About this study

This observational study sets out to compare choriocapillaris flow deficits between healthy control subjects and patients with pseudoxanthoma elasticum. Pseudoxanthoma elasticum (PXE) is a rare, incurable hereditary disease caused by genetic mutations. The condition is characterised by excessive tissue mineralisation, which can result in a range of dermatological, vascular, and ophthalmological complications. Among these complications is the potential for visual impairment. The management of this condition is focused on the treatment of its complications. Degeneration of the retina and the choroid (the layer responsible for ensuring its vascularisation) occurs in the eye, resulting in premature degeneration. We would like to study the premature alteration of these structures, which could subsequently be used as an objective marker of the evolution of pseudoxanthoma elasticum.
