Purpose: This study aimed to investigate whether the use of the cross test with central fusion point instead of the pointer test is valid in the MKH test and its effectiveness.
Methods: A partially modified four-step MKH test was performed using three of the five basic indicators (cross test (K), pointer test (Z), and rectangle test (H)) for the MKH test and cross test with central fusion point. Statistical analysis, an independence test, was performed with SPSS 23.0.
Results: First step. The results of the independence test of the two indicators (p=0.613) showed that the cross-test with central fusion point could not be used as a substitute for the pointer test. Second step. The cross-test with central fusion point was not valid to be used as a substitute for the pointer test before and after the cross-test correction (pbefore=0.596, pafter=1.000). Third step. The cross test with central fusion point did not play any role as a substitute for the pointer test in two of the three subjects. Fourth step. In 10 of the 11 subjects, the cross test with central fusion point did not play any role as a substitute for the pointer test.
Conclusions: During the MKH examination, it was confirmed that the cross test with central fusion point could not serve as a substitute for the pointer test.
