[Ultrasonography of choroidal melanoma].

The authors discuss the use of standardized echography in the diagnosis of melanoma of the choroid. They mention the investigated acoustic criteria in images B and A (shape, size, limits, site, structure, reflectivity, weakening of the ultrasonic signal, vascularization, mobility, consistence) and their importance for more detailed identification of the tumour. Investigation of the acoustic properties of choroid melanoma and assessment of acoustic criteria for echographic assessment of choroid was based on echographic examination of a total of 109 bulbi where melanoma was confirmed also by histological examination.
