**Core Concept**
Dalen-Fuchs nodules are characteristic histopathological findings associated with uveitis, specifically in the context of ocular sarcoidosis and sympathetic ophthalmia. These nodules are formed by the accumulation of epithelioid cells and lymphocytes in the interstitial tissue of the eye, particularly around the retinal pigment epithelium.

**Why the Correct Answer is Right**
The formation of Dalen-Fuchs nodules involves the infiltration of immune cells, including epithelioid cells and lymphocytes, into the interstitial tissue of the eye. This process is a hallmark of chronic inflammation and immune-mediated damage in conditions such as ocular sarcoidosis and sympathetic ophthalmia. The nodules are thought to be a result of the attempt by the immune system to eliminate the perceived threat, leading to tissue damage and inflammation.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because Dalen-Fuchs nodules are not typically associated with viral uveitis, which may present with different histopathological findings.
* **Option B:** This option is incorrect because Dalen-Fuchs nodules are not characteristic of fungal uveitis, which may present with different histopathological findings, such as fungal elements or granulomatous inflammation.
* **Option C:** This option is incorrect because Dalen-Fuchs nodules are not typically associated with autoimmune uveitis, which may present with different histopathological findings, such as vasculitis or lymphocytic infiltration.

**Clinical Pearl / High-Yield Fact**
Dalen-Fuchs nodules are a classic histopathological finding in ocular sarcoidosis and sympathetic ophthalmia, and their presence can help to differentiate these conditions from other forms of uveitis. A high index of suspicion for these conditions is essential in patients with chronic uveitis or those with a history of eye trauma or surgery.

**Correct Answer:** C.
