The Evaluation of HRTII in Screening of Glaucoma with Different Discrimiant Formulas in Koreans

ABSTRACT

PURPOSE: To find the optimal discrimiant formula of HRTII program in detection of glaucoma in Korean patients. METHODS: The objects of this study were 421 eyes of 225 patients at Kangnam St. Mary's Hospital from December in 2002 to February in 2003. Humphery automated perimetry, program C24-2 testing, and HRTII (Software IP1-V1.6) were performed. The results were analyzed with Moorfields discrimiant formula, Mikelberg discrimiant formula and Park discrimiant formula. RESULTS: In 421 eyes, the number of glaucomatous eyes was 214. The accuracy of Moorfields discrimiant formula was 71.25%, its sensitivity was 72.42%, and its specificity was 70.04%, The accuracy of Mikelberg discrimiant formula was 71.49%, its sensitivity was 71.96%, and its specificity was 71.01%, The accuracy of Park discrimiant formula was 72.92%, its sensitivity was 73.31%, and its specificity was 72.46%. CONCLUSIONS: Park discrimiant formula was expected to be useful in the screenning of glaucoma in Korean patients.
