Investigating the Relative Importance of Tear Homeostatic Signs for the Diagnosis of Dry Eye Disease.

Aim: Disease misdiagnosis is more likely if standardised diagnostic criteria are not used. This study systematically examined the effect on diagnosing dry eye disease (DED), when tests for evaluating tear film homeostasis were included/excluded from a multi-test protocol.

Method: For 1427 participants across five sites, data for the full suite of diagnostic tests defined in the Tear Film and Ocular Surface Society Dry Eye Workshop II (TFOS DEWS II) Diagnostic Methodology report algorithm were evaluated; diagnostic sensitivity was calculated when individual signs were removed, and when different combinations of signs were required.

Blink completeness and rate in dry eye disease: An investigator-masked, prospective registry-based, cross-sectional, prognostic study.

Purpose: To investigate the prognostic ability of blink rate and the proportion of incomplete blinking to predict dry eye disease diagnosis, as defined by the TFOS DEWS II criteria.

Methods: A total of 453 community residents (282 females, 171 males; mean ± SD age, 37 ± 19 years) were recruited in an investigator-masked, prospective registry-based, cross-sectional, prognostic study. Dry eye symptomology, tear film quality, and ocular surface characteristics were assessed in a single clinical session, and blink parameters evaluated by an independent masked observer.

In vitro anti-biofilm efficacy of therapeutic low dose 265 nm UVC.

Purpose: Preclinical studies have confirmed the safety and efficacy of narrowband low-intensity ultraviolet C light (UVC) in managing bacterial corneal infection. To further consolidate these findings, the present study aimed to explore in vitro anti-biofilm efficacy of low-intensity UVC light for its potential use in biofilm-related infections.

Methods: Pseudomonas aeruginosa biofilm was grown in chamber well slides for 48 h and exposed to one of the following challenges: UVC (265 nm wavelength, intensity 1.

Rhinorrhea Recurrence After Posterior Nasal Nerve Cryoablation: A Multicenter Cohort Study.

Background: Posterior nasal nerve (PNN) cryoablation improves chronic rhinitis (CR) symptoms in 70-80% of cases, including clear thin rhinorrhea (CTR). This study's purpose was to determine time to and degree of CTR recurrence following cryoablation.

Methods: A multicenter retrospective cohort study was conducted on patients who underwent PNN cryoablation to treat CR-related CTR refractory to ipratropium bromide nasal spray (IBNS).

Craniofacial Pain Locations and Outcomes After Endoscopic Sinus Surgery for Unilateral Sphenoid Sinusitis: A Multi-Institutional Study.

Introduction: Unilateral sphenoid sinus opacification on computed tomography is caused by a variety of pathologies including inflammatory and infectious sinusitis, benign and malignant tumors, and encephaloceles. The purpose of this study was to report craniofacial pain locations and outcomes in inflammatory unilateral sphenoid sinusitis (USS) patients who underwent endoscopic sinus surgery (ESS).

Methods: A multi-institutional retrospective cohort study was conducted on all adult patients who had ESS for USS from 2015 to 2022.
