Abstract

The intraocular pressure and the anteroposterior length of the eye are of great clinical importance for the diagnosis and management, before and after surgery, of congenital glaucoma. It is well-known that the normal intraocular pressure in children is different from the normal levels in adults. We performed the measurements of the intraocular pressure and axial length in 141 children, who had been admitted for eye problem other than glaucoma. The intraocular pressures were measured with the Perkins hand-held applanation tonometer at the beginning of general anesthesia. Simultaneously, A-scan ultrasound measurements of the axial lengths of the eyes were made. In ten children under the age of 2 years, the intraocular pressure was 11.85 +/- 1.35mmHg. In seventy-nine children from 2 to 7 years, the intraocular pressure was 12.80 +/- 1.73mmHg. In fifty-two children from 7 to 15 years, the intraocular pressure was 13.31 +/- 1.79mmHg. The axial lengths of the eyes in children under the age of 2 years, from 2 to 7 years, from 7 to 15 years, were 21.31 +/- 0.97mm, 22.04 +/- 0.92mm, 23.22 +/- 1.00mm respectively. These results would be considered to be the guidelines of the measurement of the intraocular pressure and axial length in children with a suspicion of congenital glaucoma. The difference of the intraocular pressure from other authors would be due to the early measurement of the intraocular pressure at the beginn ing of general anesthesia.
