title: Dynamic contour tonometry for intraocular pressure measurement.
abstract: OBJECTIVE
  To compare dynamic contour tonometry as a new method for intraocular pressure measurement with Goldmann applanation tonometry.
  
  
  METHODS
  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 measurements were additionally performed.
  
  
  RESULTS
  Mean dynamic contour tonometric measurements (18.71 +/- 5.90 mm Hg) were significantly (P < .001) higher than mean applanation 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. Correlation with central corneal thickness was significant for applanation tonometry (P = .036), while dynamic contour tonometry was statistically independent of corneal thickness (P = .32).
  
  
  CONCLUSIONS
  For measurement of intraocular pressure, dynamic contour tonometry may offer a new technology, which, compared with applanation tonometry, may show a lower dependence on central corneal thickness.
