Abstract
Purpose:
To investigate the relationship between subfoveal choroidal thickness and axial length in both eyes of preschool children with hyperopic anisometropic amblyopia.
Methods:
Thirteen patients with hyperopic anisometropic amblyopia between the age of 3 and 6 were examined. Differences of the spherical equivalent between both eyes were over 1.5D. Subfoveal choroidal thickness was measured using enhanced depth imaging optical coherence tomography, and axial length was measured using noncontact optical biometer.
Results:
The spherical equivalent in amblyopic eyes ranged from +3.50 to +6.50D and that in normal fellow eyes ranged from +0.75 to +3.50D. The subfoveal choroidal thickness in amblyopic eyes was significantly greater than that in normal fellow eyes (414.69±13.15μm vs. 377.00±15.12μm, Wilcoxon signed-rank test, p < 0.01). The axial length in amblyopic eyes was significantly shorter than that in normal fellow eyes (21.31±0.18mm vs. 22.14±0.22mm, Wilcoxon signed-rank test, p < 0.01). Moderate negative correlation was found between the subfoveal choroidal thickness and the axial length (R=0.52, p<0.01).
Conclusions:
The choroidal thickness was associated with the axial length in hyperopic anisometropic amblyopia. We considered that the subfoveal choroidal thicknesses in the amblyopic eyes reflect the delays of emmetropization.
