When Does Measured Visual Field Extent Become Adult-like? It Depends

摘要

This paper addresses the question of when the measured visual field extent of infants and very young children reaches adult-like values. Although most studies do not find adult-like average measured visual field extent (AMVF) before children reach 11 months of age, adult-like AMVF has been reported as early as six to seven months of age. In addition to age, the degree to which the AMVF of very young children is adult-like depends on the region of the visual field tested (nasal versus temporal; upper versus lower) and, to some extent, on procedural variations and stimulus parameters used during testing.
