Filter by:The aim of the study is to assess visual function from neonatal age to 36 months of age in infants at risk of visual impairment due to brain lesion or ocular pathology
This randomized controlled trial will evaluate the effect of intravitreal faricimab or fluocinolone acetonide (FAc) intravitreal implant compared with observation on long-term visual acuity following treatment of choroidal melanoma with iodine-125 plaque brachytherapy.
To assess the use of contact lenses with transitions technology to improve glare, light sensitivity and overall visual comfort in patients with visual impairment.
Longitudinal, prospective, single-center observational study of visual impairment after stroke. Population: Patients admitted with acute ischemic stroke at the Regional Stroke Unit at Oslo University Hospital who are assessed to not have more serious neurological deficits than to be eligible for a prospective observational study of visual impairment. National Institute of Health Stroke Scale (NIHSS) will be used for screening of the patients eligible for the study with cut off of NIHSS 20. Based on the number of patients admitted to our center to include 120 patients in the StrokeVIS study. The study aims are: 1. To determine the prevalence of visual impairment in stroke patients in the acute phase and after 3 months. 2. To compare visual impairment in those treated with EVT and those not. 3. To determine the sensitivity and specificity of the Vision Screening Assessment (VISA) tool for detection of visual impairment in stroke patients. 4. To assess possible association between brain MRI lesions and visual impairment in stroke patients in the acute phase. 6) To assess any cognitive deficits at 3-month follow-up that could impact visual function. Inclusion criteria: 1. Acute ischemic stroke and NIHSS < 20 2. Age ≥18 years. 3. Written informed consent of the patient or oral informed consent witnessed by a doctor. Exclusion criteria: 1. NIHSS < 20 2. No willingness and ability of the patient to participate in all baseline and follow-up examinations. Duration of study participation: 3 months.
Clinical register of visual rehabilitation activity and observational study on the validation of the VA LV VFQ questionnaire in the Italian context
The purpose of this study is to examine the effectiveness of a psychotherapy (non-medication) treatment, Brief Cognitive Behavioral Therapy for Suicide Prevention, in reducing suicide ideation and attempts for people with physical disabilities.
Age-related Macular Degeneration (AMD) is an age-related eye disease resulting in vision loss. Persons with AMD not only experience a gradual loss of ability in independent living, but also profound impairment in psychosocial well-being.The multimodal, expressive arts-based intervention (EXABI) that emphasizes imagination and creativity can be an engaging, enjoyable, and safe process of empowerment. This study aims to investigate the effectiveness and process of an expressive arts-based intervention in enhancing psychosocial wellness and adjustment to gradual vision loss of persons with AMD. This current study will adopt a 2-arm randomized controlled design with treatment-as-usual control. Upon screening for inclusion exclusion criteria, baseline data will be collected; and eligible participants will be randomized into either an 8-week Expressive Arts-based intervention group or Treatment-As-Usual control group.
Implantable collamer lens (ICL) is one of the most effective operation for high myopia. Due to refractive correction changed, and prism effect of the spectacle removed, in the early stage after ICL implantation, binocular function might be dysfunction, leading to asthenopia, blurred vision, double vision and so on. This study will recruit the high myopia subjects that scheduled for ICL implantation, purpose to investigate the binocular vision alternations and brain activation that impacted by ICL implantation.
Seniors deal with considerable visual demands (driving, communicating, traveling) and reduced vision affects their quality of life, ability to enjoy activities, and age-in-place. Vision loss has a heavy, increasing, economical and social burden. It can also have substantial impacts on caregivers physically, psychologically, and financially because one tends to miss more work, be less productive, and thus have fewer job opportunities. This registration will describe the clinical portion of a larger study designed to evaluate both the feasibility and effectiveness of the Re:Garde Program, a Virtual Reality (VR) visual training program for older adults to help maintain visual perception to promote quality of life and prolonged independence. In partnership with our care partners the investigators will implement the Re:Garde Program at an interprofessional clinic and as part of a loaning program for older adults to use in the home. The clinical portion of this study will look at how effective the Re:Garde program is at maintaining or improving visual perception, ability to conduct activities of daily living (e.g. read, drive, cook, exercise etc.), general wellness, and quality of life. The feasibility of implementing this program in the two settings will be evaluated separately as part of the full protocol.
Viewing strategies are strategies used to process visual Information. Many children with visual impairment seem to lack systematic viewing strategies. However, it is unknown how viewing strategies differ between children with normal vision and children with (cerebral) visual impairment. In addition, viewing strategy training is often adopted in clinical practice, but till date there is no scientific evidence about effectiveness of this approach. The current project has two goals: (1) to measure viewing strategies used by children with normal vision, children with ocular visual impairment and children with CVI, and (2) to evaluate whether training viewing strategies results in more efficiënt visual Information processing.
