Orbital X-Ray or orbital radiography involves study of the area and structures containing the eye. The orbit is the circle of thin bones that protects the eye, even extending behind the eye and nearly wrapping around it. It is useful for detecting fractures of the surrounding bone arising from injury or disease. It is also commonly used for detecting foreign objects in the eye that an ophthalmoscope cannot detect and is sometimes given prior to an MRI where metal fragments could cause significant damage.
