[Computer tomography of the eye and the orbit (author's transl)].
Princips of computer tomography is demonstrated and the absorption coefficients of ocular and orbital tissue are calculated. The advantages and disadvantages of this procedure are discussed. 39 patients with ocular and orbital diseases were examined by computer tomography. The main indication was tumors, including metastases and diseases arising from ethmoidal cells. Vascular anomalies and tumors were better demonstrated by angiography. Dislocated lens, enlarged tumors of the choroid and prostheses (cerclage and orbital implants) are demonstrable. In contrast to echography, the computer tomography gives certainly better results in the posterior part of the orbit. Technical improvement of the apparatus could lead to a wider use in ophthalmology.
