Article Synopsis
- The study aimed to assess the effectiveness of measuring tear meniscus height (TMH) using anterior segment optical coherence tomography (AS-OCT) for diagnosing lacrimal passage disorder (LPD) in cataract surgery patients.
- Out of 66 patients, only 12 (9.4%) had LPD, and those with LPD had a significantly higher average TMH compared to those without the disorder.
- The optimal TMH cutoff value for detecting LPD was found to be 401.0 μm, demonstrating a sensitivity of 58.3% and specificity of 83.0%, indicating AS-OCT's usefulness in preoperative assessments.
Purpose: To evaluate the association of tear meniscus height (TMH) with clinical outcomes of patients who underwent endonasal dacryocystorhinostomy.
Methods: We recruited 304 patients from two institutes. The TMH was measured using anterior segment optical coherence tomography before surgery.
Purpose: To report two cases of nasolacrimal duct obstruction (NLDO) caused by orbital fracture reconstruction with an implant successfully treated with endoscopic dacryocystorhinostomy (EnDCR).
Observations: Two patients presented with NLDO after orbital fracture reconstruction with an implant. Case 1 was a 67-year-old female.
Pathogens including autoantigens all failed to induce systemic lupus erythematosus (SLE). We, instead, studied the integrity of host's immune response that recognized pathogen. By stimulating TCR with an antigen repeatedly to levels that surpass host's steady-state response, self-organized criticality, SLE was induced in mice normally not prone to autoimmunity, wherein T follicular helper (Tfh) cells expressing the guanine nucleotide exchange factor DOCK8 on the cell surface were newly generated.

Methods: We reviewed the medical records of 498 patients (521 eyes) diagnosed with CNLDO between January 2011 and November 2013. Of these, 54 eyes met the eligibility criteria and underwent probing with a dacryoendoscope.
Purpose: To evaluate the surgical outcome of dacryocystorhinostomy (DCR) by measuring the tear meniscus, using optical coherence tomography and rebamipide ophthalmic suspension.
Methods: Patients with nasolacrimal obstruction and chronic dacryocystitis who were scheduled for an endonasal DCR underwent tear meniscus examinations before and 2 months after surgery. Vertical scans of the inferior menisci were performed before and at 1, 3, 5, 7, and 10 minutes after the instillation of rebamipide ophthalmic suspension.
