Incidence of manifest squint among school children in Mansoura

ABSTRACT

Among 20,124 primary school children examined in the various primary schools in the Eastern district of Mansoura. We found 202 cases of Manifest Concomitant squint [2%]. The highest frequency of squint was at the age of six years [40.1%] and the incidence decreases during the school life to [7.9%] at the age of 12 years. The commonest type of deviation was the convergent type representing 84.1 of all cases. There is no significant difference between girls and boys in this work, as we found that the boys 102 [50.5%] and girls 100 [49.5%]. Most of the case with convergent squint were hypermetropic of moderate degree ranging from + 2.5 D. to 4.0 D. whereas in divergent squint 12 cases were hypermetropic and 20 cases were myopic
