Contribution of echography to the diagnosis of retinoblastoma: a homogeneous B-scan study.

This paper concerns the echographic study of 38 pathological eyes suspected to be retinoblastoma cases examined between 1980 and 1983. It was a homogeneous study carried out with the same machine (Biophysic Medical's Triscan) and the same operator. No error of diagnosis was made on the 25 eyes considered to be cases of retinoblastoma. Two doubtful cases turned out to be pseudogliomas and in eleven cases the diagnosis of pseudoglioma given by the echography examination turned out to be correct. This study helps to demonstrate the importance of echography in the diagnosis of retinoblastoma and in the differential diagnosis between retinoblastoma and pseudoglioma.
