Diabetic retinopathy (DR) is one of the leading causes of vision loss among people of working age. However, people with diabetes are often unaware of the importance of DR screening for preserving vision, highlighting the importance of patient education about DR and DR-related ocular and systemic comorbidities. In this podcast, three patients with different stages of DR and two ophthalmologists exchanged their views on diagnosis, treatment, and progression of DR and diabetic macular edema.

Design: Post hoc analysis of PANORAMA.
Participants: Patients with moderately severe to severe NPDR enrolled in the prospective PANORAMA phase 3 trial.
Age-related macular degeneration (AMD), a complex neurodegenerative disease, is a leading cause of visual impairment worldwide with a strong genetic component. Genetic studies have identified several loci, but few causal genes with functional characterization. Here we highlight multiple lines of evidence which show a causal role in AMD for SLC16A8, which encodes MCT3, a retinal pigment epithelium (RPE) specific lactate transporter.

Design: Retrospective, observational, multicenter study.
Participants: Patients with idiopathic FTMH presenting to St.
Purpose: To evaluate the safety and tolerability of a single dose of axitinib injectable suspension (CLS-AX), a pan-anti-VEGF tyrosine kinase inhibitor (TKI), administered via suprachoroidal injection in patients with neovascular age-related macular degeneration (nAMD).
Design: Phase I/IIa, open-label, sequential dose escalation.
Participants: Anti-VEGF treatment-experienced patients with active subfoveal choroidal neovascularization secondary to nAMD.
To review sustained-release intraocular platforms used to treat diseases of the retina and choroid. A literature review of the current applications of biomaterials for sustained-release therapy in retinal and choroidal diseases was performed. Retinal and choroidal diseases, such as neovascular age-related macular degeneration (nAMD), diabetic retinopathy (DR), diabetic macular edema (DME), and uveitis, are commonly treated using intravitreal (IVT) therapies that require frequent IVT injections.

Design: Multicenter, randomized, double-masked phase 3a study.
Participants: Participants with recalcitrant nAMD (persistent residual retinal fluid despite previous frequent anti-VEGF treatment).
To report a case of a suspected open-globe injury and globe penetration complicated by a rhegmatogenous retinal detachment (RRD) after administration of intraoral anesthetic injections during an endodontic procedure. A retrospective chart review was performed. A 34-year-old woman presented with acute onset of flashes, floaters, and a curtain-like shadow across her field of vision.

A synthesis of the literature was performed. In 2021, suprachoroidal space triamcinolone acetonide, a corticosteroid delivery system used for the treatment of uveitic macular edema (ME), was approved by the US Food and Drug Administration.

Design: a retrospective observational study.
Participants: 54 treatment-naïve eyes (27 DR and 27 AMD).
Introduction: This study reports our experiences with systematic retinal screening in Denmark through optometrists with access to tele-ophthalmological services before, during, and after the COVID-19 pandemic.
Methods: We evaluated an optometrist-based retinal screening system with a referral option for tele-ophthalmological service by a consultant ophthalmologist within the time period of August 1, 2018 to September 30, 2023. The optometrist collected patient history, refraction, best-corrected visual acuity, intraocular pressure, basic slit-lamp examination, 4-in-1 visual field report, and retinal imaging using color fundus 45° photography.
Purpose: This study was designed to investigate retinal nerve fiber layer circumpapillary optical coherence tomography to determine posterior vitreous detachment (PVD) status and to develop a clinically relevant PVD grading scale based on retinal nerve fiber layer circumpapillary optical coherence tomography to determine the incidence of PVD by age and association with vitreomacular traction disorders.
Methods: Ophthalmic images and medical records of patients with retinal diseases were retrospectively analyzed by three masked graders using retinal nerve fiber layer circumpapillary optical coherence tomography and macular optical coherence tomography. Based on PVD status, eyes were categorized into five newly defined PVD stages.
Objective: To assess the effect of the COVID-19 pandemic on injection intervals among patients treated for neovascular age-related macular degeneration.
Design: Retrospective cohort study.
Participants: Patients treated at a single practice using a treat-and-extend regimen with intravitreal aflibercept between December 2018 and April 2021.
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.

Updating the DRD staging system to incorporate relevant basic and cellular mechanisms pertinent to DRD is necessary to better address early disease, disease progression, the use of therapeutic interventions, and treatment effectiveness.
Design: We sought to review preclinical and clinical evidence on basic and cellular mechanisms potentially pertinent to DRD that might eventually be relevant to update the DRD staging system.
Importance: Anti-vascular endothelial growth factor (VEGF) intravitreal injections, a mainstay of treatment for many retinal diseases to optimize visual outcomes, have been included in prior authorization (PA) initiatives. However, if clinicians are extremely accurate in their use of anti-VEGF medications, such administrative burdens may need reconsideration.
Objective: To quantify PA for anti-VEGF medications (aflibercept, ranibizumab, and bevacizumab) that were approved and determine associated administrative burdens experienced by retina practices.
