Analysis of 1246 Cases of Orbital Lesions: A Study of 17 Years

Abstract

Purpose: The aim of this study is to present an analysis of orbital lesions by classifying them according to the site of origin in patients of all ages presenting at a tertiary care eye hospital from 1996 till 2012. Methods: 1637 patients were initially enrolled in this descriptive case series. Clinical data of 1246 patients who completed the study during 17 years were analyzed. Orbital lesions of the patients were examined and managed medically or surgically as per requirement. The histopathological reports of these patients were used to classify the lesions. Results: Out of all cases 54.57% (n = 680) were neoplastic and 45.42% (n = 566) were nonneoplastic lesions. Amongst the neoplastic lesions 86.17% (n = 586) were malignant and 13.82% (n = 94) were benign. Primary orbital lesions were the most common orbital lesions being 963 (77.29%) followed by secondary orbital lesions being 232 (18.62%), hematopoietic reticuloendothelial being 47 (3.77%) and metastatic lesions being 04 (0.32%). Conclusion: Orbital lesions are more common in adults as compared to children. Neoplastic lesions are more common than nonneoplastic lesions, and amongst the neoplastic lesions malignant lesions are more common than benign ones. Primary orbital lesions are the most common orbital lesions followed by secondary orbital lesions, lesions of the hematopoietic reticuloendothelial system and metastatic lesions.
