Hyphema refers to blood in which part of the eye?

• A. Hyphema
• B. Subconjunctival hemorrhage
• C. Hypopyon
• D. Cataract

Answer: (A)

Hyphema is blood located in the anterior chamber of the eye, the space between the cornea and the iris. This distinction matters because it tells you the blood is inside the eye rather than on the surface. Subconjunctival hemorrhage involves bleeding under the conjunctiva on the surface of the eye and does not affect the anterior chamber or vision in most cases. Hypopyon is blood-tinged or pus-filled material layering in the anterior chamber due to inflammatory or infectious processes, not simple bleeding. Cataract refers to opacification of the lens, which dulls or blocks vision but isn’t about blood in the anterior chamber.
