[¹⁷⁷Lu]Lu-PSMA-617 in patients with PSMA-positive metastatic androgen pathway modulator-naive/sensitive prostate cancer (PSMAddition): a phase 3 randomised, controlled trial

The PSMAddition trial aimed to evaluate the efficacy and safety of combining [^177Lu]Lu-PSMA-617 with androgen deprivation therapy (ADT) and androgen receptor pathway inhibitors (ARPI) in patients with PSMA-positive metastatic androgen pathway modulator-naive/sensitive prostate cancer. The results indicated that this combination significantly improved radiographic progression-free survival compared to the control group, despite a higher incidence of adverse events, suggesting it may be a viable new treatment option for this patient population.

No-History IOL Power Calculation After Myopic Laser Vision Correction: A Multicenter Retrospective Database Study of 14 Formulas With and Without Posterior Corneal Curvature

The authors aimed to evaluate the accuracy of various intraocular lens (IOL) power calculation formulas in eyes that had previously undergone myopic laser vision correction (M-LVC). Their findings indicate that modern formulas, particularly those incorporating posterior corneal curvature (PCC), significantly outperform early-generation formulas, with K6 and EVO 2.0 showing the best accuracy, especially in extreme corneal shapes and shorter axial lengths. The study suggests that while modern formulas provide improved outcomes, the clinical significance may be minimal in typical post-M-LVC cases.

Syncope

This article by Rose Anne Kenny addresses the clinical problem of syncope, which is characterized by transient cerebral hypoperfusion and can arise from various mechanisms such as reflex, orthostatic, and cardiac causes. The authors emphasize the importance of accurate diagnosis through thorough history taking, physical examination, and risk stratification to guide targeted testing and management strategies aimed at reducing recurrence and injury risk, particularly in older patients where syncope may present as unexplained falls. The study highlights the necessity of early identification of high-risk features to prevent adverse cardiovascular outcomes.

Neighborhood Socioeconomic Deprivation and Adherence to Diabetic Retinopathy Screening Guidelines

The authors aimed to investigate the relationship between neighborhood socioeconomic deprivation, as measured by the Area Deprivation Index (ADI), and adherence to diabetic retinopathy screening guidelines among Medicare beneficiaries. Their findings revealed that higher ADI scores were associated with significantly lower rates of adherence to annual screening, indicating that patients in more deprived neighborhoods are at a greater risk of nonadherence. This study highlights the importance of addressing socioeconomic factors to improve screening outcomes for diabetic retinopathy.

Factors associated with delays in the diagnosis of childhood onset uveitis: findings from a nation-wide cohort study

The authors aimed to identify factors associated with delays in the diagnosis of childhood onset uveitis. Their study found that the median time from symptom onset to diagnosis was 9 days, with bilateral disease and initial presentation to primary care being significant predictors of increased delay. Additionally, younger age and socioeconomic deprivation were linked to a higher likelihood of structural complications at diagnosis, highlighting the need for improved awareness and referral pathways in primary care.

In Vivo Microscopic Assessment of Ocular Surface Changes Induced by Antiglaucoma Medications

The authors aimed to investigate the effects of topical antiglaucoma medications on ocular surface disease (OSD) in patients with glaucoma using in vivo confocal microscopy. Their findings indicate that chronic use of these medications significantly worsens OSD symptoms and leads to microstructural changes in the cornea, with beta-blockers causing more damage than prostaglandin analogs. The study highlights the need for clinicians to consider the adverse effects of antiglaucoma treatments on the ocular surface.

Optical coherence tomography-guided focal navigated laser photocoagulation in central serous chorioretinopathy: a non-inferiority study

The authors aimed to evaluate the efficacy and safety of en face optical coherence tomography (OCT)-guided navigated focal laser photocoagulation compared to fluorescein angiography (FA)-guided treatment for central serous chorioretinopathy (CSCR). The study found that OCT-guided treatment achieved a similar rate of complete resolution of subretinal fluid and demonstrated non-inferior safety and efficacy compared to the conventional FA-guided approach, with no adverse events reported in either group.

Central Retinal Vessel Trunk Dragging in Highly Myopic Eyes

The authors aimed to investigate the prevalence and associations of central retinal vessel trunk (CRVT) dragging in highly myopic eyes. They found that CRVT dragging is common in these eyes, with its prevalence significantly increasing with longer axial lengths and greater optic disc-fovea distances, suggesting a relationship between myopic axial elongation and the morphological changes observed in the optic nerve head. The study highlights the potential importance of CRVT dragging in diagnosing optic neuropathies in highly myopic patients.

Refining How We Diagnose and Classify Limbal Stem Cell deficiency

The authors aim to refine the diagnosis and classification of limbal stem cell deficiency (LSCD) by establishing a comprehensive algorithm that incorporates multimodal imaging and molecular diagnostic tests. They highlight the limitations of traditional methods, such as fluorescein staining, and advocate for a standardized approach that considers various ocular surface factors and comorbidities to enhance diagnostic accuracy and guide treatment strategies. Ultimately, this framework seeks to improve the management of LSCD and facilitate the development of new regenerative therapies.

Glaucoma and Neurodegenerative Disease Risk: A 10-Year Assessment of Real-World Global Data

The authors aimed to assess the 10-year risk trajectories of newly diagnosed neurodegenerative diseases among glaucoma patients, analyzing data across age-stratified cohorts and clinical subtypes. Their findings indicate that glaucoma is associated with increased risks for Alzheimer's disease, vascular dementia, and mild cognitive impairment, with variations in risk based on the age of onset and specific glaucoma subtype. However, the study highlights that these associations are observational and do not establish causal relationships.
