PURPOSE: To compare dynamic contour tonometry as a new method for intraocular pressure measurement with Goldmann applanation tonometry. DESIGN: Clinical observational study. METHODS: The study included 176 eyes of 126 subjects (39 eyes with open-angle glaucoma,137 normal eyes) and consisted of 528 dynamic contour measurements and 352 Goldmann tonometry measurements. Corneal pachymetry measureme nts were additionally performed. RESULTS: Mean dynamic contour tonometric measur ements (18.71 ±5.90 mm Hg) were significantly (P< .001) higher than mean applan ation tonometric values (16.98±5.86 mm Hg), correlating significantly with each other (r 2=.905, P< .001). The slope of the regression line was 0.95. Correlati on with central corneal thickness was significant for applanation tonometry (P=. 036), while dynamic contour tonometry was statistically independent of corneal t hickness (P=.32). CONCLUSIONS: For measurement of intraocular pressure, dynamic contour tonometry may offer a new technology, which, compared with applanation t onometry, may show a lower dependence on central corneal thickness.
