Camiel Boon, MD, PhD, FEBO, explores the mysteries of central serous chorioretinopathy

Camiel Boon, MD, PhD, FEBO, is a professor of ophthalmology at Amsterdam University Medical Center and Leiden University, both in the Netherlands. During the 2025 congress of the European Society of Retina Specialists (EURETINA), he presented multiple talks, including explorations of central serous chorioretinopathy (CSC).

"We wanted to broadly cover this mysterious disease," Prof Boon said in an interview. "Some interesting new insights have emerged in terms of the pathophysiology. One of the key ones is actually that the choroid, and hyper-permeability and thickening of the choroid, is a key finding in central serous chorioretinopathy, and probably at the basis of the disease. This is very important because, of course, this might also indicate why certain treatments, such as photomimic therapy, are more successful for this disease." Prof Boon and colleagues presented several imaging findings which indicated specific leakage patterns from ICG angiography, a key imaging modality for cases of CSC.

Prof Boon also described the challenges of differential diagnosis, including atypical cases of CSC, and described the "relatively controversial" nature of CSC treatment. Watch the full video to hear all about his presentation.
