Prevalence of ocular pseudoexfoliation syndrome and associated complications in Riyadh, Saudi Arabia.

OBJECTIVES: To assess the prevalence of pseudoexfoliation syndrome (PEX), and associated ophthalmic complications among Saudi patients. METHODS: The prevalence of PEX and associated ocular co-morbidities were determined among the Saudi patients visiting the Primary Care Clinic of Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia, between January 2009 and January 2010. A total of 1967 patients were examined biomicoscopically by ophthalmologists to determine the presence of PEX and associated ocular complications. RESULTS: Sixty-nine of the 1967 examined patients (3.5%) showed the presence of PEX with no significant gender difference. There was an age dependent increase in the prevalence of PEX after the age of 50 years. Pseudoexfoliation syndrome was associated with higher intraocular pressure, cataract, and poor vision. There was no significant difference in the prevalence of PEX in male and female Saudi patients. CONCLUSION: Pseudoexfoliation syndrome is an age-related disorder, and its prevalence increases with age. Further larger population based studies are warranted to assess the prevalence of PEX and associated risk factors.
