| Abstract: | Objective: To investigate and compare the cycloplegic effect of cyclopentolate, compound topicamide and atropine in children with different ages, refractive status and accommodative esotropia. Methods: This prospective clinical study had been conducted at Renmin Hospital of Wuhan University between September 2018 and September 2019 in 283 children (566 eyes) of 3-12 years old with refractive error. All the children were given 1% atropine to obtain the refractive diopter, and they were randomly divided into group A and group B. The two group are divided into 3-<6 years old group and 6-<12 years old group according to age. The 3-<6 years old group and the 6-<12 years old group are divided into three subgroups: The myopia group without esotropia, the hyperopia group without esotropia and the esotropia group. After 5 weeks, pupil size and light reflex back to normal. Group A received 1% cyclopentolate hydrochloride eye drops for computer optometry, and group B received 0.5% compound tropicamide eye drops for computer optometry. The Wilcoxon signed rank sum test was used to statistically analyze the difference of spherical equivalent of computer optometry before and after 1% atropine, and the difference of computer optometry after different cycloplegia. Results: The SE after 1% atropine was greater than before 1% atropine, the difference of SE was 1.75(1.00-2.75)D, and the difference was statistically significant (Z=-20.62, P<0.001). The difference was more obvious children with aged 3 to 6, children with hyperopia and children with esotropia (P<0.001). In group A, the SE after using 1% atropine was greater than that after using 1% cyclopentolate, and the difference of SE was 0.25(0.13-0.50)D (Z=-11.49, P<0.001). The difference of SE in 3-<6 years old group after using 1% atropine and 1% cyclopentolate in the myopia group without esotropia, hyperopia group without esotropia and esotropia group were 0.25(0.25-0.25)D, 0.38(0.25-0.50)D, 0.50(0.38-0.75)D (Z=-3.34, -7.36, -4.95, all P<0.001). The difference of SE of that 3 subgroups in the 6-<12 years group were 0(0-0.12)D, 0.25(0.12-0.25)D, 0.44(0.28-0.69)D (Z=-0.83, P=0.405; Z=-5.30, P<0.001; Z=-3.53, P<0.001). In group B, the SE after using 1% atropine was greater than that after using 0.5% compound tropicamide, and the difference of SE was 0.25(0.13-0.50)D (Z=-15.46, P<0.001). The difference of SE in 3-<6 years old group after using 1% atropine and 0.5% compound tropicamide in the myopia group without esotropia, hyperopia group without esotropia and esotropia group were 0.25(0.19- 0.25)D, 0.38(0.25-0.75)D, 0.69(0.30-1.03)D (Z=-3.15, P=0.002; Z=-9.89, P<0.001; Z=-4.79, P<0.001). The difference of SE of that 3 subgroups in the 6-<12 years group were 0(0-0.12)D, 0.32(0.13-0.38)D, 0.50(0.41-0.50)D (Z=-1.37, P=0.171; Z=-7.15, P<0.001; Z=-4.37, P<0.001). Conclusions: The spherical equivalent of mydriasis refraction with 1% cyclopentolate eye drops or 0.5% compound tropicamide eye drops is similar to that with 1% atropine in myopic children aged 6 to 12 years without esotropia, and it is different from that with 1% atropine in 3-<6 years old children and children with hyperopia and esotropia at 6-<12 years old. |
