Sample question 1
Explanation
At the limbus, the transparent cornea transitions into the opaque sclera. This junction is an important anatomic landmark in gonioscopy and anterior segment surgery. The iris and lens are internal structures and are not continuous with the corneal tissue in this way.
Sample question 2
Explanation
The corneal endothelium maintains relative stromal dehydration through metabolically active pump function. This is essential for corneal clarity. Significant endothelial dysfunction leads to stromal edema and loss of transparency.
Sample question 3
Explanation
The corneal epithelium is the outermost corneal layer and is bathed by the tear film. It serves as a barrier against infection and injury. The endothelium lines the posterior corneal surface, not the anterior surface.
