| Summary: | AIM:To compare the difference between diopter of refration measured after cycloplegic mydriasis with retinoscopy and hand-held autorefractor so as to explore the feasibility of using hand-held autorefractor for refraction screening in cadet candidates. <p>METHODS:Respectively using hand-held autorefractor and streak retinoscope to do optometry examination in 317 cadet candidates students(634 eyes)after mydriasis. Main index of refraction values(spherical, cylindrical mirror degree and axial)were analyzed by difference test and correlation analysis. And the elimination rate was comparatively analyzed.<p>RESULTS:Diopters of sphere and cyclic refraction measured by hand-held autorefration were significantly higher than those by retinoscopy(<i>P</i><0.05), but the correction analysis showed that there was high correlation(<i>r</i>=0.733, 0.694), axial of refration measured by these two methods were non-significant(<i>P</i>>0.05). The disqualifying rate using autorefraction was much higher than that using retinoscopy. It was easy to be wrongly eliminated.<p>CONCLUSION:Because of the high correlation between diopters of autorefraction measured by retinascopy and autorefractor, autorefraction has application value in refraction screening in cadet candidates with normal vision. |
