Correlation analysis between the test results of PVEP in children with ametropic amblyopia

Abstract

AIM: To analyze the impact of age on children with amblyopia and the correlation between pattern visual evoked potential(PVEP)test results and age.METHODS: A total of 136 cases(272 eyes)of children with ametropic amblyopia in our hospital from June 2012 to June 2014 were analyzed. Based on the best corrected visual acuity(BCVA): BCVA ≥0.5, 0.3≤BCVAt test was used to analyze the differences between each age subgroups. Then, age was subdivided into 4 sections(4～RESULTS: With an increase in the degree of amblyopia, the LP100 increased and the AP100 decreased. The differences between 3 groups in the LP100 and AP100 were statistically significant(F=135.22, 16.74; P=0.007t=8.36, 5.37, 2.48; P=0.00, 0.00, 0.02), and the AP100 of the former were less than those of the latter(t=6.76, 4.88, 2.85; P=0.00, 0.00, 0.01). Age was an independent risk factor for amblyopia diagnosis(P CI=0.714～0.785).CONCLUSION: Age is independently associated with the diagnosis of ametropic amblyopia, to different ages of children, the same vision represent different functional significance. In measuring the severity of amblyopia in children, different ages respond to adopt different standards.
