All can occur due to blunt trauma of eye except ?
**Core Concept**
Blunt trauma to the eye can cause a variety of injuries due to the transmission of force to the delicate structures within the eye. The eye is particularly vulnerable to blunt trauma due to its anterior location and the presence of air-filled spaces, which can amplify the force of the impact.
**Why the Correct Answer is Right**
The correct answer will be an injury that is not typically associated with blunt trauma to the eye. The eye is susceptible to injuries such as **hyphema** (bleeding into the anterior chamber), **commotio retinae** (a condition characterized by retinal edema and opacification), and **orbital emphysema** (air trapping in the orbital tissues). However, certain injuries are less commonly associated with blunt trauma.
**Why Each Wrong Option is Incorrect**
**Option A:** Hyphema is a common consequence of blunt trauma to the eye, often due to the rupture of small blood vessels in the iris or ciliary body. **Option B:** Commotio retinae is a well-documented complication of blunt ocular trauma, resulting from the transmission of force to the retina. **Option D:** Orbital emphysema can occur due to blunt trauma, particularly if there is a fracture of the orbital bones or a disruption of the orbital tissues.
**Clinical Pearl / High-Yield Fact**
It is essential for clinicians to recognize the signs of blunt ocular trauma, including hyphema, commotio retinae, and orbital emphysema, as these conditions can lead to significant morbidity if not promptly treated.
**Correct Answer: C.**
