Background: Whilst research and innovation is embedded within the UK's National Health Service (NHS) constitution, Doctors-in-training have little opportunity to contribute to designing, leading and recruiting into clinical trials or cohort studies. We formed the West Midlands Collaborative Ophthalmology Network for Clinical Effectiveness & Research by Trainees (The West Midlands CONCERT) and undertook a characterisation of post cataract surgery endophthalmitis as a proof-of-concept study to test the feasibility of the CONCERT model.
Methods: Doctors-in-training formed a collaborative working group to test the concept of delivering a pan-regional clinical effectiveness study across multiple hospital sites by performing retrospective analyses of post cataract endophthalmitis over a 6-year period.
Results: Overall, 157,653 cataract surgeries were performed by participating centres accredited to deliver the Royal College of Ophthalmologists training curriculum. Thirty-eight cases of post cataract endophthalmitis were identified, giving an incidence of 2.41 per 10,000 cases (0.0241%). A further 15 endophthalmitis cases presented who had surgery in non-training centres, giving a total of 53 cases. The most common organisms were S. epidermidis (14 (51.9%)) and P. aeruginosa (5 (18.5%)). Anterior-chamber and vitreous sampling yielded positive culture in 33.3% (6/18) and 50.9% (27/53), respectively. At 6 months follow-up, 19 (51.4%) patients achieved visual acuities of ≤0.5 LogMAR. Repeat intravitreal injections (11 (20.8%)) and vitrectomy (n = 22 (41.5%)) were not associated with better outcomes.
Conclusions: Using post cataract endophthalmitis as a pilot cohort, this study highlights the feasibility of using the CONCERT model for studies across multiple sites. A UK-CONCERT could provide a powerful infrastructure enabling characterisation of patient cohorts and a platform for high-quality interventional studies, improving patient care.

Visually significant ocular decompression retinopathy following laser peripheral iridotomy in a patient with primary acute angle-closure glaucoma.
Am J Ophthalmol Case Rep

Department of Ophthalmology, Ross Eye Institute, University at Buffalo, 1176 Main Street, Buffalo, NY, 14209, United States.
Purpose: We report a single case of ocular decompression retinopathy (ODR) following neodymium-doped yttrium aluminum garnet laser peripheral iridotomy (Nd:YAG LPI) for primary acute angle-closure glaucoma associated with delayed visual recovery secondary to optic nerve head edema and macular thickening.
Observations: A 56-year-old female patient presented to the emergency department with primary acute angle-closure glaucoma. After topical and IV therapy did not improve intraocular pressure (IOP), an Nd:YAG LPI was performed.
Demographic Profile and Clinical Characteristics of Fuchs Endothelial Corneal Dystrophy in Thai Patients: A Retrospective Cohort in a Tertiary Referral Center.

Purpose: To describe the demographic profile, clinical characteristics, and treatment trends of Fuchs endothelial corneal dystrophy (FECD) in Thai patients, reflecting the evolving landscape of corneal transplantation in this region.
Patients And Methods: This retrospective cohort study included 900 patients (1,743 eyes) diagnosed with FECD at a tertiary referral center in Thailand between January 2017 and June 2023. Demographic, clinical, and surgical data were analyzed, focusing on best-corrected visual acuity (BCVA), central corneal thickness (CCT), endothelial cell density (ECD), surgical interventions, and graft survival rate.
Cognitive Trajectory Before and After Cataract Surgery: A Population-Based Approach.

Department of Anesthesia and Perioperative Care, University of California, San Francisco, San Francisco, California, USA.
Background: Cataract surgery is the most common surgical procedure performed for older US adults. Cataracts are associated with poor cognition and higher rates of dementia, but whether cataract surgery improves cognition for US older adults is not known. We examined the relationship between cataract surgery and long-term change in cognition in the Health and Retirement Study, a population-based study of older US adults linked with Medicare billing data.
