ABSTRACT: Background: Zygomatic fracture is one of
the most prevalent one among facial fractures caused by vehicle accident,
motorcycle accident, fighting, fall and sport injuries. Materials &
Methods: This study was a retrospective study of our patients during past 6
years. Results: We had 1277 facial fractures, of whom 9 patients had blindness.
We had 193 patients with Zygomatic fracture. 98 patients had pure zygomatic
fracture and other had complicated fractures. Frequency of blindness due to
zygomatic fracture in a period of six years was 4.7% in all and in pure
zygomatic fractures was 2.04%. Blindness was most prevalent in age group 20 -
29 years old (55.6%). The most prevalent cause of zygomatic fracture which
causes blindness, was motor vehicle accident (77.8%). Blindness was more common
in males (77.8%) than females (22.2%). Discussion and Conclusions: One of the
most disastrous complication of zygomatic fracture is transection of optic
nerve. Very careful examination of fractured bones careful examination of optic
nerve and visual acuity and urgent operation and decompression of optic nerve
must be performed. About 4% - 5% will have blindness purely due to fracture.
