AIM
To evaluate the application of ultrasound biomicroscopy (UBM) in the examination of lacrimal canalicular diseases, and to investigate UBM image characteristics of lacrimal canaliculi in disease states.
METHODS
Sixty cases (63 eyes, 69 canaliculi) of lacrimal canalicular diseases were enrolled that included 32 patients (32 eyes, 32 canaliculi) with chronic lacrimal canaliculitis, 18 patients (18 eyes, 18 canaliculi) with previous lacrimal canalicular laceration, 9 patients (12 eyes, 18 canaliculi) with congenital absence of lacrimal puncta and canaliculi, and 1 case (1 eye, 1 canaliculus) of canalicular mass. The patients were examined using UBM, and disease-specific features of the UBM images were noted.
RESULTS
UBM imaging of lacrimal canaliculi in chronic canaliculitis patients showed obvious ectasia of the lacrimal canalicular lumen. Dot-like moderate echoic signals were detected on some ectatic lumina of the lacrimal canaliculus. Some lumen-like structures of the lower lacrimal canaliculus were observed in 2 (2 eyes, 2 canaliculi) of the 9 patients (12 eyes, 18 canaliculi) with congenital absence of the lacrimal canaliculus. Of the 18 patients (18 eyes, 18 canaliculi) with previous lacrimal canalicular laceration, the lacerated end on the nasal side of the lacrimal canaliculus was detected only in 14 patients (14 eyes, 14 canaliculi).
CONCLUSION
UBM can be used to evaluate lacrimal canalicular diseases and can provide an imaging basis for the diagnosis of lacrimal canalicular diseases.
目的
评估超声生物显微镜（UBM）在泪小管疾病检查中的应用，并研究疾病状态下泪小管的UBM图像特征。
方法
纳入60例（63眼，69条泪小管）泪小管疾病患者，其中慢性泪小管炎患者32例（32眼，32条泪小管），既往泪小管裂伤患者18例（18眼，18条泪小管），先天性泪点和泪小管缺如患者9例（12眼，18条泪小管），泪小管肿物患者1例（1眼，1条泪小管）。对患者进行UBM检查，并记录UBM图像的疾病特异性特征。
结果
慢性泪小管炎患者泪小管的UBM成像显示泪小管管腔明显扩张。在部分扩张的泪小管管腔内检测到点状中等回声信号。9例（12眼，18条泪小管）先天性泪小管缺如患者中有2例（2眼，2条泪小管）观察到泪小管下部有一些管腔样结构。18例（18眼，18条泪小管）既往有泪小管裂伤的患者中，仅14例（14眼，14条泪小管）检测到泪小管鼻侧的裂伤端。
结论
UBM可用于评估泪小管疾病，可为泪小管疾病的诊断提供影像学依据。
