[Multiple factor analysis of visual function in hypermetropic children].
OBJECTIVE
To investigate the characteristics of hypermetropic children whose visual acuity (VA) is declined or accompanied by esotropia.


METHODS
One hundred and ninety children were given optometry, strabismus degree and binocular vision measurement.


RESULTS
Declined VA appeared in 170 children, while esotropia occurred in 173. Sixty-one got binocular single vision, 17 had fusion function, and 11 had stereoaculty. Spherical equivalent had a linear relationship with VA (P < 0.01), but not with the strabismus degree (P > 0.05). The influence factors of binocular vision were age of discovery, VA and the strabismus degree, while the stereoaculty was influenced by the strabismus degree, spherical equivalent and VA.


CONCLUSIONS
Low VA and strabismus are the most common complaint in children. Ametropia and strabismus do great harm to juvenile binocular vision, and stereoaculty is damaged seriously. We suggest an early examination of visual function in children.
