Fracture Orbital blow-out.
The condition shown in the picture above represents fracture Orbital blow-out.
Orbital blow-out fractures occur when there is a fracture of one of the walls of orbit but the orbital rim remains intact. Typically, this is caused by a direct blow to the central orbit from a fist or ball.The blow-out fracture is the commonest type of orbital fracture and is usually the result of trauma, often of sporting origin. This is reflected in the demographics and the fact that the commonest group of patients are young men.
Orbital blow-out fractures are usually the result of a direct blow to the orbit. This results in a sudden increase in the intraorbital pressure which in turn causes decompression by fracture of one or more of the bounding walls of the orbit.
The trauma is usually substantial, but presentation and diagnosis may sometimes delayed. This delay is usually due to intact orbital rim (by definition) and swelling making assessment of diplopia and extra-ocular movement difficult.
