The mean age was 55.09 ± 15 years’ .In cases 69 (78.7%) Oblique, 64 (34.2%) With the rule and 45 (24.1%) Against the rule .In the healthy group, were 38 %, 45.4%, 16.7%. There was no significant correlation between the types of astigmatism in the two groups (p = 0.12). The severity of astigmatism in all three types was significantly different in two groups. There is a significant difference between the mean of astigmatism and the size of Pterygium (p <0.001)

Conclusions:
