Comparison of central corneal thickness measured with anterior segment optical coherence tomography versus ultrasonic pachymetry.
PURPOSE To compare central corneal thickness measured with anterior segment optical coherence tomography (AS-OCT) and ultrasonic pachymetry (UP). METHOD A prospective, observational and cross-sectional study was performed. The central corneal thickness was measured in 112 eyes of 112 consecutive patients with AS-OCT and UP. All examinations were performed by the same examiner. The measurement...
متن کاملComparison of optical coherence reflectometry and ultrasound central corneal pachymetry.
In 50 eyes of 25 patients we prospectively measured the central corneal thickness (CCT) comparing the OLCR (Optical Low Coherence Reflectometry) pachymeter with the contact ultrasound pachymeter. The OLCR system was mounted on to a Haag-Streit slit lamp. Every single measurement was the result of 5 scans. With the contact ultrasound Sonomed pachymeter we performed 5 separate measurements and ca...
متن کاملComparison of optical and ultrasound central corneal pachymetry.
In 100 eyes of 50 patients central corneal thickness was measured comparing optical to ultrasound pachymetry. With optical pachymetry the values were 1 to 40 micrometer (microns) lower in 64 eyes compared to ultrasound pachymetry. With ultrasound pachymetry the values were 1 to 18 microns lower in 26 eyes compared to optical pachymetry. In 10 cases no difference in pachymetry readings was seen ...
متن کاملCorneal Thickness in Pigs Measured by Ultrasound Pachymetry In Vivo
Corneal transplantation is the most frequently performed type of tissue grafting (George & Larkin, 2004). It is a highly successful treatment of severe corneal disease. However, transplantation of tissue and organs in humans has a major setback: availability of donors. To solve this, there are currently many studies on the possible use of the pig as a source of hearts, kidneys, livers, Islets o...
متن کاملComparison of central corneal thickness: ultrasound pachymetry versus slit-lamp optical coherence tomography, specular microscopy, and Orbscan
BACKGROUND Central corneal thickness (CCT) can be measured by using contact and non-contact methods. Ultrasound 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. Not many stud...
