To compare the anterior chamber depth (ACD) using ultrasonic and optical measurements. In this prospective study, ultrasound and optical (Orbscan) devices were employed to measure ACD in 42 eyes of 21 myopic volunteers. ACD values were compared using the paired-sample Student t test. The correlation of ACD values obtained from two groups was assessed by linear regression analysis. The difference of mean ACD values between the ultrasound (3.02 +/- 0.37 mm) and Orbscan (3.56 +/- 0.42 mm) method was statistically significant difference (p < 0.0001). The optical measurement of ACD in healthy myopic Thai eyes is, on average, 0.54 mm greater than ultrasonic measurement; however, both methods posses a significant linear correlation.
