Normal Intraocular Pressure in Children from Birth to Five Years of Age

Abstract

The examination is generally carried out with the child supported at the slit lamp by the anesthesiologist (see Chap. 4). Goldmann’s applanation tonometer is generally used (Fig. 5.1a). Today we also use Pascal’s tonometer, which gives us the pressure corrected for corneal thickness (Fig. 5.1b). After operating, only the ocular pressure and the axial length need to be checked. This can be done on a stretcher while the child is under anesthesia in a supine position. In this case, Draeger’s hand applanation tonometer is very useful (Fig. 5.1c). We sometimes also use the Goldmann hand applanation tonometer (Fig. 5.1d), which is very precise, but there are very few units manufactured by Haag-Streit. The Perkins tonometer can also be used.
