[Computerized ultrasonic diagnosis of voluminous intraocular neoplasms].
A method of differential diagnostics of voluminous intraocular neoplasms is described; the method is based on the usage of serum-scale scanning, echodensitometry, and vector mode of narrow-strip amplitude filtration (a modification of A-scanning). The digital one-dimension scanning images were subjected to spectral analysis. The obtained results were used alongside with the echodensitometry parameters of echogenicity and homogeneicity as the input data for a subsequent discriminative analysis. A total of 100 scanning images, obtained from 50 patients (50 eyes), with voluminous intraocular neoplasms underwent such analysis: according to its results, the correct diagnosis was made in 97 of 100 cases.
