 | This is Gordon Isaacs, the first patient treated with the linear accelerator (radiation therapy) for retinoblastoma in 1957. Gordon's right eye was removed January 11, 1957 because the cancer had spread. His left eye, however, had only a localized tumor that prompted Henry Kaplan to try to treat it with the electron beam. Gordon is now living in the east bay, and his vision in the left eye is normal.Credit: Unknown photographer/artist. |  | (20) color slides. (14) 8x10 color prints, (1) 8x10 black and white print.

Health | Retinoblastoma is a rare cancer of the eye. It may be hereditary, and one-third of the cases involve both eyes. Retinoblastoma often can be seen by looking at the young person's eye but is usually diagnosed by an examination under general anesthesia using an ophthalmoscope, an instrument used in examining the interior of the eye. The disease tends to remain localized for long periods, but in advanced stages, it can metastasize, or spread to other parts of the body. x-rays, bone marrow examination, MRI, and a bone scan can be done to check for metastases.
