[Differential diagnosis of retinoblastoma and Coats' retinitis using computer-assisted processing of ultrasonographic scanograms of the eye].

A new method for quantitative evaluation of ultrasonic scanograms of the eye, that permits differentiation between retinoblastoma and Coats' retinitis, was employed in echographic examinations of the eyes in 21 children with suspected intraocular volumic processes. Image analysis by plotting and processing of histogram was employed. High-confidence differences in the 'excess' and 'skewness' meanings of gradient histograms of patients with these two conditions have been detected.
