NCT ID: NCT06308601 Enrolling by invitation - Loneliness Clinical Trials

The Effect of Laughter Yoga on Loneliness, Anger and Salivary Cortisol Levels in Visually Impaired Individuals

Start date: May 16, 2024
Phase: N/A
Study type: Interventional

Purpose: This project aimed to examine the effects of laughter yoga, which is accepted as an international nursing initiative, on loneliness, anger and salivary cortisol levels in visually impaired individuals. When the national and international literature was examined, no project was found that measured the results of laughter yoga as an intervention for visually impaired individuals. For this reason, planning an original project in this field aims to contribute to the literature. Thanks to the evidence obtained, laughter yoga, an innovative approach, can be disseminated in institutions and organizations serving visually impaired individuals as an evidence-based practice that can improve the social skills of individuals. Scope and Target Audience: The project will be carried out with visually impaired individuals receiving services in the Disabled Persons Department within the Atatürk Provincial Public Library located in Konak district of Izmir. In this section, services are provided to 250 members who actively use the library and to visually impaired people from all over Turkey. Method and Expected Result: The project was planned in a randomized controlled, pre-test post-test, single-blind follow-up consultancy design. With this initiative, a social rehabilitation environment will be provided for visually impaired individuals by taking an approach based on respect, understanding and awareness. Laughter yoga is expected to reduce the level of anger and loneliness in visually impaired individuals. At the same time, laughter yoga is expected to reduce cortisol levels, which are known to increase when faced with stress factors, and increase serotonin, which is associated with happiness and vitality, and endorphine, known as the body's natural painkiller. With laughter yoga sessions, a social environment will be created where visually impaired individuals will have an active and independent experience. Thanks to the expected evidence, laughter yoga can be popularized both in visually impaired individuals and in individuals with other disabilities. Within the scope of protecting and improving health, laughter yoga can be planned to be carried out as a routine nursing practice in disabled centers. Thus, by creating an environment where visually impaired individuals and nurses come together, a more accessible health service will be provided to individuals with special needs.

NCT ID: NCT06224751 Recruiting - Clinical trials for Macular Degeneration

Developing Better Computerised Vision Tests (CVTV)

CVTV
Start date: April 2024
Phase:
Study type: Observational

Clinical vision measurements usually involve printed charts with an eye care professional interpreting patient responses to generate a score. Those scores determine the need for or outcome of treatment. Detecting change can be improved with strict procedures/scoring, lending itself to computerisation. This in turn allows integration with electronic medical records. Many eye tests could be computerised in this way. At Guys and St Thomas' NHS Foundation Trust, the investigators have developed and validated a computerised test of distance visual acuity, called COMPlog which is now in widespread use. The investigators now want to increase the range of tests available. There is also a need to longitudinally monitor for adverse change. Such monitoring must be developed to keep false positive and false negative change detection to a minimum. The aims of this two year linked program are to: Part A) validate an extended range of computerised vision measurement tests against their gold standard hard copy printed equivalents. Some of these tests are designed for use in children and all are meant to quantify both normal and impaired vision. Patients of all ages and visual function will therefore be recruited from St Thomas' Hospital. The specific tests we aim to validate are logMAR Letter Near Acuity, Word Near Acuity, Letter Contrast Sensitivity, Auckland Optotypes Picture Acuity, Low Contrast Letter Acuity, Stereoacuity and Vanishing Optotypes. Patients will undergo test-retest measurements with up to two of these. Part B) Iteratively develop an application for use in home monitoring of subjects at risk of treatable vision loss due to age related macular degeneration. All computerised tests in parts A and B will be performed on prototype software. Eye patients will be recruited as subjects. Patients recruited to part A will undergo tests on one day for up to an hour, subjects in part B will participate for between 1 hour and two months.

NCT ID: NCT06198114 Recruiting - Visual Impairment Clinical Trials

Effects of Multi Sensory Integration on Visual Impaired Children

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

Visual impairment is use to describe any kind of vision loss, whether it's someone who cannot see at all or someone who has partial vision loss. visual impairment is classified on the bases of visual acuity like mild, moderate, severe, profound, near total visual impairment, no light perception (NLP). Multisensory integration refers to a broad class of computations involving multiple sensory modalities in which information is integrated to produce an enhanced (or degraded) response.A Randomized control trail will be conducted at rising sun institute for disable children. Total sample size will be of 40 participants. After meeting the inclusion and exclusion criteria participants will be divided into two groups .Group A Control group will receive conventional therapy program. Place toys/objects inside and encourage the student to reach in and pull them out as well as put them back in. Give the student objects that can be put together and pulled apart.

