Frequency, Phenotypic Characteristics and Progression of Atrophy Associated With a Diseased Bruch's Membrane in Pseudoxanthoma Elasticum

Abstract

Atrophy of the outer retina and the retinal pigment epithelium is a common finding in PXE patients characterized by early onset and fast progression with subsequent visual loss independent from CNV. This suggests that atrophy is the natural endpoint of Bruch's membrane disease. Phenotypic similarities with multifactorial geographic atrophy in age-related macular degeneration suggest common pathogenic pathways at the level of Bruch's membrane.
