Visual fields in a successfully radiated retinoblastoma patient.
1. Computerized visual fields have recently been used to study patients before and after treatment of choroidal melanoma with plaque therapy. Such information is unavailable for patients diagnosed with retinoblastoma. 2. There is no information on the long term visual fields of successfully treated retinoblastoma; therefore, no comparisons can be made between the effects of photocoagulation, cryotherapy, plaques, and external beam radiation on the visual field defects. 3. External beam radiation to tumors around the optic nerve caused widespread patchy sparing because of partial destruction of the nerve fiber layer. Whether the destruction was related to the position of the tumors or the effect of the radiation is unknown.
