RESUMEN
To estimate change of blood constituents in cataract patients, the authors retrospectively reviewed medical records of catatract and non-cataract patients.We selected 199 pairs of cataract and non-cataract patients matched in age and sex.We compared the presence of diabetes, hepatitis B antigen and hepatitis C antibody, also other blood chemistry values between cataract and non-cataract patients group and also between cortical and noncortical patients group. Results are as follows:In cataract patients group, ALP (alkaline phosphatase) albumin/total protein-albumin ratio and K (potassium)were higher, and Na (sodium), total biilrubin and total protein were lower than in non-cataract patients.And in cortical cataract patients, AST (aspartate aminotransferase), BUN (Blood Urea Nitrogen), total calcium, Cr (creatinine), K and Cl (chloride) were higher and albumin/total protein-albumin ratio was lower than in noncortical cataract patietns.
