Abstract

Objective: To determine the correlation between mean central corneal thickness taken with Galilei dual
Scheimpflug Analyzer and Applanation Ultrasound Pachymetry.
Study Design: Descriptive cross sectional study.
Place and Duration of Study: Armed Forces Institute of Ophthalmology Rawalpindi, from Jul 2013 to Jan 2014.
Material and Methods: Central corneal thickness was measured in 100 eyes of 50 patients. First three readings were taken with Galilei dual Scheimpflug analyzer, with a gap of 1 minute. Then three readings were taken with ultrasound pachymetry after applying topical 0.5% proparacaine (Alcain). The mean of the three readings was used for the analysis.
Results: For right eye the mean central corneal thickness measured by the Galilei dual Scheimpflug analyzer and Ultrasound pachymetry was 544.06μm ± 27.36 and 546.88μm ± 27.71 respectively, and for left eye it was 544.72μm ± 25.47 and 546.52μm ± 26.15 respectively. There was a strong and positive correlation between the two instruments (r=0.969, p=0.000 for right eye and r=0.956, p=0.000 for left eye).
Conclusions: The pachymetry readings with GSA showed strong and positive correlation with those of US pachymetry. So GSA may be considered as an alternative to US Pachymetry, thus avoiding operator-dependent errors, patient discomfort and other disadvantages.
