• To evaluate the safety of up to 3 additional courses of oral QLT091001 administered once daily for 7 days in subjects with LCA or RP caused by RPE65 or LRAT gene mutations who have been treated previously with a single 7-day course of QLT091001 in…
The goal of this study is to develop and investigate the effectiveness and cost-effectiveness of a stepped-care programme for visually impaired older adults to diminish subthreshold depression and/or anxiety symptoms and to prevent a full depressive…
What is the effect of image magnification on straylight values and is there a correlation between change in straylight values and change in visual acuity after pIOL (Artisan/Artiflex) implantation.
To confirm the previously reported negative predictive value of urine NTproBNP for ROP in large, multi center cohort of preterm infants.
Both RCTs and long-term follow-up studies are required to establish optimal fetal management and provide clinicians a better understanding of the impact of these early interventions on child development in order to improve the quality of antenatal…
Assess the quality and applicability of smartphone assisted and handheld fundus photography, compared to standard fundus photography. Photographs will be taken in non-mydratic and mydriatic conditions.
We want to assess the diagnostic performance of retinal nerve fiber layer (RNFL) thickness, macular ganglion cell layer (GCL) thickness, lamina cribrosa thickness and choroid thickness around the optic disc measured with SD-OCT in differentiating…
Primary objective: To evaluate change in RNFL thickness in RRMS patients followed for up to 36 monthscompared to a group of reference subjects (without neurologic or ophthalmic disease) todetermine whether the technology is sufficiently sensitive to…
The aim of this study is to determine if retinal defects and detachments can be detected by fundus photographs taken with the Optos 200Tx fundus camera.
To determine the influence of MFIOL on standard automated perimetry.
The objective of this study is to prospectively evaluate postoperative visual outcomes in a series of patients bilaterally implanted with the FineVision Micro F IOL versus those bilaterally implanted with the AcrySof® IQ ReSTOR® Aspheric +3 D…
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 objective of this project is to assess the effects and costs of ultra-thin DSAEK vs. standard DSAEK in order to determine whether the new technique is effective and cost-effective over the standard technique.
The purpose of this study is to identify and quantify the influence of medium opacity on RNFL and inner retinal layer thickness measurements using SD-OCT, as well as the effect of cataract on the filter measurements. Also to evaluate the…
To determine the proportion of successful alignment after treatment of infantile esotropia with Botox.
In the present study, we will investigate if a monocular visual field defect - due to primary open angle glaucoma - influences the anatomical integrity of the visual pathways.
The aim of this study is to compare levels of lateral inhibition between healthy subjects and glaucoma patients.
To demonstrate that combined (repeated) laser photocoagulation prolongs time to failure compared to anti-VEGF monotherapy.
The objective of this study is to evaluate the effect of different preventive strategies on the occurrence of macular edema after cataract surgery in non-diabetic and diabetic patients.
To determine the aberration pattern of the cornea from its shape.
