Abstract
During the past decade, the diagnosis and treatment of orbital and periorbital trauma has benefited greatly from advances in several areas, including radiological imaging, surgical techniques and instruments, and studies of the natural course of posttraumatic sequels. For the surgeon dealing with trauma, there are now many new technologies that allow for earlier rehabilitation and decreased morbidity of patients through a greater emphasis on the restoration of the functional anatomy of the traumatized orbit. (Maus, et al. 2001)
Ocular and periocular injuries are common in patients with severe trauma, especially when the face and head is involved. (Sastry, et al. 1993)
In a patient with acute orbital trauma, visual acuity and extraocular muscle motility are the nvo most important ophthalmologic functions to be evaluated emergently. The assessment of these capabilities may sometimes be difficult due to the severity of the head injury, the extent of periorbital soft tissue edema, inadequate cooperation in alert patients, and a reduced level of consciousness in obtunded individuals. (Lee, et al. 2004)
Vision-threatening injuries, however, often require immediate treatment to provide the best chance of optimal visual outcome. Visual loss becomes a significant concem once the acute stage of trauma management has passed because it impedes rehabilitation and dramatically reduces the quality of life. (Poon, et al. 1999)
