Objective: Comparison of binocular functions in stabismic and anisometropic amblyopic cases.
Material and methods: Sixty patients were grouped as strabismic and anisometropic acording to amblyopia type. Fusion was evaluated with Worth 4 point and Bagolini test stereopsis with Randot and Titmus stereotest. In statistical analysis, Chi-square test, independent sample t test, crosstabs were used.
Results: There were strabismic amblyopia in 34 (56.6%) cases (Group 1) anisometropic amblyopia in 26 (43.4%) cases (Group 2). Mean age was 9.61 in strabismic amblyopes, 8.66 in anisometropic amblyopes (p=0.142). Mean corrected visual acuity was 0.49 in group 1, 0.51 in group 2 (p>0.05). Statistically significant difference was found in results of Worth 4 point test between two groups (p=0.0498). Statistically significant difference was not found in results of Bagolini test between two groups (p=0.139). While mean contour stereoacuity was 397.15 arc/seconds in anizometropic ambliyopes, 416.64 arc/seconds in strabismic ambliyopes (p=0.739). Mean randomdot patern stereoacuity was 394.23 arc/seconds in anisometropic ambliyopes and 418.51 arc/seconds in strabismic ambliyopes (p=0.483). There was no statistical significant difference in these results between two groups.
Conclusion: Fusion was found to be beter in anisometropic amblyopia than strabismic amblyopia. There was no statistically significant difference in stereopsis level between two groups. We thought that this may be related to no difference in mean of visual acuity, age between two groups. |
