Visualization of the position of an episcleral plaque in relation to the
underlying choroidal melanoma during the early radiation treatment period
reconfirms accurate plaque location and may help assure optimal treatment.
We used high-resolution B-scan echography to confirm the position of the
episcleral plaque in 16 consecutive cases of choroidal melanoma. The
technique is most useful for well-defined tumors as small as 3 mm in height
whose anterior border does not extend beyond the ora serrata.
