ResumoI thank Dr. Weger and colleagues for their letter concerning my paper on “Hyperhomocysteinemia: A Risk Factor for Central Retinal Vein Occlusion.” I agree with them that a large number of variables can influence plasma homocysteine levels including medications, vitamin intake, age, sex, smoking, coffee consumption, serum cholesterol level, physical activity, etc. 1 Nygard O. Vollset S.E. Refsum H. et al. Total plasma homocysteine and cardiovascular risk profile. The Hordaland Homocysteine Study. J Am Med A. 1995; 274: 1526-1533 Crossref Scopus (1033) Google Scholar The role of the control group, of course, is to try to control these variables and other variables, which we may not be aware of.
