Answer
Answer
Ultrasound biomicroscopy (UBM) has the following advantages:
-
Provides excellent resolution for anterior ocular abnormalities
-
Can differentiate very anterior choroidal melanomas from those of ciliary body origin
-
Can help define the tumor’s anterior border
-
Is also helpful in assessing angle-closure glaucoma
