Article Synopsis
  • This study aims to examine the histopathology and outcomes in patients with retinoblastoma who underwent eye enucleation and had neovascular glaucoma (NVG).
  • The research included 1,420 total cases from five continents, revealing that 16% of patients with NVG were often at higher risk of severe histopathological findings.
  • The findings indicate that NVG is linked to more aggressive forms of the disease and a higher chance of metastasis, emphasizing the need for careful monitoring and treatment in these cases.

Purpose: This study compared two imaging grading techniques to assess the utility of longitudinal image-based analysis in retinopathy of prematurity (ROP) screening: (1) time-limited without image comparison (a proxy for bedside indirect ophthalmoscopy, termed sBIO) and time-unlimited with image comparison (for telemedicine grading, termed TELE) screening. We tested two hypotheses: (1) H1: TELE was superior to sBIO for the detection of change (Tempo)-same, better, or worse and (2) H2: granular data of change (e.g.

MYCN-amplified RB1 wild-type (MYCNRB1) retinoblastoma is a rare and aggressive subtype, often resistant to standard therapies. Identifying unique MRI features is crucial for diagnosing this subtype, as biopsy is not recommended. This study aimed to differentiate MYCNRB1 from the most prevalent RB1 retinoblastoma using pretreatment MRI and radiomics.

Purpose: To compare the clinical outcomes of children with unilateral retinoblastoma (Rb) and high-risk histopathology features (HRHF) following upfront enucleation with/without adjuvant chemotherapy, and investigate cases locally considered non-HRHF but converted to a standardized HRHF definition.

Design: Retrospective multinational clinical cohort study.

Methods: Children with Rb who presented to 21 centers from 12 countries between 2011-2020, and underwent primary enucleation were recruited.

Article Synopsis
  • The study aimed to analyze high-risk histopathological features in eyes with retinoblastoma (RB) after enucleation and compare patient outcomes globally.
  • A total of 1,426 RB cases were reviewed, revealing significant differences in histopathological features across continents, with Asia showing the highest rates of massive choroidal invasion and optic nerve invasion.
  • The findings indicated that patients from South America and Asia faced greater risks of tumor recurrence, systemic metastasis, and mortality compared to those from Australia, Europe, and North America.

Design: Multireader diagnostic accuracy imaging study.

Participants: Eleven ROP experts, 9 of whom had been in practice for 10 years or more.

Introduction: The objective of this study was to report the clinicopathologic features of three cases of -amplified retinoblastoma identified genetically by aqueous humor sampling.

Methods: Whole-genome sequencing was performed using isolated cell-free DNA (cfDNA) from aqueous humor of 3 retinoblastoma patients. We analyzed genomic copy number and mutational alterations, histologic and pathologic features, and clinical data.

Purpose: To explore characteristic imaging features of nonparaneoplastic autoimmune retinopathy (npAIR) to augment diagnostic criteria.

Methods: This is a retrospective cohort study of patients with npAIR evaluated at the Emory Eye Center between 2013 and 2019. Multimodal fundus images were evaluated to characterize the evolution of the disease.

Objectives: To validate associations between MRI features and gene expression profiles in retinoblastoma, thereby evaluating the repeatability of radiogenomics in retinoblastoma.

Methods: In this retrospective multicenter cohort study, retinoblastoma patients with gene expression data and MRI were included. MRI features (scored blinded for clinical data) and matched genome-wide gene expression data were used to perform radiogenomic analysis.

Purpose: To report a case of severe retinal ischemia in an infant with neurofibromatosis type 1.

Methods: Chart review, analysis of imaging studies, and review of literature.

Results: A boy born at 37 weeks postmenstrual age with neurofibromatosis type 1 was noted to have a large plexiform neurofibroma with left-sided involvement of the cavernous sinus, internal carotid artery, orbit, and optic nerve.

Background -amplified wild-type () retinoblastoma is a rare but clinically important subtype of retinoblastoma due to its aggressive character and relative resistance to typical therapeutic approaches. Because biopsy is not indicated in retinoblastoma, specific MRI features might be valuable to identify children with this genetic subtype. Purpose To define the MRI phenotype of retinoblastoma and evaluate the ability of qualitative MRI features to help identify this specific genetic subtype.

Purpose: Retinoblastoma (RB) is most often diagnosed with clinical features and not diagnosed with tumor biopsy. This study describes tumor-derived analyte concentrations from aqueous humor (AH) liquid biopsy and its use in clinical assays.

  • - The study reports on 6 cases of diffuse choroidal hemangioma in children treated with iodine-125 plaque brachytherapy at a specialized medical center.
  • - All patients initially had poor vision and significant retinal detachment, but after treatment, there was tumor regression and improvement in vision for some, with a follow-up showing no major complications like neovascular glaucoma.
  • - While iodine-125 brachytherapy proved effective in reducing tumors, some patients experienced radiation-related side effects, highlighting a need for careful monitoring.

Laser is effective at treating exudative retinal detachment (ERD) in Coats' disease. However, with severe ERD, the retina may be in contact with the lens. In such cases, laser can result in cataract formation.

Purpose: To investigate late vitreoretinal complications and visual outcomes in patients with regressed retinopathy of prematurity (ROP) with or without prior treatment.

Design: International, multicenter, noncomparative retrospective case series.

Participants: We analyzed 264 eyes of 238 patients from 13 centers worldwide who developed vitreoretinal complications (retinal detachment [RD], vitreous hemorrhage [VH], or retinal break) ≥ 2 years after resolution of acute ROP.

Purpose: To evaluate the prevalence of retinal disease on fluorescein angiography (FA) in patients with incontinentia pigmenti (IP) and to compare the severity of retinal disease in those with and without known central nervous system (CNS) disease.

Design: Multi-institutional consecutive retrospective case series.

Subjects: New patients with a diagnosis of IP were seen at the Casey Eye Institute at the Oregon Health and Science University (OHSU), Moran Eye Center, University of Utah, or Bascom Palmer Eye Institute, University of Miami from December 2011 to September 2018.

The authors describe a challenging case of unilateral retinoblastoma in a patient referred for xanthocoria. A 3-year-old boy was referred for unilateral xanthocoria and disordered retinal vasculature, suggestive of Coats disease. Further investigation revealed diffuse subretinal tumor seeding and areas of calcification, consistent with retinoblastoma.

Background: Application of current retinopathy of prematurity (ROP) screening criteria results in many unnecessary examinations, because only 5%-10% of infants screened require treatment. Application of screening criteria established by the Postnatal Growth and Retinopathy of Prematurity Study could significantly reduce unnecessary examinations without sacrificing sensitivity to detect treatment-requiring ROP. We evaluated the performance of the G-ROP criteria in a population of high-risk, outborn infants.

A male infant born at 23 weeks gestation with a birthweight of 660 grams presented with retinopathy of prematurity (ROP) that began progressing at 44 weeks. He subsequently developed Zone III, Stage 3, pre-plus disease in both eyes (OU), as well as scattered exudates in the macula, dragged vessels temporally, and an exudative retinal detachment temporally in the left eye after a period of regressing and stable ROP. After bilateral laser photocoagulation, there was regression of the neovascularization, resolution of the exudative detachment, and eventual stabilization of disease OU by 12 months postmenstrual age.
