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...

BACKGROUND/AIMS Recent studies have revealed patients with ocular hypertension to have thicker than normal central corneas and those with normal tension glaucoma to have thinner than normal ones, as determined by ultrasonic pachymetry. Since corneal thickness measurements and applanation tonometric estimates of intraocular pressure (IOP) correlate positively, monitoring of the former parameter ...

PURPOSE Glutathione S-transferases (GSTs) are a family of enzymes that inactivate xenobiotics and endogenous end products formed as secondary metabolites during oxidative stress. In humans, GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0, and T0M0) are associated with a variety of pathologic processes including certain ophthalmologic diseases. METHODS We compared the prevalence of GSTT1 and GS...

Background: Globally, glaucoma is the leading cause of irreversible blindness. Pseudoexfoliation glaucoma is the most common form of secondary open angle glaucoma. Purpose: To determine the prevalence and characteristics of pseudoexfoliation glaucoma (PXG) among newly diagnosed glaucoma patients in Eye Foundation Hospital Ikeja, Guinness Eye Center, Lagos University Teaching Hospital and Desere...

The depth of the anterior chamber was measured in 34 eyes with pseudoexfoliation but without glaucoma and in 334 normal controls. No significant difference was found.

Aim. To study the outcome of cataract surgery in eyes with pseudoexfoliation without signs of glaucoma. Methods. This prospective study was done over nine months on patients with pseudoexfoliation undergoing small incision cataract surgery. Only patients with normal intraocular pressure (Central Corneal Thickness Corrected), normal cup disc ratio and open angles were included. Patients on anti-...

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...

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 ...

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...
