• Standardized A-scan echography (ultrasonography) is rapidly assuming its appropriate role as a primary diagnostic tool in ophthalmology. Its ability to display "tissue texture" can be used by the experienced examiner to establish a reliable tissue diagnosis in a high percentage of lesions. The most important intraocular neoplasm is the choroidal malignant melanoma, and a diagnostic accuracy in excess of 95% has been reported by Ossoinig et al. This smaller series of proven choroidal malignant melanomas diagnosed preoperatively by standardized A-scan confirms the reliability of this noninvasive technique.
