Ultrasonography (echography) is a valuable diagnostic modality in ophthalmology. Its use in the detection and differentiation of intraocular and orbital diseases is expanding. B-scan provides cross-sectional display of diseased tissues and is valuable in detecting unsuspected disease. Quantitative A-scan is capable of demonstrating the internal texture of lesions, and this capacity coupled with the physician's familiarity with the histologic appearance of certain intraocular lesions often can lead to an accurate tissue diagnosis or can identify a group of possible diagnoses.
超声检查（回波描记术）在眼科是一种有价值的诊断方法。其在眼内和眼眶疾病的检测与鉴别中的应用正在不断扩展。B超扫描可提供病变组织的横断面显示，在检测未被怀疑的疾病方面很有价值。定量A超扫描能够显示病变的内部结构，这种能力加上医生对某些眼内病变组织学表现的熟悉程度，常常可以得出准确的组织诊断，或者确定一组可能的诊断。
