[The criteria for echographic diagnosis in retinoblastoma]

The paper present an echographic survey on 27 pathological eyes suspected to present retinoblastoma, investigated with the same devices and by the same investigator. The diagnosis of retinoblastoma has been echographically put on 13 eyes. We haven't noticed any error on the investigated set since the diagnosis was histopathologically confirmed on 11 eyes. 2 eyes were not enucleated because they had before the enucleation of the contralateral ocular globe. It is discussed the utility of the echographic investigation for the positive and differential diagnosis of the retinoblastoma.
