Uveitis is inflammation of the uvea, the middle layer of the eye, causing pain, redness, light sensitivity, and blurred vision. It can be triggered by infection, autoimmune disease, injury, or occur with no identifiable cause. Treatment usually starts with steroid drops or injections, and finding the underlying cause is essential to prevent recurrence and long-term complications like glaucoma.

Uveitis Explained: Symptoms, Causes & Treatment
Patients often come to me after weeks of being told their red, painful eye is “just an infection” that will not clear with antibiotic drops. Very often, it is not an infection at all. It is uveitis, inflammation inside the eye, and it needs a completely different approach.
Uveitis can affect one or both eyes, strike suddenly or build slowly, and range from a mild, self-limited episode to a chronic condition tied to an underlying autoimmune disease. Left untreated, it can cause glaucoma, cataract, and permanent vision loss. Caught early and treated correctly, most patients recover full vision.
This article explains what uveitis is, why it happens, how we diagnose it, and what treatment actually involves.
Types of Uveitis and What They Mean
| Type | What It Means | What To Do About It |
|---|---|---|
| Anterior uveitis (iritis) | Inflammation of the iris and front chamber; the most common form | Start steroid eye drops promptly and get pressure checked at each visit |
| Intermediate uveitis | Inflammation of the vitreous and area just behind the iris | Needs OCT and vitreous evaluation; often linked to autoimmune conditions |
| Posterior uveitis | Inflammation involving the retina or choroid at the back of the eye | Requires retinal imaging and sometimes systemic treatment beyond eye drops |
| Panuveitis | Inflammation affecting the front, middle, and back of the eye together | Usually needs a rheumatology or infectious disease work-up alongside eye treatment |
| Infectious uveitis | Triggered by tuberculosis, herpes virus, toxoplasmosis, or other infections | Treat the underlying infection first; steroids alone can worsen infectious causes |
| Autoimmune-associated uveitis | Linked to conditions like ankylosing spondylitis, sarcoidosis, or juvenile arthritis | Coordinate care between ophthalmology and rheumatology for long-term control |
Symptoms and What They Signal
| Symptom | What It Means | What To Do About It |
|---|---|---|
| Eye pain, often dull and aching | Common in anterior uveitis, worsens with bright light | Book an appointment within 24 to 48 hours; do not wait it out |
| Redness concentrated around the iris | A pattern called ciliary flush, distinct from typical conjunctivitis redness | Mention this specific pattern to your doctor; it helps narrow the diagnosis quickly |
| Blurred vision | Inflammatory cells clouding the front chamber or vitreous | Avoid driving until vision clears and treatment has started |
| Light sensitivity (photophobia) | The inflamed iris spasms painfully in bright light | Wear sunglasses outdoors, but this does not replace treatment |
| Floaters that appeared suddenly | May indicate intermediate or posterior uveitis affecting the vitreous | Get a dilated retinal exam promptly, not just a front-of-eye check |
| Eye pressure spikes | Inflammation or steroid use itself can raise intraocular pressure | Ask for pressure checks at every visit during treatment, not just at diagnosis |
When To See a Doctor
Seek prompt ophthalmic evaluation, ideally within a day, if you notice:
- One-sided eye pain, redness, or light sensitivity that does not improve with over-the-counter drops
- Sudden blurring of vision or new floaters
- Recurrent episodes of eye redness, especially if you have a known autoimmune condition
- Eye symptoms in a child, particularly with joint pain or stiffness
- Vision changes accompanied by headache, jaw pain, or scalp tenderness in patients over 50
- Any red eye that fails to improve after a few days of antibiotic drops prescribed elsewhere
- Redness or pain following recent eye surgery or injury
Uveitis in older adults with headache and scalp tenderness needs urgent same-day assessment to rule out giant cell arteritis, which can cause sudden permanent vision loss.
