[Significance of computed tomography in ophthalmologic diagnosis. II. CT of eyeball tumors, orbital tumors, nontumor space-occupying orbital processes and malformations].

CT is valuable to complete ultrasound findings in the evaluation of tumors of the eyeball. Tumoral and nontumoral space-occupying lesions and malformations of the orbit and the exact demarcation of these conditions within the periorbital structures are well demonstrated. In several different pathological conditions the CT appearances are often similar and only sometimes characteristic. Additional clinical data are helpful in giving hints for the diagnostic differentiation of the CT findings.
