Age-related cataract: a cross-sectional population-based case-control study of blood glucose and blood pressure

Cataract is opacity of the crystalline lens. The greatest risk factor for cataract formation is age. Diabetes mellitus is associated with incidence of cortical and posterior sub-capsular cataract. The association between age- related cataracts and systemic cardiovascular or atherosclerotic disease is reported in the recent epidemiologic reports. The search for these factors remains are primarily because theories of pathogenesis and prevention remain controversial. An observational population-based case-control study with 30 cluster-samples in order to analyze the relationship of blood glucose and blood pressure between cataract and no cataract patients who were 50 years or older was carried. The results of this study showed: The level of blood glucose is lower 6.1mmol/l associated with blood pressure is lower 140/90mmHg in cataract patients who were 50 years or older was unrelated. The relationship of blood glucose ³ 6.1mmol/l associated with blood pressure³ 140/90mmHg in cataract patients who were 50 years or older has a significant difference in statistics (OR=2.1 [1-4.3], p < 0.05).
Purposes: To study on the relationship of blood glucose and blood pressure on cataract patients who were 50 years or older
Design- Method: An observational population-based case-control study with cross-sectional 30 cluster-samples in order to analyze the relationship of blood glucose and blood pressure between cataract and no cataract patients who were 50 years or older was carried out in population.
Results: The level of blood glucose is lower 6.1mmol/l associated with blood pressure is lower 140/90mmHg in cataract patients who were 50 years or older was unrelated.
The relationship of blood glucose  6.1mmol/l associated with blood pressure  140/90mmHg in cataract patients who were 50 years or older has a significant difference in statistics (OR=2.1 [1-4.3], p=0.04).
Conclusion: Level of blood glucose  6.1mmol/l associated with blood pressure  140/90mmHg was related in cataract subjects who were 50 years or older.
This may also have a preventive utility, can be primarily manipulated these risk factors by general practitioners in detecting early onset retinopathy. For eye doctors, this finding may be a marker of parameters for follow-up the progression of cataract in ophthalmic practice.
