Filter by:This study will train participants (young people and older adults) to do a visual task, and will assess whether this results in changes in behavioral assessments. In some participants, we will be also testing whether MRI measures (cortical thickness, functional connectivity) change with training.
This pilot study aims to assess the interest to add an auditory pathway morphological analysis during the MRI exploration of visual pathway in visually impaired children.
This clinical trials aims to evaluate Tests Performance on a New Digital Orthoptic Platform.
The Baltimore Reading and Eye Disease Study (BREDS) is a two year study to determine the prevalence of vision problems in an early school age population with reading difficulty. Comprehensive vision and reading tests will be administered to 400 students at participating schools in the Baltimore City Public School system. A secondary goal is to examine the impact of vision treatment on reading performance. Children with refractive error or convergence insufficiency will be provided treatment free of charge. The investigators will evaluate the impact that the treatment has on vision function and reading performance.
Study of efficacy and safety of 0.5 mg ranibizumab in Chinese patients with diabetic macular edema (DME)
Because people who have both diabetes and visual impairment have high risk for foot problems, prevention of ulcers and amputation is a high priority. Usual care in diabetes self-management education (DSME) is to teach them to seek sighted assistance for regular foot examination, yet clinical experience suggests that this advice is seldom heeded. One possible solution is to teach use of the nonvisual senses of touch and smell for a systematic, thorough foot self-examination. The purpose of this pilot study was to compare the efficacy, acceptability, and feasibility of nonvisual foot examination with usual care (examination of the visually impaired person's feet by a sighted family member or friend).
The purpose of this study was to find out whether a method of nonvisual foot inspection, using the senses of touch and smell, helps people with diabetes and visual impairment to find new foot problems when they are in early, easily-treated stages. All people in the study had regular foot inspections by podiatrists. The results include how people feel about the method, whether they actually did check their feet it, and whether the method helped them to discover foot problems themselves.
The AGE (Active Geriatric Evaluation) aims to develop a brief assessment tool adapted to the primary care setting.
This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant® after 6 months of treatment. In the study arm Lucentis will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.
