Filter by:In premature infants, propranolol (Prop) treatment might suppress continuing neo-vascularization (NV) and decelerate the progression of retinopathy of prematurity (ROP) towards its severe stages (III-V), thus avoiding the need of interventions (CRYO and/or LASER photo-coagulation of the ischemic retina and preventing severe ocular sequelae. We therefore plan to prospectively investigate the influence of prop versus placebo in VLBW infants with ROP stage 1 (zone I), with stage 2 or higher (any zone) or with Plus disease, along with close follow up regarding safety of prop administration and its effect on ROP.
The purpose of this trial was to determine the efficacy and safety of supplemental therapeutic oxygen for infants with prethreshold retinopathy of prematurity (ROP) to reduce the probability of progression to threshold ROP and the need for peripheral retinal ablation.
The primary question to be addressed by this study is: compared with a functional oxygen saturation level (SpO2) of 91-95%, does targeting SpO2 85-89% in extremely preterm infants from birth or soon after, result in a difference in mortality or major disability in survivors by 2 years corrected age (defined as gestational age plus chronological age)?
To compare the severity of retinopathy of prematurity (ROP) among treated infants with an untreated control population, matched for gestational age at birth while confirming the dose of rhIGF-1/rhIGFBP-3 is safe and efficacious.
The purpose of this study is to determine whether the administration of propranolol is effective in the treatment of the retinopathy of the prematurity.
The purpose of this study is to compare the dilating effect of 0, 1, 2 or 3 drops of mydriatic (pupil dilating) in premature infants undergoing routine retinal (eye) screening exams for Retinopathy of Prematurity (ROP).
This pilot study is a randomized, placebo-controlled, clinical trial to measure changes in blood and urine levels of inositol in premature infants at high risk for retinopathy of prematurity (ROP) following repeated doses of inositol. Based on previous studies, the premise is that maintaining inositol concentrations similar to those occurring naturally in utero will reduce the rates of ROP and bronchopulmonary dysplasia in premature infants. The objective is to evaluate pharmacokinetics, safety, and clinical outcomes of multiple doses of three different dose amounts of myo-inositol (provided by Abbott Laboratories) in very low birth weight premature infants. This study will enroll an estimated 96 infants at 17 NICHD Neonatal Research Network sites. Infants will be randomly assigned to receive either 10 mg/kg of 5% inositol, 40 mg/kg of 5% inositol, 80 mg/kg of 5% inositol, or 5% glucose given in the same volumes and timings as the inositol dosage to maintain masking. Enrollees will receive their assigned dose or placebo daily, starting within 72 hours of birth, and continuing until they reach 34 weeks post-menstrual age, 10 weeks chronologic age, or until the time of hospital discharge, whichever occurs first. The study drug will be administered first intravenously; as the infants progress to full feeding, the drug will be given enterally (orally or via feeding tube). Enrollees will be seen for a follow-up examination at 18-22 months corrected age. This pilot study is in preparation for a future Phase III multi-center randomized controlled trial.
Retinopathy of Prematurity (ROP) screening is one of many potentially painful diagnostic and therapeutic procedures performed routinely on preterm infants in the Neonatal Intensive Care Unit. Therefore strategies for stress reduction and pain management are essential to promote growth and development and minimize long-term sequelae. Procedural analgesia should include concepts of developmental care, non nutritive suck (NNS), pharmacological and non-pharmacological agents. Sucrose is thought to stimulate the body's activation of lingual sweet taste receptors and release of endogenous opioids, when combined with NNS, non-opioid mechanisms are also activated. The administration of sucrose or the combination of sucrose and non-nutritive sucking is one of the most frequently studied non-pharmacological interventions for relief of pain in neonates and oral sucrose has been shown to be an effective and safe therapy for common neonatal procedures such as heal lance, blood-letting and venepuncture. There is conflicting evidence on the benefit of sucrose in ROP screening. Therefore the purpose of this study is to determine the efficacy of sucrose combined with NNS as a potential regime for reduction of pain associated with retinopathy of prematurity screening.
Retinopathy of prematurity screening is painful. Wide field digital retinal imaging (WFDRI) and binocular indirect ophthalmoscopy (BIO) are being used for screening examinations. The aim of Edinburgh, UK based study is to compare the pain experienced by infants using both examination techniques.
The primary objectives of this study are to compare the serum and skin concentrations of beta-carotene, lutein, and lycopene in preterm infants fed preterm formulas with mixed carotenoids to serum concentrations in preterm infants fed preterm formulas with no added carotenoids and to human milk fed infants. The secondary objective of this study is to evaluate the effects of dietary carotenoids on the developing eye. Stages and zones of retinopathy of prematurity (ROP), retinal function, and retinal characteristics will also be examined.
