Comparison of dynamic contour tonometry and Goldmann applanation tonometry in relation to central corneal thickness in primary congenital glaucoma

Graefe's Archive for Clinical and Experimental Ophthalmology, 05/11/2012

The differences between dynamic contour tonometer (DCT) and Goldmann applanation tonometer (GAT) readings were not influenced by central corneal thickness in this series of patients. Considering the weak correlation and the poor agreement observed between GAT and DCT measurements and that they both may be affected by corneal biomechanical changes, these methods should not be used interchangeably, and may possibly give no meaningful intraocular pressure values in PCG patients.
