This study aimed to examine the rate of symptomatic improvement of congenital nasolacrimal duct obstruction (CNLDO) in Japanese infants treated with conservative management within the 1st year of age. Thirty-five lacrimal ducts in 27 patients diagnosed with CNLDO were included in the study. During the observational period, lacrimal ducts were massaged. As well, antibiotic eye drops, to be administered 4 times a day, were sometimes prescribed for obvious conjunctivitis. Two lacrimal ducts in 2 patients were probed before the 1st year of age because of dacryocystitis or severe blepharitis; these patients were included in the unimproved group. Twenty-nine lacrimal ducts in 21 patients resolved during the period (82.9%); with 16 lacrimal ducts resolving before six months of age. Therefore, a comparatively high percentage of resolution for CNLDO (82.9%) following conservative management was shown before the 1st year of age in Japanese infants.

Morphological analysis of lacrimal punctum using anterior segment optical coherence tomography in different age groups.
Indian J Ophthalmol
February 2025
Department of Orbit and Oculoplasty, Sankara Eye Hospital, Coimbatore, Tamil Nadu, India.
Purpose: To evaluate the lacrimal punctal changes in different age groups using anterior segment optical coherence tomography (AS-OCT).
Methods: A cross-sectional observational study was conducted between January 2023 and January 2024 including healthy subjects between 20 and 80 years. The selected eyes from healthy patients were divided into four age groups (21-35 years, 36-50 years, 51-65 years, 66-80 years), and lower lacrimal puncta were analyzed using AS-OCT.

Purpose: To investigate the effect of S-100 absorbable hemostatic patch coverage on anastomotic mucosa in endonasal endoscopic dacryocystorhinostomy (En-DCR).
Methods: Two hundred and twenty-six patients with unilateral chronic dacryocystitis (CD) were randomly divided into two groups in a randomized controlled trial: the S-100 absorbable hemostatic patch group (group A) and the control group (group B). All patients underwent En-DCR.

Background: Epiphora and secondary ocular surface damage are increasingly impairing the quality of life of people, particularly elderly women. We aimed to investigate the changes in tear cytokine and lactoferrin levels in postmenopausal women with primary acquired nasolacrimal duct obstruction (PANDO) complicated with obstructed meibomian gland dysfunction (OMGD) and preliminary explore the pathological mechanisms of OMGD in patients with PANDO.
Methods: The prospective study involved 43 and 41 postmenopausal women with and without PANDO, respectively.
S100A8/A9 Promotes Dendritic Cell-Mediated Th17 Cell Response in Sjögren's Dry Eye Disease by Regulating the Acod1/STAT3 Pathway.

Purpose: To investigate the role of S100A8/A9 in the pathogenesis of Sjögren's dry eye disease (SjDED) and explore its potential mechanism of action.
Methods: S100A8/A9 expression was determined by western blot and quantitative real-time polymerase chain reaction (qRT-PCR). Tear secretion, corneal fluorescein staining, and hematoxylin and eosin staining were used to evaluate the effect of paquinimod, a S100A8/A9 inhibitor, on dry eye disease in nonobese diabetic (NOD) mice.
