Retinopathy of prematurity (ROP) continues to be an important cause of potentially preventable blindness worldwide. The pattern of visual impairment from ROP in some middle-income countries--high rates affecting larger and more mature infants--resembles that seen in more developed countries two decades ago and has been called a "third epidemic" of the disease. Expert bodies in the United Kingdom and the United States have recently issued new guidelines for screening for ROP that utilize both birth weight and gestational age criteria. Studies in both countries suggest these criteria might be further revised to decrease time spent on screening without missing any significant disease. Population-based follow-up studies of extremely preterm infants suggest that although more preterm infants are surviving, with adequate screening and treatment, rates of blindness from ROP may be declining. Further information on the longer-term impact of ROP comes from a number of studies and particularly the Multicenter Trial of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) study. The risk of both myopia and strabismus is increased with any and each higher stage of ROP. Evidence is emerging that laser therapy for threshold disease may be associated with better visual outcome than cryotherapy, although complications following the former remain a concern. The fight against ROP may be enhanced by new information on the pathogenesis, including possible genetic predisposition and the role of vascular endothelial growth factor.

Importance: Intraventricular hemorrhage (IVH) has proven to be a challenging and enduring complication of prematurity. However, its association with neurodevelopment across the spectrum of IVH severity, independent of prematurity, and in the context of contemporary care remains uncertain.
Objective: To evaluate national trends in IVH diagnosis and the association with survival and neurodevelopmental outcomes at 2 years of age.
Unlabelled: Hemodynamically significant patent ductus arteriosus (hs-PDA) in very low birth weight (VLBW) infants continues to be an issue of research regarding the timing of treatment and which would be the most appropriate drug.
Objective: To assess the outcome of prolonged treatment with paracetamol in the closure of hemodynamically significant patent ductus arteriosus in preterm newborns.
Patients And Method: Retrospective study in VLBW infants with echocardiographic and clinical diagnosis of hs-PDA who received treatment with intravenous paracetamol at 15 mg/kg every 6 hours for 6 days.

Unlabelled: Observational studies have described an increase in the duration of oxygen therapy, bronchopulmonary dysplasia (BPD), and retinopathy of prematurity (ROP) in relation to the use of high-flow nasal cannula (HFNC, 2013-2016).
Objective: to analyze changes in the evolution of very preterm newborns with the use of HFNC.
Patients And Method: The incidence of neonatal pathologies between 2013 and 2021 was analyzed with a statistical process control.

Retinal pathological angiogenesis (PA) is a common hallmark in proliferative retinopathies, including age-related macular degeneration (AMD), proliferative diabetic retinopathy (PDR), and retinopathy of prematurity (ROP). The mechanisms underlying PA is complex and incompletely understood. In this study, we investigated the role of extracellular matrix (ECM) protein biglycan (BGN) in PA using an oxygen-induced retinopathy (OIR) mouse model, along with hypoxia (1% O) conditions for incubating pericytes and endothelial cells in vitro.

Background: To analyze the demographic characteristics of retinopathy of prematurity (ROP) in China, attempting to propose optimized screening criteria and hopefully providing valuable information for future updates to the ROP guideline.
Methods: A multicenter, retrospective-cohort study was conducted. The study included infants born between January 1, 2018, and July 31, 2023, who underwent ROP screening and were diagnosed with ROP at seven screening centers in China.
