Background/Objectives: We aimed to evaluate the demographic characteristics, clinical findings, and survival outcomes of patients diagnosed with orbital metastasis, considering primary tumor type, age, and gender variables. Methods: In this observational study, demographic data, tumor localization, histopathological diagnoses, and survival times of 83 patients followed for secondary orbital metastasis at Çukurova University Ophthalmology Department between 2003 and 2023 were retrospectively reviewed. Subgroup analyses were performed according to age (<18 and ≥19), gender, and primary tumor groups. Results: The study included 83 patients (51 (61.4%) females and 32 (38.6%) males). The mean age at diagnosis was found to be 40.8 ± 24.6 years. A total of 24.1% of the cases were in the pediatric age group (mean age 5.9 years), and the most common tumor metastasizing to the orbit in this group was neuroblastoma (80%). In adult patients, the two most frequent tumors metastasizing to the orbit were breast cancer (33.3%) and lung cancer (14.3%). The most common clinical findings were proptosis (32.5%) and blurred vision (26.2%). Orbital metastases were observed more frequently in females than in males (61.4% vs. 38.6%). This ratio was similar in the pediatric age group (65.0% vs. 35.0%). The mean survival time after metastasis was calculated as 316.7 ± 68.6 days. Female patients had a significantly longer survival time after metastasis compared to males (mean 400.4 vs. 165.4 days; p = 0.037). The median survival after metastasis was 86 days for patients with breast cancer and 204 days for patients with neuroblastoma. Conclusions: The most common source of orbital metastases in females is breast cancer, while neuroblastoma is prominent in pediatric patients. Despite all available treatment options, the prognosis after orbital metastasis is poor; this highlights the importance of early diagnosis and a multidisciplinary approach.
