Anterior chamber depth measurement in teenagers. Comparison of two techniques

AbstractPurposeThe aim of this study is to determine the anterior chamber depth (ACD) in teenagers using two different devices: partial coherence interferometry IOLMaster (Carl Zeiss Meditec) and anterior segment optical coherence tomography (Visante™ OCT, Carl Zeiss Meditec) and to evaluate the degree of agreement between ACD measurements carried out by both instruments.MethodsIn this prospective study 68 eyes of 34 emmetropic Caucasic patients (18 girls and 16 boys) were analysed. ACD was measured from the anterior corneal surface to anterior surface of the crystalline lens. For each age the ACD size was calculated and the difference between IOLMaster and Visante-OCT measurements was analysed using Bland–Altman plot and paired t-test.ResultsFor all data the mean (SD) anterior chamber depth was 3.56 (0.19)mm with the IOLMaster and 3.65 (0.21)mm with the Visante-OCT. IOLMaster measurements were an average of 0.10 (0.12)mm less than Visante-OCT (paired t-test, p
