A comparison of the integrated dose (Gy) at different points of interests in an eyeball, implanted with a 16 mm eye plaque located next to the tumor on the equator temporal to the eyeball. Columns labeled “P.W” and “S.W” compares the dose for 13 125I seeds in water phantom with and without the presence of the plaque, respectively. “Eye” refers to simulated human eye using the data of Table 2 and “water” refers to the simulated human eye in which all parts of the eye were assumed to be made of water. “Plaque in eye” refers to the 13 125I seeds with plaque present in human eye phantom. “7 mg/g, 10 mg/g, 18 mg/g, and 30 mg/g” refer to the concentration of GNPs inside the tumor in both phantom types. The relative statistical uncertainty is lower than 1%
