[Role of astigmatism in the creation of myopia].
OBJECTIVE
To determine, whether the presence of astigmatism has an influence on the creation of myopia.


METHODS
A total of 167 people with myopia (117 women and 50 men) of the age between 12 and 51 were examined. The overall average age was 24. Routine ophthalmological examinations, keratometry as well as refractometry were carried out. The data was analysed using the coefficient of rang Spearman's correlation and the coefficient of linear Pearson's correlation.


RESULTS
A negative correlation was found between the corneal astigmatism and myopia progress (P < 0.000001). A positive correlation was observed between total astigmatism and myopia (P < 0.000001).


CONCLUSIONS
Corneal and total astigmatism predisposes the progress of myopia.
