. Twenty‐four eyes from 18 patients cured for retinoblastoma by radiation on an average 12 years previously, were re‐examined with respect to visual performance. The macular functions, i.e. visual acuity, colour vision and contrast sensitivity demonstrated performances predictable from tumour localization and radiation dose to the macula. The rod functions, i.e. visual field and dark adaptation were found to be relatively resistant to the radiation treatment. A special problem encountered in two‐eyed patients was the unavoidable amblyopia due to unequal handicaps in the two eyes at the vulnerable age.
