[Acoustic investigations in orbital tumor diagnosis (author's transl)].
360 patients with unilateral exophthalmos were examined with echoophthalmograph to study the diagnostical possibilities of a method of echography in orbital tumors. The findings of para- and transbulbal methodics were checked in 140 patients. The tonometry of tumors and soft orbital tissues was performed. The methodics of acoustic orbitonometry based on the measurement of retrobulbal neoplasms at the moment of their step-by-step compression was worked out. The echographic symptoms of different orbital neoplasms is described as well as those of pseudotumor and tireotropic exophthalmos. The possibility of acoustic measurement of orbital neoplasms is shown. The dependence between the extent and progress of deformation in the exophthalmed eye on one hand-nature of exophthalmos, character and localization of the tumor on the other was revealed. The quantitative data about the compression of different orbital tumors were obtained. It was shown that the surveying echography, biometry and acoustic orbitonometry facilitate the task of differential diagnosis, allow the localization and size of the tumor to be detected and help to control the results of the treatment.
