In the eye, PEX syndrome manifests as the presence of pseudoexfoliative material deposits on the anterior lens capsule, ciliary body, zonules, pupillary edge, corneal endothelium, anterior vitreous, trabeculum and connective tissue in the eyeball (4-7).
Rise in IOP is probably caused by clogging of the trabeculum with debris7.
[8] compared the results of CLASS with NPDS and explained that, in the CLASS procedure, the aiming beam of the C[O.sub.2] laser is focused on the area of the Schlemm's canal and the pigmented trabeculum located underneath.
Electrical microstimulation focuses to the true cause of ocular hypertension, that is, the treatment of the dysfunctional trabeculum, while the rest of the therapy is focused on reducing the production of the aqueous humor or the exit of it through the unconventional route.
More nonoverlapping shots were placed when a greater extent of the trabeculum was visible.
INTRODUCTION: Pseudoexfoliation (PXF) first described by Lindberg (1) in 1917 and later on by Alfred Vogt (2) in 1918 means accumulation of grey white fibrogranular extracellular pseudoexfoliative material produced by abnormal basement membrane of ageing epithelial cells in trabeculum, equatorial lens capsule, pupillary margin of iris and ciliary body of the eye.
Hyaline deposits are seen in the conjunctiva cornea trabeculum and retina.14
(18,21-23) The disadvantage of viscoelastic materials is that they are not metabolized in the eye and will leave the anterior chamber through the trabeculum. Clearance of viscoelastic materials depends on the volume injected, the concentration and viscosity of the material, and the amount left in the anterior chamber.
(1) A possible mechanism for the development of PEX and its subsequent progression to glaucoma may be the combination of clogging up of the trabeculum by pseudoexfoliation materials and/or pigments released from the iris, as well as trabecular endothelial dysfunction.
Intraocular pressure (IOP) may be raised due to raised episcleral venous pressure or involvement of the trabeculum. In nodular anterior scleritis, single or multiple nodules are noted, which can become quite prominent and tender to palpation.
Latin or transliterated Greek words are used, without explanation, in such a way that is bound to puzzle all but the specialist reader: anamnesis (103); vivarium (105); ichthous (153), which is not the proper transliteration of the Greek acrostich "Jesus Christ, Son of God, Savior"; trabeculum (184).
Prootic jugular canal deep to osseous trabeculum. Posterior jugular opening confluent with emanation of hyomandibular nerve.
