Filter by:The purpose of this double-masked, randomized, controlled, multiple-dose study is to evaluate the efficacy, safety, tolerability and systemic exposure of sepofarsen (QR-110) administered via intravitreal injection in subjects with Leber's Congenital Amaurosis (LCA) due to the CEP290 p.Cys998X mutation after 24 months of treatment
Subjects completing participation in study PQ-110-001 (EudraCT 2017-000813-22 / NCT03140969) will be given the opportunity to enroll into the extension study for continued dosing if available data support current and/or future benefits for the subject. Study PQ-110-002 will provide long-term safety, tolerability, pharmacokinetic (PK), and efficacy data of QR-110.
The purpose of this study is to evaluate the safety, tolerability and efficacy of a single escalating doses of EDIT-101 administered via subretinal injection in participants with LCA10 caused by a homozygous or compound heterozygous mutation involving c.2991+1655A>G in intron 26 of the CEP290 gene ("LCA10-IVS26").
The purpose of this study is to evaluate the safety and tolerability of QR-421a administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene.
A prospective natural history study with systematic assessments and uniform follow-up to provide a high-quality dataset for assisting in the design of future clinical treatment trials involving patients with CEP290-related retinal degeneration caused by the common intron 26 mutation.
To evaluate the anatomical and functional results of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling, endolaser photocoagulation and gas tamponade in management of optic disc pit (ODP) maculopathy.
The UK government's Crown report titled 'Review of prescribing, supply & administration of medicines' enabled optometrists to train for the qualification of independent prescribing (IP). The UK introduced IP for optometrists in 2009. The proposed research focuses on the role of IP optometrist in the acute ophthalmic services of Manchester Royal Eye Hospital (MREH). The study will compare IP optometrists to consultant ophthalmologists in the ability to diagnose, manage and prescribe medication for patients accessing these services. To achieve this comparison consenting participants will first have a clinical assessment with the IP Optometrist, where findings including diagnosis and management plan will be recorded onto a research proforma. The consultant ophthalmologist will be masked to the IP Optometrist's research proforma to prevent bias. The consultant ophthalmologist will then perform a clinical assessment on a second proforma and inform the participant of their diagnosis and management plan. Percentage agreement, kappa (κ) and weighted κ will be calculated for a range of parameters between the two proformas. Disagreement in diagnosis or management will be arbitrated by a separate ophthalmologist participating in the study with a specialty relevant to the participant's condition. The main objective of the research is to expand the limited base of evidence of of IP optometrists' ability to diagnose, manage and prescribe medication and to determine whether they work at least as safely and effectively as consultant ophthalmologists in acute ophthalmic services. It is the first study in this area since the advent of IP for optometrists, with only one previous study published before IP was introduced. The research will enable the type and frequency of conditions presenting in these services to be measured. Furthermore it will identify conditions that IP optometrists can manage independently and enable guidelines for these conditions to be developed.
Visual impairment can affect up to 70% of stroke survivors, but many do not have their vision adequately assessed in hospital. An unidentified visual defect can cause significant problems for recovery and quality of life. The Stroke Vision app (an application currently scaled for a 10" Android tablet) has been developed to act as a screening tool for visual problems in stroke survivors; to help identify visual problems earlier and thereby improve rehabilitation outcomes. The app includes a suite of tests for assessing the patient's acuity, their visual fields and to aid in the identification of visual neglect / inattention. Furthermore, it includes educational information on visual stroke in order to better educate staff, patients and their carers. This study seeks to validate the novel digital assessments included in the Stroke Vision app against the current methods used for screening (clinical examination by confrontation field testing). Both screening measures will be compared with the gold standard methods for visual assessments, Octopus perimetry for fields and paper-based methods for visuospatial neglect
1. To compare quality and usability of images taken by two different camera-systems without dilating the pupil. 2. To compare the retinal vessel diameters based on the images of to different camera-systems. 3. To detect changes in retinal vessel diameters while pregnancy and after delivery.
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
