Summary: Central corneal thickness is an important biomechanical factor in different ocular diseases. Purpose: Evaluation of the central corneal thickness in the most often occurring refractive errors in children and to assess their possible correlations with refractive error. Material and methods: 168 children (336 eyes) were examined, 88 girls and 80 boys age from 5 to 16 years (mean 10.6). Among them were children with hyperopia, myopia, astigmatism and without refraction errors (control group). For axial length and corneal thickness measurement ophthalmic ultrasound system has been used Ocuscan RxP f. Alcon. Results: In hyperopic group: mean axial length right eye (RE) ? 21.60 mm ? 1.33 mm, left eye (LE) ? 21.67 mm ? 1.02 mm, mean central corneal thickness (CCT) RE ? 579.09 ?m ? 35.11 ?m, LE ? 577.19 ?m ? 32.09 ?m. In myopic group: mean axial length RE ? 23.44 mm ? 1.00 mm, LE ? 23.48 mm ? 11.08 mm; mean CCT RE ? 558.246 ?m ? 29.92 ?m, LE ? 557.90 ?m ? 28.95 ?m. In emmetropic group ? mean axial length RE ? 22.80 mm ? 0.87 mm, LE ? 22.79 mm ? 0.82 mm, mean CCT RE ? 572.30 ?m ? 37.17 ?m, LE ? 569.60 ?m ? 33.49 ?m. Conclusion: Wide individual variations of central corneal thickness are found for examined children. It is independent from refractive errors. Corneal thickness is different in examined refractive errors. Thin corneas are present in myopic eyes, thicker corneas in hyperopic eyes. Correlation of the central corneal thickness with the refractive status, especially with myopia should be considered during eye?s examination in children.
