Abnormal Outer Choroidal Vasculature in Amblyopia

Figure 2

Scatter plot of the choroidal vascular area in amblyopic, fellow, and control eyes. (a) The outer choroidal vascular area both in amblyopic (61.49 ± 4.95%) and fellow (61.48 ± 3.73%) eyes is markedly larger than that in healthy eyes (55.69 ± 1.83%; both ). When the cutoff value for the outer choroidal vascular area was set at 59%, we could distinguish between the amblyopic and healthy eyes with a specificity of 100% and sensitivity of 64% and between the fellow and healthy eyes with a specificity of 100% and sensitivity of 86%. (b) The inner choroidal vascular area did not differ among amblyopic (56.35 ± 2.46%), fellow (56.27 ± 3.75%), and healthy (55.73 ± 2.04%) eyes.
