正视眼

Objective:Since some limitaions of SRK Ⅱ formula,the dual cubic curved regressive formula was designed. methods:By means of computer,statistical analysis and regressive treatment of kerato diopter,axial length and emmetropic IOL diopter of 415 pseudophakia was done.

针对目前临床上常用的SRKⅡ公式在计算人工晶体屈光度时的局限性，对415只后房型人工晶体眼的角膜屈光力、眼轴长度和正视化人工晶体屈光度进行回归分析后，设计出一种不同于传统的线性回归公式的曲线回归公式——二元三次计算公式。

Methods Fourty subjects, 20 anisometrope and 20 emmetrope, the AMP accommodation lag and NRA/PRA were measured after the distance refractive correction.

选取40位受试者，正视者右眼20只，屈光参差者20位，其中屈光参差者高度数眼20只，屈光参差者低度数眼20只，在屈光完全矫正的基础上用主观的测量方法测量其调节幅度、正负相对调节和调节滞后量。

Results The axial length of eyeball was gradually decreased during the adult years of life accompanying with the increases of corneal and lens refractive powers and a decrease of anterior chamber depth fur maintaining a emmetropia status, and the steepness and thickness of lens, shallowness of anterior chamber contributed to emmetropia by decreasing the refractive index of lens.

结果 随着年龄增大，眼轴逐渐变短，但同时伴有角膜、晶状体屈光力的增大及前房深度的变浅以维持正视状态，晶状体的增厚、曲率的变大及前房的变浅可能通过屈光指数的减小同样维持了正视状态。

With normal vision were studied. The result showed: 504 eyes (77. 54%) suffered from hyperopia, 66 (10.15%) from myopia, 2(0.31%)from astigmatism and 78(12. 00%) were emmetropia. Among 325 youths, 172 (52.92%) had esophoria (including esophoria-hy- perphoria), 126 (38.7%)exophoria (including exophoria-hyperphoria), 13(4.00%) hyperphoria and 14(4.31%)had orthophoria. No significant...

结果显示，远视者为504眼(77.54％)，近视者66眼(10.15％)，混合散光者2眼(0.31％)，正视者78眼(12.00％)，325人中，内隐斜者为126人(38.77％)，上隐斜者13人(4.00％)，正位者14名人(4.31％)；经用行x列表的x~2检验法分析，屈光不正的类型与斜视的种类之间没有显著联系。

Results 1 there were no significant differences of amplitude of accommodation and accommodative lag between the myopia group and emmetropia group. The differences of amplitude of accommodation between the myopia group and hyperopia group were significant (t=2.21, P=0.03.05; t=2.83, P=0.006.05). 2 The difference of accommodative lag between the dominant eye (0.73±0.31) D and non-dominant eyes (0.81±0.38) D in myopia group was signiflcant.3 The accommodative lag of dominant eyes was (0.68±0.36) D and it of non-dominant eyes was (0.75±0.34) D, the difference was significant (t=2.06, P=0.042.05, n=95).There was no significant difference between the amplitude of accommodation of dominant eye (12.9±3.09) D and non-dominant eyes (12.6±3.09) D.

结果 近视患儿的主导眼和非主导眼的调节幅度和调节滞后与正视儿童均差异无统计学意义；而其主导眼和非主导眼的调节幅度比远视患儿明显更大(t=2.21， P=0.03.05； t=2.83，P=0.006.05)；两组的调节滞后差异无统计学意义。50例近视患儿主导眼和非主导眼的调节滞后值分别为(0.73±0.31)D和(0.81±0.38)D，主导眼和非主导眼间差异有统计学意义(t=2.14，P＝0.038.05)；调节幅度分别为(13.39±3.51)D和(13.26±0.60)D，差异无统计学意义。95例观察对象的主导眼的调节滞后度为(0.68±0.36)D，非主导眼调节滞后度为(0.75±0.34)D，主导眼和非主导眼间的差异有统计学意义(t=2.06， P=0.042.05)；主导眼调节幅度(12.9±3.09)D，非主导眼为(12.6±3.09)D，差异无统计学意义(t=1.49， P=0.14)。

他的鼻子高挺，感觉稍为锋利，鼻翅无肉，无颧，留胡。。，上唇有一道破损后的痕迹，两眼对我不敢正视。。。

Objective To investigate the difference in amplitude of accommodation between emmetropic and myopic subjects with three methods of push-up test, minus-lens test and infrared optometer.

目的 分析正视和近视儿童用不同测量方法测量的眼调节幅度的差异(amplitude of accommodation， AMP)并初步探讨不同方法测量对眼AMP测量的影响。

Methods The refractive state, corneal refractive power, anterior ocular segment length, vitreous length and ocular axial length were measured for 1 336 eyes, including 523 hyperopic eyes, 199 emmetropic eyes and 614 myopic eyes. The relationships of these elements were studied. Results CP had no effect on the refractive state.

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
