To compare central corneal thickness measurements using the ultrasound pachymeter, Orbscan, and the Artemis-2 (Very high- frequency digital ultrasound).
The central corneal thickness of 8 eyes (4 subjects) were scanned using first the Orbscan, followed by the ultrasound pachymeter, and finally by the Artemis-2. Each subject's cornea was measured at the same time of day using the three modalities listed above. It is estimated that final enrollment in this study will be approximately 40 eyes.
Measurements taken with the Artemis-2 and the ultrasound pachymeter correlated well (r=0.99, p<0.0001). In addition, the Artmeis-2 and Orbscan measurements correlated well (r=0.942, p=0.0005). Analysis of variance showed no significant difference existed between measurement of central corneal thickness using the three different measurement modalities (F=0.0031, p=0.997).
Measurement of central corneal thickness using an ultrasound pachymeter, Orbscan and the Artemis 2, a novel ultrasound device for imaging the cornea and anterior segment, correlate well with one another.
