Discrepancy in Subfoveal Choroidal Thickness in Healthy Adults with Isometropia

With the introduction of enhanced depth imaging optical coherence tomography (OCT), there have been a few studies investigating interocular differences in choroidal thickness.1–4 Previous studies have demonstrated interocular symmetry of choroidal thickness, and interocular difference seems to be correlated with interocular difference of axial length in adults1,2 and children.3
