Active clinical trials for "Retinal Diseases"

Cataract is an important cause of blindness and visual impairment worldwide. At present, the only effective treatment method is surgery. The visual function of most patients can be significantly improved after surgery, but there are still 5-20% of patients whose visual function cannot be improved after surgery. Previous studies have found that the surgical complications and postoperative visual function of cataract patients are closely related to the condition of the fundus, but the current fundus camera cannot perform clear fundus imaging of cataract patients, and the existing potential visual inspections, such as retinal visual inspection, are also inaccurate. Predict postoperative visual acuity. Therefore, there is an urgent need for a reliable postoperative effect prediction system for cataract patients to provide reference for both ophthalmologists and patients. This study intends to collect patient medical record information and traditional/ultra-wide fundus photos and other multi-modal data. Firstly, this study will use artificial intelligence technology to enhance fundus photos of cataract patients to obtain clearer fundus photos. Then this study will use both medical record information and traditional/ultra-wide fundus photographs to predict postoperative vision and visual function of cataract patients.

Background: Preterm infants undergo serial eye examinations during their hospital stay to monitor for the development of a specific disease termed "retinopathy of prematurity". While those examinations are known to cause significant pain and stress, the current standard of care (sucrose and local anesthesia) is not adequate in terms of alleviation of pain. Purpose: The goal of this clinical trial is to test the effectiveness of dexmedetomidine for pain management in preterm infants undergoing routine eye examinations. The main questions it aims to answer are: Does dexmedetomidine reduce the pain scores of preterm infants during and shortly after eye assessments in comparison to placebo (saline 0.9%). Does dexmedetomidine cause more adverse effects than placebo. In this crossover study participants will receive either dexmedetomidine or saline 0.9% intranasally 30 minutes before the examination, on top of the current standard of care. The participants will be monitored closely for 5 hours to note differences in adverse effects. The researchers will use video monitoring to assess the pain scores using a standardized and validated scoring system.

Retinopathy of prematurity (ROP) is a widely known retinal vascular disorder in preterm infants and a leading cause of visual disability or blindness in children. Advances in antenatal care have resulted in an increase in the survival rate of infants with extremely low birth weight (BW). Approximately 90% of infants who develop ROP do so by a postmenstrual age of 46.3 weeks. In certain patients with or without treatment, the retina may fail to fully vascularize or may develop vascular abnormalities, thus demonstrating persistent avascular retina (PAR) or anomalous vessel findings at the periphery. Because of the advent of technologies such as ultrawide-field fluorescein angiography (UWFFA) persistent vascular abnormalities can be detected more readily and investigated.

Experimental data suggest that GLP-1 promote endothelial cell growth and angiogenesis which may have beneficial effects on the cardiovascular system but harmful effects on the retina . This project investigate the possible link between incretin therapy and Severe Diabetic Retinopathy. The prevalence of severe DR in patients exposed to incretin therapy (GLP-1 analogs or DPP4 inhibitors) is compared to that in non-exposed patients to these antidiabetic classes.

This is a prospective, observational study designed to evaluate the long-term safety and efficacy of RGX-314. Eligible participants are those who were previously enrolled in a clinical study of DR without center involved-diabetic macular edema (CI-DME) in which they received SCS administration of RGX-314. Enrollment of each participant in the current study should occur after the participant has completed either the end of study or early discontinuation visit in the previous (parent) clinical study. Participants will be followed for a total of 5 years post-RGX-314 administration (inclusive of the parent study). As such, the total study duration for each participant may vary depending on when they enroll in the current study following RGX-314 administration in the parent study.

To validate new screening instruments for eye disease, increase eye care access in underserved communities, and provide a scientifically implemented method to set up programs for eye disease screening.

This prospective study aims to validate if NeoRetina, an artificial intelligence algorithm developped by DIAGNOS Inc. and trained to automatically detect the presence of diabetic retinopathy (DR) by the analysis of macula centered eye fundus photographies, can detect this disease and grade its severity.

This randomized controlled trial will evaluate the effect of intravitreal faricimab or fluocinolone acetonide (FAc) intravitreal implant compared with observation on long-term visual acuity following treatment of choroidal melanoma with iodine-125 plaque brachytherapy.

Diabetic retinopathy is frequent, potentially severe with visual threat, health costly and represents a major public health problem. However, screening compliance for retinopathy remains too low in France, approximately 40% patients with diabetes laking diabetic retinopathy screening for at least 2 years. DIABeyeIA is a prospective pilot study evaluating the effectiveness and acceptability of diabetic retinopathy screening in 11 pharmacies in Normandy (north of France) using a non-mydriatic portable retinophotograph enhanced by artificial intelligence software. The main goal of this work is to evaluate a potential increase rate of diabetic retinopathy screening, compared to the actual rate (64% in France). Secondary goals are faisability, satisfaction and economical considerations for implementation of such a new screening program.

This study "A Long-Term Follow-Up Study in Subjects Who Received an Adeno-Associated Viral Vector Serotype 2 Containing the Multi-Characteristic Opsin Gene (vMCO-I) Administered Via Intravitreal Injection" is an observational study and will be conducted following Good Clinical Practice (GCP)- International Conference on Harmonization (ICH) guidelines. Eligible subjects satisfying all inclusion and none of the exclusion criteria will be enrolled. All subject who completed the parent clinical study (NSCT/CT/18/01) will undergo safety and efficacy assessments up to 5 years post study drug injection
