**Core Concept**
Uveitis is a form of eye inflammation involving the uvea, which includes the iris, choroid, and ciliary body. Certain medications can exacerbate or trigger uveitis, making their use contraindicated in affected individuals.

**Why the Correct Answer is Right**
The correct answer is **C. Atropine**, which is an anticholinergic medication that can cause mydriasis (pupil dilation) and cycloplegia (paralysis of accommodation). In uveitis, the use of atropine can worsen the condition by causing further irritation and inflammation of the iris and ciliary body. This is because atropine can stimulate the sympathetic nervous system, leading to increased intraocular pressure and exacerbation of the inflammatory response.

**Clinical Pearl / High-Yield Fact**
In patients with uveitis, it's essential to avoid using medications that can exacerbate the condition. A key principle in managing uveitis is to use medications that reduce inflammation and promote healing, such as corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs).
