“…As for the various LDS conditions, the biopsy specimens could be obtained by scraping the lesion by sheath advancement of DE [ 70 ]. From the patients with recurrent NDO, stratified epithelium and a mixed inflammatory cell infiltrates were identified suggesting squamous metaplasia of the usual respiratory epithelium [ 70 ]. Similar findings were also reported a subepithelial mixed inflammatory cell and fibroblast infiltration in the early phase, and squamous metaplasia and subepithelial fibrosis in the chronic phase ( Fig.…”

Purpose: A systematic review of the literature on diagnostic and therapeutic indications, techniques, and complications of dacryoendoscopy (DE) was performed. Methods: The authors performed a PubMed search of articles published in English on DE. Data was collected and classified according to the categories of the disease. And the clinical outcomes and limitations were particularly analyzed.Results: The lacrimal drainage system from the canaliculus to the inferior meatus could be examined based on the specific anatomical features by DE. The canalicular mucosa is smooth and brightly colored, the lacrimal sac shows covering mucosa with good vascularization and the nasolacrimal duct is lined with bright tubular mucosal folds. DE allows direct visualization of the detailed internal condition of the lacrimal disorders, to directly diagnose the site of obstruction with accuracy and address the causes and recanalize the lacrimal drainage system using assisted micro lacrimal surgical instruments in the tearing patients. Conclusions: Better visualization of the lacrimal canal with DE improves the understanding of physiology and precise identification of the obstructing lesions, both of which are the key to a comprehensive management for the tearing patients.

“…The dacryoendoscope was inserted from each punctum; stenotic or occlusion sites were opened and enlarged by direct endoscopic probing. If stenosis or occlusion tissue could not be efficiently dealt with, sheath-guided endoscopic probing was performed [13]. Briefly, lacrimal passage stenosis or occlusion was released using a 20-G needle sheath on the tip of the endoscope.…”

Feasibility of Strip Meniscometry for Tear Volume Evaluation in Lacrimal Passage Obstruction

Strip meniscometry tube (SMTube) is useful for assessing tear volume in dry eye disease. We performed an in vitro and a clinical study to examine whether the SMTube can also be used to evaluate tear quantity in lacrimal passage obstruction (LPO). In vitro experiments showed that the SMTube value and the amount of water absorption were significantly correlated (R2 = 0.816, p = 0.0008), but the measured value peaked when 4 μL was absorbed. In the clinical study, 12 eyes of 9 LPO patients and 17 eyes of 17 healthy control subjects were included. The patients’ SMTube values were significantly higher than those of the control subjects (p < 0.05). The SMTube value significantly decreased after silicon tube intubation (p < 0.05). Tear meniscus height (TMH) and area (TMA), measured by anterior segment optical coherence tomography, exhibited a significant positive correlation with the SMTube value (TMH, p < 0.001, R2 = 0.396; TMA, p < 0.001, R2 = 0.366). Moreover, the SMTube value significantly correlated positively with the subjective symptom of epiphora (p = 0.012, R2 = 0.255). Thus, SMTube was useful for evaluating the tear volume and therapeutic effects in patients with LPO.
