Active clinical trials for "Vision Disorders"

This study will determine whether blood biomarker changes predict sight-saving benefits of exercise.

The goal of this project is to quantify and computationally model the perceptual experiences of Argus II retinal prosthesis patients. The investigators will produce visual percepts in patients either by directly stimulating electrodes or by asking them to view a computer or projector screen and using standard FDA-approved stimulation protocols (as is standardly used for their devices) to convert the computer or projector screen image into pulse trains on their electrodes. Performance of patients will be compared to that of sighted control subjects viewing a simulation of the vision generated by Argus II in virtual reality.

This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.

This is a feasibility study to begin investigating the possibility that early use of near vision glasses will improve vision in infants at risk of Cerebral Visual Impairment (CVI), leading to further improvement in other areas of development. This active intervention, starting at either 2 or 4 months of age (depending on randomisation), could be more effective than waiting until a problem is detected before giving glasses. As this is a feasibility study, the investigators are looking at a small sample of babies (n=75) to see whether their parents/carers are willing to take part in a 3-arm study comparing two differently timed interventions to a control group, as well as looking at different aspects of the research plan in preparation for a larger final study.

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.

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.

Clinical register of visual rehabilitation activity and observational study on the validation of the VA LV VFQ questionnaire in the Italian context

Primary objective of this study is the development and validation of a web-based application for the examination of the distance visual acuity of normal- and low-vision patients.

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

A novel computerized visual acuity test was developed and tested on both healthy persons and patients with ocular conditions. Visual acuity outcomes of the computerized test will be compared to the Early Treatment Diabetic Retinopathy Study (ETDRS) in measures of reproducibility, accuracy and numbers of questions.
