Comparison of Goldmann applanation tonometry and Pascal Contour Tonomtery in relatopn to central corneal thickness and corneal curvature

Summary:

Purpose : To assess the influence of central corneal thickness and corneal curvature in tonometry measurements taken by Goldmann applanation tonometry (GAT) and Pascal Dynamic Contour Tonometry (DCT).
Methods: Prospective study of 185 eyes from 97 subjects, attending outpatient ophthalmology appointments, who underwent intraocular pressure measurements by Goldmann applanation tonometer (GAT) and Pascal Dynamic contour tonometer (DCT). Central corneal thickness (cct) and corneal curvature were obtained using ultrasound pachymetry and orbscan topography respectively. All measurements carried out among males and females during the period 2009 to 2012. Apart from the usual descriptive and exploratory data analysis, linear correlation coefficients were estimated, multiple scatter plots were produced and one-way analysis of variance was performed.
Results: Mean IOP measurements obtained were 17,21 ± 4,10mmHg by DCT and 13,23 ± 4,07 mmHg by GAT. Mean difference between the GAT and DCT measurements was 3,88 ±2,8 mmHg. Mean CCT and Corneal curvature were 522,78 ± 52 μm and 43,83 ± 2,9823 Diopters respectively.
Conclusions: Intraocular pressure measured by GAT was consistently lower when compared with DCT, and this difference was greatest with thinner CCT. Flat corneas seem to influence GAT readings compared to DCT.
