title: [Central corneal thickness and its correlations with other ocular biometric data in patients with congenital glaucoma].
abstract: OBJECTIVE
  To study the distribution of the central corneal thickness and its correlations with other biometric data in patients with congenital glaucoma.
  
  
  METHODS
  Patients had been divided into two groups: group "A", composed of patients with congenital glaucoma, being subdivided in two sub-groups: with Haab striae (A1) and without Haab striae (A2), and group"B" that represented the controls.
  
  
  RESULTS
  The group A presented corneal diameter between 11 and 15.5 mm, with mean of 14.13 mm and standard deviation (SD) of 1.28, while group B presented values between 11.5 and 12.5 mm, with average of 12.01 mm SD of 0.09 (t=-8.9723 and p=1.5083 in level 0.05). Glaucomatous patients presented greater mean values of axial diameter (t=-6.46315, p=9.2498 with level of significance of 0.05), and smaller mean keratometry in relation to the controls. The A1 sub-group presented mean central corneal thickness of 539 ± 46 µm, the A2 presented 571 ± 56 µm, and Group B 559 ± 28 µm (t=0.43746 and p=0.66291). The correlation between corneal and axial diameters was positive in both groups. The correlation between corneal diameter and mean keratometric values was negative in both groups.
  
  
  CONCLUSIONS
  Patients with congenital glaucoma presented greater mean of axial dia meter and smaller mean keratometric values compared to the controls. No statistical significant difference of the central corneal thickness was demonstrated. Corneal and axial diameters were correlated positively. Corneal diameter was correlated negatively with the mean keratometry. It was not possible to establish correlations between the central corneal thickness and other biometric data.
