Association between low plasma vitamin E concentration and progression of early cortical lens opacities.
The authors evaluated the association between plasma vitamin E content and progression of eye lens opacities. A total of 410 hypercholesterolemic eastern Finnish men participated in the study from January 1990 to September 1993 in Kuopio, Finland. Lens opacities were classified three times at 18-month intervals using the Lens Opacities Classification System II. A low plasma vitamin E level (lowest quartile) was associated with a 3.7-fold excess risk (95% confidence interval 1.2-11.8) of the progression of early cortical lens opacities compared with the highest quartile (p = 0.028). In addition, the number of cigarettes smoked daily was a significant predictor of the progression of cortical lens opacity (relative risk = 1.06 per cigarette, 95% confidence interval 1.003-1.12). The progression of nuclear lens opacities was not associated with either the plasma vitamin E content or smoking. The data suggest that low plasma vitamin E content may be associated with increased risk of the progression of early cortical lens opacity.
