A research of 1268 infants refraction in Xin Hui City, GuangDong Province

Objective: To study the infant refraction,detect ametopia in mass screening refraction and correct theametropia properly for the treatment and prevention ofamblyopia and strabismus as early as possible. Methods: Therefraction status of 1268 3～6 years old children (2536eyes)were determined with retinoscopy after tropicamide cycloplegia . Results: The results of statistics showed that 1914 eyes (75. 47%) had emmetropia 273 eyes (1O. 76%)hypermetropia. 16 eyes (o.63%) . Sight 0.7～O.9 278 eyes (1O. 96%).≤0.1,15 eyes (O.59%). The degree ofhypermetropia decreased with the increase of age. Thepercentage of astigmatism decreased with the age increase. and the degree of astigmatism also decreased with the age increase.Myopia increased with the age increase. Conclusions: The prevention of amblyopia and strabismus in children should begin at the infant periods and the cases with moderate and severe ametropia should wear eye glasses as early as possible.
