To review the evolution of terminology describing the classification of lesions in neovascular age-related macular degeneration (nAMD) based on retinal imaging technologies. A review of the current and historical literature on imaging-guided classification of neovascularization in nAMD was performed. Imaging-guided classification of neovascularization in nAMD facilitates understanding of the pathological mechanisms and disease progression.

Article Synopsis
  • - This study highlights the anatomy of the carpal tunnel and identifies four potentially dangerous anatomical variations that could lead to nerve or vessel injuries during minimally invasive carpal tunnel release surgeries.
  • - Researchers examined the carpal tunnel in 104 wrists from 52 body donors and measured distances between critical neurovascular structures like the median nerve and ulnar artery to determine their proximity.
  • - The authors recommend using preoperative ultrasound assessments to help minimize the risk of neurovascular injuries, particularly in patients with these identified anatomical variations.

Purpose: The Phase 3 Mylight study was designed to confirm clinical equivalence of proposed biosimilar aflibercept (SOK583A1; Sandoz [proposed biosimilar aflibercept, SDZ-AFL]) to its reference biologic (Eylea; Regeneron Pharmaceuticals, Inc; Bayer AG [reference aflibercept, Ref-AFL]).

Method: Mylight was a prospective, double-masked, 2-arm, parallel Phase 3 study. Participants with neovascular age-related macular degeneration were randomized 1:1 to receive eight injections of SDZ-AFL (n = 244) or Ref-AFL (n = 240) over 48 weeks.

Large-conductance, calcium-activated potassium channels (BK channels) and the Na/K-ATPase are expressed universally in vascular smooth muscle. The Na/K-ATPase may act via changes in the intracellular Ca concentration mediated by the Na/Ca exchanger (NCX) and via Src kinase. Both pathways are known to regulate BK channels.

p53 is a crucial tumor suppressor in vertebrates that is frequently mutated in human cancers. Most mutations are missense mutations that render p53 inactive in suppressing tumor initiation and progression. Developing small-molecule drugs to convert mutant p53 into an active, wild-type-like conformation is a significant focus for personalized cancer therapy.

Restricting the localization of evolutionarily conserved histone H3 variant CENP-A to the centromere is essential to prevent chromosomal instability (CIN), an important hallmark of cancers. Overexpressed CENP-A mislocalizes to non-centromeric regions and contributes to CIN in yeast, flies, and human cells. Centromeric localization of CENP-A is facilitated by the interaction of Mis18β with CENP-A specific chaperone HJURP.

Understanding the normal function of the Huntingtin (HTT) protein is of significance in the design and implementation of therapeutic strategies for Huntington's disease (HD). Expansion of the CAG repeat in the gene, encoding an expanded polyglutamine (polyQ) repeat within the HTT protein, causes HD and may compromise HTT's normal activity contributing to HD pathology. Here, we investigated the previously defined role of HTT in autophagy specifically through studying HTT's association with ubiquitin.

Objective: The fragility index (FI) of a meta-analysis evaluates the extent that the statistical significance can be changed by modifying the event status of individuals from included trials. Understanding the FI improves the interpretation of the results of meta-analyses and can help to inform changes to clinical practice. This review determined the fragility of ophthalmology-related meta-analyses.

Centromeric localization of evolutionarily conserved CENP-A (Cse4 in Saccharomyces cerevisiae) is essential for chromosomal stability. Mislocalization of overexpressed CENP-A to noncentromeric regions contributes to chromosomal instability in yeasts, flies, and humans. Overexpression and mislocalization of CENP-A observed in many cancers are associated with poor prognosis.

Purpose: Complications associated with intravitreal anti-VEGF therapies are reported inconsistently in the literature, thus limiting an accurate evaluation and comparison of safety between studies. This study aimed to develop a standardized classification system for anti-VEGF ocular complications using the Delphi consensus process.

Design: Systematic review and Delphi consensus process.

Aim: The study assessed mothers, children and adolescents' health (MCAH) outcomes in the context of a Primary Health Care (PHC) project and associated costs in two protracted long-term refugee camps, along the Thai-Myanmar border.

Background: Myanmar refugees settled in Thailand nearly 40 years ago, in a string of camps along the border, where they fully depend on external support for health and social services. Between 2000 and 2018, a single international NGO has been implementing an integrated PHC project.

The F-box domain is a highly conserved structural motif that defines the largest class of ubiquitin ligases, Skp1/Cullin1/F-box protein (SCF) complexes. The only known function of the F-box motif is to form the protein interaction surface with Skp1. Here we show that the F-box domain can function as an environmental sensor.

Article Synopsis
  • - The GATHER trials aimed to assess how reducing geographic atrophy (GA) lesion growth affects visual acuity, using randomized, double-masked, and sham-controlled methods with participants aged 50 or older.
  • - In these trials, patients were randomized to receive either 2 mg of avacincaptad pegol (ACP) or a sham treatment, with results showing a lower percentage of vision loss in those treated with ACP at 12 months compared to the sham group.
  • - The study concluded that ACP 2 mg treatment effectively delayed the progression of vision loss and maintained eligibility for driving in patients compared to those receiving sham treatment.

Purpose: In early 2022, a fluorescein shortage occurred in the United States. To meet the standard of care for patients who required ultrawidefield fundus fluorescein angiography (UWFFA), a regimen of half-dose (250 mg) sodium fluorescein (10%) was adopted instead of the full dose (500 mg) at the Cole Eye Institute (CEI). In this paper, we compare the image quality, clinical utility, and the side-effect profile of half-dose versus full-dose fluorescein in UWFFA for a cohort of stable patients.

Article Synopsis
  • The introduction of biologic medicines that target VEGF has greatly enhanced treatment outcomes for patients with retinal diseases, but their high costs can limit access to care.
  • Biosimilars, which are cheaper alternatives that are proven to be clinically equivalent to branded agents, offer a potential solution to financial barriers in treatment.
  • Since 2022, anti-VEGF biosimilars have begun to emerge in the US ophthalmology market, prompting a review of their regulatory background, development challenges, and the implications for patient care.

Newly approved treatments for patients with geographic atrophy are changing the treatment paradigm, highlighting the need for eye care providers (ECPs) to have a set of recommendations on how to best manage GA patients. Here, we outline how to identify various stages of age-related macular degeneration including geographic atrophy (GA) by examining optimal management scenarios implicating various ECPs and reviewing treatment considerations for patients with GA. Early identification of GA will lead to optimal patient outcomes, while a standardized management scenario will reduce clinical burden among ECPs treating patients with GA.
