Abstract

Purpose : To compare the Anterior Chamber Depth (ACD) measures obtained with two different techniques: the Scheimpflug camera (Pentacam HR Oculus®) and by interferometry (IOL Master 500 Carl Zeiss®).

Methods : Outpatients examination data from the Ophthalmology Service of the Hospital de Olhos Paulista, São Paulo-Brazil, performed in the period of May 2014 to March 2016 were retrospectively evaluated. Only patients with no previous ocular surgery or other ophthalmological comorbidities than cataract were included in this series. ACD sets of measurements were obtained consecutivally by an experienced examiner in both devices (IOL Master 500® and Pentacam HR®) and a single measure of good quality index was recorded for each equipment. The values were compared and had their agreement accessed by Intraclass Correlation Coeficient (ICC) and Bland-Altmann method in SPSS IBM® program version 16.0. Values of p < 0.05 were considered to be statistically significant differences. This study was approved by the Research and Etthics Comitee of the Santa Casa Hospital of São Paulo, Brazil.

Results : ACD measurements of 468 eyes from 270 patients were evaluated. The mean age of the population was 68 ± 1,17 years, ranging from 32 to 93. The mean ACD value obtained by Pentacam HR® was 3.14 ± 0.38 mm (range 2.03 - 4.50) and by IOL Master® 500 was 3.12 ± 0.38 mm (range 1.99 – 5.29). The ICC observed in this series was 0.91 (p<0.001, CI 99%: 0.89- 0.93; type “a” model with absolute agreement for single measures). A high degree of reliability was found between the measures of ACD in this series.

Conclusions : The values of ACD obtained with both devices have demonstrated a strong correlation.
