An analytical cross-sectional study of the axial computed tomography (ACT) of orbit carried out within the period from december 1998 to december 2000 at Manuel Ascunce Domenech provincial hospital of Camagüey, with clear assumption of expansive intraorbitary processes to which a diagnostic confirmation was achieved . Exophtalmus was observed in the majority of cases and the inflamatory cause associated to sinusitis was the frequent followed by the augmentation of the falty tissue in the thyroid endocrinopathy. Among malignant processes, adult lymphoma, optic nerve glyoma and retinoblastoma in the child were found as the most frequent entities. Other processes observed were maxillary sinuses carcinoma, melanoma metastasis in adults and the rabdoyosarcoma in children. As well as osteoma, inflamatory pseudomotor, dermoid tumor, hematomas and arteriovenous fistula in adults, and infant osseous displasias. The helicoid tomography computed axial with multipolar reconstructions contributed to the diagnosis and space location and to the extension of process in all cases.
