Comparison of the results of anterior chamber depth determinated with various instruments

Abstract

Objective To compare the difference, relevances and consistencies of the results of anterior chamber depth determinated with UBM, A scan ultrasonography, Orbscan, IOL Master 700 and IOL Master 5.0. Methods Total of 126 eyes of 63 patients from Jan.2018 to Mar.2018 in outpatient department of Zhengzhou Municipal Second People’s Hospital were sellected. There were 60 eyes of 30 males and 66 eyes of 33 females.The age ranged from 19 to 71 years, with average of (30.13±10.73)years. The anterior chamber depth were determinated with UBM, A scan ultrasonography, Orbscan, IOL Master 700 and IOL Master5.0. Results The average anterior chamber depth with UBM, A scan ultrasonography, Orbscan, IOL Master 700 and IOL Master 5.0 were (3.08±0.29), (3.11±0.35), (2.98±0.28), (3.07±0.28) and(3.46±0.36)mm, respectively.The differences were statistically significant among five groups(F=16.422, P=0.000). The differences were not statistically significant among the four methods except IOL Master 5.0(P=0.160). There were linear correlations among five groups(Pall=0.000)and good consistences. Conclusion There are good consistencies and relevances of the anterior chamber depth with UBM, A scan ultrasonography, Orbscan, IOL Master 700 and IOL Master 5.0. The anterior chamber depth determinated with IOL Master 5.0 are higher than that with other methods.
