“…T h e close relation between PEX and IOP disturbances, was also proved by checking the mean IOP in the eyes with unilateral PEX. In the affected PEX-eye, the mean IOP was increased more than 2.0 mmHg and this is consistent with previous analogous studies (Aasved 1971;Kozart & Yanoff 1982, Madden & Crowley 1982Sugar 1984;Konstas & Dutton 1991;Stefaniotou et al 1990).…”

“…The abnor- malities of the iris vessels (Vannas 1969;Konstas et al 1991) precede the clinical features, i.e. an increased quantity of pigment may be clinically observed in the anterior segment (Sugar 1984;Konstas & Dutton 1991). For this reason the term 'clinically unilateral pseudoexfoliation' is accurately used.…”

“…Indeed, it has now been suggested that the pigmentary signs not only accompany, but precede the fully established condition (Wishart et al 1985;Jerndal 1986;Prince et al 1987;Rouhiainen & Terasvirta 1990;Konstas & Dutton 1991). Therefore, these signs not only facilitate the diagnosis of the disorder, but more significantly may even predict its development.…”

The frequency of exfoliation syndrome (EXS) was investigated in a group of Greek patients undergoing extracapsular cataract surgery. Five hundred and nine (509) consecutive cataract patients without any other manifest ocular abnormality were prospectively examined for the presence of EXS. Patients were clinically divided into 3 groups: group I (EXS group) consisted of patients in whom exfoliation material deposition could be seen; Group II (possible EXS group) comprised patients who demonstrated a number of pigmentary signs and group III (normal subjects) comprised patients with senile cataract and no sign of EXS. EXS was found in 140 (28%) of our patients, possible EXS in 119 (23%) and the rest (49%) had no evidence of EXS. Patients with EXS were older (mean age 73.8) when compared to the possible EXS group (70 years) and the control group (64.7 years). The IOP was significantly higher in patients with EXS (mean 15.5 mmHg versus 14.3 mmHg in the other two groups). Blue irides were significantly more common in patients with EXS (19%) than in the possible EXS group (14%) and the controls (4%). EXS is common in Greek cataract patients and this study has identified a large group of patients who may be at an early stage of development of the condition. EXS may predispose to the development of cataract in Greek patients.

“…Pigmentation in the angle is also often increased but irregular. [49][50][51][52]62,[64][65][66][67][68][69][70][71][72][73][74][75][76] Additional pigmentation is observed along Schwalbe line, termed a "Sampaolesi's line." 72,73,77 This finding is not exclusive to PXF, but can be seen in pigment dispersion syndrome and chronic inflammation.…”

Pseudoexfoliation (PXF) glaucoma is classically diagnosed by slit lamp visualization of white powdery deposits (PXF material) in a bull's eye configuration on the lens capsule. PXF glaucoma is the most common form of open-angle worldwide with an identifiable etiology. 1 The presence of PXF material is associated with an increased risk of developing glaucoma, but can be present in the eye without associated glaucoma. This disorder also has an association with narrow angles secondary to zonular weakness, increased rate and risk of cataract formation, and increased risk of complications during cataract extraction associated with zonular dehiscence. PXF glaucoma's primary manifestations and morbidity are ocular. However, PXF is a systemic condition with PXF material present throughout the body. The presence of PXF material has been weakly associated with cardiovascular and cerebrovascular morbidity and sensorineural hearing loss. 2-10 Unlike PXF and glaucoma, a direct cause-effect relationship remains to be clearly established between the presence of PXF material and the aforementioned systemic associations. PXF syndrome was first described by Lindbergh in the year 1917, followed by Vogt, and initially termed "glaucoma capsulare." The classic white flaky dandrufflike material was initially thought to originate from the lens capsule. 11 Immunohistologic and electron microscopy studies suggest the PXF material deposited on the lens capsule and throughout the anterior segment of the eye (ie, the angle, corneal endothelium, etc.) is a product of abnormal extracellular matrix material metabolism. 1 PXF is distinct from true exfoliation syndrome observed in glass blowers, where a schisis of the anterior lens capsule occurs. Recent molecular and genetic studies have revealed clues as to the molecular pathogenesis of PXF material formation and the association of PXF with the extracellular matrix and cellular metabolism. 12,13 This paper reviews current concepts in the medical and surgical management of PXF glaucoma.