NCT ID: NCT06197607 Recruiting - Visual Impairment Clinical Trials

Effect of Hand Exercises on Hand Grip Strength and Manual Ability in Children With Visual Impairment

Start date: November 28, 2023
Phase: N/A
Study type: Interventional

Development of the visual system immediately starts after birth via visual stimuli and interactions with the environment. The World Health Organization (WHO) has categorized visual impairments with respect to the best-corrected visual acuity as follows: blindness (Snellen visual acuity of 3/30), severe visual impairment (Snellen visual acuity between 6/60 and 3/30), moderate visual impairment (Snellen visual acuity between 6/18 and 6/60), and mild or no visual impairment (Snellen visual acuity of 6/18). The proper function of hands, particularly in delicate activities, depends on the interaction between the various regions of the brain, particularly, the sensory and motor cortex. Sensory stimulation can be used in such children to improve their manual dexterity and therapeutic interventions can be applied to gain hand strength. Developing skillful hands is a necessity in blind children as it often compensates for their missing vision. This study will focus on effectiveness of hand grip strength and manual ability with sensory stimulation in children with moderate to severe visual impairment. Theraputty hand exercises and sensory stimulation techniques will be used.

NCT ID: NCT06075147 Recruiting - Visual Impairment Clinical Trials

The SPECTRUM Study: An Observational Study to Learn More About How Well Aflibercept 8 mg Works in Treating Visual Impairment Due to Neovascular Age-related Macular Degeneration or Diabetic Macula Edema

Start date: February 15, 2024
Phase:
Study type: Observational

This is an observational study in which only data are collected from people who have already been prescribed aflibercept 8 mg by their own doctors. In this study, data from adults with visual impairment due to neovascular age-related macular degeneration (nAMD) or diabetic macula edema (DME) will be collected and studied. Visual impairment is any degree of vision loss that affects a person's ability to perform daily activities. nAMD is an eye disorder that causes vision loss due to the growth of abnormal blood vessels that leak blood or retinal fluid into the macula (the central part of the retina). nAMD is a leading cause of vision loss for people aged 50 and older. DME is a diabetes-related eye disorder. In DME, the macula swells up due to fluid leakage from damaged blood vessels, resulting in vision problems. Aflibercept 8 mg is a drug that is injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth and leakage of blood vessels at the back of the eye. Aflibercept 8 mg has been submitted for approval for the treatment of visual impairment due to nAMD and DME based on the results from 2 studies called PHOTON and PULSAR. This study will begin once approval is obtained. Currently, no real-world data are available for aflibercept 8 mg. The main purpose of this study is to collect more information about how well aflibercept 8 mg injection works in people with nAMD and DME. This study will include participants who have not received any prior treatment for nAMD or DME and participants who have. The main information that researchers will collect: the change in vision test scores called the best corrected visual acuity (BCVA) after 12 months of treatment. Data will be collected from February 2024 to September 2027 and will cover a period of up to 24 months per participant. The data will be collected using medical records and by interviewing the patients during regular visits that take place in routine practice. Researchers will observe participants from the first injection of aflibercept 8 mg until the end of the observation. In this study, only available data from regular visits will be collected. No visits or tests are required as part of this study.

NCT ID: NCT06000865 Recruiting - Glaucoma Clinical Trials

Glaucoma Rehabilitation With Action viDeo Games and Exercise - GRADE

Start date: September 9, 2023
Phase: N/A
Study type: Interventional

Falls are one of the most serious public health concerns for seniors, with significant medical and economic consequences. This concern is even higher in patients with peripheral field loss due to glaucoma because of the patients' compromised visual input. The investigators' project proposes an innovative, entertaining, easily accessible and enjoyable intervention for improving mobility and postural control function in glaucoma patients with peripheral vision loss, who are more prone to falls and suffer from fear of falling. The new intervention examined in this project can be implemented in current vision and balance rehabilitation programs, and may benefit patients with different types of visual impairment to minimize their risk of falls and improve their quality of life.

NCT ID: NCT05976880 Completed - Visual Impairment Clinical Trials

Grip Effects of Power Ball in Children

Start date: July 15, 2023
Phase: N/A
Study type: Interventional

A broad definition of visual impairment includes a wide continuum of visual function loss. Aspects of visual function include visual acuity, which is the capacity to resolve detail, and accommodation (capacity to concentrate), field of vision (the area that may be seen), colour perception, and light sensitivity. A child with cerebral blindness can nevertheless be able to perceive motion. There are numerous sources of prevalence information, each of which has drawbacks. One of the fundamental pillars of the major worldwide prevention of blindness project, VISION 2020 the Right to Sight, is the reduction of visual impairment and blindness in children in resource-poor nations. Refraction and poor vision services aid visually impaired children, especially those with genetic or congenital ocular defects and enable vision improvement.
