Abstract

Purpose

To compare anterior segment measurements obtained using the Pentacam; Oculus, HR and the LenStar LS 900 in patients with newly diagnosed glaucoma.

Methods

Patients with ocular hypertension and primary open-angle glaucoma who had been treated with PGA were included in the study. Anterior segment measurements including central corneal thickness (CCT), keratometry, anterior chamber depth (ACD) and white-to-white (WTW) corneal diameter obtained with the optic low-coherent reflectometer (LenStar LS-900, Haag-Streit AG, Switzerland) and with the Scheimpflug system (Pentacam; Oculus, HR) were compared. In order to compare LenStar and Pentacam measurements, paired sample t test and ‘Bland–Altman’ plot were used in the statistical analysis.

Results

Twenty-two female (59.5%) and 15 male (40.5%) totally 37 cases with newly diagnosed glaucoma were included in the study. Anterior segment parameter measurements obtained with both the LenStar and the Pentacam were significantly correlated for right and left eyes, so the right eye values were used in statistical analysis. WTW and ACD values measured with LenStar were statistically significantly higher than those measured with Pentacam (p: 0.0001, p: 0.0001, respectively). There was no statistically significant difference between the CCT values measured by the two devices (p: 0.217).

Conclusion

There was a statistically significant difference between the mean values of ACD and WTW measured with the LenStar and Pentacam. These biometric devices should not be used interchangeably. It should be appropriate to use the same device on follow-up of glaucoma patients.
