title: Photic driving in the early premature infant.
abstract: Thirty-two infants born at gestational ages of 27-32 weeks were subjected to isolated flashes and intermittent photic stimulation. Their gestational age (GA) was assessed by maternal dates, physical examination and, when possible, examination of lens vasculature. The babies were selected for being of less than 33 weeks GA and being normal for GA on examination. Responses to isolated flashes were present in 63% and photic driving at 2-10 f/sec was present in 66% of the babies. Apparent discrepancies of these findings with previous reports about photic driving in prematures are discussed.
