## **Core Concept**
Schwalbe's line is an anatomical landmark in the eye, specifically related to the structure of the cornea and the anterior chamber. It is a critical reference point for ophthalmologists, especially during surgeries and examinations.

## **Why the Correct Answer is Right**
Schwalbe's line represents the termination of Descemet's membrane of the cornea in the eye. Descemet's membrane is a thin, acellular, and transparent layer of the cornea produced by the corneal endothelium. Schwalbe's line marks the junction where Descemet's membrane ends and is a key landmark for understanding the anatomy of the anterior segment of the eye.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Incorrect because it does not accurately describe Schwalbe's line.
- **Option B:** Incorrect as it is not related to the definition of Schwalbe's line.
- **Option C:** This option correctly identifies that Schwalbe's line is the termination of Descemet's membrane, making the other options incorrect by default.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Schwalbe's line is crucial in the diagnosis and surgical management of glaucoma, particularly in procedures like trabeculectomy. Its precise location helps in understanding the angle of the anterior chamber and the presence of any abnormalities.

## **Correct Answer:** C. termination of Descemet's membrane.
