Understanding Uveitis: Symptoms, Causes, and Treatment Options

Uveitis is a term used to describe various eye conditions that cause inflammation and swelling, potentially leading to vision loss or even blindness if left untreated. The inflammation usually affects the uvea, the middle layer of the eye, which includes the iris, ciliary body, and choroid.

Types of Uveitis

There are different types of uveitis, depending on which part of the eye is affected:

• Anterior uveitis: Affects the front of the eye and is the most common type

• Intermediate uveitis: Affects the ciliary body

• Posterior uveitis: Affects the back of the eye

• Panuveitis: Occurs when the entire uvea is inflamed

Causes of Uveitis

Uveitis can be caused by various factors, including:

• Autoimmune diseases, such as rheumatoid arthritis, sarcoidosis, or multiple sclerosis

• Infections, like herpes zoster, syphilis, or tuberculosis

• Eye injuries or bruises

• Toxic substances entering the eye

• Tumors in the eye or other parts of the body

Some people may be at a higher risk of developing uveitis, including those with certain gene combinations, smokers, and individuals with specific diseases like AIDS, psoriasis, or ulcerative colitis.

Symptoms of Uveitis

Uveitis symptoms can affect one or both eyes and may appear suddenly or gradually. Common warning signs include:

• Eye redness

• Pain

• Blurry or reduced vision

• Sensitivity to light

• Floaters (tiny dots or specks in your vision)

If you experience any of these symptoms, it's crucial to consult your eye doctor promptly for an accurate diagnosis and appropriate treatment.

Diagnosing Uveitis

To diagnose uveitis, your eye doctor will review your medical history and overall health, as uveitis can be linked to other diseases. They may order blood tests, skin tests, or X-rays, in addition to conducting a comprehensive eye exam.

Treatment Options for Uveitis

Treatment for uveitis typically begins with eye drops containing corticosteroids to reduce inflammation. Dilating eye drops may also be prescribed to prevent scarring and relax eye muscles. If eye drops are ineffective, your doctor may recommend oral medications or injections.

In cases where an infection is causing uveitis, antibiotics or antiviral drugs may be prescribed. For severe or unresponsive cases, stronger medications like immunosuppressives may be used in combination with corticosteroids. In some instances, an implantable device that slowly releases medication or a procedure to remove some of the vitreous (gel-like substance) in the eye may be recommended.

Adhering to your treatment plan and attending follow-up appointments with your doctor are essential for preventing serious complications and preserving your vision. Always report any new symptoms to your healthcare provider.
