Methods: Multicentre retrospective cohort study encompassing five tertiary centres in the UK. Patients presenting with acute postoperative endophthalmitis with at least 4 weeks follow-up were included.

Analysing the translatability of macular hole size measurements between high-density horizontal and radial OCT scan patterns.

Objective: To assess the interchangeability of minimum linear diameter (MLD) macular hole (MH) size measurements in high-density horizontal and radial scan modes in optical coherence tomography (OCT).

Methods And Analysis: 60 patients with a MH had repeat high-density OCT volume scans in a horizontal (30 µm interscan-spacing) and a radial (angular 3.75° interscan-spacing) mode, and the MLD was measured by five raters.

Noninfectious Intraocular Inflammation After Intravitreal Aflibercept.

Importance: Aflibercept, 8 mg, is an anti-vascular endothelial growth factor (VEGF) formulation for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME). While clinical trials report a comparable safety profile as aflibercept, 2 mg, clinical practice setting (so-called real-world) data on the incidence of intraocular inflammation (IOI) should be of value.

Objective: To determine the clinical practice setting incidence of IOI after intravitreal injection of aflibercept, 8 mg, for nAMD and DME.

Extended phenotypic spectrum of benign yellow dot maculopathy.

Background: To present the morphological and functional characteristics of individuals with benign yellow dot maculopathy (BYDM).

Methods: Assessments included ocular examinations, best-corrected visual acuity (BCVA) testing, optical coherence tomography (OCT), blue-light fundus autofluorescence (BAF), and near-infrared autofluorescence (NIR-AF). First degree family members were also examined whenever available.

Long term analysis of microbiological isolates and antibiotic susceptibilities in acute-onset postoperative endophthalmitis: a UK multicentre study.

Objectives: To review the trend of microbial isolates for postoperative endophthalmitis (POE) in the United Kingdom (UK) and determine the sensitivity to current empirical intravitreal antibiotic treatment.

Methods: We conducted a long term multicentre consecutive case review of POE across 3 geographically distant tertiary eye centres in the UK: Sunderland Eye Infirmary (2000-2022), Oxford Eye Hospital (2016-2022), and Southampton General Hospital (2016-2022). Data on the microbial samples taken and results including sensitivities to antibiotics agents given were collected.

[N-Acetylcysteine (NAC) for Retinitis pigmentosa].

Retinitis pigmentosa (RP) is a genetically mediated degenerative retinal disease that leads to progressive photoreceptor degeneration and, ultimately, blindness. Oxidative stress plays a central role in the pathogenesis of RP. This study examines the effect of N-acetylcysteine (NAC), an antioxidant and glutathione precursor, on the disease progression in RP patients.

De novo and inherited dominant variants in U4 and U6 snRNAs cause retinitis pigmentosa.

The U4 small nuclear RNA (snRNA) forms a duplex with the U6 snRNA and, together with U5 and ~30 proteins, is part of the U4/U6.U5 tri-snRNP complex, located at the core of the major spliceosome. Recently, recurrent variants in the U4 RNA, transcribed from the gene, and in at least two other genes were discovered to cause neurodevelopmental disorder.

Differential Diagnosis of Age-Related Macular Degeneration.

A diagnosis of age-related macular degeneration (AMD) may have a significant impact on a patient's life. Therefore, it is important to consider differential diagnoses, as these can differ considerably from AMD regarding prognosis, inheritance, monitoring and therapy. Differential diagnoses include other macular diseases with drusen, drusen-like changes, monogenic retinal dystrophies, as well as a wide range of other, often rare macular diseases.

Painful vision loss during air travel after vitrectomy with air tamponade: a case report.

Background: While the potentially hazardous effects of intraocular perfluorocarbon gases during air travel have been recognized, the equivalent risk of intraocular air tamponade is less known and has, to the best of our knowledge, not been reported yet.

Case Presentation: A 52-year-old white female experienced a complete loss of vision and pain in her left eye during air travel following pars plana vitrectomy with air tamponade. Clinical and multimodal imaging findings only a few hours after emergency landing indicated a transient central retinal artery occlusion due to a significant increase in intraocular pressure during the flight.

OPTICAL COHERENCE TOMOGRAPHY FEATURES ASSOCIATED WITH VITREOMACULAR TRACTION RELEASE AND MACULAR HOLE SIZE PROGRESSION FOLLOWING TREATMENT WITH OCRIPLASMIN.

Purpose: To evaluate OCT features for vitreomacular traction (VMT) release and change in macular hole (MH) size after treatment with ocriplasmin.

Methods: Patients who had undergone treatment with ocriplasmin for VMT with or without MH ≤400 µm were included. The main outcomes were VMT release and changes in minimum linear diameter MH size at 4 weeks in MHs that persisted.

Real-world six-month outcomes in patients switched to faricimab following partial response to anti-VEGF therapy for neovascular age-related macular degeneration and diabetic macular oedema.

Background: Landmark studies reported on faricimab efficacy and safety predominantly in treatment naïve patients, but outcomes following switch from other anti-VEGF therapies are lacking. We evaluated patients switched to faricimab who had previously shown a partial response to other anti-VEGF injections for neovascular age-related macular degeneration (nAMD) and diabetic macular oedema (DMO).

Methods: Retrospective study at the Oxford Eye Hospital.

Multifocal Vitelliform Paravascular Retinopathy (MVPR): A New Disorder in the Vitelliform Spectrum.

Purpose: To describe a new retinal phenotype characterized by bilateral, multifocal, subretinal vitelliform lesions along the vascular arcades that we refer to as multifocal vitelliform paravascular retinopathy (MVPR).

Design: Observational case series.

Methods: Multimodal retinal imaging including color fundus photography, fundus autofluorescence and cross sectional and en-face optical coherence tomography was performed to evaluate and characterize the lesions of MVPR.

Greener intravitreal injections: a narrative review.

Healthcare services are significant contributors to climate change. Ophthalmology, by virtue of the volume of appointments and procedures it generates, is thought to play a major role in this regard. Intravitreal injections (IVI) are a commonly performed ophthalmological procedure to treat patients with conditions such as macular neovascularisation secondary to neovascular age-related macular disease or myopia, diabetic macular oedema, and retinal vein occlusions.

Intravitreal Injections: Improving Sustainability by Reducing Clinical Waste.

Background: Intravitreal injections are one of the most commonly performed ophthalmic procedures. It is estimated that over 1 million intravitreal injections are performed in Germany annually. The aim of this study was to quantify the waste and carbon footprint associated with single-use injection sets, and to establish a waste reduction strategy.

Rescue of cone and rod photoreceptor function in a CDHR1-model of age-related retinal degeneration.

Age-related macular degeneration (AMD) is the most common cause of untreatable blindness in the developed world. Recently, CDHR1 has been identified as the cause of a subset of AMD that has the appearance of the "dry" form, or geographic atrophy. Biallelic variants in CDHR1-a specialized protocadherin highly expressed in cone and rod photoreceptors-result in blindness from shortened photoreceptor outer segments and progressive photoreceptor cell death.
