Intraocular pressure in school myopia

Abstract The relationship between intraocular pressure and ocular refraction and axial length were studied in a follow‐up of myopic children and in a cross‐section sample of school children. In the follow‐up group intraocular pressure significantly decreased with age. Mean intraocular pressure at the mean age of 10.9 years was 17.4 mmHg, and three years later 16.1 mmHg. Intraocular pressure above 20 mmHg was recorded in 7.6% of total measurements in the follow‐up group and in 8.7% of cases in the cross‐section sample. There was a significant correlation between mean intraocular pressure and the spherical equivalent both at the beginning and at the end of the study in the follow‐up group and in the cross‐section sample among the boys only. There was also a significant positive correlation between intraocular pressure and axial length at the end of the follow‐up among the boys but not among the girls.
