The Antwerp Research Group for Ocular Science (ARGOS) focuses on translational research of the anterior segment of the eye using techniques of regenerative medicine and tissue engineering. We conduct projects from bench to bed side by a unique combination of clinicians and basic researchers. Our focus is on the ocular surface with research lines on regeneration of the epithelium, stroma and endothelium of the cornea and conjunctiva. The approach is multidisciplinary thanks to local, national and international network connections. Our expertise includes the development and optimization of primary cell isolation and cell culture protocols without using animal products, designing biological and synthetic scaffolds, and testing their biocompatibility. Through our partnerships, we have the opportunity to work with 3D printing, micro-contact printing and with different types of hydrogels. Specifically, we successfully completed a phase I / II study in which limbal corneal epithelial stem cells were expanded ex vivo on an amniotic membrane for transplantation. We are further building on the acquired expertise: we are specifically focused on the development of a conjunctival substitute and smart scaffolds for endothelial transplantation. The latest project concerns cornea-on-chip in which a three-dimensional dynamic tissue environment is created to better model human physiology in a lab environment. The Visual Optics Lab Antwerp (VOLANTIS) studies the optical aspects of the human eye, with special attention to normal and pathological refractive development. To this end, we develop statistical and biomechanical models that innovatively describe normal eye growth, as well as the inter-individual differences that exist in the general population to better understand myopia and other refractive disorders. The unique collaboration between clinicians, optometrists, mathematicians, and physicists has already led to fundamental advances in the early detection of keratoconus and predicting the future course of the disease, allowing individualized treatment to be offered to the patient. Another line of research focuses on how glare from bright lights can affect daily functioning in tasks such as driving a vehicle safely. Finally, research is also being carried out on pediatric cataracts to gain more pathophysiological insight into this developmental disorder and the results of the surgical treatment.

In the coming years the VOLANTIS research group, plans to conduct several studies related to visual optics and ocular biomechanics. Overall, these studies may be grouped into three topics. The first is refractive development and eye modelling, which studies how the eye grows and how this can be described as a mathematical model. Such models will look at e.g. how during eye growth the different components of ocular biometry interact with each other to first bring the eye in focus ('emmetropia') and then maintain this condition as the eye continues to grow. Other studies look at what happens if such a balance is disrupted or how it is accomplished in pathological eyes (e.g. premature infants or infants operated for cataract). Within the European OBERON project, we will also develop a new type of model that combines the biomechanics of the eye with its optical function as a platform for testing new treatments in virtual clinical trials. This 'opto-biomechanical' model will need close interactions with our European partners. The next study topic is keratoconus, a disease that gradually deforms the cornea, leading to a considerable loss in visual quality. Early detection of the disease and its possible progression is very important in its management as it allows the patients to preserve a higher visual quality through timely treatment. To this end, we are working on machine learning systems that can tell ophthalmologists whether an eye has keratoconus and, if so, if it is in a progressive state. Another project looks at improving the popular 'crosslinking' treatment that increases corneal elasticity and stops the progression. To do this, we need to develop corneal elasticity maps that can inform ophthalmologists what areas of the cornea need treatment. Although the current methods to develop such maps are very computationally intensive, we will use new methods that have not yet been tried to speed up this process from several hours to minutes, making it clinically useful. Finally, we will study straylight and dark adaptation, which refers to being blinded by bright lights ('glare') and the time needed to recover afterwards. These phenomena can play a major role in traffic safety as drivers may be blinded by the headlights of oncoming cars. Since it is not yet understood at what level of glare the safety risks for safe driving become too high, we will organize a study to test the effect of a bright light source on performance in a driving simulator in a darkened room. The outcomes of these experiments will later be formulated as advice to legislative authorities to improve traffic safety.

The focus of my research group is the elucidation of the molecular basis of genetic epilepsies. State-of-the-art genetic strategies resulted in the identification of several novel disease genes, such as de novo KCNQ2 mutations in neonatal epileptic encephalopathy. Using non-neuronal and iPSC derived neuronal cel models, we further study the effect of mutations on normal gene functioning. We have a close connection with the Neurology department at the UZA Hospital, where the PI is responsible for the epilepsy clinic. In the last years we have grown from a genetic research lab to a lab that works from bed (deep phenotyping of patients) to bench (genetic diagnosis and functional characterization) and back to bedside (therapeutic strategies).
