[Central corneal thickness and intraocular pressure in the youth].
OBJECTIVE
To estimate the central corneal thickness in young patients and to evaluate the relationship between the intraocular pressure (IOP) and pachometry.


METHODS
Eighty eyes of 40 children at the age from 9-18 years, mean 13.75 were examined. The applanation tonometry, pachometry, refraction and examination of corneal diameter were done. To statistical purpose t-Student test was used alpha = 0.05.


RESULTS
IOP ranged from 12 to 24 mmHg, in 32 eyes was above 17 mmHg, mean 20.2 +/- 1.46 mmHg (I group) and in 48 eyeballs ranged from 12 to 17 mmHg, mean 15.6 +/- 0.96 mmHg (II group), p = 0. In the I group pachometry was from 480 to 591 microm, mean 542 +/- 11.1 and in the II group from 451 to 570 microm mean 521.7 +/- 9.39 p = 0.006. Mean refractive error in the I group was -0.4 D (from -5.0 to +4.0 D) and in the II group mean -0.8 (from -6.25 to +4.75), p = 0.45. In the both groups corneal diameter was from 11.5 to 12.5 mm. Comparing eyeballs of patients at similar age, refraction and corneal diameter, it was shown that central corneal thickness in the group with higher IOP was statistically significantly bigger than in the group II.


CONCLUSIONS
Measuring IOP in children we have to take into account the corneal thickness.
