Comparison between children dilated computer and retinoscopy

Abstract

AIM: To investigate the dilation effect of computer optometry and retinoscopy optometry before and after mydriasis in children and to understand whether the application of computer refractor in children.METHODS: Therelated data of 500 children cases(1 000 eyes)with ametropia in our hospital were analyzed. The children firstly received computer optometry, and then use the 10g/L atropine sulfate eye gel drops, respectively. After 3d, they were performed computer optometry and retinoscopy, and compared the effect of two refraction.RESULTS: Spherical reading of computer optometry group was 2.70±2.75DS, cylinder degree was 1.54±1.10DC, were lower than those of retinoscopy group(PPPP>0.05). Before mydriasis, astigmatism was 1.54±1.10D, astigmatic axis was(14.38±11.11)°. After mydriasis, astigmatism was 1.45±1.21D and astigmatic axis was(12.78±10.31)°, significantly higher than those of retinoscopy(PCONCLUSION: Children optometry concerns the visual development of children. Computer optometry and retinoscopy are the pros and cons. As for computer optometry can not replace retinoscopy optometry, it can be used as an auxiliary tool for fast optometry.
