Abstract
Abstract Purpose To compare the results obtained between Humphrey Perimeter (Carl Zeiss Meditec, EEUU) and Heidelberg Edge Perimeter (HEP, Heidelberg Engineering, Alemania) tested in a group of glaucomatous patients. Methods A total of 23 eyes of 23 glaucomatous patients were prospectively and consecutively selected. All of them had basal IOP values higher than 20 mmHg and glaucomatous optic nerve head. They were examined with Standard Automated Perimetry (SAP) using 24‐2 SITA standard and HEP perimetry using 24‐2 ASTA standard algorithm. They performed at least one reliable perimetry with each device. Spearman‘s correlation coefficients were calculated between global indices of both devices: mean deviation (MD), pattern standard deviation (PSD) and visual field index (VFI). Results Mean age was of 65.07±8.67 years. Subjects had mean IOP values of 24.43±1.90 mmHg. The mean MD values were ‐6.73±6.23 and ‐2.89±3.26 measured with Humphrey and HEP perimeters respectively. And the mean PSD values were 6.07±3.62 and 3.80±2.45 measured with Humphrey and HEP perimeters respectively. The strongest correlations were observed between MDs (0.683; p=0.001) and between PSDs (0.619; p=0.003). Conclusion Humphrey and HEP perimeter correlated well in some global values. Further studies are required to evaluate the clinical usefulness of HEP perimeter in glaucoma patients.
