To report undescribed characteristics of patients with bilateral diffuse uveal melanocytic proliferation (BDUMP) on ultrasound biomicroscopy (UBM) and high-frequency B-scan ultrasonography.


 All patients had ciliary body nevi-like lesion in combination with iris or ciliary body cysts, and uveal thickening on UBM.  Our case series demonstrates the uveal characteristics of patients with BDUMP based on high-frequency B-scan ultrasonography and UBM.
