Point prevalence of pseudoexfoliation syndrome in patients scheduled for cataract surgery in eye camps in Yemen

To study the point prevalence of pseudoexfoliation syndrome [PXS] among Yemeni patients in different governorates with age-related cataract scheduled for surgery. Eye camps organized by the Nibras Health Society to perform cataract surgeries during the years 2002-2006. All patients aged 40 years and above were included in the study. A total of 2535 eyes of 2535 patients from 13 governorates, scheduled for cataract surgery in eye camps, were included. All eyes underwent complete eye examination before the surgery and were evaluated for the signs of pseudoexfoliation material in the pupil, iris and lens capsule on dilated slit lamp examination. The study found 495 of the 2535 eyes [19.53%] with PXS with males more commonly affected than females [55.2 and 44.8%, respectively]. The mean age of patients with PXS was 66.2 years while it was 64.6 years in non-PXS patients. The prevalence of pseudoexfoliation syndrome increased with age [10.1% in the age group of 41-50 years that increased to 28.8% in the age group of more than 81 years old]. The rate of PXS detection in camps in 13 governorates ranged from 13.33 to 24.22% with an overall rate of 19.53%. The lowest rate was noticed in Sana'a and the highest in Al-Dhale governorate. This pilot study confirms that PXS was common in patients undergoing cataract surgery in Yemen with an increased detection rate with age. This study also highlights the prevalence of an ocular disease that is associated with systemic and ocular complications? however, further studies based on population studies are needed
