Meet our team

DOPS 2021 will be organised by PhD students form Radboudumc and UMC Utrecht. Meet the members of our team:

Lude Moekotte


A year ago I graduated medicine at Maastricht University, and shortly thereafter I started my PhD at the Ophthalmology department at UMC Utrecht.

My PhD project focuses on elucidating the influence of systemic immune factors on the severity of CRB1-associated retinal dystrophies. Retinal dystrophies are inherited disorders of the retina where photoreceptors die, potentially causing people to become blind at a very early age. Although we know many variations of gene mutations causing this, there is still much we don’t know and treatment is still not possible. It feels great to contribute to increasing the knowledge we have on this, to be able to help people with retinal dystrophies preserve their vision for as long as possible. Please feel free to contact me for questions or more info! I’m always open for more contacts.

Carlyn Kouwenberg


I studied medicine at the Radboud University Nijmegen. In the years following my graduation I worked at the Neurology and Ophthalmology department as a medical doctor. In 2019 I started my PhD at the UMC Utrecht.

My PhD focuses on the systemic microcirculation in children with uveitis. Uveitis is a potentially blinding intraocular inflammatory disease. The fact that these patients frequently have severe vascular impairment of the eye including severe retinal vasculitis and diffuse vascular leakage, suggests systemic vascular and microcirculatory abnormalities. Investigation of microcirculation and potential biomarkers of vascular activation, growth and regeneration in children with uveitis would increase our understanding of the pathophysiology of this challenging vision threatening condition. This approach has as goal to improve the current diagnostic and therapeutic strategies, give better insight in the prognosis and bring us to a more holistic approach in children with uveitis.

Catherina Li


After graduating as a medical doctor at the Utrecht University, I started my PhD at Radboudumc in Nijmegen.

My PhD focuses on the natural history of Stargardt patients and explore the opportunities for therapy. Stargardt disease is the most prevalent form of inherited retinal diseases, accounting for 7% of all retinal dystrophies. Autosomal recessive mutations in the ABCA4 gene cause accumulation of toxic byproducts of the visual cycle, such as lipofuscine. Its disease course is characterized by progressive degeneration of the retinal pigment epithelium and photoreceptors. There are over 1000 DNA sequence variations reported. A selection of mutations is potentially amenable to antisense oligonucleotide (AONs), to correct the splicing defects. The aim is therefore to characterize the natural course of patients with AON-treatable mutations and understand the relationship between structural and functional biomarkers. Want to know more?

Janneau Claessens


I recently graduated as a medical doctor at Utrecht University. In February 2020 I started as a PhD student at the UMC Utrecht.

My PhD focuses on e-health in ophthalmology. The landscape of digital medicine has been rapidly changing over the last decade. Digital tools such as web-based eye exams and digital questionnaires can be of great value for increasing accessibility to eye care and tackling the increasing demand in this aging society. The acutely reduced access to healthcare during the COVID-19 outbreak also underlined the need for a paradigm shift in the delivery of eye care. I will be the executive researcher in an international multi-center trial on the validity, safety and cost-effectiveness of telemonitoring after cataract surgery. Want to know more?
