P>Purpose: To evaluate differences between Goldmann Applanation Tonometry (GAT) and Dynamic Controur Tonometry (DCT) in eyes with pseudoexfoliation syndrome (PEX). Methods: Thirty-eight patients (38 eyes) with PEX in both eyes (pseudoexfoliative group, PG) as well as 19 patients (19 eyes) without PEX in either eye (control group, CG), were included. All eyes were phakic. GAT, DCT, the central corneal thickness (CCT) and the axial length of the eyeball (AL) were measured and the difference between GAT and DCT (dIOP) was calculated. Differences in dIOP between CG and PG and correlations of dIOP with CCT and AL were examined. Results: dIOP was significantly (P = 0.02) higher in PG (mean value 3.69 mmHg), compared with CG (mean value 2.15 mmHg). In PG (but not in CG), dIOP was also significantly correlated with AL but not with CCT. Conclusion: The fact that dIOP was significantly higher in PG than in CG implies that PEX may affect ocular biomechanical properties. The significant association of dIOP with AL but not with CCT is in agreement with previous reports and complies with the fact that pseudoexfoliative material is not deposited in corneal stroma.
