Where is Schwalbe line located?

• A. Marks the outer limit of the cornea to the limbus
• B. Represents the termination of Descemet's membrane
• C. A connection between the iris and cornea
• D. The posterior surface of the lens

Answer: (B)

Schwalbe line is the peripheral boundary where Descemet’s membrane ends, marking the transition between the corneal endothelium/Descemet’s membrane and the trabecular meshwork near the limbus. This is why it’s described as the termination of Descemet’s membrane. The outer limit of the cornea to the limbus refers to the limbus itself, not Schwalbe line; there isn’t a direct iris–cornea connection at this spot, and the posterior surface of the lens is a different structure altogether.
