## **Core Concept**
Koeppe's nodules are associated with a specific condition affecting the eye, particularly in the context of uveitis. They are a type of inflammatory lesion. Understanding the nature of Koeppe's nodules requires knowledge of ocular pathology and immunology.

## **Why the Correct Answer is Right**
Koeppe's nodules are specifically identified as a type of inflammatory nodule found at the pupillary margin in patients with certain types of uveitis, notably in conditions like granulomatous uveitis. They are considered a form of granulomatous inflammation. The correct classification of Koeppe's nodules as **iris nodules** or specifically related to the iris is crucial for understanding their clinical significance and association with systemic diseases.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because Koeppe's nodules are not primarily described as lesions unrelated to the iris or uveitis.
- **Option B:** This option might seem plausible but does not accurately describe Koeppe's nodules.
- **Option C:** This is the correct classification; hence, discussing its incorrectness is not applicable here but will be acknowledged as right in the correct answer section.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Koeppe's nodules are often associated with granulomatous forms of uveitis and can be seen in conditions such as sarcoidosis, tuberculosis, and sympathetic ophthalmia. Recognizing these nodules can aid in the diagnosis and management of the underlying condition.

## **Correct Answer:** C. Iris nodules.
