Introduction: The aim of this study was to describe the development of an integrative dataset, combining clinical and optical coherence tomography (OCT) imaging data by applying a deep learning (DL) algorithm for automated, objective, and comprehensive quantification of OCT scans in two large real-world datasets of eyes with neovascular age-related macular degeneration (nAMD). We further report baseline characteristics of the study population, focusing on demographics, clinical parameters, and quantitative retinal morphological features.

Methods: This retrospective study analyzed data from 5,207 eyes of 4,265 nAMD patients treated at two centers in the UK and Israel.

Objective: To establish the influence of different optical coherence tomography (OCT) biomarkers at baseline treatment on the potential response to anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular oedema (DME).

Methods: Multicentric, retrospective, case-series study in patients with DME switched to dexamethasone implant injections (DEX-i) after anti-VEGF in real clinical practice. Biomarkers analysed on OCT images at baseline included intraretinal fluid (IRF), subretinal fluid (SRF), disorganisation of retinal inner layers (DRIL), disorganisation of retinal outer layers (DROL), hyperreflective foci (HRF), hyperreflective cystoid walls (HCW), dense intraretinal cyst (DIR) and vitreomacular interface (VMI) abnormalities.

Background/objectives: To evaluate the impact of intravitreal bevacizumab (IVB) therapy on anatomical and visual outcomes in patients with macular neovascularization (MNV) secondary to chronic central serous chorioretinopathy (cCSC).

Methods: This retrospective observational study reviewed the medical records of treatment-naïve patients diagnosed with cCSC complicated by MNV and treated with IVB injections over a 5-year period. The presence of MNV was confirmed using optical coherence tomography angiography (OCTA).

Purpose: To evaluate the potency and security of Pneumatic Vitreolysis (PVL) as the primary treatment for Full-Thickness Macular Holes (FTMHs) and provide insights into patient selection criteria and procedural outcomes.

Patients And Methods: A retrospective analysis of three clinical cases presenting with FTMHs treated initially with PVL was conducted. Cases were evaluated for anatomical and functional outcomes through comprehensive ophthalmic examination and optical coherence tomography (OCT) imaging.

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 and cystoid macular edema (CME) with good initial visual acuity 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 because of retinal vein occlusion, who presented with good initial visual acuity.

Methods: Multicenter retrospective cohort study.

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.

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.
