Active clinical trials for "Retinal Diseases"

Retinopathy of Prematurity (ROP); It is a disease of premature and low birth weight infants, characterized by incomplete vascularization of the retina, etiology and pathogenesis of which is unknown, and causes vision loss. There is an increase in the incidence and severity of ROP development in direct proportion to the decrease in birth week and birth weight. While ROP is a problem below 32 weeks of gestation in developed countries, it is reported to develop severely up to 34 weeks of gestation in developing countries. In a multicenter study conducted by the Turkish Neonatology Society in our country, the frequency of ROP in very low birth weight preterm infants was found to be 42%, and the frequency of advanced ROP was 11%. The incidence of ROP in babies with a gestational age of 33-35 weeks was 6.1%, and advanced ROP was 6 per thousand. The frequency of ROP was found to be 10.3% in babies with a birth weight of 1500-2000 grams, and severe ROP was reported in 19 of these babies. ROP examination is a procedure that causes pain, deterioration in comfort and physiological changes in preterm newborns. After this examination, an increase in blood pressure and heart rate and a decrease in oxygen saturation are observed. Pharmacological and non-pharmacological (non-pharmacological) methods are used to reduce the pain and increase the comfort level of the premature newborn. As a pharmacological method, there is no other routine method used to reduce pain other than the administration of local anesthetic drops before the examination. Because of this situation, nurses apply various non-pharmacological methods to alleviate pain. These methods are; breast milk, sucrose use, oral dextrose use, non-nutritive sucking, positioning, listening to music and mother's voice. In the literature, no specific study was found in which music was used to reduce pain and increase the comfort level during the ROP examination. Therefore, this research will be carried out to determine the effect of different music played on the pain and comfort level of premature babies during the retinopathy examination.

This study aimed to compare the effectiveness of two interventions, white noise, and multisensory stimulation, during retinopathy examinations on premature infants. Retinopathy is a common eye disorder among premature infants, which can cause visual impairments if not addressed. The research used a randomized controlled experimental design, with premature infants randomly assigned to either the white noise or multisensory stimulation group or control group. Physiological responses, behavioral indicators, and the pain of the retinopathy examination were measured. Trained healthcare professionals conducted the investigations in a controlled environment, and statistical analyses were employed to compare the outcomes between the three groups. The findings of this study have the potential to inform the development of more effective and well-tolerated examination protocols for premature infants, leading to improved visual outcomes and overall well-being for this vulnerable population.

Purpose: It was planned as a randomized controlled experiment in order to evaluate the effectiveness of the ocean sound on pain, comfort and physiological parameters in the NICU, Retinopathy of Prematurity (ROP) examination. Design: This is single-center. randomized controlled trial, double blind, parallel. Hypotheses: H0a: There is no difference between the pain levels (scale score) of premature babies in the control group and the ocean sound group. H0b: There is no difference between the comfort levels (scale score) of premature babies in the control group and the ocean sound group. H0c: There is no difference between the physiological parameters of the premature babies in the control group and the ocean sound group. H1a: There is a difference between the pain levels (scale score) of premature babies in the control group and the ocean sound group. H1b: There is a difference between the comfort levels (scale score) of premature babies in the control group and the ocean sound group. H1c: There is a difference between the physiological parameters of the premature babies in the control group and the ocean sound group. Method: The population of the research will be preterm babies who are treated at Necmettin Erbakan University Meram Medical Faculty NICU and will have their first ROP examination. Premature babies to be included in the study will be assigned to two study groups using the quadruple balanced block randomization method created in the computer environment according to their gestational age. In the study, the baby information form, Premature Baby Pain Profile Scale-Revised Form (PIPP-R), and Premature Baby Comfort Scale (PBIC) created by the researcher by scanning the literature will be used. Data will be collected by researcher GA. Infants who meet the criteria for inclusion in the study will be selected from the infants who are planned to undergo an ROP examination, and written and verbal consent will be obtained from the families by explaining the purpose of the study before the application. The information contained in the "Baby Information Form" will be obtained from the nurse observation form and patient files. On the day of the ROP examination, babies who meet the inclusion criteria before the procedure will be recorded outside the incubator with a video recorder in the room where the ROP examination will be performed (a room with 45-50 dB sound). Two minutes before the ROP, the baby will be monitored and physiological parameters will be recorded, and one minute before the ROP, the experimental group will start to listen to the ocean sound (Video recordings will be evaluated by two experts, PIPP-R and PBIC). After the necessary disinfection process is done, the voice recorder will be placed in the incubator at a distance of 20 cm from the baby's head and the sound level will be adjusted to an average of 55 decibels. The examination will begin with the placement of the speculum in the eye. The duration of the examination varies according to the visibility of the retinal vascularity, and the examination will end with the removal of the speculum from the eye. Ocean Sound Group; The ocean sound recording will continue to be played during the ROP examination. Control Group; No sound will be played before, during and after the ROP examination. Physiological parameters will be recorded at the 1st and 5th minutes after the procedure. (Video recordings will be evaluated by two experts for PIPP-R and PBIC). Video recording will be stopped.Ocean Sound Group;The ocean sound recording will be played at the 5th minute after the ROP inspection. Control Group; No sound will be played before, during and after the ROP examination.

LENS is a streamlined multicentre randomized placebo-controlled parallel-group trial investigating the effect of fenofibrate treatment on the progression of diabetic retinopathy/maculopathy

The purpose of this study is to evaluate the efficacy and safety of brolucizumab compared to panretinal photocoagulation laser (PRP) in patients with proliferative diabetic retinopathy (PDR). This evaluation will provide information that brolucizumab is non-inferior to PRP with respect to the change in best corrected visual acuity at Week 54.

The VOYAGE trial will assess diabetic retinopathy severity scale (DRSS) levels, through 112 weeks, while being managed with aflibercept as needed, among subjects who completed the 2-year PANORAMA trial (VGFTe-OD-1411) and were treated in a clinical setting prior to joining the VOYAGE study.

The purpose of this study is to evaluate the efficacy safety and tolerability of ultevursen administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene.

A recombinant adeno-associated virus serotype 2 (rAAV2) vector has been altered to carry the human RPE65 (hRPE65) gene. This vector has been shown to restore vision in animal models that resemble human RPE65-associated Leber congenital amaurosis (LCA), an incurable retinal degeneration that causes severe vision loss. The proposed study is an open label, Phase I clinical trial of subretinal rAAV2-CBSB-hRPE65 administration to individuals with RPE65-associated retinal disease. Five cohorts will be included in this trial. Cohorts 1, 2 and 4 will consist of individuals 18 years of age and older. Cohorts 3 and 5 will consist of individuals between the ages of 8 and 17, inclusive. Enrollment in Cohorts 3 and 5 will begin only after confirming the safety of rAAV2-CBSB-hRPE65 administration in the older groups of participants. This trial will lead to a greater understanding of the safety and thereby potential value of gene transfer in RPE65-associated retinal disease and will have implications for other forms of retinal degenerative disease amenable to this type of intervention. The goal of this clinical trial is to determine the safety of uniocular subretinal administration of rAAV2-CBSB-hRPE65 in individuals with RPE65-associated retinal disease. Ocular and systemic toxicity will be assessed prior to and following vector administration to determine if there are adverse changes that may be associated with vector administration.
