Introduction: Neovascular age-related macular degeneration is a global public-health concern, associated with a considerable burden to individuals, healthcare systems, and society. The objective of this study was to understand different perspectives on the challenges associated with the clinical management of neovascular age-related macular degeneration, which could elucidate measures to comprehensively improve clinical care and outcomes.

Methods: A survey was carried out of patients with neovascular age-related macular degeneration, their providers, and clinic staff in 77 clinics across 24 countries on six continents, from a diverse range of healthcare systems, settings, and reimbursement models.

Introduction: In contrast with patients receiving therapy for retinal disease during clinical trials, those treated in routine clinical practice experience various challenges (including administrative, clinic, social, and patient-related factors) that can often result in high patient and clinic burden, and contribute to suboptimal visual outcomes. The objective of this study was to understand the challenges associated with clinical management of diabetic macular edema from the perspectives of patients, healthcare providers, and clinic staff, and identify opportunities to improve eye care for people with diabetes.

Methods: We conducted a survey of patients with diabetic macular edema, providers, and clinic staff in 78 clinics across 24 countries on six continents, representing a diverse range of individuals, healthcare systems, settings, and reimbursement models.

Article Synopsis
  • - The study investigates the characteristics of the vitreous in healthy children aged 2-12 using advanced imaging techniques, finding that punctate hyperreflective vitreous opacities (PHVO) are common in this age group.
  • - Among 154 pediatric eyes and 76 adult eyes analyzed, 100% of children presented with PHVO compared to 73% of adults, highlighting a significant difference in prevalence.
  • - Results suggest that understanding these typical vitreous features in children can improve the accuracy of OCT interpretations, reducing the risk of misdiagnoses in pediatric patients.

Practice patterns for neovascular age-related macular degeneration (nAMD) have evolved from the landmark registration trials of vascular endothelial growth factor (VEGF) inhibitors. Non-monthly regimens like treat-and-extend (T&E) have become popular due to their effectiveness in clinical practice. T&E regimens attempt to limit the burden of visits and treatments by allowing progressively longer treatment intervals, but in so doing, are potentially associated with the expense of treating quiescent disease.

Article Synopsis
  • The study evaluates the pharmacokinetics, safety, and optimal dosages of intravitreal agents in eyes filled with silicone oil, while addressing challenges of treatment administration.
  • Findings suggest that while anti-VEGF agents have similar half-lives in silicone oil-filled eyes, most evidence is derived from case reports and small studies, with standard dosages recommended for drugs like bevacizumab being the most supported.
  • The research emphasizes the importance of close monitoring for side effects, with specific guidance on the use of various intravitreal medications, including steroids, antivirals, and antibiotics.

Purpose: The approach to managing patients with retinal vein occlusion (RVO) and cystoid macular edema (CME) with good initial visual acuity (VA) better than 6/12 has not been investigated. This study aimed to evaluate functional and anatomical outcomes of intravitreal treatment and observation in patients with CME due to RVO, who presented with good initial VA. Methods: Multicenter retrospective cohort study.

Purpose: To understand subfoveal neurosensory detachment flattening and observe (SNF-Ob) strategy and its relationship with visual acuity in the management of centre-involved diabetic macular oedema (Ci-DMO).

Methods: This was a multicentric retrospective observational study. We reviewed data of 188 eyes of 130 patients who presented with Ci-DMO with subfoveal neurosensory detachment (NSD) and treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents or steroids.

Article Synopsis
  • * Recent treatments aim to slow the progression of GA by reducing lesion growth on the retina, potentially preserving vision.
  • * Avacincaptad pegol (ACP), an FDA-approved complement component 5 inhibitor, has been extensively studied in clinical trials and shows promise in decreasing the risk of severe vision loss in GA patients.

Eyelid blepharoplasty, including lower eyelid blepharoplasty, are among the most common aesthetic surgeries recently performed. In contrast to upper eyelid blepharoplasty, lower eyelid blepharoplasty is a surgery with mostly an aesthetic indication, in which patients bear all associated costs, and their expectations rise accordingly. Nevertheless, the complexity of the anatomy, the differences in the aging processes of the face and eyelids between patients, the diversity of surgical methods, and the expectations gap make the surgery more challenging in comparison to upper eyelid blepharoplasty.

Objective: To evaluate visual outcomes after switching from bevacizumab to ranibizumab or aflibercept in patients with macular edema (ME) secondary to branch retinal vein occlusion (BRVO).

Design: A retrospective, multi-center, observational study.

Participants: Patients diagnosed with BRVO and were treated with at least 3 bevacizumab injections, before anti VEGF switch.

Background: Ophthalmic microscopes have been crucial in visualizing surgical fields, but their limitations in enhancing the surgical view through digital image processing have prompted the development of digital surgical microscopes. The Beyeonics One microscope, a novel digital microscope, offers ophthalmic surgeons a 3D visualization platform and an augmented reality (AR) surgical headset, potentially improving surgical decision-making and outcomes. While its initial use has been described in cataract and corneal surgeries, its application in vitreoretinal surgery remains relatively unexplored.

Central serous chorioretinopathy (CSC) is a relatively common disease that causes vision loss due to macular subretinal fluid leakage and it is often associated with reduced vision-related quality of life. In CSC, the leakage of subretinal fluid through defects in the retinal pigment epithelial layer's outer blood-retina barrier appears to occur secondary to choroidal abnormalities and dysfunction. The treatment of CSC is currently the subject of controversy, although recent data obtained from several large randomized controlled trials provide a wealth of new information that can be used to establish a treatment algorithm.

Geographic atrophy (GA) is an advanced and irreversible form of age-related macular degeneration (AMD). Chronic low grade inflammation is thought to act as an initiator of this degenerative process, resulting in loss of photoreceptors (PRs), retinal pigment epithelium (RPE) and the underlying choriocapillaris. This review examined the challenges of clinical trials to date which have sought to treat GA, with particular reference to the successful outcome of C3 complement inhibition.
