This was a one year descriptive-cases-series of proptosis presenting to a tertiary eye clinic between January to December 2011. Socio- demographic data were obtained. Subjects aged between 41/ years to 2 75 years who had proptosis referred from the Otorhinolaryngology clinics were examined. Visual acuities, clinical examination of the anterior and posterior segment of the eye, ocular alignment and systemic examination were done. Otorhinolaringologists' findings, laboratory results, radio diagnostic tests, and previous surgical intervention were noted. The major causes of proptosis were due to malignancy (66%) followed by infections and cystic lesions in equal proportions. Half of the subjects who developed visual impairment had improvement in vision and improved facial symmetry after appropriate treatments were instituted. Cases of strabismus were also corrected. Co- management is here demonstrated to give the best cosmetic and visual outcome.Keywords: Otolaryngological causes, proptosis, visual impairmen
