Anterior Segment Imaging in Ocular Surface Squamous Neoplasia

Figure 2

20 MHz transverse (a) and longitudinal (b) ultrasound biomicroscopy sections of conjunctival intraepithelial neoplasia demonstrate hyperechoic tumor surface (arrows) and hypoechoic stroma. (c) 20 MHz UBM image taken from a patient with squamous cell carcinoma demonstrates blunting of the anterior chamber angle (arrow) which correlated to anterior chamber angle invasion on histopathology [11].
