RESUMO
Objective To compare the changes of retinal sensitivity of central 30? visual field after correction with spectacles with those before correction in juveniles and to provide data for the necessity of correction with spectacles in the measurement of juvenile central visual field. Methods The changes of the retinal sensitivity of central 30? visual field after correction with spectacles in 122 eyes of juveniles were measured using Humphrev 750 Ⅱ perimeter, and were compared with those before correction. Results All the myopic eyes of 122 juveniles passed the reliability of parameters. Among the detected eyes, 110 eyes showed degree dependent changes of the retinal sensitivity of central visual field. Conclusion Correction with spectacles should be used for the measurement of central visual field in juveniles. Otherwise, the results might be unreliable, especially in the cases with moderate and high myopia.
