Pseudoexfoliation syndrome (PXF or PEX) is an age-related systemic syndrome that targets mainly ocular tissues through the gradual deposition of fibrillary white flaky material from the lens, mainly on the lens capsule, ciliary body, zonules, corneal endothelium, iris and pupillary margin.

Pseudoexfoliation syndrome, often abbreviated as PEX[1] and sometimes as PES or PXS, is an aging-related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. [2] Its cause is unknown, although there is speculation that there may be a genetic basis.

2018年11月22日 · During cataract surgery in eyes with PES, surgeons have to cope with two main problems: poorly dilated pupils and zonular fragility. A poorly dilated pupil not only makes a small and difficult capsulorhexis and increases the risk of iris prolapse but also increases surgical risk, due to poor visualization of the lens during the surgery.

2023年8月23日 · Pseudoexfoliation syndrome (PES) is one of the most common causes of open-angle glaucoma, with a higher risk of vision loss, a higher maximum and mean intraocular pressure (IOP) at diagnosis, and a wider range of IOP …

2015年10月29日 · Diagnosis of PES is based on the observation of pseudoexfoliative material on nearly all the structures of the anterior segment of the eye. Slit lamp examination, including gonioscopy and pupillary dilation, represents the gold-standard procedures for the clinical diagnosis of PEG.

Thinner CCT in eyes with PES, both as it is an independent risk factor and as a result of artificially lower intraocular pressure readings, may be an illuminating cause for development and rapid progression of glaucoma in the patients with PES.

Ocular pseudoexfoliation syndrome (PES), which was first described by Lindberg, (1) is characterized by progressive and extensive production and accumulation of gray-white fibrillar material, called pseudoexfoliation material (PEM), in the basement membranes and extracellular matrices in eye tissues such as in the conjunctiva, corneal ...
