Objective

The authors establish dyschromatopsy in blue axes in glaucoma. An investigation interrelationship into early primary open angle glaucoma (POAG) and Color vision defects.

Methods

This study was performed in 24 patients (48 eyes) divided into 2 groups. 1st group: 12 patients (24eyes) whit early POAG and second control group 12 patients (24 eyes) were examined with the All-color anomaloscope and HUE-28 color screening test. In all cases both the red-green equation of Rayleigh and the blue-green equation of Morelend wertested and three variables where determined setting range (SR), calculated mid point (CMP) and anomalous quotient (AQ) as compared to control group.

Results

In the group POAG we establish in the blue-green equation SR was significantly enlarged. CMP was significantly shifted toward the short wavelength. HUE-28 test established 16 eyes (66,6%) and confirmed the predominance of blue-yellow dyshromatopsia axes in POAG.

Our results show diminution of the color discriminating sensitivity in the short wavelength, half of the visible spectrum and diminution of the blue cone sensitivity in POAG (p<0,001), no significant changes of the Rayleigh equation.

Conclusions

Additional test in the diagnosis of early POAG is blue-green color vision testing, with the all-anomaloscope-IF-2. The authors conclude that blue-yellow dyschromatopsia axes is predominant in early POAG with HUE-28 test.
