AIM:To investigate the stereoscopic vision and its damage in children with different types of amblyopia, in order to improve the curative ratio of amblyopia in clinic.

METHODS: Totally 321 children with different types of amblyopia from Hunan Children's Hospital were enrolled in this study. Distance stereoacuity was examined with synoptophore and random dot stereogram. Approximation zero disparity, crossed disparity and uncrossed disparity were examined with Yan's stereogram. All the datum were statistically analyzed.

RESULTS: The differences of approximation zero disparity, crossed disparity, uncrossed disparity and distance stereoacuity among each type of amblyopia group was statistically significant(P<0.05). The prevalence of stereopsis in strabismic amblyopia group and form-deprivation amblyopia group was lowest, but there was no significant difference between the two groups(P>0.05). The prevalence of stereopsis in ametropic amblyopia group was highest, and that in anisometropic amblyopia group was inferior.

CONCLUSION: All types of amblyopia can affect the development of stereoacuity in children. Strabismic amblyopia and form-deprivation amblyopia makes the greatest impact on children's stereoacuity; while the ametropic amblyopia makes the smallest impact on children's stereoacuity. The key to consolidate the curative effect of amblyopia is to pay attention on re-building the stereopsis.
