Retinopathy of Prematurity (ROP)

The purpose of this study is to evaluate safety and efficacy outcomes following exposure to FLQ-101.

Retinopathy of prematurity (ROP) is a disorder of development of the retina and its vasculature that can impact vision in vulnerable preterm neonates for a lifetime. A major barrier to improving ROP outcomes is the lack of easy access and low stress means to obtain objective measures of ROP disease severity across the retina in these infants. The long-term goal of this program is to provide information which will improve preterm infant health and vision via objective bedside imaging and analysis that characterizes retina-wide ROP level of disease, its response to treatment and development, and to rapidly translate this for better early intervention and improved future vision care.

The goal of this proposal is to develop novel HH-SECTR technology for visualizing and quantifying diagnostic disease features in prematurely born infant retinopathy of prematurity (ROP) patients that lead to more informed clinical decision making. Providing depth-resolved vascular information has not been adequately investigated for its diagnostic potential. Furthermore, we seek to identify disease features not currently accessible by standard examination methods to better inform clinical decisions.

Evaluating the Optimal Effective Dose and Safety of Conbercept in Treating Retinopathy of Prematurity (ROP)

The goal of this clinical trial is to learn whether intranasal fentanyl (a pain medicine given as a nasal spray) can reduce pain and is safe to use during routine eye examinations for retinopathy of prematurity (ROP) in preterm infants. ROP is an eye condition that can affect babies born too early and requires regular eye examinations. The main questions this study aims to answer are: Does intranasal fentanyl lower pain during ROP screening? Is intranasal fentanyl safe for preterm infants? Researchers will compare intranasal fentanyl with a placebo (a saltwater spray that contains no medicine) to determine whether the medicine lowers pain during ROP screening. Participants will receive either intranasal fentanyl or placebo before their routine ROP eye examination, in addition to the standard comfort measures normally used during the procedure. Researchers will measure participants' pain and monitor their heart rate, oxygen levels, and any side effects during and after the examination.

The goal of this clinical trial is to learn whether Health Belief Model (HBM)-based educational interventions can improve knowledge and practices related to Retinopathy of Prematurity (ROP) screening among parents of premature infants attending ROP clinics in Karachi, Pakistan. The main questions it aims to answer are: * Do HBM-based educational interventions improve parents' knowledge about Retinopathy of Prematurity screening? * Do HBM-based educational interventions improve parents' screening-related practices and follow-up for Retinopathy of Prematurity? Researchers will compare different educational approaches, including video-based education, audio-based education, and standard educational material, to see which method is more effective in improving parental understanding and practices regarding ROP screening. Participants will: * Complete a questionnaire assessing their knowledge and practices related to Retinopathy of Prematurity screening at baseline * Receive one of the following educational approaches: video message plus counselling and pamphlet, audio message plus counselling and pamphlet, or counselling and pamphlet only * Attend a follow-up visit approximately 2 weeks after the initial visit * Complete a follow-up questionnaire to assess changes in knowledge and practices related to Retinopathy of Prematurity screening

Anemia is a condition in which there are not enough red blood cells to carry oxygen throughout the body. It is very common in extremely preterm infants (born before 28 weeks of pregnancy), and many of these babies require red blood cell transfusions during their hospital stay. Currently, transfusions are given using red blood cells donated by adults. An alternative option is to use red blood cells collected from umbilical cord blood, which may be more similar to a newborn's own blood. This approach has been used in some neonatal units with encouraging results and no reported safety concerns. This study aims to determine whether transfusion with umbilical cord blood improves clinical outcomes and reduces potential side effects compared to standard adult donor blood transfusion in extremely preterm infants. We hypothesize that umbilical cord blood transfusion will be at least as safe as adult donor blood and may provide clinical benefits. About 115 extremely preterm infants admitted to neonatal units in Catalonia will participate. If parents agree, their baby will be randomly assigned to receive either compatible umbilical cord blood or compatible adult donor blood if a transfusion becomes necessary. Babies will only receive a transfusion if they clinically need one. If cord blood is not available at the time of transfusion, the baby will receive compatible adult donor blood regardless of the assigned group. To evaluate the response to treatment, small blood samples will be collected at birth, at one month of life, and 24 hours after any transfusion. These samples are taken at the same times as routine blood tests, so participation does not require additional needle sticks. The amount of blood collected is minimal (about 0.2 mL per sample). In addition, a painless and non-invasive sensor will be placed on the baby's head for 24 hours to measure oxygen delivery to the brain. Urine samples will also be collected before and after transfusion to help assess how oxygen reaches body tissues. Participation will continue until the baby reaches 36 weeks of postmenstrual age or is discharged from the hospital, whichever comes first.

Children born prematurely may develop a characteristic retinal disease named retinopathy of prematurity (ROP). This disease could lead to retinal detachment and blindness. ROP was traditionally treated with laser, but injection with a medication (A-VEGF) has become more common. In this study, the researchers will explore whether treatment of ROP affects visual function and retinal development. To explore this, the study group will examine children with ROP (but not treated) with children treated with either laser or injection. The researchers will compare the children's visual functions (e.g. visual acuity and visual field) and their retinas (e.g. central and peripheral retina).

The aim of this clinical trial is to learn if there is a correlation between the erythrocyte transfusion in the early neonatal period in premature infants and early and late complications of prematurity. The main questions it aims to answer are: * Do premature infants who receive blood transfusions within their first month of life have a higher risk of early prematurity complications, such as retinopathy of prematurity, necrotising enterocolitis, bronchopulmonary dysplasia, and intraventricular haemorrhage? * Do premature infants who receive blood transfusions during their first month of life have worse neurological and neurodevelopmental outcomes than those who do not? The first part of the study is retrospective, using data collected from participants' histories. The second part is prospective, evaluating neurological and neurodevelopmental outcomes at the age of six years.

The goal of this randomized controlled trial is to determine the effect of reverse kangaroo care position and ROP (Retinopathy of Prematurity) position applied during ROP examination in premature infants on pain. The main questions it aims to answer are as follows: 1. Is the reverse kangaroo care position effective in reducing the pain of premature infants during the ROP examination? 2. Is the reverse kangaroo care position more effective in reducing the pain of premature infants compared to the ROP position during the ROP examination? Researchers will determine the effect of reverse kangaroo care position and ROP position applied during premature retinopathy examination in premature infants with a gestational age of less than 34 weeks on pain in infants. * The infants of parents who volunteer to participate in the study will be divided into two groups as Reverse Kangaroo Care Position group and ROP Position group according to randomization. * From the infants whose pupils are sufficiently mydriasis and are taken to the examination table, premature infants in the ROP Position group will be given ROP position together with the nurse and the parent. * Premature infants in the Reverse Kangaroo Care Position group will be given reverse kangaroo care position. * Video recording will be made during the given positions. * The effects of the applied positions on pain will be determined as a result of the measured parameters before, during and after the examination.

There is limited knowledge on ophthalmological outcomes in the adult population that was born prematurely. This study aims to evaluate the ophthalmic outcomes of ex-premature infants that have reached adolescence or adulthood.
