Introduction
To estimate the objective and repeatable method for measurements of the retinal vessels' diameter. The direct reason for creating this method was to use it to evaluate the influence of a exogenous estrogenes on a retinal blood vessels. Material and methods Basing on a modern computer systems, using funduscamera Canon NF 505, the model of active matrix for repeatible method for estimating the changes in vessels' diameter, was elaborated. Results After statistical analysis of a material of 3000 measurements, the degree of objectiveness and recurrence and the potential scale for errors was acknowledged. This method enables the estimation of the changes in retinal vessels diameter caused by many different factors in comparison to initial observations (set as 100%) in every analysed case. Conclusions Presented method can be succesfuly used for objective, reliable evaluation of changes in the blood vessels diameter caused by many different factors. keywords:
