Prevalence of lens changes in ukrainian children residing around Chernobyl.
The objective of this study is to determine the prevalence and characteristics of lens changes in the eyes of a pediatric population, 5-17 y old, living in the permanent control zone around the Chernobyl nuclear reactor and to compare these findings with those from an unexposed control population.
A total of 1,787 children are reported on (996 exposed and 791 unexposed).
Over three-quarters of the subjects examined in this study show a form of minor change, termed focal lens defect, in the cortical and/or nuclear portions of the lens of the eye.
The exposed group shows a small (3.6%), but statistically significant excess (p=0.0005) of subclinical posterior subcapsular lens changes similar in form to changes identified in atomic bomb survivors.
These posterior subcapsular changes tend to occur in boys 12-17 y old and in exposed children who report consuming locally grown mushrooms on a regular basis.
