Background:
This study aimed to discover the influence of the chronic diseases diabetes mellitus and arterial hypertension on color vision.
Methods:
The study included 96 voluntary participants age 19-65 years. They were divided into four groups. Group I consisted of patients with arterial hypertension; group II included those with both arterial hypertension and diabetes mellitus; those in group III had diabetes mellitus; and group IV consisted of healthy individuals.
Results:
The duration of diabetes in group II correlated with the Rayleigh calculation. Those in group III showed significant differences when the maximum brightness setting (Moreland) and the minimum anomalous quotient (Raleigh) were used. The duration of diabetes had correlations at some parameters of the Rayleigh and Moreland calculation.
Conclusion:
In conclusion, we are able to say that the all-color anomaloscope is useful for determining alterations in color vision in patients with diabetes mellitus.
