视网膜色素变性(RP)患者(268只眼)以近视屈光不正为主。虽然12%的正常人群有近视屈光，但在268眼RP患者中有75%的人近视，在X连锁RP患者的41眼中有95%的人近视。球面误差呈单峰偏态分布，平均屈光度为-1.86D，比正常人群明显(P<；0.001)近视-2.93D。X连锁遗传组的球面平均值为-5.51D，比非X连锁RP群体的近视显著(P<；0.01)。该X链接球面误差分布可以由两个单独的子分布组成。散光屈光不正超过0.5D的比例为47%，远高于正常人群的19%。
A retinitis pigmentosa (RP) population (268 eyes) had predominantly myopic refractive errors. Whereas 12% of a normal population have myopic refractions, myopia was found in 75% of 268 eyes of RP patients and in 95% of 41 eyes of X-linked RP patients. The spherical errors described a single-peaked, skewed distribution, with a mean of -1.86 diopters (D) that was significantly (P < 0.001) more myopic, by -2.93 D, than that of a normal population. The X-linked genetic group has a spherical mean of -5.51 D that was significantly (P < 0.01) more myopic than the non-X-linked RP population. This X-linked spherical error distribution may be composed of 2 separate subdistributions. Astigmatic refractive errors greater than 0.5 D were found in 47% of this RP population, considerably in excess of the 19% of a normal population with such astigmatic errors.
