risk factors for


Eye pain

Iritis often causes moderate to severe eye pain, which can be described as a deep, aching sensation. The pain may worsen with eye movement.

The affected eye may appear red or bloodshot. The redness is typically localized to the iris, and the whites of the eye (sclera) may appear normal.

Iritis can make the eye highly sensitive to light (photophobia). Even normal indoor lighting or sunlight can cause discomfort and may lead to squinting or closing the eye in bright environments.

In some cases, iritis can cause a headache, particularly around the affected eye.

Inflammation of the iris can lead to visible changes in the affected eye, such as a dull or swollen appearance. The eye may also feel warm to the touch.

Some individuals with iritis may experience excessive tearing or watery eyes.

 Iritis can cause blurred vision or a decrease in visual acuity. Objects may appear hazy or out of focus.

The pupil of the affected eye may become smaller (constricted) or irregularly shaped. It may also be less responsive to changes in light.

It is important to note that these symptoms can also be indicative of other eye conditions, so it is crucial to consult an eye care professional for a proper diagnosis and appropriate treatment. Early detection and treatment of iritis are essential to prevent complications and preserve vision.

treatment types

Topical Steroid Eye Drops

Corticosteroid eye drops are typically prescribed to reduce inflammation and alleviate symptoms.

Dilating the pupil with specific eye drops helps reduce pain and minimize the risk of complications, such as synechiae (adhesions) between the iris and other eye structures.

 In some cases, oral medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or immunosuppressive agents, may be prescribed to manage inflammation.

Regular check-ups with your eye care specialist are essential to monitor the progress of treatment, adjust medications if needed, and ensure proper healing.

It’s important to note that in many cases, the exact cause of iritis may not be known or identifiable. If you experience symptoms of iritis, such as eye pain, redness, sensitivity to light, and blurred vision, it is important to seek medical attention for proper diagnosis and treatment.

Frequently Asked Questions

What is iritis?

Iritis, also known as anterior uveitis, is an inflammation of the iris, the colored part of the eye. It is a type of uveitis that affects the front part of the eye.

The exact cause of iritis is often unknown, but it can be associated with various factors such as autoimmune diseases (e.g., rheumatoid arthritis, ankylosing spondylitis), infections (e.g., herpes simplex, tuberculosis), trauma to the eye, or certain medications.

Common symptoms of iritis include eye pain, redness, blurred vision, sensitivity to light (photophobia), and a small or irregular pupil. Some individuals may also experience eye floaters or decreased visual acuity.

A comprehensive eye examination is necessary for diagnosing iritis. The eye doctor will evaluate the symptoms, examine the eye using a slit lamp microscope, measure intraocular pressure, and may perform additional tests such as a visual acuity test or a dilated fundus examination.

Treatment of iritis typically involves the use of prescription eye drops, such as corticosteroids or pupil-dilating drops, to reduce inflammation and relieve symptoms. In some cases, oral medications may be prescribed. It is important to follow the prescribed treatment plan and attend regular follow-up appointments.

If left untreated or inadequately treated, iritis can lead to complications such as glaucoma (increased intraocular pressure), cataracts (clouding of the lens), or vision loss. It is crucial to seek prompt medical attention and adhere to the prescribed treatment to prevent complications.

The duration of iritis varies from person to person. It can last anywhere from a few days to several weeks or even months. In some cases, iritis may become chronic and require long-term management.
