What is a common distinguishing feature of lens-induced uveitis?

• A. Cracks in the lens
• B. Presence of uveal cysts
• C. Ulceration of the facial mucocutaneous junctions
• D. Depigmentation of the iris

Answer: (A)

A common distinguishing feature of lens-induced uveitis is indeed the presence of cracks or fissures in the lens. This phenomenon occurs when the lens is affected due to factors like trauma, cataracts, or other ocular conditions. When the lens becomes altered or traumatic, the proteins within it can leak into the surrounding uvea, leading to an inflammatory response. This inflammation manifests as uveitis. The presence of cracks in the lens serves as a critical indicator since it not only suggests direct damage to the lens but also initiates the inflammatory cascade that leads to the symptoms associated with uveitis. This response can potentially result in changes within the eye, including altered intraocular pressure and other ocular manifestations. Other features such as uveal cysts, ulceration of facial mucocutaneous junctions, or depigmentation of the iris are associated with different ocular or systemic conditions, rather than being direct results of lens-induced pathology. While they may occur in various uveal conditions, they do not specifically signify lens-induced uveitis. Therefore, the presence of cracks in the lens is the key distinguishing feature for this condition.
