Active clinical trials for "Vision Disorders"

The objective of the present study is to develop a therapeutic, adaptive, and enjoyable game that will be used by children with CVI between the mental age of 3 and 12 years. Such a game will be easy to use and implement by the children, their parents, and therapists.

An individual senses the world and reflects feedbacks via independent behaviors. Such precise collaboration of the sensory and behavioral systems is fundamental to survival and evolution. When a sensory modality is altered, the behavioral system has the potential to fit in a substitute modality. However, the specific dynamics of human behaviors in response to sensory loss remain largely unknown due to the paucities of representative situations and large-scale samples. Here, the investigators focused on thousands of human infants who suffered varying degrees of visual stimuli deficiency in early stages, while their behavioral systems remained sensitive and thus retained high behavioral plasticity. Having access to this unique population provides an unprecedented opportunity to investigate the effect of diverse visual conditions on the behavioral system and develop a domestic apparatus for screening visual impariment of infants.

Several recent clinical trials have highlighted the potential role of Product in promoting eye health.product whose structural and functional characteristics make it a promising bioactive compound in the prevention of several human diseases as well as in the maintenance of a good health status. it might relieve eyestrain in people using computer monitors as suggested who conducted a double-blind randomized clinical trial by enrolling visual display terminal workers and prescribed them product or placebo. Study outcomes were objectively evaluated by using a proper instrumentation to measure eye muscle endurance. Subjects receiving Product experienced a significant relief from eyestrain compared to the placebo group.

Cerebral Palsy (CP) is the most common childhood disorder that occurs with a lesion in the developing infant brain, seen in 2-3/1000 live births. CP is a posture, movement and tone disorder that occurs due to prenatal or postnatal causes. It is not progressive, but since the anatomy of the lesion and the physical development of the individual are not completed, the course of the disorder may vary throughout life. Accompanied by motor dysfunctions, it varies according to clinical types. In addition to this, various visual, sensory and behavioral problems, speech disorders that cause learning difficulties and cognitive problems can also be observed. Ophthalmic disorders are the most common problem in CP and can also affect the developmental process of the patient. Since ophthalmic disorders and neurological deficits are associated in CP, the relationship between neurological disorder and ophthalmic disorders has been investigated in the literature. The aim of this study is to establish the Turkish validity and reliability of the Visual Function Classification System (VFCS) specific to individuals with Cerebral Palsy (CP).

Elderly with visual impairment (VI) who undergo community eye screening often do not attend tertiary follow-up even if significant eye diseases are detected. Investigators evaluate an incentive-care scheme (ICS) to improve the attendance rates of tertiary eye-care visits of participants following community eye screening.

The overall goal of this research proposal is the early prediction of the emergence of CVI and its characteristics on the basis of neuroimaging data. The different steps that will be taken to achieve this goal will be: To characterize CVI deficits in children; To correlate the CVI characteristics with their motor profiles; To characterize brain lesions in children with CVI; To link the motor profile, CVI profile and brain metrics of the children. Over the last 10 years, 488 children with and without CP have consulted at the CVI clinic in Leuven. All these children had a comprehensive visual perceptual assessment, cognitive evaluation and an ophthalmological assessment. Summarizing these data results in a quantitative visual perceptual profile for each individual patient. The goal is to prospectively extend this database to a number of 600 children. The project's primary objective is to relate the presence of CVI to the motor profiles of these children. Of these 488 children, 300 have an MRI available. The goal is to analyze the retrospective MRI data of this clinical group and to prospectively extend this database by reassuring newly registered children will receive MRI with DTI. This will allow the investigation of the correlation between the brain metrics and the CVI characteristics in a large cohort.

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.

the purpose of the study is to evaluate the software usability and patient's adherence from five vision rehabilitation centres. In addition, the effect and benefits of a customizable telerehabilitation program were tested.

This study will highlight differences in cortical activation between asymptomatic and symptomatic patients.

Disability glare is described as "halos" or "starbursts" around bright sources of light that can cause discomfort and reduce vision. The cornea is the clear "window" at the front of the eye, but certain conditions such as a previous infection can leave a scar. Corneal scars can cause disability glare by scattering and spreading incoming light instead of allowing it to focus on the back of the eye (retina) to get a crisp image. In this study, the corneal scar will be analyzed using a new device that measures scar density (Pentacam), and a relationship with disability glare will be made. This can help us further understand disability glare and make better decisions in the future on when to treat these scars to help patients see better.
