Abstract:
Objective To observe the ultrasound biomicroscopy(UBM)findings of lacrimal canaliculitis.Methods Totally 35 patients with single eye lacrimal canaliculitis who underwent surgical treatment were retrospectively enrolled,including 3 cases of simple superior lacrimal tubule abnormalities,19 cases of simple inferior lacrimal tubule abnormalities and 13 cases with both superior and inferior lacrimal tubules.UBM data and postoperative laboratory examination results were comparatively analyzed.Results The detection rate of UBM for lacrimal canaliculitis was 100％.Abnormal coenobium-like structures in lacrimal tubule were characterized by elliptical or irregular low echo,with unclear boundaries and uneven internal echo,some with punctate high echoes,while polyps presented as oval or strip-shaped high echo with clear boundaries and uniform internal echoes in UBM.UBM findings of tumor like hyperplasia were similar to abnormal coenobium-like structures but with relatively uniform internal echoes.Sulfur particles extracted from lacrimal tubule revealed no fungi in 35 cases by postoperation pathology,while actinomycete was observed in 24 cases,with UBM finding of abnormal coenobium-like structures and punctate high echoes.Conclusion UBM findings of lacrimal canaliculitis had certain characteristics.Coenobium-like structures and punctate high echoes in lacrimal tubule could be observed after infection of actinomycete.
