Abstract

Purpose:: To compare the central anterior chamber depth (ACD) measurements using Scanning Peripheral Anterior Chamber Depth Analyser (SPAC) and IOL Master.

Methods:: SPAC is a new non-contact instrument using optical principles to grade the peripheral and central anterior chamber depth. A community based screening study in Singapore recruited 497 subjects over the age of 50 years without any ophthalmic complaints. All subjects underwent examination by Scanning Peripheral Anterior Chamber Depth Analyser (SPAC, Takagi, Japan) and IOL Master (Carl Zeiss Meditec, Jena,Germany) in the dark by the same operator. Central anterior chamber depth (ACD) measurements using SPAC and IOL Master were compared using the Bland Altman analysis.

Results:: A total of 232 men (46.7%) and 265 women (53.3%) were examined, with a mean age of 63.4 years ± 7.9 (SD). The mean anterior chamber depth was 3.08 mm ± 0.36 (SD) with the IOL Master and 3.10 mm ± 0.44 (SD) with SPAC. There was good correlation between the two devices, with the 95 % limits of agreement (IOL Master-SPAC) being -0.57 mm to 0.50 mm . SPAC measurements were significantly deeper than IOL Master with the mean difference between SPAC and IOL Master being 0.027 ± 0.012 mm (SE) , 95% CI 0.003-0.051 ; (p =0.0267 )

Conclusions:: SPAC and IOL Master are non-contact optical devices, showing good agreement in anterior chamber depth measurements. IOL Master gave consistently shallower values than SPAC.
