Wills Eye Hospital Papers

Retinopathy of prematurity (ROP) remains the leading cause of childhood blindness worldwide. Recent advances in ROP imaging have significantly improved our understanding of the pathogenesis and pathophysiological course of ROP including the acute phase, regression, reactivation, and late complications, known as adult ROP. Recent progress includes various contact and noncontact wide-field imaging devices for fundus imaging, smartphone-based fundus photography, wide-field fluorescein angiography, handheld optical coherence tomography (OCT) devices for wide-field en face OCT images, and OCT angiography. Images taken by those devices were incorporated in the recently updated guidelines of ROP, the International Classification of Retinopathy of Prematurity, Third Edition …

Quantitative Analysis Of Research On Artificial Intelligence In Retinopathy Of Prematurity, Ranjana Agrawal, Manasi Anup Agrawal, Sucheta Kulkarni, Ketan Kotecha, Rahee Walambe

Library Philosophy and Practice (e-journal)

Retinopathy of Prematurity (ROP) is a disease of the eye and a potential source of blindness in low birth weight preterm infants. It is preventable if diagnosed and treated on time. Artificial Intelligence (AI) has played an important role in developing automated screening systems to assist medical experts. There are many traditional literature review articles available that focus on the scientific content of ROP-AI. The researchers also require a bibliometric analysis to become acquainted with the competing groups and new trends in this field. This paper gives a brief overview of ROP and AI systems for ROP screening with a …

Adverse Events Following Screening Eye Examinations For Retinopathy Of Prematurity In Premature Infants, Aditi Kale, Pedro Urday, Zubair H. Aghai

Phase 1

Introduction: The retinopathy of prematurity (ROP) examination is recommended for high-risk preterm infants to prevent its complications but may be associated with adverse events. The goal of this study is to determine whether the ROP examination increases the incidence of adverse events in premature infants.

Design/Methods: This was a retrospective study on all preterm infants (32 weeks gestation) born between 03/2017 and 12/2019 who survived until the first eye examination. The number of episodes of apnea (A), bradycardia (B), desaturation (D), number of infants on mechanical ventilation, and number of infants requiring sepsis evaluation were compared before and …

BACKGROUND: Infants born very preterm are more likely to experience neonatal morbidities compared to their term peers. Variations in DNA methylation (DNAm) associated with these morbidities may yield novel information about the processes impacted by these morbidities.

METHODS: This study included 532 infants born < 30 weeks gestation, participating in the Neonatal Neurobehavior and Outcomes in Very Preterm Infants study. We used a neonatal morbidity risk score, which was an additive index of the number of morbidities experienced during the NICU stay, including bronchopulmonary dysplasia (BPD), severe brain injury, serious neonatal infections, and severe retinopathy of prematurity. DNA was collected from buccal cells at discharge from the NICU, and DNAm was measured using the Illumina MethylationEPIC. We tested for differential methylation in association with the neonatal morbidity risk score then tested for differentially methylated regions (DMRs) and overrepresentation of biological pathways.

RESULTS: We identified ten differentially methylated CpGs (α Bonferroni-adjusted for 706,278 tests) that were associated with increasing neonatal morbidity risk scores at three intergenic regions and at HPS4, SRRD, FGFR1OP, TNS3, TMEM266, LRRC3B, ZNF780A, and TENM2. These mostly followed dose-response patterns, for 8 CpGs increasing DNAm associated with increased numbers of morbidities, while for 2 CpGs …

Evidence To Date: Ranibizumab And Its Potential In The Treatment Of Retinopathy Of Prematurity, Samir Patel, Michael A. Klufas

Wills Eye Hospital Papers

Retinopathy of prematurity (ROP) is a leading and preventable cause of childhood blindness worldwide. Although laser photocoagulation remains the gold standard for treatment, the off-label use of anti-vascular endothelial growth factor (anti-VEGF) therapy to treat ROP, particularly posterior zone I disease, is increasing. Although initial studies on anti-VEGF therapy for ROP have focused on bevacizumab, recent studies have proposed that ranibizumab may be a safer and more effective alternative for use in this population. This review updates recent evidence regarding the use of ranibizumab in the management of ROP.

Turkish Journal of Medical Sciences

Retinopathy of prematurity (ROP) is one of the most frequent causes of blindness in newborn babies. Currently, its etiology is not fully understood. In this study we aimed to investigate the correlation between a patient group with ROP and a control group in terms of the tumor necrosis factor-alpha (TNF-alpha) (G308A) gene and glutathione-S-transferase P1 (GSTP1) (Ile105Val) gene polymorphism. Materials and methods: Sixty-two patients diagnosed with ROP and 58 control subjects were included in this study. For TNF-alpha (G308A) gene and GSTP1 (Ile105Val) gene polymorphisms, the polymerase chain reaction-restriction fragment length polymorphism method was used. In statistical analysis the significance …

Restricted Universal Guidelines For Rop Screening: A Possible Misguidance For Middle Income Countries, Ömer Erdeve, Begüm Atasay, Saadet Arsan, Fi̇gen Batuoğlu, Huban Ati̇lla, Tomri̇s Türmen

Turkish Journal of Medical Sciences

The objective of all studies evaluating retinopathy of prematurity (ROP) screening criteria has been to minimize the number of infants screened while missing no patients with ROP who required treatment. Studies supporting the recommendation that screening for ROP could be restricted to infants born at less than 30 weeks of gestation with birth weights of less than 1250 g have been reported recently, especially from Western countries. However, with the lack of local outcome data, application of the new restricted screening guidelines to infants in middle income countries may lead to misguidance. We aimed to investigate ROP screening requirements in …
