Pseudoexfoliation of the lens capsule. This is most easily seen after dilatation, and is therefore sometimes overlooked Figures Aggarwal JL, Beveridge B. The higher IOP observed in pseudoexfoliation glaucoma can lead to more rapid optic nerve damage and visual field loss. Retrieved from ” http: Cyclodestruction of the ciliary body last resort.

Pilocarpine drops are poorly tolerated, however, because of accommodative spasm and induced myopia in younger patients. Many pedigrees have been published that demonstrate an autosomal dominant inheritance. There is also an increased risk of complications due to poor pupil dilatation and zonular weakness. In addition, there is an increased incidence of capsular rupture, vitreous loss and zonular dehiscence during cataract extraction in patients with pseudoexfoliation syndrome.

Iridozonular contact during accommodation as well as during normal pupillary constriction and dilation glaucoa the iris pigment epithelium and results in the deposition of pigmentary granules throughout the anterior segment. By preventing the liberation of pigment from the iris, laser iridotomy should allow the trabecular meshwork to clear itself and avoid further pigmentary deposition.

Pseudoexfoliation glaucoma commonly presents unilaterally with IOP that tends to escalate faster than among patients with primary open-angle glaucoma POAG. Patients with pseudoexfoliation syndrome and no evidence of glaucoma are generally not treated, but they should be followed every six to 12 months as they have an increased risk of developing glaucoma.
