Radiation Cataract—New Evidence on Radiation Dosage to the Lens

The British Journal of Radiology, 1966
1. The eyes of 104 patients treated for 106 tumours of the eyelids in 1952–53 and 1957–58, have been examined in 1964. 2. Fourteen cases of radiation cataract (only six seriously affecting visual acuity) were found in 38 patients treated by radon gold seed implant.
