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

Figure 2

Changes in average threshold on Humphrey perimetry in eyes with AZOOR and unaffected fellow eyes. The “average threshold” is defined as the average values of 4 threshold points surrounded by a red square shown in Figures 1(c) and 1(d) at the AZOOR lesion area. In the AZOOR eyes (solid black line), the mean average threshold was significantly higher at 3 and 6 months than at baseline (, , resp.), whereas it was unaltered in the fellow eyes (dotted line).
