Uveitis: Causes, Symptoms, Diagnosis & Treatment in Dubai

A red eye that hurts, feels unusually sensitive to light, or suddenly develops floaters deserves more attention than a simple case of irritation. These symptoms can sometimes be caused by uveitis, an inflammation inside the eye that can affect vision if it is not diagnosed and treated in time. Uveitis can affect different parts of the eye, so it does not look or feel the same in everyone. Some people develop a painful, red eye within a short period, while others mainly notice blurred vision, floaters or a gradual change in how clearly they see. The inflammation may be linked to an infection, an autoimmune or inflammatory condition, an eye injury, or may occur without an identifiable cause. For patients seeking uveitis treatment in Dubai, identifying where the inflammation is occurring and what may be triggering it is an important first step. At Vasan Eye Care, an ophthalmologist evaluates the eye in detail before deciding whether treatment, further testing or ongoing monitoring is required.

What Is Uveitis?

Uveitis is inflammation of the uvea, the middle layer of the eye. The uvea includes the iris, ciliary body and choroid, but inflammation can also affect surrounding structures inside the eye. The condition does not always present in the same way. When inflammation is limited to the front of the eye, it is usually called anterior uveitis. When the inflammation affects the vitreous or deeper structures, it may be classified as intermediate or posterior uveitis. When several parts of the eye are involved, it is known as panuveitis. This difference matters because the location of the inflammation influences the symptoms, investigations and treatment required.

Uveitis can occur for many reasons, and sometimes the cause remains unknown. What matters is recognising the signs and having the eye examined rather than assuming that redness or blurred vision is simply an infection or irritation.

Types of Uveitis

Doctors classify uveitis according to the part of the eye where the inflammation occurs. This classification helps determine the appropriate examination and treatment.

Anterior Uveitis

Anterior uveitis affects the front of the eye, particularly the iris and ciliary body. When the iris is inflamed, the condition is commonly referred to as iritis. It can develop suddenly as acute iritis, with symptoms such as eye pain, redness, blurred vision and strong sensitivity to light. Some people experience one episode and recover with treatment, while others may have recurrent inflammation.

Intermediate Uveitis

Intermediate uveitis affects the middle portion of the eye, particularly the vitreous and the area around the pars plana. Pain and redness may be less obvious than in anterior uveitis. Instead, people may notice floaters, hazy vision or a gradual reduction in visual clarity. The inflammation may persist for a longer period or return after a period of improvement.

Posterior Uveitis

Posterior uveitis affects the back of the eye, including the retina and choroid. Since these structures have a direct role in vision, inflammation in this area can cause blurred or reduced vision, floaters and visual field changes. It may not produce an obviously red eye, which is one reason why changes in vision or new floaters should not be ignored.

Panuveitis

Panuveitis occurs when inflammation involves the front, middle and back portions of the eye. Because several structures can be affected at the same time, symptoms may include eye redness, pain, light sensitivity, floaters and significant changes in vision. It generally requires a detailed assessment to determine the underlying cause and extent of inflammation.

What Are the Symptoms of Uveitis?

The uveitis symptoms you experience depend on the location and severity of the inflammation. Some forms produce obvious pain and redness, while others mainly affect vision. Uveitis common symptoms include:

• Eye redness
• Eye pain or aching
• Sensitivity to light
• Blurred or hazy vision
• New floaters or dark spots
• Reduced vision
• Changes in the visual field
• A small or irregular-looking pupil in some cases

Symptoms can develop suddenly or gradually. Uveitis may affect one eye or both eyes, and symptoms can sometimes improve temporarily before returning. A painful red eye with blurred vision should not automatically be treated as conjunctivitis. Several eye conditions can look similar at first but require very different treatment.

What Causes Uveitis?

There is no single cause of uveitis. In some people, the inflammation is associated with another medical condition or infection. In others, no definite trigger can be found. Understanding the possible uveitis causes helps an ophthalmologist decide whether further investigations are necessary.

• Autoimmune and Inflammatory Conditions such as ankylosing spondylitis, rheumatoid arthritis, inflammatory bowel disease, sarcoidosis, lupus and Behçet’s disease.
• Infections such as herpes simplex virus, varicella-zoster virus, tuberculosis, syphilis and toxoplasmosis.
• Eye Injury or Surgery
• Medicines (Rare cause)

Sometimes no specific cause can be identified despite appropriate evaluation. This is referred to as idiopathic uveitis.

How Is Uveitis Diagnosed?

A proper uveitis diagnosis involves more than looking at the redness of the eye. The ophthalmologist needs to determine where the inflammation is located, how active it is and whether there is an underlying cause.

Your doctor may first ask when the symptoms started, whether they have occurred before and whether you have experienced any recent infection, injury or other health problems. Your current medicines and previous eye history may also be relevant.

The eye examination can include:

• Visual acuity testing checks whether the inflammation has affected your ability to see clearly.
• Slit-lamp examination provides a magnified view of the front of the eye and allows the ophthalmologist to identify signs of inflammation.
• Eye pressure measurement is important because both uveitis and some medicines used to treat it can affect intraocular pressure.
• Dilated retinal examination allows the doctor to examine the retina, choroid and optic nerve when inflammation may extend to the back of the eye.
• OCT and other imaging tests may be used to look for retinal swelling or other changes that are not visible during a routine examination.

Further investigations may be recommended when uveitis is recurrent, affects both eyes, involves the posterior part of the eye or appears to be associated with an infection or systemic inflammatory condition.

The aim of the assessment is not simply to confirm that inflammation is present. It is to understand the type of uveitis, its severity and its possible cause, so treatment can be selected appropriately.

Uveitis Treatment in Dubai

The right uveitis treatment depends on where the inflammation is occurring, how severe it is and what has caused it.

