OCT provides reproducible pachymetry measurements

November 1, 2003

Mainz, Germany-Corneal thickness can be reproducibly measured using either noncontact optical coherence tomography (OCT) or ultrasound pachymetry. A comparison of results obtained with those two techniques, however, indicates that ultrasound pachymetry may underestimate corneal thickness, probably due to its applana- tion of the cornea, said Peter Breil, MD.
