Wide field imaging biomarkers: A different perspective.

Wide field retinal imaging has emerged as a transformative technology over the last few decades, revolutionizing our ability to visualize the intricate landscape of the retina. By capturing expansive retinal areas, these techniques offer a panoramic view going beyond traditional imaging methods. In this review, we explore the significance of retinal imaging-based biomarkers to help diagnose ocular and systemic conditions.

From Cellular to Metabolic: Advances in Imaging of Inherited Retinal Diseases.

: Inherited retinal diseases (IRDs) are a genetically complex group of disorders, usually resulting in progressive vision loss due to retinal degeneration. Traditional imaging methods help in structural assessments, but limitations exist in early functional cellular-level detection that are crucial for guiding new therapies. : This review includes a systematic search of PubMed and Google Scholar for studies on advanced imaging techniques for IRDs.

Choriocapillaris flow in two different patterns of exudative type 1 macular neovascularization.

Background: To compare the characteristics of type 1 macular neovascularization (MNV) and the surrounding choriocapillaris (CC) perfusion in patients with neovascular age-related macular degeneration (nAMD) versus those with pachychoroid neovasculopathy (PNV) using swept-source optical coherence tomography angiography (SS-OCTA).

Methods: This retrospective study included 64 treatment-naïve eyes (37 nAMD, 27 PNV) with type 1 MNV. SS-OCTA images were analysed to measure MNV area and perimeter, and CC flow deficits (FD) in five concentric rings surrounding the lesion.

Detection of Disease Features on Retinal OCT Scans Using RETFound.

Eye diseases such as age-related macular degeneration (AMD) are major causes of irreversible vision loss. Early and accurate detection of these diseases is essential for effective management. Optical coherence tomography (OCT) imaging provides clinicians with in vivo, cross-sectional views of the retina, enabling the identification of key pathological features.

Multifaceted approach to evacuating multi-level premacular hemorrhage in a case of suspected Valsalva retinopathy - a case report.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.

Methods: This is a retrospective interventional case report.

Assessment of choroidal vessels in healthy eyes using 3-dimensional vascular maps and a semi-automated deep learning approach.

To assess the choroidal vessels in healthy eyes using a novel three-dimensional (3D) deep learning approach. In this cross-sectional retrospective study, swept-source OCT 6 × 6 mm scans on Plex Elite 9000 device were obtained. Automated segmentation of the choroidal layer was achieved using a deep-learning ResUNet model along with a volumetric smoothing approach.

Predicting macular hole surgery outcomes: Integrating preoperative OCT features with supervised machine learning statistical models.

Purpose: To evaluate various supervised machine learning (ML) statistical models to predict anatomical outcomes after macular hole (MH) surgery using preoperative optical coherence tomography (OCT) features.

Methods: This retrospective study analyzed OCT data from idiopathic MH eyes at baseline and at 1-month post-surgery. The dataset was split 80:20 between training and testing.

Pharmacological adjuvants for diabetic vitrectomy surgery.

Diabetic vitrectomy is a highly intricate surgical procedure performed during the advanced stages of diabetic retinopathy (DR). It is used to treat conditions such as tractional or combined retinal detachment, vitreous hemorrhage, and subhyaloid hemorrhage, which are all severe manifestations of proliferative DR. The results of the surgery are uncertain and variable.

Inter-rater reliability in labeling quality and pathological features of retinal OCT scans: A customized annotation software approach.

Objectives: Various imaging features on optical coherence tomography (OCT) are crucial for identifying and defining disease progression. Establishing a consensus on these imaging features is essential, particularly for training deep learning models for disease classification. This study aims to analyze the inter-rater reliability in labeling the quality and common imaging signatures of retinal OCT scans.

Pentosan polysulfate sodium maculopathy: Final analysis of a prospective cohort, updated review, and association with inflammatory bowel disease.

Pentosan polysulfate sodium (PPS) maculopathy is a recently described condition of macular toxicity. We report the prevalence (15 %), the clinical characteristics, and the multimodal imaging (MMI) features of PPS maculopathy based on a final prospective analysis of a cohort of 154 subjects and highlight the association with inflammatory bowel disease (IBD). In addition, we summarize the most recent and relevant literature on PPS maculopathy.

Phacovitrectomy vs. consecutive vitrectomy for idiopathic macular holes: short and long-term outcomes and OCT image quality assessment.

Purpose: To compare short- and long-term anatomical, functional, and refractive outcomes between combined phacovitrectomy (PVS) and consecutive vitrectomy (CVS) for idiopathic macular holes (MHs). Also, to evaluate the role of preoperative optical coherence tomography (OCT) image quality in guiding surgical selection.

Methods: This retrospective study analyzed 183 phakic MH eyes operated between 2012 and 23, with patients divided into PVS and CVS groups.

Three-Dimensional Choroidal Vessels Assessment in Age-Related Macular Degeneration.

Purpose: To compare the choroidal vasculature in eyes with early- and intermediate-stage age-related macular degeneration (dAMD) and healthy using a novel three-dimensional algorithm.

Methods: Patients with dAMD and healthy controls underwent clinical examinations and swept-source optical coherence tomography scans (PlexElite-9000 device) centered on the fovea. Scans with quality scores >6 were included.

Efficacy of intravitreal faricimab therapy for polypoidal choroidal vasculopathy: A systematic review and meta-analysis.

Polypoidal choroidal vasculopathy (PCV) is an aneurismal type of macular neovascularization that show similarities with age-related macular degeneration and diseases that are part of the pachychoroid disease spectrum. Exudative changes in PCV can be treated with intravitreal anti-vascular endothelial growth factor monotherapy; however, a combination therapy with photodynamic therapy may be required. In this systematic review and meta-analysis, we evaluated the efficacy of faricimab for PCV.

Characteristics of submacular hemorrhage with bacillary layer detachment and intrabacillary hemorrhage.

Purpose: To study the outcomes of patients presenting with submacular hemorrhage (SMH) and bacillary layer detachment (BALAD) following intervention.

Caffeine and Vision: Effects on the Eye.

Caffeine, commonly found in coffee and tea, affects various aspects of eye health as it blocks adenosine receptors, impacting tear production, intraocular pressure, macular perfusion, and choroidal thickness. However, its connection with eye conditions like glaucoma and cataracts remains uncertain due to conflicting research findings. Some studies suggest potential benefits for cataracts, while others warn against frequent caffeine intake in glaucoma and surgical scenarios due to possible increases in intraocular pressure.

The age-related macular degeneration (AMD) field is witnessing promising advancements in therapeutic options. Breakthrough drugs such as pegcetacoplan and avacincaptad have been FDA-approved for dry AMD, marking a significant development as there were no treatment options until August 2023. While several antivascular endothelial growth factor (VEGF) inhibitors have been approved for wet AMD, challenges persist with the need for frequent dosing.
