Purpose: Pseudoexfoliation syndrome (PEX) is an age-related systemic elastic fibrillopathy disorder featuring an excessive production and accumulation of elastic fibre components in the extracellular matrix and is associated with impaired protective mechanisms against oxidative and cellular stress. PEX is diagnosed solely by ophthalmologists; however, PEX deposits have been detected in the connective tissues of many extraocular organ systems. This large, retrospective case-control study investigates whether patients with PEX have an increased risk of extraocular comorbidities. Methods: Cases and controls were drawn from consecutive patients over 50 years of age undergoing in-house ophthalmological operations under general anaesthesia or in standby preparedness for general anaesthesia. The participants were grouped based solely on PEX-positive (n = 325) or PEX-negative (n = 911) status. The same teams of ophthalmologists and anaesthesiologists uniformly documented every known systemic comorbidity of each patient through two independent rounds of standard anamnestic procedure and protocols in preparation for general anaesthesia. For the purpose of this study, every systemic comorbidity was registered from these forms and subsequently categorized into 17 disease groups based on the International Classification of Diseases (ICD-10) of the World Health Organization (WHO). Odds ratios (ORs) comparing comorbidities in cases and controls were adjusted for age and gender using logistic regression. Results: After adjustment for multiple testing, patients with PEX had an increased odds ratio for respiratory OR 2.1 [1.4; 3.0], cardiac OR 2.5 [1.6; 4.2], vascular OR 2.0 [1.4; 2.8], and urogenital conditions OR 2.3 [1.4; 3.7]. Renal and psychiatric comorbidities were nominally significant. While no substantially higher frequency was found for hernias, aneurysms, aortic dissection, or varicose veins among PEX-positive patients, higher rates of cardiac valve disorders and benign prostate hyperplasia were found among the PEX-positive individuals. Conclusion: In addition to confirming an increased risk of respiratory, cardiovascular, and urogenital comorbidities, our data found an increased risk of cardiac valve disorders and benign prostate hyperplasia among PEX-positive patients, which may be manifestations of the underlying systemic elastotic fibrillopathy and warrants further exploration, including future histological study.
