yes. Untreated or poorly controlled uveitis can lead to glaucoma, cataract, macular edema, and permanent scarring, all of which can permanently reduce vision, which is why early diagnosis and treatment are so important.
Q. How long does treatment for uveitis take?
A single mild episode of anterior uveitis may resolve within a few weeks with steroid drops, while recurrent or systemic-disease-associated uveitis can require months to years of ongoing management, sometimes with periodic flare-ups even during treatment.
Q. Will I need to see a rheumatologist as well as an ophthalmologist?
Often, yes, particularly for recurrent, bilateral, or posterior uveitis, since an underlying systemic autoimmune or inflammatory condition is frequently involved. Your ophthalmologist can coordinate this referral when bloodwork or your clinical picture suggests it.
Q. Can uveitis come back after it clears up?
Yes, recurrence is common, especially in cases linked to HLA-B27 or Behçet’s disease. Patients with a history of uveitis should seek prompt evaluation at the first sign of redness or pain returning, rather than waiting to see if it resolves on its own.
Q. Does Nunehim Eye Center treat uveitis for patients in Yeongdeungpo, Guro, Gasan?
Yes. Nunehim Eye Center evaluates and manages uveitis for patients across Yeongdeungpo, Guro, Gasan, and Gwanak, including coordinating referrals for underlying systemic conditions when needed, with consultations in Korean and English.
