Topography of Slowed Dark Adaptation in Pseudoxanthoma Elasticum: PROPXE Study Report 1

CONCLUSIONS: Patients with PXE exhibit significant slowing of both cone- and rod-mediated dark adaptation, particularly in regions prone to BrM calcification. These findings suggest that dark adaptometry and assessment of BrM calcification can serve as clinical tools for evaluating disease severity and monitoring progression in PXE, enabling earlier interventions before the onset of exudative MNV or …
