[Ultrasound biomicroscopy for evaluation of space-occupying lesions of the anterior eye segment. Initial results].

Pavlin's group developed the ultrasound biomicroscope, and it has been in use since 1990. It is an ultrasound method working at high frequencies between 40 and 100 MHz. It is possible to resolve structures up to approximately 50 microns in size at a maximal depth of 5 mm. We examined about 80 patients with tumors in the anterior segments of the eye, mainly in the iris and the ciliary body. Good differentiation between cystic and solid space-occupying lesions is possible to say whether or not is malignant.
