[Echography in the diagnosis of retinoblastoma].
Echography was performed on 38 eyes enucleated for suspected retinoblastoma. The two major criteria for the echographic diagnosis of retinoblastoma were the presence of intratumoral calcifications and normal axial length of the eye with respect to age. No errors in diagnosis were made on the 25 eyes considered to be cases of retinoblastoma by echographic criteria. Two doubtful cases turned out to be pseudogliomas and in 11 cases the diagnosis of pseudoglioma by ultrasonic examination was confirmed by histopathology. The results are compared with those of 67 cases of retinoblastoma examined from 1964 to 1977 by one of the authors and to other published series. This study helps to demonstrate the importance of echography in the diagnosis of retinoblastoma and in the differentiation between retinoblastoma and pseudoglioma .
