To assess normal intraocular pressure values of the child population the authors examined a group of 215 children aged 4 to 15 years with a normal ophthalmolo- gical finding, a total of 406 eyes. All tonometric examinations were made without general anaesthesia or other pharmacological measures influencing the air-puff contact-free tonometer NT 1100 NIDEK, always the mean of three reliable results. Although there were certain variations of the intraocular pressure, they were not correlated to the child´s age after the age of 4 years. The mean intraocular pressure in the whole group of 406 eyes was 16.08 ± 3.08 mm Hg. Knowledge of normal values of the IOP in children is important for diagnosis as well as for monitoring of already verified glaucoma.
