RESUMEN
To assess the frequency and severity of ophthalmic injuries in patients with orbito-zygomatic fractures. A case series. Oral and Maxillofacial Department, KEMU/Mayo Hospital Lahore, from January 2009 to December 2011. Patients with orbito-zygomatic fractures were divided into three groups. Group-1 patients had fracture of floor/medial wall of the orbit [orbital-blow out fracture]. Group-2 had comminuted orbito-zygomatic fractures. Group-3 had simple zygomatic bone fractures. Frequency and types of ocular injuries were determined on each group. There were 296 [260 male, 36 female] patients with mean age of 31.7 years. Group-1 [n = 20] had 28 ocular findings in 12 [60%] patients including diplopia [n = 10, 36%], enophthalmos [n = 6, 14%], and hyphema, vitreous hemorrhage, retinal hemorrhage, choroidal rupture, traumatic mydriasis, and commotio retinae in 2 cases, 7% each. In Group-2 [n = 106], 44 ocular findings were identified in 30 [28%] patients including diplopia [n = 10, 23%], enophthalmos [n = 4, 9%], commotio retinae [n = 10, 23%], reduced visual acuity [n = 6, 14%], retinal hemorrhage [n = 4, 9%] and corneal laceration, corneal abrasion, retinal detachment, traumatic mydriasis, and canthal laceration in 2 cases, 4.5%. In Group-3 [n = 170], 22 ocular findings were seen in 16 [9%] patients included diplopia [n = 10, 45%], enophthalmos [n = 4, 18%], and retinal tear, hyphema, angle recession, and traumatic mydriasis in 2 cases, [9%] each. Ophthalmic injuries are a common complication of orbitozygomatic fractures occurring in about 20% of patients in this study, most frequent in the orbital blow fractures subgroup. Ophthalmology consultation is recommended for patients presenting with midface fractures
