SteRilizing Eye SoLution to ImprovE Patient ComFort (RELIEF)
Retinal DiseaseThis is a randomized, double-masked study to evaluate the tolerability and safety of IRX-101 versus 5% povidone-iodine (PI) in subjects receiving intravitreal anti-VEGF injections. The study will be conducted in up to 15 centers in the United States (US).
Clonidine as Pain Relief During ROP Eye Examinations
Retinopathy of PrematurityPain2 morePreterm infants are at risk of developing ROP (retinopathy of prematurity), an eye condition that can cause blindness. Preterm infants born before gestation week (GA) 30 are therefor screened regularly with eye examinations. These eye examinations are painful and despite a lot of research no clear method of pain relief have been found. Since pain in the preterm infant can lead to both short- and longterm negative consequences an effective pain relief during these examinations are of importance. In this study we will investigate if Clonidine can be effective as pain-relief during ROP eye examinations.
Oral Metformin for Treatment of ABCA4 Retinopathy
ABCA4 RetinopathyStargardt Disease2 moreBackground: ABCA4 retinopathy is a genetic disease in which the ABCA4 protein is absent or faulty. It can cause waste material to collect in the eye and may cause cells to die. The cell death can lead to vision loss. Researchers want to see if an oral drug called metformin can help. Objective: To see if metformin is safe and possibly helps to slow the rate of ABCA4 retinopathy. Eligibility: People age 12 and older who have ABCA4 retinopathy and have problems with their vision. Design: Participants will be screened under a separate protocol. Participants will have a medical and family history. They will complete a questionnaire about their vision and daily activities. They will have a physical exam. They may have blood drawn through a needle in the arm. Participants will have an eye exam. Their pupils may be dilated with eye drops. Their retina may be photographed. Participants will have a visual field test. They will sit in front of a large dome and press a button when they see a light within the dome. Participants will have an electroretinogram. It examines the function of the retina. They will sit in the dark for 30 minutes. Then their eyes will be numbed with eye drops. They will wear contact lenses that can sense signals from the retinas. They will watch flashing lights. Participants will have optical coherence tomography. This non-invasive procedure makes pictures of the retina. Participants will have fundus autofluorescence. A bright blue light will be shone into their eye. Participants will take metformin by mouth for 24 months. Participants will have study visits every 6 months. Participation will last for at least 36 months....
RGX-314 Gene Therapy Administered in the Suprachoroidal Space for Participants With Diabetic Retinopathy...
Diabetic Retinopathy (DR)RGX-314 is being developed as a novel, potential one-time gene therapy treatment for the treatment of diabetic retinopathy, a chronic and progressive complication of diabetes mellitus. Diabetic retinopathy (DR) is a sight-threatening disease characterized in the early stages by neuronal and vascular dysfunction in the retina, and later by neovascularization that leads to further deterioration of functional vision. Despite the availability of current treatments, diabetic retinopathy remains the leading cause of vision loss in working-age adults, those between the ages of 20 and 74. Existing treatment with anti-VEGF agents, although shown to be effective, are limited by short therapeutic half-lives, which then require frequent intravitreal injections over the patient's lifetime, resulting in increased risk of associated adverse events and significant treatment burden. Due to the burden of treatment, patients often do not closely adhere to treatment regimens and experience sub-optimal outcomes and a decline in vision. RGX-314 is being developed as a potential one time treatment for diabetic retinopathy, which may deliver advantages over conventional treatments, such as potentially providing a longer duration of therapeutic effect and intervening at an earlier stage of the disease.
Bevacizumab Treatment For Posterior Zone I ROP
Retinopathy of PrematurityType 1 retinopathy of prematurity in zone I represents the most severe type of ROP and has the worst prognosis. It is unknown whether low-dose bevacizumab will be successful in these severe cases. Also unknown is the timing and extent of peripheral retinal vascularization after low-dose bevacizumab compared with the standard dose. The current study will evaluate whether doses of 0.063 mg and 0.25mg are effective as treatment for type 1 ROP, with ROP and retinal vessels all in zone I.
Safety Study of rAAV2/8-hCYP4V2 in Patients With Bietti's Crystalline Dystrophy (BCD)
