Purpose: The purpose of the study was to compare the mean sodium andpotassium levels in patients with senile cataract and age-matched normalindividuals in Kashmir.Material and Methods: The study was designed as cross sectionalobservational study. 200 senile cataract patients scheduled for cataract surgeryin the Department of Ophthalmology and 200 individuals of the same age groupwithout cataract were selected. Mean serum sodium and potassium levels in thesenile cataract group were calculated and compared with the control group.Serum sodium and potassium levels were measured by flame photometrytechnique. Statistical software SPSS-16 was used and means were comparedbetween two groups by t-test. Since the study was a non interventional one,clearance was given by the department and study abides by the guidelines laidin the declaration of Helsinksi.Results: Mean serum sodium level in senile cataract patients and normalindividuals was 139.60 ± 5.23 mEq/L and 137.15 ± 2.93 mEq/L respectively andthere was statistically significant difference (p < 0.0001). Mean serum potassiumlevel in senile cataract patients and normal individuals was 4.35 ± 0.574 mEq/Land 4.31 ± 0.45 mEq/L, and the difference was not statistically significant (p =0.60).Conclusion: Serum sodium level in senile cataract patient was higher ascompared to the control group. This outcome might suggest that increaseddietary intake of the sodium leads to higher levels of serum sodium which in turninfluences the cataractogenesis in senile patients.Keywords: Cataract, risk factors, sodium, dietary.
