  • Abstract
  • Look Inside

A 25-year-old female was referred to us with a 9 -month history of epiphora and conjunctival injec-tion in her right eye. She also noted progressive exophthalmos since 4 months before. Her visualacuity was 20/20 in either eye. The right eye was proptotic by 5 mm. Slight constriction in the tempo-ral visual field was present in the right eye. Plain skull x-ray and computed tomography showed a calcified mass in the right ethmoidal sinus extend-ing into the right orbit. The excised mass was very solid and measured 32×36×24 mm. Histopathology showed it to be an orbital osteoma with dense bone formation. This case seemed to illustrate the impor-tance of epiphora and conjunctival injection as early clinical signs of orbital osteoma originating from the ethmoidal sinus.
