case_images: At the B-scan the lesion had a maximum thickness of 4.6 mm (Fig. 1).
case_images: Reconstructed computed tomography sagittal section and the relative stereotactic radiosurgery dose distribution; the visible contoured structures are the lens (yellow, top), the anterior chamber (light blue), the whole right eye (grey), the previously irradiated volume (yellow, bottom), the body profile (white), the brain (dark blue), the clinical target volume (green), the restricted planned target volume (PTV) to 27 Gy (red), and the PTV portion irradiated to 20 Gy (dark red). Percentage dose is shown in colour wash modality, from the local maximum of 101.2% (hottest colour) to 10% (coldest colour)

case_images: The planning doses to critical structures were below 8 Gy for the optic nerve and the optic disc, and 10 Gy for the eyelids and anterior segment of the eye (Fig. 2).
case_images: Stereotactic radiosurgery irradiation pattern with volumetric modulated arc therapy and rapid arc technique. The external body surface and major organs at risk have been reconstructed, and the photon beam intensity along each arc is reported (red bins)
