Filter by:Our goal is to determine the cellular scale changes that occur in subjects who have disease progression due to pentosan polysulfate sodium toxicity
The purpose of this study is to evaluate incidence and prevalence rates of the study endpoints (pigmentary maculopathy [PM]/ pigmentary retinopathy [PR]/Any, PM/PR/ pentosan polysulfate sodium [PPS], and PM/PR/Non-PPS) in relation to PPS exposure, and in participants with interstitial cystitis (IC) but not exposed to PPS; changes in visual acuity (VA) over time; participant treatment journey leading to PPS treatment, and potential risk factors associated with the occurrence of PM/PR/PPS.
Retinitis Pigmentosa is characterized by a progressive disappearance of photoreceptors, responsible for a progressive and severe loss of vision. People Retinitis Pigmentosa therefore encounter a large number of difficulties in daily life, specifically for: - Visual research - Visuo-motor coordination in tasks requiring fine motor control - Visuo-motor coordination in mobility tasks This study aims to assess the difficulties in the daily life of subjects with Retinitis Pigmentosa at a very advanced stage unsing, quaify of life questionnaires, simplified locomotion tasks in real situation and a posture task. They are proposing a new test adapted and carried out in real situations, in binocular and monocular vision, making it possible to finely assess locomotion especially for "very low vision" patients. This test will also ultimately make it possible to better evaluate the effectivements, that is to say to observe and quantify objectively by a score the performance progression obtained for locomotion tasks related to the visual recovery generated by the treatment.
To communicate with the observer and guide his gaze on the canvas, painters have developed different stylistic processes that artists, in the manner of scientists, have acquired on the functioning of human visual perception. This direct communication between the artist and the observer is strongly impacted for people with visual impairments. In order to improve the accessibility and autonomy of visually impaired people in museums and to allow each observer to feel the visual and emotional experience closest to the original work of the artist, it is essential to identify the modifications. perceptive generated by the constriction of vision
To evaluate whether the use of the Argus II retinal prosthesis improves the confidence and self-esteem of patients with advanced retinopathy pigmentosa
