case_images: In March 2022, the 78-year-old man was seen with a complaint of a "brown spot on his right eye that was enlarging in size." Examination revealed a darkly pigmented, anterior chamber tumor present in the superior nasal quadrant of the iris with neovascularization in the right eye (Fig. 1 left). MRI demonstrated the iris area of the right eye tumor mass by size approx. 6 x 3 mm, dorsally pressing on the lens and laterally on the ciliary muscles (Fig. 1, right), without clinical signs of extrabulbar growth.
case_images: Left: stereotactic irradiation scheme by LINAC 1-day surgery; TD was 20.0 Gy in the tumor (red color). Right: stereotactic irradiation scheme by LINAC 1-day surgery - sagittal view; TD was 20.0 Gy in the tumor, TD max 22.0 Gy (red color).
