There are many recordings of intraocular pressures of both normal and abnormal eyes, but a careful review of the literature reveals that the only previous recordings of tonometer tensions in the newborn were made by Brockhurst1 on 59 premature infants. This paper will analyze the results of a study involving 32 full-term infants in whom the intraocular pressure was measured with a Schiøtz impression tonometer within one hour after birth.

Method of Study  A total of 110 newborns were seen no more than one hour after birth, and an attempt was made to obtain a tonometer tension. In only 32 cases out of this entire group was it possible to determine a tension which was considered to be truly reflective of the newborn's intraocular pressure.Immediately after delivery the child was brought into the newborn nursery, cleaned, and wrapped in a blanket which restrained his hands.
