to evaluate the difference in IOP measurements between Goldmann aplanation tonometry (GAT) and dynamic contour tonometry (DCT) in eyes submitted to penetrating keratoplasty and normal control eyes.
IOP measurements by GAT and DCT and central corneal thickness measurements (CCT) by ultrasonic pachymetry were obtained from 11 eyes of 8 consecutive patients submitted to penetrating keratoplasty and from 13 eyes of 8 normal healthy subjects.
Mean IOP measurements were significantly higher with DCT compared to GAT in eyes submitted to penetrating keratoplasty (18.4 mmHg versus 14.9 mmHg, respectively, p = 0.04). Similar results were observed in normal control eyes (17.3 mmHg vs 14.4 mmHg, respectively, p = 0.02). A significant linear correlation between GAT measurements and CCT was observed in normal eyes but not in eyes submitted to penetrating keratoplasty. No significant linear correlation was observed between IOP measurements by DCT and CCT in both groups.
Dynamic contour tonometry provides higher IOP measurements than Goldmann aplanation tonometry in eyes submitted to penetrating keratoplasty and also in normal control eyes.
