Objective  To discuss the accuracy and clinical value of Shi′s retinoscopy. Methods  In this cross-sectional study， 100 eyes of 58 patients with ametropia ranging in age from 5 to 38 years were involved in this clinical trial. Shi′s retinoscopy method was used to obtain the predictive value and practical measured value. The astigmatism power and axis were also compared. The subjects were then checked with an autorefracter. Finally， the differences between astigmatism power， axis， the adjustment stability of Shi′s retinoscopy and the measured value obtained from the autorefracter were analyzed using a paired t test. Results  Respective predictive values and practical measured values were compared. The differences were not statistically significant. In addition， the comparison of astigmatism power and axis obtained from Shi′s retinoscopy and the autorefracter did not show a statistically significant difference. However， a comparison of the adjustment stability of the measured values between Shi′s retinoscopy and the autorefracter showed statistically significant differences （t=8.943， 4.066， P<0.01）. Conclusion  Shi′s retinoscopy has the advantages of high accuracy， and quick and simple operation in predicting ametropia. Promotion for wide use in the clinic is merited.
