Modern ophthalmic literature presents information about pseudoexfoliation syndrome (PES) as a systemic pathological process. Ocular PES itself does not lead to visual acuity reduction and does not cause negative subjective feelings. However, PES remains an urgent problem due to high prevalence of ocular manifestations, high frequency of combination with age-related cataract and glaucoma as well as with retinal pathology, high myopia, which adversely affects their clinical course and results of treatment. The prevalence of PES increases with age. The paper is dedicated to clinical and statistical analysis of the ocular PES in age-related cataract in the residents of the Tambov Region, and is performed on the basis of a retrospective cohort study of the archival case histories of patients with age-related cataract ― 124448 patients, 19726 (15,85%) patients, diagnosed with PES. The age of all examined patients ranges from 45 to 84 years old (67.2±10.5). In accordance with the nomenclature of WHO (1990) 17640 people (14.2%) belong to middle age; 32716 people (26.3%) ― elderly age; 74092 (59.5%) ― senile age. The index of ocular PES prevalence (according to appealability) is calculated per 1000 examined patients with age-related cataract. The total index of the ocular PES among patients with age-related cataract, living on the territory of Tambov region is 158 cases per 1000 patients. The data obtained do not exceed the indices of PES prevalence in age-related cataract that are registered in population living in the European part of Russia. A slight predominance of PES in men (165 cases) is noted as compared to women (155 cases) per 1000 examined patients with age-related cataract. An increase in PES frequency in senile patients ― up to 194 cases per 1000 people with age-related cataract is observed; in elderly patients ― up to 130 compared to 62 cases per 1000 examined patients with age-related cataract in the middle age group.

Key words: pseudoexfoliation syndrome, age-related cataract, regional demographic peculiarities.
