The tumor basal diameter is measured by funduscopy and fundus 30 Pe’er photography, preferably by using a wide-angle camera, and by B-scan ultrasonography. The tumor thickness is measured by A-scan, or, if not possible, by B-scan and high-frequency ultrasonography, or a combination thereof. The surgery for positioning the plaque over the treated tumor can be performed under either local or general anesthesia. A 360° or partial peritomy is used to expose the sclera in the tumor area. If the tumor is located under a rectus muscle insertion, the muscle should be disinserted after placing sutures to the muscle tendon and measuring the knot-to-limbus distance.
