BACKGROUND: Macular edema (ME) in the setting of retinal vein occlusions (RVO) is a common cause of vision loss worldwide. Anti-vascular endothelial growth factor (anti-VEGF) injections are the gold standard for ME secondary to RVO. Despite their efficacy, anti-VEGF injections carry significant burdens for patients, resulting in high rates of loss to follow-up and treatment lapses. METHODS: A sub-analysis examining the effects of a treatment lapse in RVO patients was conducted...

OBJECTIVE: Our study aims to build on our understanding of COVID-19 by detailing a comprehensive look at the prevalence of different ocular manifestations related to COVID-19 infection. DESIGN: This study is a systematic review and meta-analysis. METHODS: Eligible studies published between June 20, 2021, and May 11, 2023, were retrieved from the MEDLINE, EMBASE, and CINAHL databases as well as grey literature. Covidence was used to conduct the systematic review...

OBJECTIVE: To evaluate the success of diagnostic genetic testing in inherited retinal dystrophy (IRD) patients in the clinical setting. DESIGN: Retrospective cohort analysis. PARTICIPANTS: A total of 446 consecutive participants from diverse ethnic backgrounds living in western Canada. METHODS: Clinical information was collected from participants, including family history, and they underwent a full ophthalmic examination with chart review...

OBJECTIVE: The purpose of this research is to report on real-world anti-vascular endothelial growth factor (anti-VEGF) treatment patterns in retinal vein occlusions (RVO). DESIGN: Retrospective cohort study. PARTICIPANTS: Treatment-naive RVO patients initiating anti-VEGF injections between 2015 and 2021. METHODS: Medical records available until June 2022 were reviewed. Demographics, diagnosis, number of injections, treatment length, reason for discontinuation, and baseline and final data (e...

PURPOSE: To determine the effect of frontloading (multiple) visual field (VF) tests at the same visit for detecting mean deviation (MD) change in slowly progressive glaucoma. METHODS: This was a computer simulation study. Baseline MD (range, 0 to -12 dB) and progression rate (range, 0 to -0.4 dB/year, non-inclusive) were generated for 10,000 patients. Each patient had 6 simulated "stable" baseline VF tests. Then follow-up VFs (up to 10 years) were generated by incorporating progression rate and within-visit and between-visit variability...

BACKGROUND: Children undergoing hemispheric surgery for intractable seizures are susceptible to visual complications including strabismus. This systematic review aims to investigate the rates and characteristics of strabismus development after hemispheric surgery and evaluate clinical implications for ophthalmologic care. METHODS: A systematic search of MEDLINE, EMBASE, Cochrane, PsychINFO, and Web of Science databases was performed from database inception to May 2022...

PURPOSE: To assess the anatomic and functional outcomes in sequential and simultaneous bilateral rhegmatogenous retinal detachment (BRRD) repair. DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 218 eyes in 109 patients. METHODS: Patients diagnosed with BRRD between 2014 and 2020 at the University Centre of Ophthalmology-CHU de Québec-Laval University were reviewed. Main outcomes were single-surgery anatomic success (SSAS) and final pinhole visual acuity (PHVA) in logMARs...

PURPOSE: To assess the outcomes and failure risk factors for Kahook Dual Blade (KDB) excisional goniotomy with cataract surgery (phaco-KDB) in eyes with various glaucoma subtypes and severities. METHODS: This multisurgeon consecutive case series included glaucomatous eyes with cataract that underwent phaco-KDB and had a minimum follow-up of 12 months postoperatively. Efficacy was assessed by absolute and qualified surgical success (defined by different criteria) and changes in intraocular pressure (IOP) and antiglaucoma medication (AGM) at the last postoperative follow-up...

PURPOSE: To report a case of a retrocorneal fibrous membrane and corneal decompensation following uncomplicated phacoemulsification in an eye with pseudoexfoliative glaucoma. METHOD: Case report and literature review. RESULTS: A monocular 83-year-old female developed corneal decompensation 1 year after uncomplicated cataract extraction via phacoemulsification. She had a history of pseudoexfoliative glaucoma and had undergone 3 rounds of selective laser trabeculoplasty in the same eye 3 years prior...

BACKGROUND: Anemia has been temporally associated with idiopathic intracranial hypertension (IIH), but the relationship is uncertain because of a lack of prospective studies and because both IIH and anemia are common in young women with obesity. MATERIAL AND METHODS: This was a prospective study of consecutive patients with IIH referred to 3 neuro-ophthalmology centres between March 2021 and September 2022. All patients had a complete blood count available within 6 months of presentation...

BACKGROUND: Timely access to human expertise for affordable and efficient triage of ophthalmic conditions is inconsistent. With recent advancements in publicly available artificial intelligence (AI) chatbots, the lay public may turn to these tools for triage of ophthalmic complaints. Validation studies are necessary to evaluate the performance of AI chatbots as triage tools and inform the public regarding their safety. OBJECTIVE: To evaluate the triage performance of AI chatbots for ophthalmic conditions...
