Relationship between Choroidal Thickness and Visual Field Impairment in Acute Zonal Occult Outer Retinopathy

Figure 3

Changes in choroidal thicknesses using EDI-OCT in eyes with AZOOR and unaffected fellow eyes. (a) In the AZOOR eyes (solid black line), the mean subfoveal choroidal thickness (SCT) was significantly reduced at 3 and 6 months compared with baseline (, for both), whereas it was unaltered in the unaffected fellow eyes (dotted line). (b) In the AZOOR eyes (solid black line), the mean choroidal thickness at the nasal site 1000 μm away from the subfovea was significantly reduced at 3 and 6 months compared with baseline (, for both), whereas it was unaltered in the unaffected fellow eyes (dotted line). (c) In the AZOOR eyes (solid black line), the mean choroidal thickness at temporal site 1000 μm away from the subfovea was significantly reduced at 3 and 6 months compared with baseline (, for both), whereas it was unaltered in the unaffected fellow eyes (dotted line). (d) Similarly, in the nontreated AZOOR eyes (solid black line), the SCT significantly decreased over time compared with baseline (, for both). In the corticosteroid-treated eyes, it showed the same trend (dotted line).
