Objective: To describe the visual field defects in retinobl- astoma survivors and relate those defects to characteristics such as tumor siz e, tumor location, and treatment modality. Methods: Thirty-one patients treated for retinoblastoma were included in this study. Humphrey visual fields were det ermined in 33 eyes. Results: Twenty-seven patients (29 eyes, 68 tumors) had suf ficient diagnosis and treatment data available for further analysis. Twenty-six of the 27 patients had both absolute and relative visual field defects. Four ty pes of visual field defects were observed and correlated with location of the tu mor and therapy to the individual tumors: (1) no residual defect, (2) absolute s cotoma, (3) arcuate and sector scotoma, and (4) "pseudo"-visual field defects caused by relative enophthalmos resulting from radiation. Conclusions: Patients with retinoblastoma demonstrate a variety of long-term visual field defects af ter treatment for their intraocular disease. Characteristics that determine the size and type of defects are tumor size, tumor location, and treatment method.
