Abstract Details

Purpose:

To study the diagnostic capabilities of  UBM in the diagnosis of lens subluxation in patients with cataract and pseudoexfoliation syndrome.

Setting:

Kazakh eye research institute, Kazakhstan, Almaty.

Methods:

78 patients with cataract and pseudoexfoliation syndrome (108 eyes) were examined. The age of patients ranged from 42 to 86 years. All patients underwent slit lamp biomicroscopy and ultrasound biomicroscopy.

Results:

With UBM, the initial changes in the ligamentous apparatus of the lens were manifested by the difference in the length of the fibers of the Zinn ligaments in different segments, their thinning, stretching, in some places thickening, bonding of the fibers. The rupture of the fibers showed a characteristic sign - the appearance of spherophakiya in the defect zone. The lysis of fibers of Zinn ligaments was found in one or several segments of the ligamentous apparatus. Clinical symptoms of lens subluxation during biomicroscopy were diagnosed in 19.4% of cases, and according to UBM data - in 37% of cases.

Conclusions:

– High informativeness of  UBM in the diagnosis of ligamentous apparatus of the lens in patients with cataract and pseudoexfoliation syndrome in the absence of clinical signs of lens subluxation has been revealed.