For Anterior Uveitis, treatment may include:

• Corticosteroid eye drops to reduce inflammation
• Dilating eye drops to relieve pain and prevent adhesions
• Regular eye pressure checks during treatment

Depending on the severity and location of inflammation,  Intermediate and Posterior Uveitis treatment may include:

• Oral anti-inflammatory medicines
• Injections around or inside the eye
• Immune-modulating treatment for persistent cases
• Retinal imaging and regular monitoring

When a cause is identified, treatment may include:

• Antiviral or antimicrobial medicines for infections
• Treatment for autoimmune or inflammatory conditions
• Specialist care for underlying systemic conditions
• Long-term treatment for recurrent uveitis

Monitoring During Treatment includes:

• Track inflammation and vision changes
• Monitor eye pressure
• Check for treatment-related complications
• Adjust treatment when needed

Note: You must always not use any medication or drops without doctor consultation. 

Can Uveitis Affect Your Vision?

Yes. Uveitis can affect vision when inflammation involves the retina, macula, optic nerve or other structures responsible for clear sight. Some people experience temporary blurred vision that improves once the inflammation is controlled. However, prolonged or severe inflammation can lead to complications that have a lasting effect on vision. The risk depends on the type of uveitis, its severity, the underlying cause and how quickly appropriate treatment begins.

What Happens If Uveitis Is Left Untreated?

Leaving eye inflammation untreated can allow the inflammatory process to continue and increase the risk of damage to the eye. Depending on which structures are affected, untreated uveitis may contribute to cataracts, glaucoma, retinal swelling, retinal damage, optic nerve problems or permanent loss of vision.

This does not mean every case of uveitis will lead to serious complications. Early diagnosis, appropriate treatment and regular monitoring can help control inflammation and protect the eye.

When Should You See an Ophthalmologist?

A new red eye does not always require emergency treatment, but certain symptoms should not be ignored. Arrange an ophthalmic assessment if you develop:

• Eye redness with pain
• Significant sensitivity to light
• Blurred or hazy vision
• New floaters
• Reduced vision
• Recurrent episodes of similar symptoms

Seek urgent eye care if you experience sudden vision loss, severe eye pain, rapidly worsening vision or a sudden increase in floaters or flashes of light. If you have had uveitis before, similar symptoms may indicate that the inflammation has returned and should be assessed promptly.

Uveitis Treatment at Vasan Eye in Dubai

For patients seeking uveitis treatment in Dubai, Vasan Eye Care provides ophthalmic evaluation to determine whether the symptoms are related to uveitis and identify the area of the eye involved.

The assessment may include visual acuity testing, slit-lamp examination, eye pressure measurement, dilated retinal examination and imaging where clinically appropriate. When the findings suggest an underlying infection, inflammatory condition or other systemic cause, additional investigations may be recommended.

Treatment is selected according to the type, severity and cause of the inflammation. Patients may require prescription eye drops, other anti-inflammatory treatment, treatment for an underlying infection or continued monitoring for recurrent inflammation.

If you are experiencing eye redness, eye pain, light sensitivity, blurred vision or new floaters, consult an ophthalmologist in Dubai rather than assuming the symptoms are simple conjunctivitis.

Frequently Asked Questions About Uveitis

1. What is uveitis?

Uveitis is inflammation of the uvea, the middle layer of the eye that includes the iris, ciliary body and choroid. Depending on the part of the eye affected, uveitis can cause redness, pain, light sensitivity, floaters, blurred vision or reduced vision.

2. Is uveitis a serious condition?

Uveitis can become serious if inflammation is severe, persistent or left untreated. It can affect structures involved in vision and may lead to complications such as cataracts, glaucoma, macular oedema, retinal damage or permanent vision loss.

3. Can uveitis cause permanent vision loss?

Yes, severe or untreated uveitis can cause permanent vision loss if inflammation damages the retina, macula, optic nerve or other important structures. Early diagnosis and appropriate treatment can help reduce this risk.

4. Can uveitis come back after treatment?

Yes, uveitis can recur, particularly when it is associated with an inflammatory or autoimmune condition. Anyone who develops similar symptoms after previous treatment should have the eye examined rather than restarting old medicines without medical advice.

5. Is uveitis contagious?

Uveitis itself is not contagious. However, some infections that can cause uveitis may be transmissible, which is why identifying the underlying cause is important when an infection is suspected.

6. How long does uveitis take to heal?

The recovery time varies according to the type and severity of uveitis and its underlying cause. Some cases of anterior uveitis improve over several weeks with appropriate treatment, while intermediate, posterior or recurrent uveitis may require longer-term treatment and monitoring.

7. What is the difference between uveitis and iritis?

Iritis refers specifically to inflammation of the iris, while uveitis is a broader term for inflammation involving the uvea. Therefore, iritis is considered a form of anterior uveitis.

8. What is the difference between uveitis and conjunctivitis?

Conjunctivitis affects the surface of the eye and commonly causes irritation, itching, watering or discharge. Uveitis affects deeper structures and is more likely to cause eye pain, light sensitivity, blurred vision or floaters. An ophthalmic examination is needed to distinguish between them when symptoms overlap.

9. When should I see an ophthalmologist for uveitis symptoms?

You should see an ophthalmologist promptly if you develop a painful red eye, significant light sensitivity, blurred vision or new floaters. Sudden vision loss, severe eye pain, rapidly worsening vision or a sudden increase in floaters or flashes requires urgent assessment.

10. Where can I get uveitis treatment in Dubai?

Patients looking for uveitis treatment in Dubai can consult an ophthalmologist at Vasan Eye Care for an eye examination, diagnosis and treatment plan based on the type, severity and possible cause of the inflammation.
