Absolute vision thresholds were measured along the horizontal and vertical meridians in four patients from one pedigree and one patient from a second pedigree with dominantly inherited sector retinitis pigmentosa. From these studies we find that (1) visual function is decreased for all parts of the retina, including the fovea, (2) rod and cone systems are affected to the same degree, and (3) the disease progression is confined to the inferior portion of the retina.
对来自一个家系的4名患者以及来自另一个家系的1名患有显性遗传性扇形视网膜色素变性的患者，沿水平和垂直子午线测量了绝对视力阈值。从这些研究中我们发现：（1）包括中央凹在内的视网膜所有部位的视觉功能均下降；（2）视杆和视锥系统受到同等程度的影响；（3）疾病进展局限于视网膜的下部。
