Visual Field Testing
Assessment of the visual field in children is useful, but the testing process can be challenging. Automated testing can begin at age 5 years; the results become more reliable as the child approaches 7–8 years of age. As for adults, abnormalities should be confirmed with repeat testing. Although there is no normative database for children, the age correction for mean deviation is small (0.7 dB/decade). Other indices, the pattern standard deviation, the glaucoma hemifield test, and glaucoma change probability are largely unaffected by age.
