Aim: We aimed to investigate changes in intraocular pressure (IOP) in patients who underwent chalazion surgery, specifically examining the impact of chalazion location, size, and site on the eyelid. Materials and Methods: Forty eyes with chalazia were included in this prospective study. Chalazia were categorized based on size (Group 1: 3-5 mm; Group 2: >5 mm), location on the eyelid (central, temporal, nasal), and eyelid site (upper, lower). Before surgery, all patients underwent a comprehensive biomicroscopic examination, IOP measurement using both a pneumotonometer and a Goldmann applanation tonometer (GAT), and central corneal thickness (CCT) assessment. All measurements were repeated at the 1-month postoperative follow-up. Results: Following chalazion surgery, a significant decrease in IOP was observed using both GAT (p=0.001) and pneumotonometry (p=0.035). No statistically significant difference was found between preoperative and postoperative CCT values (p=0.642). In Group 1 (3-5 mm), a significant postoperative decrease in IOP was observed (p=0.021). Furthermore, significant reductions in IOP measurements were noted in the upper eyelid group (p=0.003) and for centrally located chalazia (p=0.016). No significant correlation was found between changes in IOP measurements and changes in CCT. Conclusion: Chalazia may influence IOP measurements, particularly those obtained via GAT. Therefore, IOP values measured in the presence of a chalazion should be interpreted with caution; repeating measurements after chalazion treatment may provide a more reliable clinical assessment.
