Analysis on vision and refraction of primary and middle school students in urban rural areas of Shanghai

  Objective   To investigate the current situation and epidemiological characteristics of vision and refraction amongst primary and secondary school students in urban rural areas of Shanghai, and to provide reference for the prevention and treatment of myopia amongst primary and secondary school students in this area.   Methods   Using cluster sampling method, a total of 4 508 students from grade 1 to grade 8 at nine schools in a community in Shanghai were selected. The vision examination included naked vision, wearing glasses vision and no mydriasis optometry. SPSS 21.0 statistical software was used for data analysis, and statistical significance was considered at P < 0.05.   Results   The rate of poor vision was 60.3% (2 718/4 508), including 43.5% (1 962/4 508) for myopia, 34.6% (1 562/4 508) for astigmatism, 16.1% (724/4 508) for anisometropia and 2.0% (73/4 508) for hyperopia. The prevalence of myopia was 34.1% (1 077/3 162) in primary school students and 65.8% (885/1 346) in junior middle school students. The prevalence of myopia increased with grade (P < 0.01). The prevalence of myopia was lower in boys than in girls (P < 0.05), whereas the prevalence of astigmatism was higher in boys than in girls (P < 0.05). The degree of myopia in the junior middle school group was higher than that in the primary school group (P < 0.05).   Conclusion   The poor vision rate of primary and secondary school students in this area is high, and the main eye disease is myopia. Relevant departments should take corresponding measures to prevent the occurrence and development of myopia according to the epidemiological characteristics of myopia in primary and secondary school students.
