“…Cumulative effects of these multiple fractures could have some adverse effect to orbital content and specially and more importantly, optic nerve. One of the disastrous complications of zygomatic fracture or its neglected side effects is blindness [2] …”

“…Among these patients cause of blindness maybe transection of nerve with sharp bone particles or sometimes due to compression of optic nerve in optic canal by bony fragments or increase intra ocular or intra orbital pressure [2] [9] [13] [19]. In some papers blindness was reported as a complication after secondary reconstruction for zygomatic fracture and most frequently due to displaced bone graft [18].…”

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.

“…These span a range of mechanisms, clinical courses, and ultimate outcomes ranging from traumatic blindness following a displaced lateral orbital wall fracture to traumatic retrobulbar hemorrhages and malar fractures. [13][14][15][16] Other interesting yet rare complications have been published in the form of transient complete blindness following nose blowing after an orbital floor fracture and orbital cellulitis secondary to fracture with subsequent subperiosteal abscess formation and permanent blindness. [17][18][19] The facial skeleton is designed to withstand large force loads, with directed energy resistance in the form of elasticity, surrounding periosteum, and affect of soft tissues.…”

Craniomaxillofacial Trauma & Reconstruction

View full text Add to dashboard Cite

Blindness is an uncommon, yet documented complication of facial trauma. Numerous case studies, series, and retrospective analyses have been published, with a reported incidence around 3%. Hippocrates first noted the association between maxillofacial trauma and blindness; millennia later, this was expounded upon by Berlin, who discovered such trauma may directly lead to fracturing of the optic canal. As diagnostic modalities such as computed tomographic scanning evolved, particularly over the past few decades, more specific, in-depth reports analyzing maxillofacial trauma and subsequent sequelae have emerged. It is the goal of this article to examine the current literature for those publications that have addressed the issue of blindness following facial trauma (including operative interventions) and create a concise review for maxillofacial surgeons.

“…Even rarer mechanisms for blindness than facial fracture are direct injury to the optic nerve caused by retrobulbar hemorrhage either postinjury or postfracture repair fracture of the optic canal, penetrating foreign body, and bony fragments impinging on the optic nerve. 2 Complete visual loss caused solely by posterior lateral wall fragments impinging on the intraorbital portion of the nerve in the orbital apex is very uncommon. To our knowledge, only two previous case reports exist.…”
