Filter by:A visual impairment (VI) is often associated with reduced psychological wellbeing. Music can be used in a variety of ways to promote psychological wellbeing. Music intervention studies demonstrate that listening to music can provide a distraction from unpleasant thoughts/feelings. Hence, music may serve as a catalyst to improve mood and relieve feelings of depression, anxiety, and stress. The purpose of this study is to investigate if it is feasible for people with acquired VI to self-deliver daily music listening (music alone or with mindful music listening instructions) for wellbeing, in participants homes, for four-weeks, and to collect data remotely on efficacy in reducing symptoms of anxiety and depression and treatment fidelity.
This project assesses the effect of bifocal cross-frequency transcranial alternating current stimulation (tACS) combined with visual training to improve visual recovery and orchestrated oscillatory activity in stroke patients suffering from visual field defects.
The present research process is a prospective clinical study that will be conducted under the auspices of the Democritus University of Thrace (DUTH) in the open accommodation structure for refugees and immigrants of Kavala, Kavala, Greece, and the Pre-Removal Detention Center (PROKEKA) for Foreigners of Kos, Kos, Greece. The study aims to assess the basic ophthalmological condition of the refugee/immigrant population and is developed in two main areas: 1. The recording of the ophthalmological care that the refugee/immigrant has received until his/her inclusion in the study through a structured questionnaire (eg previous examinations, spectacle utilization, pharmaceutical or other interventions, etc.) 2. The measurement of monocular best-spectacle corrected visual acuity in both eyes using a web-based visual acuity chart. Adult participants living in the two aforementioned centers will be recruited in a consecutive-if-eligible basis. All age groups will be proportionally represented (proportional age distribution).
A vision therapy protocol for vergence ability is mentioned. The purpose of this study is to evaluate objectively the change in the vergence responses of binocular and accommodative normal subjects after performing a classic vision therapy protocol. This study is an interventional, cross-over, and randomized study.
Visual screening is necessary among pre-school children as they found themselves in a critical period of visual developement. To date, there are no national vision screening program that has been implemented nationwide. Vision is a pilot feasibility multicentric cluster study comparing the sensitivity of "AFSOP 3 dimensional visual screening protocol in a population of 3 to 4-year-old pre-school children conducted in 4 kindergarten preschools in Paris with gold-standard ophthalmic examination confirmation.
Approximately 24,500 children and young people (CYP) in England have a visual impairment (VI). VI refers to a loss of vision that cannot be corrected with glasses or contact lenses. Low vision aids (e.g. magnifying glasses) can help CYP with a VI see more clearly. However, current low vision aids are not suitable for many of the activities CYP regularly engage in, such as watching TV or school lessons. SightPlus is an advanced head-mounted digital low vision aid for CYP and adults. SightPlus helps people with a VI use their remaining vision to see more clearly up close and at a distance. SightPlus was recently tested at Moorfields Eye Hospital in London with 60 adults with a VI. The results showed that adults could see more clearly while using SightPlus. The study proposed here aims to find out whether SightPlus can improve the vision and quality of life of CYP aged 8-16 years with a VI. For this study, 25 CYP will come to Sheffield Children's Hospital (SCH) for an 80-minute session with parents/guardians where they will have their vision tested, complete questionnaires measuring their vision-related quality of life and functional vision (i.e. what someone can see), and learn how to use SightPlus. CYP will then be asked to use SightPlus for four weeks. Parents/guardians will record the activities CYP use SightPlus for in a home diary. After four weeks, CYP and their parents/guardians will come back to SCH for a 90-minute session where they will have their vision tested with and without SightPlus, complete another vision-related quality of life and functional vision questionnaire, hand in their home diary, and complete a feedback form about their experiences of using SightPlus. This study will help us find out whether SightPlus can improve the vision and quality of life of CYP with a VI.
The use of tools is ubiquitous in our lives and allows us to expand the sensorimotor capacities of our body. Much research has been done on the subject in sighted people over the past decades. This work has mainly focused on the motor aspect of using the tool, neglecting the sensory aspect. However, any action involving a tool carries sensory information, for example in the use of the white cane by blind people. 26% (> 200,000) of blind people in France use a white cane to get around. By sweeping the cane on the ground, they use it as a sensorimotor extension of their body to extract information from the environment in order to locate a pedestrian crossing or possible obstacles. While it is well established that the tools increase the user's motor skills, we have only just begun to clarify how they also function as sensory extensions of the user's body and how this phenomenon is potentially dependent on constant use of the tool to compensate for a missing sense, as is the case with blind people using a cane. The aim of this study is to fill this important gap in our knowledge.
The trial will determine the impact of an information- and education-focused interventions on the anxiety levels, and patients' experiences as well as satisfaction of patients aged 10-14 and their caregivers during the MR examination.
This study aimed to measure optic nerve sheath changes in the intraoperative period in patients who underwent vitrectomy surgery and to investigate the intraoperative factors that may affect this. Standard anesthesia protocol will be applied to all patients participating in the study. Optic nerve sheath diameter measurements of the patients taken to the operating room will be made on the operating table by ultrasonography method. Standard anesthesia induction will be performed following SpO2 and ECG monitoring in routine anesthesia monitoring. Depth of anesthesia will be evaluated with routine hemodynamic data.
The purpose of this study is to evaluate the efficacy safety and tolerability of QR-421a administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene with early to moderate vision loss.
