目的研究麻痹睫状肌对豚鼠眼屈光度检测的影响。设计实验研究。研究对象10周龄英国种豚鼠12只(24眼)。方法带状光检影法(SR)在应用1%环戊通(cyclopentolate cycloplegic)散瞳前、后各检测双眼屈光度3次,间隔时间1小时。主要指标豚鼠眼球镜、柱镜和等效球镜度数。结果豚鼠眼散瞳前后平均等效球镜值分别为(1.92±0.79)D和(2.08±0.79)D,配对t检验散瞳前后球镜、柱镜和等效球镜测量值的差异无统计学意义。方差分析散瞳和不同测量时间两个分析因素对球镜、柱镜和等效球镜的测量结果的影响均无统计学意义。结论1%环戊通对成年豚鼠眼屈光度检测结果影响有限,成年豚鼠可以在自然生理状态下进行屈光度检测。
Objective To study the effect of ciliary muscle paralysis on the refraction of guinea pigs. Design experiment research. Participants Twelve (12) British guinea pigs (24 eyes) were enrolled. Methods The strip photomicrography (SR) was used to detect the refractive power of both eyes before and after 1% cyclopentolate cycloplegic dilation for 3 hours with an interval of 1 hour. Guinea pig eyeballs main indicators, cylinder and equivalent spherical degrees. Results The average equivalent spherical diameters before and after mydriasis in guinea pigs were (1.92 ± 0.79) D and (2.08 ± 0.79) D, respectively. There was no statistical difference between spherical and cylinder measurements before and after mydriasis Significance of learning. Variance analysis Multivitamin and different measurement time of the two analytical factors on the spherical mirror, cylinder and the equivalent spherical mirror measurement results were not statistically significant. Conclusions 1% cyclopentolate has a limited effect on the diopter detection of adult guinea pigs. Adult guinea pigs can observe the diopter under natural physiological conditions.
