Active clinical trials for "Vision, Low"

The purpose of this study is to demonstrate that two investigational treatment regimens have the potential to result in a superior visual acuity improvement as compared to a ranibizumab pro re nata (PRN=as needed) treatment regimen.

The purpose of this study is to identify ocular biomarkers that can predict the success of phacoemulsification with bilateral AT LISA try 839MP (Carl Zeiss Meditec AG) implantation to achieve satisfactory post-post-operativly spectacle-free vision. Social, biometric and patient reported outcomes will be evaluated.

Patients with parkinson disease (PD) usually reduced the dose the levodopa after received deep brain stimulation (DBS). However, studies seldomly mentioned about the influences on non-motors systems after the reduction. Our study focused on the changes after DBS and attribute them to the levodopa variety.

The goal of this study is to examine the ability of optical head-mounted display technology to enlarge the visual field of patients with severe visual field loss due to retinal dystrophy and to improve mobility and patient-reported outcomes.

Mobile electronic devices (MED) including, smartphones and tablets, offer a new type of assistive technology for visually-impaired people (VIP). They offer the possibility to replace optical magnifiers for those with mild impairment, and braille or auditory for those with severe visual loss, using standard consumer devices, which are relatively cheap and convenient. However not all VIP and rehabilitation professionals are familiar with the devices and their potential. In this study VIP who are interested in purchasing a MED will be recruited and trained. The effectiveness of this training will be determined by assessing the usage of devices by the participants from completion of training to 6 months, using questionnaires, and by remote monitoring of their MED. Validated questionnaires will be used to measure changes in quality of life, depression, adaptation to vision loss, and ability to carry out everyday tasks, before and after training, and 6 months later. Ongoing support has been found to be important when introducing users to new technology, in the form of volunteers to provide assistance and advice. The standard "training course only" model will therefore be compared to a scheme in which each participant is paired with a "buddy" (a university student) who can provide continuing support by visiting the VIP regularly at home.

This project is working on orthoptic rehabilitation for low vision people. The aim of the project is to assess the interest and integration of this rehabilitation device used at home, in low-vision private practice and at the hospital. It leads to develop and evaluate an innovative device to integrate and adjust monitoring of patients according to their need and their progress, to create new interactions with the patient, enabling the orthoptist to stay in touch with his patient at home between rehabilitation sessions and to obtain a more fine and objective analysis of the exercises done by the patient. Using an eye tracker and a digital tactile screen with data uploads allows the practitioner to observe the progress objectively. It also leads the patient to a better understanding of his/her visual behavior and of the effects of rehabilitation. Therefore, it will be easier to adopt better strategies.

The purpose of the study is to compare the effect of intravitreal injections of ranibizumab and aflibercept on systemic VEGF levels in DME patients in a detailed time course.

The purpose of this study is to evaluate the efficacy and safety of brolucizumab in treatment of patients with visual impairment due to diabetic macular edema (DME).

This study aims to validate an observer-rated assessment titled "Functional Low-Vision Observer Rated Assessment (FLORA-20)", which comprises 20 functional vision tasks commonly performed in or around a blind individual's home environment. This study shall be carried out with individuals who have an implanted visual prosthesis device. There are no new implantations or changes to the original implant or external wearables being studied or tested. Additionally, data from the study shall not be used alter standard of care or the user's treatment options.

The purpose of this study is to evaluate how visual acuity assessed with Peek Acuity (a cell phone application to check visual acuity) among preschool and school-aged children 3 to less than18 years of age (1) compares to the standard visual acuity exam in the ophthalmology clinic and (2) performs as a screening test for ocular abnormalities that warrant referral for an eye exam.
