Prevalence of Pseudoexfoliation Syndrome in Turkish Patients with Senile Cataract

To investigate the prevalence of pseudoexfoliation syndrome (PEX) among Turkish patients with senile cataract.

Records of 352 eyes of 352 patients who underwent cataract surgery were analyzed in this retrospective study. The presence of PEX, type of cataract, intraocular pressure (IOP), glaucoma, age-related macular degeneration, and systemic diseases (coronary artery disease, hypertension, diabetes mellitus) were recorded.

The overall prevalence of PEX syndrome was detected to be 11%. The mean age of PEX patients was significantly higher than without PEX (74.4 ± 7.2 years and 69.3 ± 11.4 years, respectively, p = 0.004). The most common cataract type in the PEX patients was mixed-type cataract determined in 51.2% of patients. IOP was significantly higher in eyes with PEX than in eyes without it (16.1 ± 4.5 mmHg and 14.7 ± 3.8 mmHg, respectively; p = 0.03). Moreover, the prevalence of age-related macular degeneration was found to be significantly higher, and prevalence of glaucoma slightly higher in PEX patients than without PEX.

Pseudoexfoliation syndrome is a common condition in Turkish people. PEX is associated with mixed type of cataract, age-related macular degeneration, and elevated IOP. Therefore, PEX patients should be checked for concomitant diseases.
