Various tumors can involve the orbital space. Although orbital tumors are rare, these sight-threatening and possibly life-threatening disorders consist of a broad disease spectrum. The purpose of the study is to determine the prevalence of orbital tumors presenting in a tertiary eye care centre and evaluate their Demographic pattern and Clinical findings. This cross-sectional descriptive study was conducted in the Department of Oculoplasty, Ispahani Islamia Eye Institute & Hospital from August 2019 to July 2020. 30 patients were selected of all age and sex presented with primary orbital tumors during study period. All patient was examined properly. Their demographic, clinical, radiological and histopathological data was collected. Total 30 patients meet the inclusion criteria. Among them 8 cases were diagnosed by clinical & radiological examinations. Twenty two (22) cases were diagnosed by histopathology. Among 30 diagnosed patients 16 patients were male and 14 patients were female. Age range of 30 patients were 1 months to 60 years. 1-10 years category 13 patients, 11-20 years 4 patients, 21-30 years 1 patients, 31-40 years 3 patients, 41-50 years 0 patients and 50+ years 9 patients. 09 patients were diagnosed as malignant neoplasm and other 21 patients were diagnosed as benign neoplasm. Among 9 malignant neoplasms 8 cases are diagnosed as NHL and rest one was Adenoid cystic carcinoma. Among 21 benign cases 6 were diagnosed as dermoid cyst, 4 cases were diagnosed as orbital lymphangioma, 2 cases were diagnosed as orbital capillary hemangioma, 2 cases Optic nerve glioma and plexiform neurofibroma, optic nerve meningioma, pleomorphic adenoma, schwannoma, glomus tumor, Langerhans cell histiocytoma, cavernous hemangioma one case each. The age distribution of diagnosed 30 patients exhibited two peaks, at 0 to 10 years (13 patients) and 50+ years (9 patients). In the 0- to 9-year-old patients, the most common tumors were dermoid cyst 6 patients and in 50+ years patient age group most common diagnosis was NHL (8 patients). The most common sign and symptom were proptosis (76.66%), palpable mass (73.33%) and restricted ocular movement 46.66%. A wide range of tumors can involve the orbit. The prevalence of malignant tumors increased with age, and in younger age group vascular and cystic tumors are more common. Most common malignancy is NHL occurs in older age group and most common benign orbital tumor is dermoid cyst occurs in younger age group. Among all tumors proptosis, palpable mass and restricted movement was the most common presenting features.
