| description | AIM: To compare the results of IOL Master, contact and immersion A-scan ultrasound measurements for anterior chamber depth(ACD), and evaluate the difference and consistency.<p>METHODS:Fifty-eight cases(98 eyes)with age-related cataract during July to October in 2013 did the A-scan ultrasound with contact and immersion measurements and IOL Master to get the results of ACD. Difference in measurements between methods was assessed using the variance analysisi. Consistency was assessed using Bland-Altman.<p>RESULTS: The ACD measured by IOL Master was 2.31～3.90mm, the mean was 3.03±0.38mm. The ACD measured by contact A-scan ultrasound was 1.51～4.06mm, the mean was 2.88±0.56mm. The ACD measured by immersion A-scan ultrasound was 1.99～4.17mm, the mean was 3.17±0.38mm. The results of IOL Master and contact A-scan ultrasound had statistical differences(<i>P</i>=0.022<0.05). The results of IOL Master and immersion A-scan ultrasound had statistical differences(<i>P</i>=0.031<0.05). The results of contact A-scan ultrasound and immersion A-scan ultrasound had statistical differences(<i>P</i>=0.000<0.05). The consistency between three methods was poor.<p>CONCLUSION: The rank of ACD of patients with cataract is immersion A-scan ultrasound, IOL Master and contact A-scan ultrasound. The consistency is poor, and the three methods can't be interchanged clinically. |
