Central corneal thickness measurements taken with a handheld pachymeter were repeatable and had “excellent” interobserver reliability, according to a clinical study.

P. Gunvant and colleagues at the Anglia Polytechnic University in Cambridge, England, assessed the intra- and interobserver reliability of Quantel Medical’s portable BVI Pocket Pachymeter in healthy subjects. To test interobserver variability, 42 subjects underwent repeated ultrasonic pachymetry under topical anesthesia. To test intraobserver variability, an additional 30 subjects underwent repeated pachymetry by one observer.

In the interobserver study, mean measurement difference between observers was 0.7 µm. In the intraobserver study, the mean difference between the repeated measurements was 0.9 µm. Measurement variation was less than 0.2%.

The study is published in Eye.
