Abstract
To evaluate the correlation between the amount of pseudoexfoliation (PXF) material on the anterior lens capsule, pigment in the iridocorneal angle, presenting intraocular pressure (IOP) and severity of glaucoma in patients with PXF glaucoma/syndrome. Anterior lens capsule PXF material and iridocorneal pigment of 98 untreated patients with PXF syndrome/glaucoma were graded from photographs and correlated with untreated IOP and indices of glaucoma severity (cup to disc ratio, and visual field mean deviation, and pattern standard deviation). There was a positive statistically significant correlation between the iridocorneal angle pigmentation and IOP (P=0.047, R2=0.2), but not the indices of glaucoma severity (P>0.13). There was no significant correlation between the anterior lens capsule PXF material and IOP or the indices of glaucoma severity (P>0.42). The grade of angle pigmentation, but not lens PXF, in eyes with IOP >21 mm Hg was significantly higher than in eyes with IOP < or =21 mm Hg (P=0.04). In patients with PXF syndrome/glaucoma, gonioscopically identified iridocorneal angle pigmentation correlates more strongly with presenting IOP than the amount of PXF material on the anterior lens capsule.
