Abstract

Objective: To evaluate the accuracy of 35 MHz ultrasound microbioscopy in diagnosis of damages of posterior lens capsule in cases of traumatic cataracts after ocular penetration.  Subjects and research methods: Descriptive study without a control group on 49 cases with ocular penetration, which had been sutured and were treated by cataract surgeries with or without intraocular lens implantation at the Eye Trauma Department of Vietnam National Eye Hospital from 4/2018 to 5/2019. Results: The male/female ratio in the study was approximately 2,7/1. The mean age was 43,4±19,7 years old (the range was 14-63 years old). On UBM images, there were 28 cases diagnosed with posterior lens capsule tear, but during the operation, only 25 cases were having the damages. The sensitivity, specificity, positive predictive value and negative predictive value were 100%, 87,5%, 89,3% and 100%, respectively. Conclusion: Although there are some disadvantages of 35 MHz ultrasound microbioscopy, it is an effective method to evaluate the posterior lens capsule in traumatic cataracts after ocular penetration.
