ABSTRACT
Objective To investigate the visual acuity condition of preschool children in Yangpu District of Shanghai, providing the basis for formulation of corresponding intervention measures for myopia. Methods The inspection equipment was the international standard logarithmic E-word visual acuity chart, and the Canon RK-F1 automatic computer optometry instrument.By using cross-sectional study and random cluster sampling method, a total of 1 415 preschool children in 5 kindergartens in Yangpu District were selected according to their ages and genders, and their visual acuity and refractive parameters were examined with the result being statistically analyzed. Results In preschool children of Yangpu District, their envisage rate was 80.4%, myopia rate 16.7% and hyperopia rate 2.9%.There was no significant difference in the incidence rate of envisage, myopia and hyperopia between different age groups (χ2=3.419, P=0.755) and different genders (χ2=2.433, P=0.296).The rate of poor vision for preschool children in Yangpu was 10.5%.There was a statistically significant difference in the rate of poor vision between different age groups (χ2=9.637, P=0.022) and different genders (χ2=4.191, P=0.041). Conclusion The visual acuity rate and myopia rate in preschool children are not optimistic and need further screening and early intervention.

ABSTRACT
@#AIM: To investigate the compliance and the relative influencing factors of orthokeratology lens in the treatment of teenagers' and children's myopia in Dongguan,and provide a scientific basic for prevention and control of myopia.<p>METHODS: Totally 757 patients of teenagers' and children's myopia with orthokeratology lens in our hospital from January 2017 to December 2017 were collected. Data from medical records and return visits by telephone, short message and Wechat were collated and summarized, then grasp the compliance and the relative influencing factors of orthokeratology lens in the treatment of teenagers' and children's myopia in Dongguan by analyzing re-examine time and persistence in wearing lens.<p>RESULTS: Totally 757 patients with mean age at 11.82±2.234 years old, including 363 males, mean aged 11.66±2.256 years old, and 394 females, mean aged 11.96±2.206 years old, there was no significant difference in age comparison of boys and girls(<i>t</i>=-1.855, <i>P</i>>0.05). In terms of re-examination compliance and persistence on wearing lens, significant difference was observed in educational stage, studying way and parents' education level(<i>P</i><0.05), no significant difference was observed in gender, area, family economic status, vision before and after wearing lens and myopia control effect(<i>P</i>>0.05). Multivariate Logistic regression analysis showed that educational stage, studying way and parents' education level were correlated with re-examination compliance and persistence on wearing lens(<i>P</i><0.05).<p>CONCLUSION: Compliance of orthokeratology lens in the treatment of teenagers' and children's myopia in Dongguan was correlated with educational stage, studying way and parents' education level, to improve the compliance of orthokeratology lens in the treatment of teenagers' and children's myopia, Standardize fitting, standardize care, normative propaganda and education, review on time and regular return visits were important.
