Pseudoexfoliation syndrome

from Wikipedia, the free encyclopedia
Classification according to ICD-10
H40.1 Primary wide-angle glaucoma
ICD-10 online (WHO version 2019)

The Pseudoexfoliation (PEX) is a systemic disease with amyloidosis -like deposition of proteins in the front part of the eye and other organs .

Synonyms are: pseudoexfoliation lentis syndrome; Glaucoma capsulare; Exfoliation glaucoma; XFG; pseudoexfoliation glaucoma; PEXG; Exfoliation syndrome

It was first described in 1917 by the Finnish ophthalmologist John G. Lindberg

The name pseudoexfoliation was proposed by the American ophthalmologist Georgiana Dvorak-Theobald in 1953.

distribution

The frequency is given as 1.5 - 6% and increases with age. Women are affected 3 times more often.

root cause

The cause is not yet known; increased concentrations of transforming growth factor (TGF-β1), decreased activity of enzymes for proteolysis , creeping inflammation and oxidative stress are involved in the fibrotic deposition process.

Partial were mutations in LOXL1 - gene on chromosome 15 locus q24.1 found which encodes lysyl oxidase-like 1, a cross-linking matrix enzyme.

Variants in the CNTNAP2 gene on chromosome 7 at q35-q36 have also been described.

Clinical manifestations

Clinical criteria are:

Deposits can also be detected in other organs in the body, such as the heart , lungs , liver , kidneys or gallbladder .

therapy

The condition does not respond well to medication, so surgical treatment may be required.