Getting Diagnosed: What the Work-Up Involves
- A detailed slit-lamp examination to grade inflammation and check eye pressure
- Dilated retinal examination to rule out posterior or intermediate involvement
- OCT imaging to detect swelling in the retina linked to chronic inflammation
- Blood tests to screen for autoimmune and infectious causes, including tuberculosis screening where relevant
- Chest X-ray or further imaging when sarcoidosis or tuberculosis is suspected
- Referral to rheumatology when an underlying systemic condition is identified
Finding the cause matters as much as treating the current flare, since it shapes how we prevent the next one.
Uveitis Treatment Options
Steroid Therapy
Steroid eye drops are the first-line treatment for anterior uveitis and are usually started at a high frequency, then tapered gradually as inflammation settles. Tapering too quickly is one of the most common reasons uveitis flares up again, so I ask patients to follow the exact schedule given, even once symptoms feel better.
Injections and Systemic Treatment
For intermediate, posterior, or panuveitis, drops alone often are not enough. Steroid injections around or inside the eye may be used, and some patients need oral steroids or immunosuppressive medication to control chronic disease. This is coordinated closely with rheumatology when an autoimmune cause is confirmed. [Neuro-Ophthalmology Hub]
Managing Uveitis-Related Glaucoma
Both the inflammation itself and the steroids used to treat it can raise eye pressure. Patients with a personal or family history of glaucoma need closer monitoring throughout uveitis treatment, since pressure spikes can happen without obvious symptoms. [Glaucoma Hub]
Frequently Asked Questions
What causes uveitis?
Uveitis can be caused by infections such as tuberculosis or herpes virus, autoimmune diseases like ankylosing spondylitis or juvenile arthritis, eye injury, or recent eye surgery. In a significant number of cases, no specific cause is ever identified, which is called idiopathic uveitis.
Is uveitis the same as conjunctivitis?
No, conjunctivitis is inflammation of the eye’s surface and is usually not painful, while uveitis involves inflammation inside the eye and typically causes deeper, aching pain along with light sensitivity. The redness pattern also differs, which is one of the ways we distinguish them on examination.
Can uveitis cause permanent vision loss?
Yes, untreated or poorly controlled uveitis can lead to glaucoma, cataract, retinal swelling, and permanent vision loss. Prompt treatment and consistent follow-up substantially reduce this risk for most patients.
How long does uveitis take to heal?
A single episode of anterior uveitis often improves within a few weeks with proper treatment, though the steroid taper itself takes time. Chronic or autoimmune-associated uveitis can require months to years of ongoing management to prevent recurrence.
Does uveitis come back after treatment?
Yes, recurrence is common, particularly when uveitis is linked to an underlying autoimmune condition that is not fully controlled. Identifying and managing that underlying cause, alongside a proper steroid taper, is the most effective way to reduce future flares.
Can children get uveitis?
Yes, children can develop uveitis, most often associated with juvenile idiopathic arthritis, and it can be silent in its early stages without obvious pain or redness. Regular eye screening is recommended for children diagnosed with juvenile arthritis, even without eye symptoms. [Children’s Eye Care Hub]
Key Takeaways
- Uveitis is inflammation inside the eye and is often mistaken for a stubborn infection or conjunctivitis
- Pain, redness around the iris, light sensitivity, and blurred vision are the core warning signs
- Finding the underlying cause, infectious or autoimmune, is essential for long-term control
- Steroid treatment must be tapered exactly as prescribed to prevent flare-ups
- Untreated uveitis can lead to glaucoma, cataract, and permanent vision loss
- Children with juvenile arthritis need regular eye screening, since uveitis can develop without symptoms
Book a Consultation
If you have a red, painful eye that has not responded to antibiotic drops, or a known autoimmune condition and new eye symptoms, please do not wait. Uveitis responds well to prompt treatment, but delays raise the risk of lasting damage.
I coordinate closely with rheumatology and internal medicine when needed, so your care is complete from the first visit. [Book an Appointment → Contact Us | 8882638735]
