Test Criteria

X-ray of the orbits is used to visualise the area of both the eye sockets (ring of thin bones which contains the eye), nasal bridge and the cheekbones. The image is recorded on a special X-ray film using small amount of radiation. The X-ray image is black and white. Dense structures such as the bones, appear white and softer body tissues, such as the skin and muscles appear darker. The actual exposure time to radiation is usually less than a second, although the overall test may take 15-20 minutes.
