[Clinical significance of preoperative B-ultrasonography for traumatic cataract]
1Department of Ophthalomology, Bao Gang Hospital, Shanghai Second Medical University, Shanghai 201900.
Objective:
To approach the clinical significance of B-ultrasonography in detection of the break of posterior lens capsule in traumatic cataract.
Methods:
30 patients (30 eyes) of traumatic cataract underwent preoperative B-ultrasonography and intraoperative microscopic examination to evaluate the status of posterior lens capsule.
Results:
14 eyes showed posterior lens capsule unbroken in B-ultrasonography. Of them, 12 eyes were confirmed by surgery. 16 eyes showed rupture of the posterior lens capsule in B-ultrasonography. Among them 14 eyes were confirmed by surgery and in 2 eyes there was no break at the posterior lens capsule.
Conclusions:
B-ultrasonography for preoperative traumatic cataract is harmless, painless, simple in operative procedure and accurate, thus it can be used as a routine examination to show the status of posterior lens capsule in traumatic cataract.
