Fluorescein angiography and light microscopy studies of retinas irradiated by oxygen nuclei.

Fluorescein angiography and light microscopy techniques were utilized in the rhesus monkey to evaluate retinal damage following oxygen ion irradiation. Particle flux ranged from 1.3 x 10(7) particles/cm2 to 1.5 x 10(8) particles/cm2. Earliest evidence of damage was detected with fluorescein angiograms 24 h after exposures to 7.7 x 10(7) particles/cm2. No evidence of the hypothesized microlesion was found by either technique.

Relative biological effectiveness (RBE) of heavy ions (O+8) for producing retinal lesions.

The relative biological effectiveness (RBE) for oxygen ions (250 MeV/nucleon) for producing an ischemic retinal lesion in the rhesus monkey has been shown to be greater than 10. The RBE concept and the use of the standard methodology is discussed with respect to other published reports.

Heavy-ion-induced cataractogenesis.

Cataract formation following heavy ion exposure (O+8) was noted in three rhesus monkeys secondary to a study of retinal effects. The pathogenesis of these lens changes follows many, but not all, of the characteristics for "radiation cataracts." The ring-shaped opacity was not noted to occur. Posterior capsular changes were noted initially and followed through the formation of a mature cataract.
