Introduction Pseudoexfoliation syndrome.
Characterize for a deposit of an abnormal fibrillar material on the surface of some ocular and extraocular tissues
Described for the first time by Limberg 1917.
It is asociated with Glaucoma in a 40-60%

Propose
To determine by histophathology, inmunohystochemistry and ultraestructural studies the nature and origin of pseudoexfoliation material of the anterior lens capsule.
Methods
We obteined the product of the capsulorexis procedure realized during a conventional phacoemulsification and extracapsular cataract extraction in Asociacion para Evitar la Ceguera en Mexico (APEC).

Conclusions.
Because of the affinity SPA (+), the electrodense deposits of a fibrillar material found on the anterior lens capsule and the positive smear of the cromogen for collagen type IV, we suggest that this deposits can be the product of degradation of some glycoprotein present in some structures of the anterior chamber (iris, anterior lens capsule, endothelium and zonule) like in the basal membrane.
