Retinopathy of prematurity (ROP) is a vasoproliferative disease of the preterm retina that has the potential to cause vision impairment and blindness. Timely screening and treatment are hence critical for infants at risk for ROP. Screening for ROP is challenging in India owing to the limited resources, a vast at-risk population and lack of awareness among paediatricians and the public. Addressing ROP in India requires a comprehensive approach involving multiple sectors, considering the magnitude of the problem and the expected increase in need for ROP services due to the increased survival of preterm infants following improvements in neonatal care. The success of the Global Polio Eradication Initiative (GPEI) offers valuable lessons for improving ROP services in developing nations by applying its strategies. An approach for primary and secondary prevention of ROP is proposed, and the current challenges and a neonatal-led care model for ROP are discussed.

Objective: To evaluate the incidence of thin catheter surfactant administration (TCA) failure and compare short and long-term neonatal outcomes who failed TCA or did not.

Design: Single-center retrospective cohort study. Infants between 25 and 30 weeks of gestational age with respiratory distress syndrome and receiving 200 mg/kg poractant alfa via thin catheter administration were included.

Retinopathy of prematurity (ROP) is a proliferative retinal vascular disorder that critically affects the visual development of premature infants, potentially leading to irreversible vision loss or even blindness. Despite its significance, the underlying mechanisms of this disease remain insufficiently understood. In this study, we utilized the oxygen-induced retinopathy (OIR) mouse model and conducted endothelial functional assays to explore the role of Sterol Regulatory Element-Binding Protein 1 (SREBF1) in ROP pathogenesis.

Background: Very premature infants screened for retinopathy of prematurity (ROP) that do not develop ROP still experience serious visual developmental challenges, and while it is recommended that all children in the UK are offered preschool visual screening, we aimed to explore whether this vulnerable group requires dedicated follow-up.

Methods: We performed a real-world retrospective observational cohort study of children previously screened for ROP in NHS Greater Glasgow and Clyde (Scotland) between 2013 and 2015. We excluded those with any severity of ROP identified during screening.

Purpose: To assess the utility of the first or second examinations for retinopathy of prematurity (ROP) in a medium-risk cohort of infants and to propose an optimization to the current ROP screening guidelines.

Design: Retrospective consecutive study.

Subjects: Infants screened for ROP between January 2017 and August 2023 at three different tertiary-level care neonatal intensive care units.

Systemic regulation of retinal medium-chain fatty acid oxidation repletes TCA cycle flux in oxygen-induced retinopathy.

Activation of anaplerosis takes away glutamine from the biosynthetic pathways to the energy-producing TCA cycle. Especially, induction of hyperoxia driven anaplerosis in neurovascular tissues such as the retina during early stages of development could deplete biosynthetic precursors from newly proliferating endothelial cells impeding physiological angiogenesis and leading to vasoobliteration. Using an oxygen-induced retinopathy (OIR) mouse model, we investigated the metabolic differences between OIR-resistant BALB/cByJ and OIR susceptible C57BL/6J strains at system levels to understand the molecular underpinnings that potentially contribute to hyperoxia-induced vascular abnormalities in the neural retina.
