Ocular Biometric Characteristics in Preoperative Diagnosis… : Journal of Glaucoma
characteristics of eyes with AAC with zonular laxity to further explore the sensitive parameters for preoperative diagnosis. Methods: This study included 50 patients with AAC with zonular laxity and 54 patients with AAC without zonular laxity. Demographic data, ocular examination results, and biometric parameters on ultrasound biomicroscopy images were compared between the affected and fellow eyes in 2 groups. Parameters significant in the multiple linear regression model were included in a regression equation and the diagnostic efficiency was evaluated by area under the curve. Results: In patients with AAC with zonular laxity, the binocular difference of central ACD, LV in affected eyes, and binocular difference of the LV were significantly larger than those in patients without zonular laxity respectively and these three parameters were all significant in multiple linear regression analysis (all P<0.001). The area under the curve of binocular difference of ACD, LV in affected eyes, an
