NCT ID: NCT05703360 Not yet recruiting - Stroke Clinical Trials

Effectiveness of AV-stimulation in Immersive VR to Improve Visual Perception and Driving Performance

Re:DriVR
Start date: December 1, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to evaluate the effectiveness of an immersive virtual-reality (IVR) based stimulation program, in improving visual perception for people who have lost their driver's license due to perceptual or cognitive impairments. The main questions it aims to answer are: 1. Can the 6-week IVR stimulation program help improve driving performance? 2. Will participants experience improvement in visual detection and perception after training? Study Design Summary: - Participants will be randomized into a waitlist group or intervention-first group - The VR-based intervention will consist of training every 2 days for six weeks - Waitlist group will wait 6 weeks before starting intervention at study midpoint (week 7) - Intervention-first group will begin with intervention (week 1-6) and then stop intervention at study midpoint - Participants will complete tests related to driving performance, visual attention, and visual fields at the start of study, midpoint, and end of study Researchers will analyze data for changes from baseline in outcome measures.

NCT ID: NCT05637385 Not yet recruiting - Clinical trials for Central Visual Impairment

Training Oculo-motor Control to Improve Vision When Using a Preferred Retinal Locus

Start date: March 1, 2023
Phase: N/A
Study type: Interventional

When high-detail vision is lost due to a retinal disease such as macular degeneration, people see poorly, and have difficulty with eye movements (oculo-motor control). This preliminary study will investigate a potential behavioral intervention that may improve the ability to perform vision-related daily activities such as reading, recognising faces and watching television. The intervention involves many sessions that will train visual perception and eye movements over a period of a few months. Participants will have either lost central vision in both eyes or have normal vision (control group).

NCT ID: NCT05522595 Not yet recruiting - Clinical trials for Binocular Vision Disorder

Performance and Safety Evaluation of the S360 Medical Device Software.

ArgoS360
Start date: November 2, 2023
Phase: N/A
Study type: Interventional

The aim of this interventional, cross-sectional study is to evaluate the performance and the safety of the medical device software S360. This clinical investigation is performed in order to demonstrate the conformity of the medical device, when operating under the normal conditions of its intended use, in accordance with the General Safety and Performance Requirements pertaining to clinical evaluation of the device regarding the Medical Device Regulation (MDR) 2017/745 (EU).

NCT ID: NCT05249504 Not yet recruiting - Depressive Symptoms Clinical Trials

Effectiveness of AMICOPE Intervention to Maintain Self-Perceived Health and Intrinsic Capacity in Older People

EFICIS
Start date: April 1, 2022
Phase: N/A
Study type: Interventional

In their day to day, persons do from simple to more or less complicated tasks and activities (ie: stand from a chair, open a door, shopping, read, drive, play chess, remind an appointment...). Such ability to do things is called capacity. Intrinsic capacity is the combination of all the physical and mental capacities that a person has, and reach its maximum in the early adulthood and then declines as the person ages. Each kind of capacity declines at her own speed (which may be faster or slower according to each person lifestyle), and once drops below a threshold may lead to a reduction in quality of life and loss of autonomy. Nevertheless there are some actions that may be effective to prevent or slow such decline. To do so the investigators have design an intervention that combines several things of different nature (what is know as a complex intervention) called AMICOPE. The AMICOPE intervention is performed in the community or in primary care centers through 12 weekly group sessions of 2 h 30 min which combine structured and adapted physical activity, group dynamics to promote social support and address loneliness, social isolation and depressive symptoms, and dietary advice. Our study is addressed to persons over 70 with light problems in mobility, nutrition or mood state. The purpose of this study is to assess if the AMICOPE intervention is better than the standard advice to follow healthy lifestyles to improve or maintain self-perceived health, mobility, nutritional status an psychological wellbeing.

NCT ID: NCT04078529 Not yet recruiting - Fall Clinical Trials

Falls Prevention for Visually Impaired Older People

Start date: January 2020
Phase: N/A
Study type: Interventional

This study aims to examine the effectiveness of an intensive five day falls prevention training programme with a home evaluation and a home exercise programme, compared with a home evaluation and exercise programme alone for reducing incidence of falls and fear of falling, and improving confidence in functional ability and objective balance.

NCT ID: NCT03726606 Not yet recruiting - Cataract Clinical Trials

A Comparison of the Visual Performance of Trifocal Versus Extended Depth of Focus Intraocular Lenses

Start date: November 5, 2018
Phase: N/A
Study type: Interventional

We are conducting a trial evaluating the performance of trifocal versus extended depth of focus intraocular lenses. These lenses will be implanted in otherwise healthy individuals with visual problems due to bilateral cataracts. Patients must be seeking an improvement in their visual performance with a special focus on presbyopia correction.

NCT ID: NCT03591315 Not yet recruiting - Visual Impairment Clinical Trials

Clinical Study of Structural and Functional Evaluation of the Visual Pathway

Start date: July 2018
Phase:
Study type: Observational

Sellar area tumors such as pituitary adenoma, craniopharyngioma and meningioma, etc, commonly lead to visual impairment symptoms. Patients suffer from a loss of visual acuity (VA) and visual field defects (VF) due to a local compression on the optic chiasma by the tumor. In the management of these patients, it is an important goal to evaluate their visual function throughout the treatment, so as to predict the outcome of the visual function . Since the visual pathway contains a huge complex network of both structure and function, traditional simplex evaluation of VA and VF is obviously not enough. Former studies have revealed changes in the visual network and cortex structure in neurodegenerative diseases and optic neuritis, yet the functional and structural changes caused by local tumor compression and their relation to the visual cortex activity patterns needs further research. The objective of this research is to asses the visual function in patients with sellar area tumor 1 week preoperatively (baseline),72 hours postoperatively(checking point 1) and at 3 months follow up(checkpoint 2). By using multimodal evaluation including visual resting and task state fMRI, diffusion tensor imaging (DTI), etc. The investigators aim to reveal the changes in functional connectivity (FC), amplitude of low frequency fluctuation (ALFF), regional homogeneity (REHO) ,visual cortex activity patterns and tract-based spatial statistics (TBSS).
