Six cases of sector retinitis pigmentosa were studied by automated static perimetry and photopic electroretinogram. Four cases out of six revealed elevated thresholds in the lower half of the visual field, which correspond to the normally appearing upper eyeground. They also showed delayed implicit time on the photopic electroretinogram. These results show that sector retinitis pigmentosa is not necessarily a regional retinal dystrophy.
