[Radiation cataract following injection of radium 224].
The Spiess Ra-224 series ist presented. It consists of 900 patients who were repeatedly injected intravenously with known dosages (microCi/kg) of the alpha-particle emitter Ra-224 for the intended treatment of tuberculosis and ankylosing spondylitis between 1943 and 1952/1965. 682 patients had been treated as adults after the age of 20 years, and 218 hat been injected as "juveniles" aged 20 years or younger. All 218 "juvenile" patients except one who had suffered from ankylosing spondylitis, had been injected for tuberculosis. Among the 218 patients 91 have died leaving 127 alive. Of the "juvenile" patients 9 were examined at the Eye Hospital of the Universität München including histopathology of an autopsy eye in one case. Of the 9 patients 8 proved to have some cataracts and 2 appeared morphologically similar to age-related cataract. In 6 patients there was a posterior subcapsular cataract which was a dense round plaque with a clear subcapsular zone of about 0.5 to 0.6 mm. This clear zone corresponds well to newly deposited lens fibres during the period of about 40 years from treatment to examination.
