目的评价超声生物显微镜（UBM）在泪小管疾病检查中的应用，探讨泪小管疾病状态下的超声生物显微镜图像特征。方法选取60例（63眼，69小管）泪小管疾病患者，其中慢性泪小管炎32例（32眼，32小管），既往泪小管撕裂18例（18眼，18小管），先天性泪小管缺失9例（12眼，18小管），泪小管肿块1例（1眼，1小管）。使用UBM对患者进行检查，并记录UBM图像的疾病特异性特征。结果慢性小管炎患者泪小管超声成像显示泪小管腔明显扩张。泪小管部分扩张腔内可见点状中等回声信号。9例先天性泪小管缺失患者（12眼，18小管）中2例（2眼，2小管）可见泪小管下腔样结构。在18例（18眼，18小管）既往泪小管撕裂的患者中，仅14例（14眼，14小管）在泪小管鼻侧发现撕裂端。结论UBM可用于泪小管疾病的评价，为泪小管疾病的诊断提供影像学依据。
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.
