Figure 1: (a) A well circumscribed amelanotic iris mass with prominent feeding vessels over the surface. (b) Initial UBM revealed a hypoechoic mass in the iris stroma with 3.6 mm horizontal diameter and 4.7 mm vertical diameter, in the absence of a visible peduncle. (c) The iris mass doubled in size within 2 months displacing the entire pupil superiorly. (d) Successive UBM at two months later disclosed a significant enlargement of the iris mass occupying 70 percent of anterior chamber volume.
