title: A new ultrasonic apparatus for ophthalmology using manuel compound scanning.
abstract: A new ultrasonic equipment for ophthalmological diagnosis has been developed. Manual compound scanning using water immersion made acurate representation of cross-section of the orbital structure possible. A large, focused transducer brought resolution and sensitivity. Gray scale display of the ultrasonogram increased information concerning intensity of echoes. Ultrasonograms of retinoblastoma, vitreous hemorrhage, melanocytoma, optic disc coloboma and unilateral exophthalmos are presented.
