[Christmas tree ornament cataract--an indication for disordered lipid metabolism?].

Cataract combined with Christmas tree decoration crystals in the lens is a relatively rare but very impressing cataract formation. The aim of this controlled study was to give an answer to the question, whether cholesterol level in blood is as important for local cholesterol accumulation in the lens as it is for the mechanism of arteriosclerosis. The blood levels of cholesterol, triglyceride, HDL and LDL were examined in 35 patients (average age 83.5 years; 26 women, 9 men). There was no significant difference between these parameters and those of a control group, which is similar in age and sex proportion. Therefore it is presumed, that these crystals of cholesterol are a result of lens metabolism and not of hypercholesterolemia.
