Autofluorescence Imaging of the Skin Is an Objective Non-Invasive Technique for Diagnosing Pseudoxanthoma Elasticum

Quantitative Fundus Autofluorescence in Pseudoxanthoma Elasticum.

Purpose To quantify lipofuscin-associated fundus autofluorescence in patients with pseudoxanthoma elasticum (PXE), a model disease for Bruch's membrane pathology. Methods In this prospective, monocenter, cross-sectional case-control study, 49 patients with PXE (mean age: 46 years, range 18-62) underwent quantitative fundus autofluorescence (qAF) imaging with a modified scanning laser ophthalm...

MR imaging in pseudoxanthoma elasticum.

Gri:inblad-Strandberg syndrome known as pseudoxanthoma elasticum (PXE) is a rare connective tissue disorder, the inheritance of which shows both autosomal and recessive characteristics [1]. The disease most commonly involves the skin , eyes , cardiovascular system, and gastrointestinal tract [2]. The vascular connective tissue supporting the retina, known as the Bruch membrane, tends to calcify...

Pseudoxanthoma elasticum

Pseudoxanthoma elasticum (PXE) is a genetic metabolic disease with autosomal recessive inheritance caused by mutations in the ABCC6 gene. The lack of functional ABCC6 protein leads to ectopic mineralization that is most apparent in the elastic tissues of the skin, eyes and blood vessels. The clinical prevalence of PXE has been estimated at between 1 per 100,000 and 1 per 25,000, with slight fem...
