Purpose: To report two cases of orbital apex syndrome caused by blunt orbital trauma without structural damage of the orbit.
Case summary: (Case 1) A 50-year-old male came to our clinic complaining of visual loss after blunt orbital trauma by a metal bar. The best-corrected visual acuity was no light perception and light reflex was not observed in the affected eye. He also presented with complete ptosis and ophthalmoplegia with relative sparing of adduction and depression. High signal intensity of the orbital soft tissue including the optic nerve sheath was revealed using a T2-weighted image in magnetic resonance imaging. After starting steroid pulse therapy, his visual acuity improved to counting fingers on the third day. Ocular movement and levator function recovered to the normal range while visual acuity remained counting fingers. (Case 2) A 64-year-old female presented with complete ptosis after trauma to her right eyeball. The best-corrected visual acuity was 20/25 in the right eye. Complete ptosis and ophthalmoplegia with relative sparing of abduction and depression in the right eye were observed at the initial presentation. Magnetic resonance images showed enhancement of the right periphery optic nerve and distal rectus muscle. Two months after undergoing steroid pulse therapy, levator function and ocular movement recovered completely, and visual acuity improved to 20/20.
Conclusions: The orbital apex syndrome caused by blunt orbital trauma showed good response to steroid pulse therapy. Steroid treatments may therefore be considered for the treatment of traumatic orbital apex syndrome.
