PURPOSE To compare the sensitivity, specificity, and interpretability of a newly developed semiautomated static perimeter based on the preferential looking response to the results of confrontation visual field testing in a group of young and/or developmentally delayed children with and without visual field deficit. %26lt;br%26gt;METHODS The preferential looking perimeter (PLP) uses observation of the child%26apos;s natural eye movement response to an appearing target to determine the peripheral visual field. We compared preferential looking perimetry to confrontation testing in 74 children 3-10 years of age (mean, 6.6 years; median, 7 years), including 32 controls and 42 children with neurological and ocular disorders that could cause significant visual field deficit. %26lt;br%26gt;RESULTS Using confrontation testing as the gold standard, the PLP was 100% sensitive and 100% specific (95% CI, 90%-100%), with excellent interobserver agreement. An interpretable result could be achieved in 15 (71%) of the 21 children in whom confrontation testing was unhelpful. %26lt;br%26gt;CONCLUSIONS PLP is a useful new technique for assessing significant visual field loss in young or developmentally delayed children, with many advantages over confrontation testing.
