Abstract:
AIM: To analyze the abnormal refractive status of infants and young children aged 6 to 48 months, and to provide basis for the correction of ametropia and the early prevention and treatment of amblyopia.METHODS: Infants and young children aged 6 to 48 months were examined for refraction by Spot vision screener for natural optometry. Clinical data of infants and young children with refractive abnormalities were collected, Ciliary muscle paralysis agent was used for retinoscopy and optometry, and the results were statistically analyzed.RESULTS: A total of 168 cases(336 eyes)with abnormal Spot refractive outcomes were collected, with a high proportion of hyperopia and astigmatism abnormalities, 38.4% and 28.6%, respectively, while the proportion of myopia was low(12.2%). There were 90 cases of anisometropia(≥1.00 D), among which 41 cases(45.6%)were astigmatic anisometropia, 33 cases(36.7%)were hyperopic anisometropia, and 16 cases(17.8%)were myopic anisometropia, accounting for the least proportion. A total of 109 infants and young children with Spot refractive abnormalities completed ciliary muscle paralysis retinal optometry. The analysis of the difference and correlation between Spot diopter and post ciliary muscle paralysis optometry results showed that the difference in astigmatism was 0.34±0.64 D(P<0.001), the difference in hyperopia was -2.10±1.27 D(P<0.001), and the difference in myopia was -0.43±0.91 D(P=0.023). Although there was a statistical difference between the two results, astigmatism, hyperopia, and myopia were highly positively correlated, respectively(r=0.694, 0.762, 0.909).CONCLUSION: The main refractive abnormalities in infants and young children aged 6 to 48 months are astigmatism, hyperopia, and anisometropia, with fewer abnormalities in myopia. For screening abnormalities, further ciliary muscle paralysis agent retinoscopy and optometry should be performed, and glasses correction should be given to effectively prevent refractive amblyopia in infants and young children.
