Abstract
Senile cataract is most commonly type of cataract. Senile cataract patients are estimated to reach 90 % of all cases of cataracts. In patients with senile cataract change the balance of sodium and potassium aqueous humor. Aqueous humor derived from serum, and aqueous humor is an essential nutrient for the lens, the canging at serum concentration also affects the aqueous humor. To determine the accuracy levels of aqueous humor sodium and potassium with serum sodium and potassium levels in patients with senile cataract. A ddiagnostic test has been conducted in the Polyclinic of Dr Mohammad Hoesin Hospital and at Polyclinic of Eyes Hospital Palembang starting in March 2016 until June 2016.There were 30 samples of patients with senile cataract who meet the inclusion criteria. The frequency and distribution of data are described in tables and sensitivity and specificity values will be cut point (cut- off point) to determine levels of sodium and potassium aqueous humor with sodium and potassium serum by using ROC curve. Aaccuracy rate is measured by the value of Kappa . Data were analyzed by using SPSS version 18.0. Of 30 patients with senile cataract had a mean age of approximately 64 years with a sex ratio of men and women is 2 : 1 . The accuracy values obtained from sodium aqueous humor level and sodium serum levels in patients with senile cataract is 0.267 and the accuracy of potassium aqueous humor level with potassium serum levels in patients with senile cataract was 0.6. The aaccuracy of sodium aques humor with sodium serum levels in patients with senile cataract had a sensitivity 8.3 % ,followed by a specificity 100 % , positive predictive value ( PPV ) 100 % , negative predictive value ( NPV ) 21.4 % , a positive likelihood ratio and the ratio ∞ negative likelihood 0.917 while the accuracy of potassium aqueous humor with potassium serum levels in patients with senile cataract had a sensitivity 57.14 % , specificity 62.5 % , positive predictive value ( PPV ) 57.1 % , negative predictive value ( NPV ) 62.5 % , a positive likelihood ratio 1.523 and a negative likelihood ratio 0.686 in a row. It can be concluded that the accuracy of sodium aqueos humor with sodium serum levels in patients with senile cataract is slighty and accuracy of potassium aqueous humor with potassium serum levels in patients with senile cataract is moderate.
