Acute Ocular Pain Following Endoscopic Mastectomy: A Case Report

Endoscopic breast surgery (EBS) is a widely adopted minimally invasive technique that offers improved cosmetic outcomes and faster recovery. However, the use of carbon dioxide insufflation can occasionally result in unexpected complications. We report a rare case of acute postoperative ocular pain with suspected transient intraocular pressure elevation following EBS in a healthy 36-year-old female. The symptoms were likely due to CO₂ diffusion into subcutaneous tissue and Trendelenburg positioning, which contributed to venous congestion and elevated episcleral venous pressure. Conservative management led to full symptom resolution within 24 hours. This case underscores the importance of intraoperative vigilance and awareness of atypical postoperative symptoms.
