Researchers from the Eye Institute, University of Hong Kong reported that serum cholesterol level might influence individuals’ choroidal thickness. A total of 322 eyes of 161 subjects have been studied. Subjects were divided into those with hypercholesterolemia and normal control subjects. The subfoveal choroidal thickness was found to be significantly higher in subjects with hypercholesterolemia. The investigators stressed that this has to be taken into account when analyzing choroidal thickness.
