## **Core Concept**
Pigmentary glaucoma is a condition characterized by the dispersion of pigment within the eye, leading to increased intraocular pressure (IOP) due to obstruction of the trabecular meshwork by pigment particles. This condition often presents with distinctive clinical features.

## **Why the Correct Answer is Right**
The correct answer, Sampaolesi's line, refers to a specific finding in pigmentary glaucoma. Sampaolesi's line is a deposition of pigment on the posterior surface of the cornea, which is a characteristic feature of this condition. This line is formed by the accumulation of pigment particles on the corneal endothelium. The presence of Sampaolesi's line, along with pigment dispersion in the anterior chamber and elevated IOP, supports the diagnosis of pigmentary glaucoma.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not accurately describe a characteristic feature of pigmentary glaucoma.
- **Option B:** This option is incorrect as it does not relate to the specific clinical findings associated with pigmentary glaucoma.
- **Option C:** This option is incorrect because it does not describe Sampaolesi's line or any other characteristic feature of pigmentary glaucoma.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl for pigmentary glaucoma is that it often affects young to middle-aged males and is associated with pigment dispersion syndrome. A characteristic feature is the presence of Krukenberg's spindle (pigment deposition on the posterior surface of the cornea), which is similar to but not exactly the same as Sampaolesi's line. However, Sampaolesi's line specifically refers to pigment deposition on the anterior surface of the lens.

## **Correct Answer:** . Sampaolesi's line
