Show Hint
Diplopia plus restricted gaze after blunt eye trauma equals orbital floor injury.

- Le Fort fracture
- Fracture maxilla
- Fracture zygomatic
- Blow out fracture
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: The combination of diplopia and restricted eye movements after trauma, with the supporting clinical and CT images, points to an orbital blowout fracture.
Step 2: An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall. It typically results from the impact of a blunt object larger than the orbital aperture (eye socket), which raises intra-orbital pressure and blows out the thin floor.
Step 3: Herniation and entrapment of the inferior rectus and surrounding orbital fat through the floor defect restrict upward gaze and produce the diplopia and limited eye movements described.
Step 4: Le Fort fractures are transverse midface fractures, fracture maxilla and zygomatic fractures involve those facial bones without the classic entrapment picture. The diplopia with gaze restriction and floor defect on CT confirms a blowout fracture.
