  Objectives: To find out whether there is a difference in measured values of visual fields at the same patients by two different perimeters. Methods and patients: The authors examined 40 eyes of 20 persons with hypertensive glaucoma in incipient stage (aged 14-77 years, mean 60 years) using the device Medmont M700 and Octopus 900. In both cases similar strategy and programs of examination for determining threshold sensitivity in decibels (dB) were used, namely at the device Medmont - the fast threshold, and at the Octopus - the TOP strategy (G standard). Measured values of mean sensitivity in dB and apostilbs (asb) were processed statistically. Since the data significantly deviated from a normal distribution, particularly in the case of asb, non-parametric Wilcoxon pair test was used.  Results: The authors proved hig.. View More»
