Filter by:The aim of this study is to evaluate sleep of patients with septo-optic dysplasia compared to patients with an isolated disorder of peripheral visual system and patients with corpus callosum agenesis since both visus defict and agenesis of corpus callosum might be present SOD but associated to other features / structural and functional anomalies. Included patients and their caregivers will be asked to compile standardize sleep questionnaires and a sleep screening through an interview will be scheduled. Patients will be asked to wear an actigraph on their non-dominant hand wrist for 7 days.
The objective of this project is to create richer tactile aids by using materials chemistry to create tactile sensations in tactile aids, as an alternative to traditional physical bumps, lines, or textures. These materials are commonly used in household products, but have not yet been used to enrich tactile aids. Successful outcomes are primarily the accuracy with which low vision or blind subjects identify objects made from tactile coatings versus traditional tactile aids. Other outcomes include time to completion of the task, or the number of distinctive categories that participants can identify.
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 mutationsin RPE65 gene.

The investigators are developing an assistive device, known as multiplexing prism that expands the field of view for individuals with acquired monocular vision (loss of an eye). The investigators are testing a simplified design and fitting protocol to provide field expansion for individuals with acquired monocular vision.

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
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.
This is a pilot study of a patient navigator intervention for people living with diabetes and at high risk of diabetic blindness. The investigators are assessing the feasibility and acceptability of the intervention in preparation for a clinical trial.
