Objective To study the retinal light sensitivity of central visual field in normal children. Methods The QZS-Ⅱ automated perimetry was used to assess the visual field of centro-30 deg;and centro-6 deg; in normal or ametropic eyes in 60 eyes of 5~9 years old children. Results The mean sensitivity(MS)was not influenced by sex,age and laterality and ametropia of the eye.The normal type of dB distribution was obviously higher than the abnormal(P<0.01).We set normal range as 30 deg;MS>19.3 dB, 6 deg;MS>22.5 dB.The abnormality of value or distribution didn prime;t appear in the same field. Conclusions In normal children,the dB distribution of visual field was mainly of the normal type.We suggest that in evaluating function of visual filed of the children,the dB distribution of centro-30 deg;and centro-6 deg;field and the value of MS should be included.
