The major goal of this study is to develop a systematic and stepwise approach for dry eyes. First, it will be evaluated whether Tes glasses are a diagnostic tool for dry eye diseases. Second, it will be evaluated or it can make a distinction between…
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.
The project consists of three concrete goals:1)Compare symptoms and patterns of fatigue of visually impaired adults with a control group of adults without a visualimpairment.2)Develop an intervention aimed at treating symptoms of fatigue in visually…
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…
Development and validation of the D-AI KIDS and the D-AI YA:Currently there is no standardized instrument that measures visually impaired children*s and young adults' participation based on the nine ICF-CY domains. The primary objective of this…
To study neuronal and ophthalmological characteristics of a newly detected clinical entity called slow vision which hampers visual perception and attention of the affected patients.
To measure the quality of peripheral visual field in healthy volunteers and the effect of different corrective lenses on the peripheral visual field.
To determine the effect of tube position in the anterior chamber on the corneal endothelium.
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.
A comparison of the PR-OCT and conventional ways of examination of patients, being slitlamp biomicrsocopy combined with stand alone SD-OCT, and fluorescein / ICG angiography, or glaucoma screening.
The primary objective is to assess the IOP and MAP in sitting and side lying position in healthy subjects and in patients with NTG.
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…
The objective of this study is to determine the optimal background light intensity for the examination of the visual field with a perimetry test and to confirm the de Vries-Rose, Weber's and Ferry-Porters law in patients with glaucoma.
To study IVCM backscatter measurements as a usefull measurement to decide between surgical indications.
The primary objective of this study is:- To determine the potential difference in MT and RNFLT between treated and untreated patients with anisometropic or strabismic amblyopia. Secondary objectives are:- To determine the potential differences in MT…
To determine the efficacy of quantification of vitreous floaters captured by SLO-imaging technique for Nd:YAG vitreolysis for persisting vitreous floaters.
Primary objectives1) To clarify which components of spatial remapping are impaired after damage to the posterior parietal cortex.2) To correlate spatial remapping abilities with scanpath quality in visual search.3) To examine whether different…
The objective of this study is to determine the light and dark adapation time and contrast sensitivity in changing background light conditions.
The objectives of this pilot are (1) to test and develop an experimental setup to determine contrast sensitivity, visual field and adaptation time at high light conditions. (2) To perform a pilot study with 10 healthy subject.
The primary objective is to obtain OCT data for children aged 4 to 10 diagnosed with non-syndromic craniosynostosis and to compare these to the normal reference values.
