To detect ophthalmic differences between patients and controles. To detect (early) changes in the retina in (pre)symptomatic RVCL disease carriers, in order to find a *biomarker* for disease stage and progression.
Identification of the proteins that are involved in neurite outgrowth in PDR. We want to determine what protein levels are increased in the vitreous by local production and which RNA transcripts are present in the fibrotic membranes of patients with…
The objective of the study is to map in a standardized way the phenotype of carriers with known LHON mutations. We want to study the natural course of persons with LHON mutations by examining patients several times. Further, we want to study a…
1. To determine if zinc supplementation in AMD patients has a direct measurable effect on the complement system explaining the mechanism through which this substance exerts its influence on AMD progression.2. To determine whether this proposed…
This study has the following goals: 1. Generation of normative values for full-field ERGs within single recording sessions according to ISCEV standard.2. To compare function (results of full-field ERG) with anatomy (retinal thickness on OCT) in…
The aim of this study is to investigate whether skin autofluorescence (AF) is predictive of postoperative PVR (and corresponding surgical failure) in patients being surgically treated for retinal detachment and to investigate some pathways which may…
Assess correlation between CFH polymorphism and the effect of laser treatment of drusen.
To perform an external (geographic and temporal) validation of predictive models for estimating the probability of PVR following primary RD using a subgroup of SNPs from a total of 197 in 30 candidate genes previously studied.
the study aims to answer the following question:are components of innate immunity in general, and the complementsystem in particular, correlated with and usefull as predictors for the occurrence of macro- and/or microvascular complications in a high…
To determine the natural history and long term (10 years) outcome of CSR.
What is the contribution of the different variations in the C1-inhibitor gene to the disease AMD?
1) To demonstrate that the FcRn functions as a transporter and protector for vitreous IgG and monoclonals (Avastin, Lucentis) and show that monoclonal therapeutic antibodies are transported over the RPE via the FcRn. 2) To investigate if…
Quantification of the incidence of postoperative CME in DSAEK patients.
The key objectives of this study are to identify both the genetic background and pathophysiological mechanisms that underlie CSC. To achieve this we will: 1) Perform genetic analysis and ophthalmological examination in a cohort of sporadic CSC…
The objective of this study is to analyse the retinal oxygenation in adults with the Oxymap T1 in patients with amblyopia and untreated or treated (vitreo-) retinopathies and compare them to a reference group of healthy eyes of amblyopic and Coats…
The objective of this study is to investigate the use of retinal oximetry in children, between five and seventeen years of age, with (vitreo-) retinopathies and oxygen-related diseases of the retina by means of an Oxymap T1 fundus camera.
To study the efficiency of visual information processing in patients with retinal disorders.
Development of a laboratory assay
To collect data in order to create a registry that can be used for research in PXE, partly with an international questionnaire, and to measure PPi, ENPP1 activity, anti-retinal antibodies and cytokines, and retinal calcification in all patients…
To determine whether functional and/or structural retinal biomarkers or circulating biomarkers are able to differentiate people with mild cognitive impairment (MCI) within the type 2 diabetes (T2D) population (this we will be able to do in the…
