The main objective is to describe the interactions between physical sensory stimulations and high-level prior assumptions that give rise to visual perception. In two secondary objectives, we will advance novel model-based neuroimaging data-analysis…
The purpose of this study is to investigate the genotype of a large group of CSNB patients for which the phenotype is already known. We hope to increase our understanding of CSNB in order to improve diagnosis, to offer more realistic prognoses and…
The goal of this study is the development of a clinically verified functional imaging technique of the retina.
The purpose of this study is to collect and complement long-term clinical follow-up data from patients and families with choroideremia. We hope to increase our understanding of the clinical course of choroideremia.
Extent the current instrument for assessing autism in deafblind individuals with profound intellectual disability by Hoevenaars-van den Boom et al. (2008; 2009) to a protocol with manual for assessing autism in people with visual impairments, less…
The aim of this study is to compare the results of 2 methods for screening of eye function in children with the standard investigation by the orthoptist. The outcome of the tests and the time involved will be compared.Two screening methods will be…
Investigate clinical anomalies in the intraocular tissues, especially the accommodation system, in RDEB patients.
IRDs are genetically diverse (280 causative genes have been identified to date) (https://sph.uth.edu/retnet/) and have vastly different clinical manifestations, including age of onset, severity of disease, rate of progression, and structural and…
To compare different methods for visual field testing in young and/or neurologically impaired children, to determine which test is most useful in detecting visual field defects.
The study will help us to determine 1. the necessary type of (combined) examinations and 2. the sample size that is essential to evaluate (future) genetic therapy in Usher syndrome type 2 and USH2A associated nsRP.
1. To report the natural history of retinal degeneration in patients with biallelic mutations in the EYS gene.2. To identify sensitive structural and functional outcome measures to use for future multicenter clinical trials in EYS-related retinal…
1. To report the natural history of retinal degenaration in patients with biallelic mutations in the PCDH15 gene.2. To identify sensitive structural and functional outcome measures to use for future multicenter clinical trials in PCDH15-related…
PQ-110-004, is designed to evaluate if a mobility course using multiple light levels simulating real world conditions, can detect changes in vision in subjects with a phenotype representative of LCA Type 10 and therefore serves as an assessment tool…
