Ab interno resection technique. (A). First, phacoemulsification cataract surgery is performed. (B). Mushroom-shaped choroidal melanoma located on the superior temporal arcade with extensive retinal detachment. (C). Liquid perfuorocarbon is injected to flatten the retina. (D). Endophotocoagulation is performed around the tumour. (E). Resection is initiated by introducing the vitrectomy probe into the tumour. A low cutting rate and high aspiration is programmed, and the tumour is fragmented into pieces and aspirated. (F,G). The resection is completed until the bare sclera is reached. It is possible to leave a remnant since it will be treated by brachytherapy. (H). Perfluorocarbon liquid is then exchanged for silicone. At this stage, a hemorrhage may occur, which overlies the coloboma. Finally, a radioactive plaque is placed at the base of the tumour.
