方法：采用自身对照研究。入选10～15岁近视儿童48例，睫状肌麻痹下使用Grand Seiko WAM5500 型红外验光仪测量右眼视网膜中心凹0°以及鼻颞侧10°，20°，30°的屈光值，分别在裸眼和配戴单光眼镜时测量。

结果：近视儿童的平均屈光度为-3.99±1.22D，相对周边屈光度在水平视野上为远视性离焦。随着注视角度的增大，相对远视性离焦量增大。戴镜后的相对周边远视性离焦量较裸眼时增大(P<0.01)。戴镜前后的J₁₈₀及J₄₅相比较无统计学差异。

结论：近视儿童配戴单光镜后周边视网膜远视性离焦量增大。根据周边视网膜的聚焦状态改进镜片的设计可能会成为近视矫正的新思路。

METHODS: It was a self-control study. Totally 48 children aged 10 to 15 years old were involved. Cycloplegic autorefraction from right eyes was measured using Grand Seiko WAM5500 infrared refractometer and the value was at 0° at the retinal central fovea, at 10°, 20°, and 30° in the temporal and nasal visual fields. Measurements were taken on each subject both while uncorrected and while wearing SVLs.

RESULTS: The mean spherical equivalent refraction of myopia children was -3.99±1.22D. Relative peripheral hyperopia defocus was found in horizontal visual field and increased with the increase of eccentricity. Relative peripheral hyperopic defocus increased when wearing spectacle correction, comparing with the uncorrected state(P<0.05). There was no statistical significance for J₁₈₀ and J₄₅ when compared wearing spectacle and uncorrected state.

CONCLUSION: Relative peripheral hyperopic defocus increased when wearing spectacle correction, comparing with the uncorrected state in myopia children. To improve the design of the lens based on the focus state of the peripheral retina may become the new ideas of myopia correction.
