WebSep 25, 2009 · Pachymetry is an important part of the evaluation and management of ocular hypertension and glaucoma. Several techniques are available to reliably and reproducibly measure corneal thickness. The methodologies used in these techniques are based on either ultrasonic or optical principles. WebUltrasound pachymetry (US pachymetry) is a contact method for measuring CCT and is perhaps the most commonly used method. However, non-contact methods like scanning slit topography (Orbscan II), slit-lamp optical coherence tomography (SL-OCT), and specular microscopy are also used.
