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 corresponded 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.
对6例扇形视网膜色素变性患者进行了自动静态视野计检查和明视视网膜电图检查。6例中有4例在视野下半部分阈值升高，这与眼底上半部分外观正常相对应。他们在明视视网膜电图上也显示出潜伏期延长。这些结果表明，扇形视网膜色素变性不一定是局限性视网膜营养不良。
