Vogt's striae occur in which layer of the cornea?

• A. Epithelium
• B. Stroma
• C. Descemet's membrane
• D. Endothelium

Answer: (C)

Vogt's striae are lines seen in the cornea that result from stress and distortion, primarily related to the corneal stroma's response to changes in intraocular pressure or other mechanical forces. These striae represent a form of stretching that occurs in Descemet's membrane, which is the thin layer of tissue located between the corneal stroma and the endothelium. In contrast, the other layers of the cornea do not typically manifest Vogt's striae. The epithelium serves as the outer protective layer and is primarily involved in barrier functions and sensory perception. The stroma is the thickest layer and consists of collagen fibers, providing structural support but not associated with the formation of Vogt's striae. The endothelium is the innermost layer responsible for maintaining corneal clarity and fluid balance but does not exhibit these specific stress markings. Therefore, Vogt's striae being specifically associated with Descemet's membrane highlights how this particular layer can be affected by tensile forces, making it the correct response in this context.
