The role of direct multiplanar high resolution CT in the assessment and management of orbital trauma.

Basic anatomic research has resulted in the discovery of an intricate intraorbital connective tissue system involved in normal eye movements, and in combination with the development of the direct triplane high-resolution CT technique, this research has dramatically improved the treatment of orbital trauma. On the basis of clinical and CT evaluation, four causes of motility impairment after orbital trauma are now recognized and permit patient-tailored treatment methods.
