Iritis: A Serious Eye Condition

Iritis, also known as anterior uveitis, is a condition characterized by inflammation and irritation in the colored ring around your eye's pupil (iris). This can lead to severe vision loss and even blindness if left untreated.

Causes of Iritis

• Inflammatory autoimmune diseases, such as ankylosing spondylitis, lupus, sarcoidosis, and juvenile idiopathic arthritis
• Injury or trauma to the eye
• Reactions to certain medications
• Infectious diseases, including tuberculosis, Lyme disease, syphilis, toxoplasmosis, and histoplasmosis

Symptoms of Iritis

• Severe pain in the eye
• Redness and swelling around the eye
• Sensitivity to light
• Blurred vision or loss of vision
• Eye discharge or pus

Diagnosis of Iritis

• Slit-lamp exam: A special microscope is used to examine the structures inside your eye.
• Visual acuity test: A test to measure your eyesight.

Complications of Untreated Iritis

• Permanent vision loss or blindness
• Glaucoma: Increased pressure in the eye can damage the optic nerve and lead to vision loss.
• Cataracts: Clouding of the lens in the eye can affect vision.

According to [4], iritis is a serious condition that requires prompt medical attention. If left untreated, it can cause severe vision loss and even blindness. The causes of iritis are varied, including autoimmune diseases, injury, medication reactions, and infectious diseases. Symptoms include severe pain, redness, sensitivity to light, blurred vision, and eye discharge.

Symptoms of Iris Disease

Iris disease, also known as iritis, can cause a range of symptoms that may vary in severity. The following are some common signs and symptoms of iris disease:

• Eye redness: One or both eyes may become red and inflamed.
• Discomfort or achiness: Patients may experience discomfort or achiness in the affected eye.
• Sensitivity to light: Iritis can cause sensitivity to light, making it uncomfortable for patients to be in bright environments.
• Decreased vision: In some cases, iritis can lead to decreased vision or blurred vision.
• Fever and fatigue: Some people may experience fever, fatigue, and night sweats as symptoms of immune reconstitution inflammatory syndrome (IRIS), a condition that can occur with iris disease.

Additional Symptoms

In addition to the above symptoms, some people may also experience:

• Headaches: Headaches are a common symptom of IRIS.
• Increased intracranial pressure: In rare cases, IRIS can cause increased intracranial pressure.
• Evidence of granuloma formation on neuroimaging: This is a sign of IRIS affecting the brain.

Symptoms by Type

The symptoms of iris disease can vary depending on the underlying condition. For example:

• Acute iritis: Symptoms develop suddenly, over hours or days.
• MAC IRIS during immune recovery: Symptoms may include fever, fatigue, and night sweats.
• PML-IRIS: Symptoms can worsen PML symptoms.
• TB-IRIS: Symptoms may include fever, lymphadenopathy, and worsening respiratory symptoms.

Diagnostic Tests for Iris Disease

Iris diseases, such as iritis or uveitis, can be challenging to diagnose due to their complex nature. However, various diagnostic tests can help identify the underlying condition.

• Blood tests: Blood tests are commonly used to check for autoimmune diseases, infections, and other conditions that may be causing the iris disease [5]. These tests can include:
  • Tests to check for autoimmune diseases, such as rheumatoid arthritis or lupus
  • Blood tests to check for infection, such as bacterial or viral infections
• Imaging tests: Imaging tests are used to visualize the internal structures of the eye and detect any abnormalities. These tests may include:
  • Chest X-ray or CT scan of the chest to look for signs of tuberculosis or other infections [5]
  • Computed Tomography (CT) scans or Magnetic Resonance Imaging (MRI) scans to evaluate the extent of inflammation
• Ultrasound biomicroscopy (UBM): UBM is a non-invasive test that uses high-frequency sound waves to produce detailed images of the eye's internal structures [6]. This test can help identify synechiae, where the iris sticks to the lens or cornea.
• Optical Coherence Tomography (OCT): OCT is a non-invasive imaging test that uses low-coherence interferometry to produce high-resolution images of the eye's internal structures [6]. This test can help evaluate the extent of inflammation and detect any abnormalities in the iris.

It's worth noting that there are no accepted diagnostic tests for an IRIS (Immune Reconstitution Inflammatory Syndrome), and diagnosis is made clinically based on the temporal relationship between the initiation of effective treatment and the onset of symptoms [4].

Treatment Options for Immune Reconstitution Inflammatory Syndrome (IRIS)

IRIS can be challenging to treat, but various approaches have been reported in medical literature. Here are some treatment options:

• Non-steroidal anti-inflammatory drugs (NSAIDs): These medications may be used to manage mild cases of IRIS, reducing inflammation and alleviating symptoms [2].
• Corticosteroids: In more severe cases, corticosteroids can be prescribed to reduce inflammation and prevent further complications. However, the risk-benefit should be carefully assessed, particularly for patients with mycobacterial disease [3].
• Specific treatment for opportunistic infections (OIs): IRIS often resolves on its own once the underlying OI is treated. In some cases, continuation of specific treatment for the OI may be necessary without discontinuing antiretroviral therapy (ART) [4].

Important Considerations

• Interrupting combination ART in a patient with IRIS may lead to acquisition of new opportunistic infections, recurrence of symptoms, or worsening of the condition [5].
• Mild cases of IRIS often resolve over time with symptomatic treatment alone. However, severe cases can threaten a patient's functional status or cause permanent disability or death [6].
