Is Pars Planitis contagious?

Pars planitis is not a contagious disease and cannot be spread from person to person through touch, air, or any form of social contact. It is a chronic, non-infectious inflammatory condition of the eye, specifically affecting the intermediate uvea, and poses absolutely no risk of transmission to family, friends, or caregivers.

Is Pars planitis contagious?

There is no risk of transmission associated with Pars planitis. Because the condition is not caused by viruses, bacteria, or fungi, there is no biological mechanism for it to spread. Living with, hugging, or sharing personal space with someone diagnosed with Pars planitis is completely safe. Patients should feel reassured that their condition does not require isolation or special precautions to protect others.

What causes Pars planitis?

The exact cause of Pars planitis remains idiopathic, meaning it occurs without a known external trigger. Current medical consensus categorizes it as an autoimmune or inflammatory disorder where the body’s immune system mistakenly attacks the tissues of the eye. While the cause is not infectious, researchers are investigating the following factors that may contribute to the development of Pars planitis:

• Systemic inflammatory conditions, such as sarcoidosis or multiple sclerosis.


• Genetic predisposition, though Pars planitis is not considered a strictly inherited Mendelian disease.


• Immune system dysregulation resulting in the accumulation of inflammatory cells (snowbanking) in the pars plana region of the eye.

Why is there confusion regarding contagion?

Confusion often arises because Pars planitis is a form of uveitis, and some types of uveitis can be caused by infectious agents like tuberculosis or syphilis. However, Pars planitis itself is distinctively non-infectious. The stigma associated with eye redness or inflammation can lead to unnecessary social anxiety, but it is vital to emphasize that Pars planitis is an internal inflammatory process, not a communicable illness.

Next steps

• Consult an ophthalmologist specializing in uveitis for a comprehensive diagnostic workup.


• Connect with the 21 members of the DiseaseMaps.org community who are living with Pars planitis to share experiences.


• Keep a symptom log to track flare-ups, which may help your physician identify potential environmental triggers unique to you.
