CONVENTIONAL DIAGNOSTIC ULTRASOUND OF IRIS LESIONS

Eighty patients, referred for further evaluation of prominent iris les ions, were examined with conventional B-mode ultrasound equipment comb ined with a simplified immersion technique. The axial resolution of th is system is about 350 microns. In 20.3% of the cases, the lesion was too small for ultrasound detection. A cystic lesion was diagnosed in 2 6% and a solid lesion in 53.7% of the patients studied. In 33.4% of th e cases, the lesions were not confined to the iris but also appeared i n the ciliary body. This last result shows the diagnostic value of the conventional ultrasound examination in the evaluation apparent iris l esions.
