Is Uveitis contagious?

TL;DR: Uveitis is not contagious; you cannot catch it from another person through physical contact, sharing items, or being in close proximity. It is an inflammatory condition of the eye typically driven by autoimmune responses, infections, or underlying systemic diseases, rather than being an infectious disease that spreads between individuals.

Is Uveitis contagious and can it be passed to others?

It is a common concern for patients, but it is important to clarify that uveitis is absolutely not contagious. Whether you are living with, touching, or spending time with someone who has uveitis, there is zero risk of transmission. The condition is an internal inflammatory response within the eye’s uvea—the middle layer of tissue—and does not involve a pathogen that can be "caught" or spread to friends, family, or colleagues.

What causes Uveitis if it is not an infection?

While uveitis is not contagious, its origins are diverse and complex. In many cases, it is classified as an autoimmune condition, where the body’s immune system mistakenly attacks its own healthy eye tissues. In other instances, it may be secondary to a systemic inflammatory disease (such as sarcoidosis, ankylosing spondylitis, or Behçet’s disease) or, less commonly, the result of an infection that originated elsewhere in the patient's own body (such as herpes simplex or toxoplasmosis). Because the inflammation is localized or systemic to the individual's specific health profile, it remains strictly a personal health matter.

Why is there confusion regarding the contagiousness of Uveitis?

The stigma and confusion surrounding uveitis often stem from the fact that the eye may appear red, irritated, or "pink." Because many people associate a red eye with "pink eye" (conjunctivitis), which can be highly contagious, they may mistakenly assume uveitis is similarly infectious. However, unlike conjunctivitis, which typically involves the surface of the eye, uveitis involves deep-seated inflammation inside the eye. Misunderstanding this distinction can lead to unnecessary social isolation for those affected.

What are the common triggers for Uveitis?

While uveitis is not passed between people, certain factors can trigger an episode or worsen existing symptoms. These environmental and biological triggers include:

• Systemic Autoimmune Disorders: Conditions like rheumatoid arthritis or inflammatory bowel disease (IBD) are frequent triggers.


• Trauma: Physical injury to the eye can initiate an inflammatory response.


• Infectious agents: While the uveitis itself isn't spread, infections like syphilis, tuberculosis, or Lyme disease can trigger the inflammation in a susceptible person.


• Smoking: Clinical literature suggests that smoking can exacerbate inflammatory responses and potentially increase the severity of ocular inflammation.

Next steps

• Consult an ophthalmologist or a uveitis specialist (uveitis/ocular immunology expert) for a comprehensive dilated eye exam to determine the specific cause of your inflammation.


• Join the DiseaseMaps.org community to connect with the 135+ members who understand the daily experience of managing this condition.


• Work with your medical team to identify any systemic triggers, such as underlying autoimmune markers, to help prevent future flares.


• Educate friends and family about the non-contagious nature of your condition to help reduce social stigma and isolation.
