摘要

During the nuclear accident of Chernobyl in April 1986 numerous reactor workers and fire fighters were exposed to large doses of ionizing radiation. In addition to high ambient γ-ray exposures, these men suffered from a very inhomogenous contamination with fission products on their wet and insufficiently protective clothing, and a resulting severe exposure of the skin, predominantly with β-rays. 16 Chernobyl clean-up workers and 4 persons exposed during nuclear accidents at other nuclear installations were repeatedly examined between September 1991 and September 1996. The radiation exposures ranged from 0.35 to 9 Gy, according to data notified by GUS authorities. They were, in their general trend, confirmed by the determination of chromosome aberrations. The medical therapeutic measures were focused on orthopedic prosthetics and the treatment of chronic radiation dermatitis. Ophthalmological examinations included biomicroscopy of the anterior and ophthalmoscopy of the posterior eye segments. Quantitative assessment of ocular radiation damage, especially to the lens and the documentation of subsequent development of cataract was achieved by application of an electronic Scheimpflug camera system (Topcon SL-45, modified) that included image analysis for quantification of lens opacities. 2 patients had already undergone cataract extraction at first presentation, posterior subcapsular lens opacities were seen in 6 patients, 1 patient presented dense corticonuclear cataracts and pseudoexfoliation-like changes. 4 patients had chronic dry eye syndrome (reduced tear production in Schirmer test). Retinal radiation damages were not detected. No ocular radiation injuries were detected in 9 patients. Posterior subcapsular cataracts were found to be the predominant consequence of ocular radiation exposure in our patients. There is, at this point, no distinct correlation of ocular findings with the distribution and level of chronic cutaneous radiation damage or with the whole body doses.
