**Core Concept**
Fuch's heterochromic iridocyclitis (FHI) is a rare, chronic form of uveitis characterized by heterochromia of the iris, low-grade inflammation, and glaucoma. It is often associated with a systemic condition called Fuch's endothelial dystrophy.

**Why the Correct Answer is Right**
FHI typically presents with a mild, chronic course of uveitis, resulting in a characteristic heterochromia due to the loss of pigmented epithelial cells in the iris. Unlike other forms of uveitis, FHI is not typically associated with pain, redness, or significant vision loss. The inflammation in FHI is usually limited to the anterior segment of the eye, and the patient may not experience the typical symptoms of uveitis.

**Why Each Wrong Option is Incorrect**
**Option A:** FHI is actually characterized by heterochromia of the iris, so this option is incorrect because it is a feature of FHI.
**Option B:** FHI is associated with heterochromia, not a uniform color of the iris.
**Option C:** FHI can lead to glaucoma, which is a serious complication of the disease, so this option is incorrect because it is a feature of FHI.

**Clinical Pearl / High-Yield Fact**
FHI is often associated with Fuch's endothelial dystrophy, a condition characterized by the progressive loss of corneal endothelial cells, leading to corneal edema and vision loss. This association highlights the importance of ophthalmological examination in patients with chronic uveitis.

**Correct Answer:** C.
