“…We have made use, for a time of dver 3 years, of echograms registered by an ultrasonic equipment both in experimental researches (3, 4, 5 ) and for diagnosing various diseases of the eye, such as intrabulbar tumours (1,6,8,9), intrabulbar foreign bodies (1, 6, lo), detachment of retina (1, I I ) , detachment of the choroid ( 7 ) , rupture of the sclera (2) and opacities of the vitreous (12). The echogram proved itself to be of such great use clinically, that a diagnostic examination by ultrasound has become in these 3 years a routine examination of the foregoing diseases at our Ophthalmic Department.…”
