| Summary: |
Purpose: 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. |
