It occurs when the baby's retina, the part of the eye that senses light, does not develop normally. This may result in vision problems, including blindness, if left untreated. Preterm babies are born before 37 weeks of pregnancy. ROP is more likely to develop in babies who are born before 32 weeks of pregnancy or weigh less than 1.5 kilograms at birth.Aflibercept is a drug that is injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth of blood vessels in the retina.Aflibercept in PFS given using a PDD is approved for the treatment of babies with ROP. The prefilled syringe will be fitted with an injection needle to give aflibercept. And a PDD is a tool used to give the right amount of aflibercept to children in a safe manner.Since there are other treatments which are commonly used for babies with ROP, the extent of use of aflibercept given using a PDD is unknown.The main purpose of this study is to:* find the number of preterm babies who are treated with aflibercept using a PDD in the UK* inform whether this number is enough to perform a study to learn about the long-term safety of aflibercept given using a PDD in babies with ROPAn additional purpose of this study is to describe characteristics including age, sex, and race, and signs and symptoms of ROP observed in babies being treated with aflibercept using a PDD.The data will come from a database called the National Neonatal Research Database. The study will cover the period from March 2024 to March 2025, if the number of babies found is enough to perform the safety study. If not, data will be collected till April 2027.In this study only available data from preterm babies born during the study period are collected. No visits or tests are required as part of this study., conditionsModule conditions: Retinopathy of Prematurity, conditions: Preterm Infants, designModule studyType: OBSERVATIONAL, designInfo observationalModel: COHORT, timePerspective: CROSS_SECTIONAL, enrollmentInfo count: 200, type: ESTIMATED, armsInterventionsModule interventions name: Aflibercept (Eylea), outcomesModule primaryOutcomes measure: Number of participants treated with Eylea PFS+PDD upon completion of 1- or 3-years following market introduction, secondaryOutcomes measure: Summary of patient characteristics reported as number of participants with different categories, secondaryOutcomes measure: Summary of maternal factors reported as number of participants with different categories, secondaryOutcomes measure: Summary of comorbidities reported as number of participants with different categories, secondaryOutcomes measure: Summary of clinical condition and resource utilization reported as number of participants with different categories, secondaryOutcomes measure: Summary of clinical condition and resource utilization reported as days, secondaryOutcomes measure: Summary of outcomes of the premature infants reported as number of participants with different categories, secondaryOutcomes measure: Summary of ocular disease and treatment reported as number of participants with different categories, eligibilityModule sex: ALL, maximumAge: 1 Year, stdAges: CHILD, contactsLocationsModule locations facility: Many locations, status: RECRUITING, city: Multiple Locations, country: United Kingdom, hasResults: False
