To perform dark- and light-adapted (DA and LA) static perimetry on normal subjects and patients with acute zonal occult outer retinopathy (AZOOR).
Subjects were ten normal subjects and three patients with AZOOR. Static perimetry was performed using OctopusTM 101. DA static perimetry was done after 30-minute dark adaptation, and no background light was used during DA perimetry. LA perimetry was done after 10-minute light adaptation with background light of 32 cd/m2, and same background light was used during LA perimetry.
In the normal subjects, the fovea showed higher threshold than the parafoveal regions in DA static perimetry, and contrarily, the fovea showed lower threshold than the parafoveal regions in LA static perimetry. In the patients with AZOOR, large absolute scotoma was detected in LA static perimetry, and the scotoma however vanished in DA static perimetry.
In the patients with AZOOR, localized and selective cone dysfunction and normal rod function were observed in the lesion of the retina.
