According to a prospective review study by H. Gimbel, A. Willerscheidt (1993), among 2967 cataract cases analyzed in 1991, mature intumescent cataract was observed in 34 (1.15%) patients.
To determine the parameters of the ocular anterior segment in patients with intumescent cataract and in their fellow eyes using ultrasound biomicroscopy (UBM) for identification of differential characteristics of intumescent cataract.
The results of preoperative diagnostic examination of the anterior segment of the eye with UBM of 21 patients (21 eyes) with intumescent cataract and their 21 fellow eyes (42 eyes in total) were analyzed.
The mean anterior chamber depth according to UBM was 1.96±0.108 mm (from corneal endothelium), in the fellow eyes - 2.74±0.11 mm. The anterior chamber angle was 11.54±2.19°, in the fellow eyes - 20.63±4.08°. The lens thickness in the eyes with intumescent cataract was 5.26±0.13 mm, in the fellow eyes - 4.34±0.09 mm. The length of Zinn ligaments in the external, interior and superior ocular segments of the main group eyes were equal, in the inferior segments they were longer by 0.1 mm. The difference in Zinn ligament length in the eyes with intumescent cataract and fellow eyes was approximately 0.1-0.15 mm in all segments. The equatorial angle in the eyes with intumescent cataract was 32.52±0.92°, in the fellow eyes - 14.85±1.09°.
A differential symptom of intumescent cataract was identified - complete spherophakia, as confirmed by a specific UBM sign: increase of the equatorial angle by 17° in comparison with the fellow eye, while the length of Zinn ligament remains equal in all segments.
根据H. 金贝尔、A. 维勒斯谢特（1993年）的一项前瞻性回顾性研究，在1991年分析的2967例白内障病例中，有34例（1.15%）患者为成熟肿胀性白内障。
使用超声生物显微镜（UBM）确定肿胀性白内障患者及其对侧眼的眼前节参数，以识别肿胀性白内障的差异特征。
分析了21例（21只眼）肿胀性白内障患者及其21只对侧眼（共42只眼）术前通过UBM对眼前节进行诊断检查的结果。
根据UBM测量，患眼的平均前房深度为1.96±0.108毫米（从角膜内皮起），对侧眼为2.74±0.11毫米。患眼的前房角为11.54±2.19°，对侧眼为20.63±4.08°。肿胀性白内障患眼的晶状体厚度为5.26±0.13毫米，对侧眼为4.34±0.09毫米。主要组患眼的外部、内部和上部眼段的睫状小带长度相等，下部眼段长0.1毫米。肿胀性白内障患眼与对侧眼睫状小带长度在所有眼段的差异约为0.1 - 0.15毫米。肿胀性白内障患眼赤道角为32.52±0.92°，对侧眼为14.85±1.09°。
确定了肿胀性白内障的一个差异症状——完全球形晶状体，这由一个特定的UBM征象证实：与对侧眼相比赤道角增加17°，而睫状小带在所有眼段长度保持相等。
