[Investigation on traditional Chinese medicine and Western medicine susceptible factors on senile cataract].

In 743 cases, the TCM and WM susceptible factors of senile cataract (SC) was studied by the clinical epidemiological investigation. By single factor analysis, the result showed that in WM, the susceptible factors of SC mostly related to (1) case history: coronary heart disease, old ages, smoking, multiple offsprings; (2) physical sign: short build, with coronary sulcus, higher systolic pressure, pulse pressure and average arterial pressure; (3) cardiovascular function: abnormal EKG, higher heart beat index, short microcirculatory stasis time, lower carrier viscosity of blood; (4) dysfunction of brain; (5) deficiency of pulmonary function; (6) lower RBC ATPase, higher whole blood reduction viscosity. While in TCM, it was related to (1) old aged and general asthenia, (2) deficiency of Qi, Heart, Liver or Kidney, (3) Blood Stasis. By stepwise regression analysis, the result showed that SC occurred through the combination with 13 factors of TCM and WM, including Yin Deficiency, senility index, hemorheology index, brain function, pulmonary function, blood pressure, body height, character, optical fundus, etc.
