During assessment of a patient with blunt facial trauma, a hyphema is observed. This finding indicates:

• A. Fracture of the nasal bone.
• B. Pupils unequal.
• C. Direct trauma to the eyeball.
• D. Orbital blowout fracture.

Answer: (C)

A hyphema means blood is visible in the anterior chamber of the eye, which happens when the vessels inside the eye (such as in the iris or ciliary body) are ruptured by trauma. In blunt facial trauma, this finding points to direct injury to the eyeball itself and its internal structures, not just to surrounding bones. So the best interpretation is that there has been direct trauma to the eyeball.

The other injuries describe damage to facial bones or surrounding structures rather than intraocular bleeding. A nasal bone fracture involves the nose and typically causes nasal bleeding and deformity rather than blood in the eye. Unequal pupils suggest a pupil or optic nerve problem, not specifically intraocular bleeding. An orbital blowout fracture involves the orbital bones and can cause double vision or numbness, but it does not explain血 in the anterior chamber.
