Filter by:The purpose of the study is to determine whether HG004 as gene therapy is safe and effective for the treatment of Leber Congenital Amaurosis caused by mutations in RPE65 gene.
This study seeks to determine the extent of the visual capabilities that can be restored in hemianopic stroke patients by a multisensory training technique and evaluate changes in the brain that the training induces. The effectiveness of the technique will be evaluated in two interventional contexts: patients whose blindness is long-standing and stable, and another in which intervention is as soon as possible after the stroke.
The goal of this retrospective observational study is to [learn about the correlation between hyperbilirubinemia and retinopathy of prematurity in preterm infants. The main question it aims to answer are: • To evaluate the possible effect of neonatal jaundice linked to the presumed protective antioxidant action of bilirubin on the development of ROP, compared to a control group which, although presenting ROP, did not develop jaundice.
A Single Arm, Pivotal, Open Label, Multicenter Clinical Investigation to Evaluate the Clinical Safety and Performance of the CorNeat Keratoprosthesis, for Treatment of Corneal Blindness
The study will begin with an explanatory/training session where individuals with low vision will learn to use the V-NAV (Vortant NAVigation tool) indoor navigation app, and will have the opportunity to try it for a few representative tasks. The main activity includes a take-home trial, an extended unstructured period to emulate the post-purchase experience of users, during which participants will have the opportunity to use the V-NAV in their everyday lives. Data will be collected from the users to measure the relative advantage of V-NAV compared to the user's current indoor navigation method.
This study aimed to relate and compare the performance of 4 types of red-tinted contact lenses (CL) with the Total Error Score (TES) from the Farnsworth-Munsell 100 Hue test on colour deficient subjects. Only 6 subject with colour vision defect was tested in this study.
The aim of our study is to examine the effects of eight sessions of online social skills training given to visually impaired adolescents on social skills, self-efficacy, social phobia and social integration. Forty visually impaired adolescents between the ages of 13 and 19 participated in the study. Participants were divided into control and training groups. 20 adolescents were included in the education program. All participants included in the study were evaluated using the Sociodemographic Information Form, Social Skills Assessment Scale for Children, General Self-Efficacy Scale, Child and Adolescent Social Phobia Scale, and Social Integration Questionnaire.
To demonstrate improved color vision in subjects with color vision deficiencies while wearing color-correcting lenses and after color-correcting lense use.
One of the most challenging tasks for blind and visually impaired individuals is navigation through a complex environment. The goal of the present multidisciplinary study is to increase spatial-cognition abilities in people who are blind or visually impaired through training with the previously-developed Cognitive-Kinesthetic Rehabilitation Training to improve navigation, and to investigate the resultant neuroplastic brain reorganization through multimodal brain imaging. In accordance with National Eye Institute (NEI) strategic goals, this multidisciplinary project will promote the development of well-informed new approaches to navigational rehabilitation, memory enhancement and cross-modal brain plasticity to benefit 'cutting edge' fields of mobile assistive technologies, vision restoration and memory facilitation for the aging brain.
This is a Phase 1/2 Study to Assess the Safety and Efficacy of OCU400 in patients with retinitis pigmentosa associated with NR2E3 and RHO mutations and in patients with LCA due to mutation(s) in CEP290 gene (OCU400-101). To document prospective eye pathology in the above subjects Investigators will also conduct a Natural History Study (OCU400-104)i This is a multicenter study, which will be conducted in two phases and will enroll up to a total of 24 subjects in the OCU400-101 and 100 subjects in the OCU400-104 study.
