Which statement about uveitis etiologies is true?

Which statement about uveitis etiologies is true?

• A. It is never caused by trauma
• B. Anterior uveitis is most commonly caused by bacterial conjunctivitis
• C. Trauma is a common cause of anterior uveitis
• D. Toxoplasmosis commonly causes posterior uveitis

Answer: (C)

Uveitis is inflammation inside the eye, and the location of the inflammation helps point to likely causes. Anterior uveitis, which affects the iris and ciliary body, can be triggered by autoimmune/inflammatory processes, but trauma is also a well-recognized cause because injury can disrupt ocular tissues and release antigens that spark intraocular inflammation. This makes trauma a common cause of anterior uveitis, so the statement is true. Bacterial conjunctivitis affects the surface of the eye and does not typically lead to the intraocular inflammation seen in uveitis, so that option isn’t correct. Toxoplasmosis is a well-known cause of posterior uveitis, but the exam’s emphasis here is on the anterior segment and trauma as a common trigger, which is why the trauma-related statement is the best fit.
