Coxsackievirus A24 causing acute conjunctivitis in a 2023 outbreak in Vietnam.

Int J Infect Dis

September 2024

Francis I. Proctor Foundation, University of California, San Francisco, USA; Department of Ophthalmology, University of California, San Francisco, USA.

Objectives: To determine the associated pathogen during the 2023 conjunctivitis outbreak in Vietnam METHODS: RNA-sequencing was used to identify pathogens before and during the outbreak.

Results: 24 patients with infectious conjunctivitis between March and October 2023 from Hai Yen Vision Institute in Vietnam were swabbed. Coxsackievirus A24v was the most common pathogen identified.

 Ophthalmic surgeons are at an increased risk for musculoskeletal disorders resulting from ophthalmology-specific routines and equipment, which have become widely associated with poor posture. The purpose of this study was to observe the effect that a commercially available posture trainer, Upright Go, can have on the improvement of posture of ophthalmic surgeons.  Eight ophthalmologists-in-training were studied over a period of 4 weeks during their surgical rotations between September 2020 and June 2021.

Purpose: To identify anatomic endpoints altered by intravitreal ranibizumab in central retinal vein occlusion (CRVO) to determine any potential underlying disease modification that occurs with anti-vascular endothelial growth factor (anti-VEGF) therapy beyond best-corrected visual acuity and central optical coherence tomography outcomes.

Methods: A post hoc analysis of a double-masked, multicenter, randomized clinical trial was performed. A total of 392 patients with macular edema after CRVO were randomized 1:1:1 to receive monthly intraocular injections of 0.

Purpose: To evaluate the association between ellipsoid zone (EZ) on spectral domain optical coherence tomography (SD-OCT) and visual acuity letter score (VALS) in participants with retinal vein occlusion in the Study of Comparative Treatments for Retinal Vein Occlusion 2.

Methods: SD-OCT scans of 362 participants were qualitatively assessed at baseline and months 1, 6, 12, and 24 for EZ status as normal, patchy, or absent. The thickness of EZ layer in the central subfield was also obtained using machine learning.

Purpose: To evaluate the association between baseline demographic and spectral domain OCT (SD-OCT) features with visual acuity (VA) in the Study of COmparative Treatments for REtinal Vein Occlusion 2 (SCORE2) over 2 years.

Design: Post hoc analysis of prospective clinical trial data.

Participants: A total of 362 SCORE2 participants with macular edema secondary to central retinal (CRVO) or hemiretinal vein occlusion (HRVO).

Background And Objective: To develop a semi-automated, machine-learning based workflow to evaluate the ellipsoid zone (EZ) assessed by spectral domain optical coherence tomography (SD-OCT) in eyes with macular edema secondary to central retinal or hemi-retinal vein occlusion in SCORE2 treated with anti-vascular endothelial growth factor agents.

Methods: SD-OCT macular volume scans of a randomly selected subset of 75 SCORE2 study eyes were converted to the Digital Imaging and Communications in Medicine (DICOM) format, and the EZ layer was segmented using nonproprietary software. Segmented layer coordinates were exported and used to generate en face EZ thickness maps.

Purpose: To summarize the results of a consensus meeting aimed at defining terminology for widefield imaging across all retinal imaging methods and to provide recommendations for the nomenclature used to describe related images.

Design: An international panel with expertise in retinal imaging was assembled to define consensus terminology for widefield imaging and associated terminology.

Participants: A panel of retina specialists with expertise in retinal imaging.

Purpose: We determine whether haptic feedback improves surgical performance and outcome during simulated a preretinal membrane peeling procedure.

Methods: A haptic-enabled virtual reality preretinal membrane peeling simulator was developed using a surgical cockpit with two multifinger haptic devices. Six subjects (three trained retina surgeons and three nonsurgeons) performed the preretinal membrane peeling surgical procedure using two modes of operation: visual and haptic feedback, and visual feedback only.
