Filter by:A Phase 1, open-label, non-randomized, dose-escalation study, where approximately 9 eligible patients with retinitis pigmentosa will be enrolled sequentially in up to 3 dose cohorts of RTx-015. Enrolled patients will receive a single, unilateral intravitreal injection of RTx-015 in the study eye at Visit 3 (Day 0) and be followed for a total of 12 months.
A Phase 1 Open-Label, Multiple Ascending Dose Study to Evaluate the Safety and Tolerability of Intravitreally Administered VP-001 in Participants with Confirmed PRPF31 Mutation-Associated Retinal Dystrophy
Oral disulfiram (Antabuse®) has been shown to improve image-forming vision in animal models with retinal degeneration due to its ability to decrease Retinoic Acid synthesis and consequently reduce hyperactivity in the inner retina. The investigator will aim to evaluate the impact of oral disulfiram on the vision of patients with retinal degeneration who are being treated with the drug in the management of their concurrent alcohol use disorder.
This trial is meant to evaluate the safety and efficacy of ZM-02 in Retinitis pigmentosa (RP) patients. Unilateral intravitreal injections (IVT) will be given into the subject's Study Eye.
This study will assess the effect of 2 different colours of light on colour vision in adults with retinitis pigments (RP). Participants will be 18 years or above with a genetically confirmed molecular diagnosis of RP. After informed consent, participants will have their letter chart vision and colour vision measured in their study eye. They will then be they will be randomly allocated to one of 2 groups. The study team will not know which group they have been assigned to. Group 1 will be given a coloured-light hand-held torch and be asked to apply it to their study eye for 3 minutes at home each morning between 8 - 10 am for 28 days. Group 2 will be given a different colour hand-held torch and be asked to do the same. All participants will have their letter chart vision and colour vision measured at the end of study on day 28 (+ 7 days).
Glaucoma, age-related macular degeneration (AMD), retinitis pigmentosa, RP, diabetic retinopathy (DR) are the most common blinding eye diseases in the world. Vision and visual field are often severely impaired, quality of life is reduced, and personal and family burdens are heavy. This kind of low vision people, can use visual AIDS and other instruments for visual rehabilitation training, maximize the function of residual vision, improve the quality of life. Beyes, HOLA, Acesight and OXSIGHT are among the latest eyeglasses devices that are expected to improve the quality of life for people with low vision. This research group intends to recruit advanced patients with primary glaucoma, AMD, RP, DR and other common blinding eye diseases who visited Zhongshan Ophthalmology Center of Sun Yat-sen University from June 2021 to December 2022 to study the changes of visual function and quality of life after wearing this new type of head-worn visual aids, and analyze relevant factors combined with clinical data. To evaluate the effect and influencing factors of the new head-mounted visual AIDS on patients, and provide theoretical basis for subsequent clinical research.
This clinical trial aims to test the safety and feasibility of using a non-invasive ultrasound device to stimulate retinal nerve cells and restore vision in patients with age-related macular degeneration. Previous studies have shown that artificial stimulation, such as electric and optic stimulations, can partially restore vision, but these methods are invasive and pose surgical risks. The study aims to develop a non-invasive method for retinal stimulation. The investigators will follow the FDA guidelines to limit the ultrasound power and adhere to all clinical trial regulations to ensure all participants' safety. The main questions the investigators aim to answer are: - Is using high-frequency ultrasound safe using a wearable device for localized retinal neural activity stimulation? - Does the stimulation through the device restore vision in patients with age-related macular degeneration? Participants in this study will be asked to undergo Optical Coherence Tomography (OCT) scanning before and after the ultrasound stimulation to evaluate the device's safety. Then, they will receive five stimulation-rest cycles and complete a questionnaire to report what they see and how they feel during the device's operation.
Typically, clinical research participation favors a specific demographic group, and little research exists on how trial attributes affect participation. As such, this study seeks to analyze data from different demographic groups and check for recurring trends that could provide valuable insights for future retinitis pigmentosa patients.
Pilot, randomized, observer and participant masked, sham and fellow eye controlled, interventional clinical device trail to evaluate the safety and effectiveness of the 2C-QD device to improve visual function in adults with advanced Retinitis Pigmentosa (RP).
This study is designed to assess and to evaluate the therapeutic effect of retrobulbar injection of autoserum in the treatment of retinitis pigmentosa.
