View clinical trials related to Retinopathy of Prematurity.
Filter by:Currently, there is little recent data on regional variations in treatment methods, neonatal units that provide retinopathy (ROP) treatment, facilities for treatment available at each unit including anaesthetic support for such preterm babies, facilities to transfer babies to units that offer treatment etc. While some parts of the UK have established neonatal networks and agreements among units for ROP treatment, in other parts, such arrangements are illdefined. The number of babies needing ROP treatment may be higher since the introduction of revised guidelines in 2008 as earlier treatment has been shown to be beneficial. Collecting epidemiological data through the British Ophthalmic Surveillance Unit (BOSU) on the incidence of treatable ROP, the treatment methods used and facilities for treatment will provide the foundation for effective planning of resources and manpower to deal with the additional demand.
The purpose of this study is to find a dose of intravitreal bevacizumab that is lower than currently used for severe retinopathy of prematurity (ROP), is effective in this study, and can be tested in future larger studies.
The main purpose of this study is to evaluate the long-term efficacy and safety outcomes following short-term exposure to rhIGF-1/rhIGFBP-3 versus standard neonatal care in Study ROPP-2008-01 (NCT01096784).
The purpose of this study was to determine if intravitreal ranibizumab is superior to laser ablation therapy in the treatment of retinopathy of prematurity (ROP).
Phase 2, open-label, randomized, multi-center studies in infants and premature infants are necessary to determine treatment and preventative strategies for ROP. This study was designed to: a) target infants at the highest risk of ROP in a large number of centers with variable rates of ROP (all stages and severe ROP or stage 3+); and b) assess whether caffeine plus systemic or ophthalmic NSAID will decrease ROP among infants most at risk for ROP. The study is designed to determine whether the novel treatment regimens are safe and potentially effective for ROP prevention and to obtain requisite data for the development of a Phase III efficacy/safety randomized blinded trial. Since caffeine is used extensively in NICUs as standard of care for ELGANs, no placebo group is included.
Retinopathy of prematurity (ROP) is a neovascular retinal disorder of premature born children, characterized by the development of retinal neovascularisation, macular dragging and eventually retinal detachment. ROP is a leading cause for childhood blindness, especially in developing countries. Vascular endothelial growth factor (VEGF) plays an important role in the development of the disease. Recently, the BEAT ROP study tested the efficacy of intravitreal bevacizumab for stage 3 plus ROP in a prospective, controlled, randomized, stratified, multicenter trial. Authors found that bevacizumab showed a significant benefit for Zone I but not Zone II disease, with continuation of peripheral retinal vessel growths after treatment. The authors also concluded that safety could not be assessed due to the small sample size. Other authors raised concerns regarding the results of the BEAT ROP study and the safety of bevacizumab. The investigators suspected a better safety profile for ranibizumab to treat stage 3 plus ROP. Here we present the outcome of 6 eyes with ROP stage 3 plus treated with a single injection of ranibizumab.
The purpose of this study is to determine whether telemedicine would be as effective as having a pediatrics ophthalmologist on site for screening examination of retinopathy in premature infants and would be cost-effective.
This study is designed as an exploratory study to assess safety and efficacy of two different doses of the anti-VEGF agent ranibizumab (0.12 mg vs. 0.20 mg) in the treatment of infants with retinopathy of prematurity. Furthermore it shall help to improve safety in the treatment of ROP and provide explorative data on long-term effects of ranibizumab after intravitreal injection in neonates. The primary objective is to assess clinical efficacy of ranibizumab in children with ROP
Vitamin A is essential for optimal growth, and development. In the newborn, especially if preterm, it is necessary for the cellular differentiation, for the health of the anterior eye, it is a constituent of visual pigment, and it is essential for surfactant synthesis. Immune response Vitamin A supplementation demonstrated to reduces infancy mortality, but very low (<1500g birth weight) and extremely low (<1000g birth weight) preterm infants are born with low body stores of vitamin A and are at high risk of vitamin A deficiency. Nevertheless, optimal vitamin A supplementation for these infants is not clearly defined, despite evidence of benefit of an early supplementation. Prematurity is associate to the risk for bronchopulmonary dysplasia (BPD) which is a disease marked by respiratory compromise associated with high mortality and severe long-term morbidity, as well as prematurity is associate to the risk for retinopathy, a pathology that may be related to less rhodopsin quantity which seem dependent on vitamin A concentration. Vitamin A can be given enterally, intramuscularly, or intravenously. Recently an oral administration as drops is available resulting particularly convenient avoiding the pain associated with repetitive intramuscular injections, or the discomfort of parenteral administration. Studies of vitamin A in the infant population suggest that plasma retinol concentrations >0.7 µM/L indicate vitamin A sufficiency, nevertheless preterm infants have lower concentration and concentration < 0.35 µM/L are very dangerous. Vitamin A deficiency at this level may constitute a problem for preterm newborn, resulting for example, in histological alterations in the respiratory epithelium leading to chronic lung disease, retinopathy of prematurity, patency of the ductus arteriosis, and immune competence deficiency. The aim of the present study is to verify efficacy and tolerability of a new oral administration of vitamin A as drops, 3000 IU/kg/die for 4 weeks, in infants < 1500g weight at birth, verifying the competence of the supplementation reaching ideal blood concentration (≥0.7 µM/L) and relating the blood achieved concentrations of vitamin A to the outcome in typical pathologies, as BPD and ROP. Not treated group of matched newborn infants is the controlarm.
The aim of the present study is to evaluate the safety and efficacy of propranolol eye drops in preterm newborns with a precocious stage of retinopathy of prematurity (ROP). Preterm newborns (gestational age 23-32 weeks) with a stage 2 ROP (zone II without plus) will receive propranolol eye drops treatment until retinal vascularization will be completed. Propranolol concentrations will be measured on dried blood spots during the first 3 days of treatment and at the steady state. Cardiovascular and respiratory parameters will be continuously monitored. Blood samplings checking metabolic, renal and liver functions will be performed periodically, as well as cardiac function, in order to verify the treatment safety. Serial ophthalmological evaluations will be planned to monitor the efficacy of the treatment, the ROP progression and the possible complications.
