ABSTRACT
INTRODUCTION:
Pseudoexfoliation (PEX) syndrome is a common, age-related disease which is associated with the multifocal deposition of fibrillar PEX material in intra- and extraocular tissues. Subsequently among others second chronic open-angle glaucoma and corneal endothelial cell loss occurs. The present study analysed whether there is a correlation between the stage of the PEX process and corneal endothelial cell density (cECD), regardless of the non-existence or proof of secondary glaucoma. MATERIALS ANDMETHODS:
One eye of 109 Caucasian subjects (mean age 71.7 years) was examined by slit-lamp microscopy and classified based on visible PEX deposits on the lens (mild and severe) and presence of glaucoma in 4 study groups. The control groups were healthy subjects and patients with primary open angle glaucoma (POAG). The cECD was measured with the endothelial cell mirror microscope (SeaEagle).RESULTS:
All study groups and the POAG group showed a significant cECD reduction compared to the healthy control group POAG 6.0â%; PEX syndrome mild 5.5â% and severe 11.0â%, PEX glaucoma mild 7.7â% and severe 12.3â%. Further the cECD was significantly lower compared to the POAG group in severe PEX syndrome by 5.4â% and in severe PEX glaucoma by 6.8â%. cECD significantly decreased with increasing PEX stage independently of the presence of glaucoma. These differences remained statistically significant after Bonferroni-Holm correction. The analysis of the entire group of test subjects showed only a weak correlation between mean intraocular pressure and mean cECD.CONCLUSION:
The results of this study showed a decreasing cECD with increasing PEX stage, regardless of whether glaucoma is present or not. The influence of the PEX process appears to be more pronounced than the influence of intraocular pressure.
