ARVO Presentation Reports Emerging Evidence for Superiority of Dynamic Contour Tonometry to Goldmann Method for Measuring IOP
May 21, 2009
As reported recently on MedScape Today, a presentation at ARVO by Aachal Kotecha, PhD, from the National Institute for Health Research, Biomedical Research Centre for Ophthalmology at Moorfields Eye Hospital NHS Foundation Trust and University College London’s Institute of Ophthalmology in the United Kingdom, indicated that the dynamic contour tonometer (DCT) gives a repeatable and reproducible measure of intraocular pressure (IOP) on central corneal thickness that is superior to the current gold standard in IOP measurement, the Goldmann applanation tonometer (GAT).
While acknowledging that GAT remains the reference standard for measuring IOP, Dr. Kotecha noted that the accuracy of GAT is affected by corneal thickness, resulting in underestimates with a thin cornea and overestimates with a thick cornea. Dr. Kotecha added that her study’s number 1 lesson was the importance of IOP measurement precision.
