Which of the following is a specific sign of active uveitis?

• A. Cataracts
• B. Posterior synechia
• C. Miosis
• D. Epiphora

Answer: (C)

Active uveitis is characterized by inflammation of the uveal tract, which consists of the iris, ciliary body, and choroid. One of the specific signs associated with active uveitis is miosis, which is the constriction of the pupil. This occurs because the inflamed iris responds to the underlying condition by constricting, often as a reflex to reduce light exposure and protect the sensitive tissues. In cases of uveitis, the inflammation can cause discomfort and pain, leading to reflexive changes in pupil size. Miosis, in particular, is often observed alongside other signs of inflammation, such as redness and increased intraocular pressure. This reaction is important in diagnosing uveitis as it indicates an inflammatory response occurring in the eye. While cataracts, posterior synechiae, and epiphora can occur in the context of eye disease, they are not specific signs of active uveitis. Cataracts typically result from damage to the lens or long-standing inflammation but do not indicate present inflammation. Posterior synechia, which is the adhesion of the iris to the lens, is more of a consequence of chronic uveitis rather than a sign of active inflammation. Epiphora, or excessive tearing, can
