[Stereoacuity and ametropia].
The stereoacuity threshold (ST) was measured in 124 cases of correctable ametropia, comprising 100 cases of myopia (-0.75 to -13.00D) and 24 cases of hyperopia (+0.87 to +5.00D). The mean ST in myopia without and with correction was 97.73" and 8.25" respectively and in hyperopia without and with correction was 21.37" and 9.74" respectively, both differing significantly from the value of 5.15" in normal eyes. The results indicated that the ametropia could have affected ST through reduced visual acuity and possibly other factors.
