Leber hereditary optic neuropathy (LHON) is a rare mitochondrial genetic disorder characterized by painless acute or subacute vision loss that develops during adolescence. Clinicians should know how to identify potential LHON and when to refer patients to a neuro-ophthalmologist for diagnosis and treatment. This case highlights the value of a thorough family history in ED patients.

Choroid neovascularization (CNV) is a distinct type of age-related macular degeneration (AMD) with a poor prognosis and responsible for the majority of vision loss in the elderly population. The laser-induced CNV model is a well-established animal model frequently used to study CNV. In this study, we performed an integrated analysis of metabolomic and transcriptomic data from CNV samples, utilizing multiple approaches including single-sample gene set enrichment analysis (ssGSEA), correlation analysis, and weighted gene co-expression network analysis (WGCNA), alongside various bioinformatics platforms, to identify key metabolic and immune signatures and to investigate their interplay during angiogenesis.

Introduction: In diabetics, glucagon-like peptide 1 (GLP-1) receptor agonists (RA) may protect against microvascular alterations and oxidative stress, both of which have been implicated in glaucoma. Multiple studies suggest a possible relation between GLP-1 RA use and the development of glaucoma. This study performs a systematic review of the literature regarding the incidence of glaucoma development in type 2 diabetes patients treated with GLP-1 receptor agonists compared to a control group.

The aim of this article has been, on the one hand, to describe the use of MSICS (manual small incision cataract surgery) for the management of cataracts, especially mature ones, in relation to its particular utility in the field of humanitarian campaigns, for which a description of the MSICS technique has been made, subsequently a review of the available scientific literature has been carried out to verify the results of this technique in comparison with phacoemulsification and extracapsular surgery and to describe the importance of teaching this technique to all cataract surgeons, especially the ones participating in humanitarian campaigns. According to what has been found, MSICS is an excellent surgical technique and according to current evidence it seems to be the choice over phacoemulsification and/or the classic extracapsular technique in hyper mature cataracts, especially in the field of humanitarian campaigns, due to its lower rate of complications and the improvement in visual acuity obtained. According to the studies found, it would be possible for the experienced ophthalmologic surgeon to implement this technique since the learning curve is short.

Background: We aimed to describe a 2-year outcome of eyes managed by practitioners benchmarked using a funnel plot by their frequency of treatment using vascular endothelial growth factor (VEGF) inhibitors for naive retinal vein occlusion (RVO).
Methods: A multicentre, international, observational study of 29 doctors in 12 countries managing 1110 eyes with RVO commencing VEGF inhibitors between 1 January 2012-2022 tracked in the Fight Retinal Blindness! registry.
Results: We identified 3 outlying 'intensive' practitioners (managing 350/1110 eyes [32%]), 22 'typical' practitioners (604/1110, [54%]) and 4 outlying 'relaxed' practitioners (156/1110, [14%]) with respective 24-month outcomes in Branch and Central RVO including the primary outcome, mean adjusted change in visual acuity (VA) in BRVO: +16.

Age-related macular degeneration (AMD) is a chronic multifactorial degenerative eye disease and one of the leading causes of irreversible blindness worldwide. Despite extensive research, there is no consensus on the predominant pathological mechanism leading to photoreceptor death. AMD is associated with molecular and cellular disruptions that ultimately result in photoreceptor degeneration.
