What causes Pseudoexfoliation syndrome?

Is pseudoexfoliation serious?

Why is it called pseudoexfoliation?
It is called ‘pseudoexfoliation’ to differentiate it from true exfoliation which is due to heat or infrared related changes in anterior lens capsule.
How common is exfoliation syndrome?
It’s estimated that, globally, 30 percent of people over age 60 have some form of anterior exfoliative deposits. Exfoliation syndrome goes beyond the build up of anterior segment debris. Changes in the lens capsule and iris are also seen in PXS.
Is pseudoexfoliation genetic?
Pseudoexfoliation syndrome is a major cause of glaucoma that has a strong familial association. Recent studies have confirmed that LOXL1 is a major gene associated with both XFS and XFG.
Does pseudoexfoliation always lead to glaucoma?
If you have pseudoexfoliation syndrome, does that mean you will develop glaucoma? Although there are patients in whom pseudoexfoliation material is seen but there is no sign of glaucoma, it is estimated that approximately 40 – 50 percent of patients who have pseudoexfoliation syndrome will eventually develop glaucoma.
Is Pseudoexfoliation glaucoma hereditary?
What is Scandinavian glaucoma?
There is a high prevalence of pseudoexfoliation syndrome in Scandinavian countries, where it is estimated that 50 percent of open-angle glaucoma is caused by pseudoexfoliation syndrome. On the other hand, it is relatively rare among African Americans and Eskimos.
How is pseudoexfoliation diagnosed?
Pseudoexfoliation (PXF) glaucoma is classically diagnosed by slit lamp visualization of white powdery deposits (PXF material) in a bull’s eye configuration on the lens capsule. PXF glaucoma is the most common form of open-angle worldwide with an identifiable etiology.

What is the pathophysiology of exfoliation syndrome?
Disease. Exfoliation (pseudoexfoliation) Syndrome is characterized by the fibrillar deposits in the anterior segment of the eye. The deposits have been found on and in the subconjunctival tissue, pupillary margin, ciliary epithelium, lens epithelium, lens capsule, iris pigment epithelium, trabecular meshwork,cornea,zonules, orbital soft tissues,…
What is pseudoexfoliation glaucoma (PXF)?
This raises pressure inside the eye (called intraocular pressure, or IOP) and can damage the optic nerve. This is called pseudoexfoliation glaucoma(PXF glaucoma) and can lead to loss of vision. What Causes PXF? Doctors do not know for sure why people get PXF.
