Abstract

we investigated the effect of spherical lens-induced anisometropia on dynamic stereoacuity. Twenty subjects with normal binocular function without past ophthalmic disease history were examined for the effect of anisometropia on the viasual acuity, static and dynamic stereoacuity created with spherical lenses in 0.5D stepwise manner before dominant eye from -2.0D to +2.0D. Dynamic stereoacuity was measured by new computer program. And we investigated the effect of anisometropia on dynamic stereoacuity as the power of the lenses was increased and the effect of plus lens vs minus lens on the dynamic stereoacuity. As a result, dynamic stereoacuity decreased statistically significantly as the power of the spherical lenses increased. And the plus 1.5D and 2.0D lens showed more deteriorating effects on dynamic stereoacuity than the corresponding minus power lenses, respectively. No statistically significant correlation was found between static and dynamic stereoacuity at each spherical lens diopter.
