Ultrasonic Diagnosis of Tumors of the Choroid

Eye

“…79,80,82 The B-mode ultrasonographic appearance of canine anterior uveal (ciliary body) melanomas has been reported. 78 There do not appear to be any distinguishing B-mode characteristics of canine anterior uveal melanomas at this time, other than location and frequency of occurrence ( Figure 5-12). An acoustic quiet zone (internal shadowing) was not seen.…”

Multimodal Imaging in Choroidal Metastasis

“…However, the acoustic profile does not make it possible to differentiate the cytological characteristics of the lesions completely. The acoustic profile can be masked by structures that precede the tumour or by an incorrect alignment of the probe to the vitreous-tumour interface [20]. Typically, the choroidal metastases appear flat or plateau shaped, often associated with serous retinal detachment [7].…”

Conversion Factor for B‐Scan Ultrasound Measurement of Intraocular Tumors With and Without the Sclera

“…13 It can also be difficult to discern the line between the tumor border and the scleral echoes. 9 To avoid these errors, it is important that the examiner has experience and expertise in measuring intraocular tumors. 11 Moreover, different institutions may use varying techniques for tumor measurement.…”
