The aim of this observational and exploratory study is to describe the accuracy of gaze stabilization in the presence of abnormal vestibular and visual functions. Visually induced image movements are used as the basis for gaze stability for each…
The aim of this study is to compare the 3D designed prosthesis with the conventional made prosthesis.Study questions:- How is the 3D designed prosthesis compared to the conventional prosthesis? The final chosen workflow and settings will be applied…
The primary objective of this study is to compare the binocular uncorrected intermediate visual acuity (UIVA) at 66 cm under photopic conditions 3 months postoperatively, in a series of patients bilaterally implanted with the Acunex® Vario IOL…
The primary objective of the study is to explore the role of inflammation in the anterior chamber on endothelial cell loss in patients implanted with iris-fixated pIOLs. The secondary objective is to identify whether there is a correlation between…
The goal is to study the genetic background of childhood glaucoma in the Netherlands. We aim to study which mutations play a role in the pathogenesis of childhood glaucoma in the Netherlands and their prevalence. We will study the genetic mutations…
1. Primary objective:The primary aim of this study is to investigate the predictive value of OCT parameters at diagnosis for long-term (4-5 years after diagnosis) visual impairment (visual acuity, visual field) in children with a primary brain tumor…
Primary Objective: Compare visual acuity between adults born prematurely and adults of general population born at full term.Secondary Objective(s): o Compare other anatomical and functional ocular outcomes (retina, macula thickness, refraction,…
In this proposal, we will collect samples from both US and international corneal ulcers, identify etiology, AMR, and local host immune response, and correlate with presentation and outcome.Specific Aim 1. Worldwide surveillance of organisms…
The primary objective of this study is to be able to better assess progression of visual pathway damage in advanced glaucoma cases in particular. For this, we will use a unique combination of OCTA and dMRI techniques. In particular, we aim to relate…
To determine the diagnostic performance (sensitivity, specificity, and area under the ROC curve) of the current eye-movement based perimetry techniques, SONDA and BulbiCAM, as potential screening instruments for glaucomatous VF defects in ophthalmic…
The primary objective of this study is to compare the mean binocular DCIVA at 66 cm under photopic conditions 3 months after cataract surgery, in a series of patients, who previously underwent myopic laser surgery, bilaterally…
Primary Objectives• To evaluate prognostic factors of disease progression in subjects with Stargardt disease secondary to mutation in the ABCA4 gene • To further characterize the STGD1 patient population for future interventional clinical studies
This clinical trial will assess the clinical safety and performance of the CorNeat KPro.
1, Quantify and compare vascular and structural parameters obtained from AO-FIO, OCTA, OCT, and CFP in both healthy controls and glaucoma patients; 2, Investigate the correlation between these parameters and assess the additional value of vascular…
The overall aim of the Ageinglines cohort study is to better understand the biological ageing process and its association with the onset (pre)frailty and well-being in later life and to identify targets for delaying the biological ageing process…
Primary Objective: To explore the computations which occur in the brain which occur in visual disorders and determine how these differ from healthy controls. Specifically, we expect that the overall sensitivity (area under the curve) which reflects…
To demonstrate the clinical efficacy and safety profile of canaloplasty utilizing the iTrackTM Advance canaloplasty device performed via an ab-interno surgical technique achieves:1. Enhanced IOP reduction at 12 months due to the techniques ability…
The general objective is to validate a new non-invasive retinal imaging tool that allows the identification of relevant biomarkers in the retina in degenerative diseases of the brain and the eye by scattering and absorption properties.
The purpose of this protocol amendment is to meet the current and future needs of the MacTel Project’s collaborating investigators and continue meeting initial objectives. In addition, a third objective is to understand the mechanisms involved in…
The objective of the GLANCE project is to test the hypothesis that visual crowding in individuals with glaucoma isselectively raised under low-luminance conditions.If this hypothesis is supported, this would contribute to our understanding of the…
