background: pseudoexfoliation syndrome is one of the most common identifiable causes of open angle glaucoma. it has unknown etiology and pathogenesis. infection, possibly viral, is one of the proposed pathogenic mechanisms in this condition. in the present study the presence of herpes simplex virus (hsv) in specimens of anterior lens capsule of patients with pseudoexfoliation syndrome has been ...

The iris vascular bed of eyes with pseudoexfoliation syndrome has been studied with electron microscopy. Two of the eyes suffered from painful glaucoma, whereas the third showed normal intraocular pressure. The following changes were observed: (1) deposits of pseudoexfoliation material lying adjacent to the endothelial wall; (2) thin vessel basement membrane, sometimes even interrupted; (3) ext...

objective: pseudoexfoliation syndrome (pex) leads to some problems in the eye surgery specially cataract surgery. as the prevalence of eye problems is high in diabetic patients, we meant to assess the prevalence of pex in diabetic patients. materials and methods: in this cross-sectional study, 400 type 2 diabetic patients aged 50 or above who referred to yazd diabetes research center were selec...

The presence of pseudoexfoliation material on the surface of an intraocular lens (IOL) is a rare finding. We report a series of seven cases with different patterns of pseudoexfoliation material deposition on the posterior chamber IOLs, recognized 2-20 years after cataract surgery. Six patients had an IOL implanted in the capsular bag and one in the ciliary sulcus. Two patients had undergone pos...

introduction: pseudoexfoliation syndrome (pex) is the most common identifiable cause of secondary glaucoma, the prevalence of which varies considerably among different ethnicities. the aim of this study was to assess the prevalence of pex in diabetic patients older than 50 years. methods: in this descriptive, cross-sectional study 400 diabetic patients older than 50 years referred to the yazd d...

Pseudoexfoliation syndrome is a systemic age-related disease in which abnormal extracellular material is produced and accumulates in many ocular tissues. Its ocular manifestations involve all of the structures of the anterior segment as well as conjunctiva and orbital structures. The presence of pseudoexfoliation should alert the physicians to the increased risks associated during and after cat...

We present cases of primary open angle glaucoma patients without previous history of pseudoexfoliation who developed pseudoexfoliative materials on the anterior surface of the intraocular lens after cataract surgery. Among 5 unilateral pseudophakic pseudoexfoliation cases, 3 showed a more advanced state of glaucoma in the affected eye. The other 2 cases showed progression of glaucoma in the aff...

Pseudoexfoliation (PXF) syndrome is a well-recognized clinical entity of considerable clinical significance. It is associated with poor mydriasis, cataracts with weak zonular support, secondary glaucoma and possibly with biochemical abnormalities, such as elevated homocysteine and systemic diseases involving the cardiovascular and central nervous system. There have also been some recent studies...

PURPOSE To report two cases of spoke-like intraocular lens (IOL) opacification that resembles pseudoexfoliation of the crystalline lens. METHODS Case series presentation. RESULTS Patient 1 developed a circle of spoke-like opacification on the anterior IOL surface 7 years after phacoemulsification. Patient 2 had paracentral anterior surface IOL opacification 18 months after cataract extracti...

purpose: to compare total plasma homocysteine (thcy) levels in cataract patients with and without pseudoexfoliation syndrome (pxs). methods: in this case-control study 29 (15 female and 14 male) cataract patients with pxs and 29 (16 female and 13 male) cataract patients without pxs were enrolled. fasting thcy level was measured using high-performance liquid chromatography and compared between t...
