Abstract:

Objective To study the etiological,  clinical characteristics and prevention strategies of children with intraocular foreign body(IOFB).Design Retrospective case series. Participants One hundred and seventy inpatients of Beijing Tongren Hospital with IOFB during January 1 2004 to December 31 2016 with age of 1 to 14 years old (mean8.73±3.12years),  among whom 157 were boys(92.4%). Method The basic information of patients,  causes of injury,  wounds,  eye complications,  IOFB characteristics,  surgical treatment and prognosis were collected and analyzed using SPSS. Main Outcome Measures Cause of the injury,  type of foreign body,  complications and blindness rate.Results Among the causes of the injury,  explosive injuries was the most common (59.4%,  n=101),  followed by sharp stick injuries (20.6%,  n=35). Fireworks were the most damaging items (41.2%,  n=70),  followed by detonators (8.8%,  n=15). Endophthalmitis occurred in 35  cases (25.0%). Retinal tears or detachment occurred in 96 cases (56.5%). 140  cases (82.4%) of foreign bodies located in the posterior segment. 148 cases (87.1%) underwent vitrectomy. 105 patients (61.8%) were blind (best corrected visual acuity<0.05) after operation. Blast injury patients had higher blinding rates than other causes of injury (72.3% vs 46.4%,  P<0.01). Conclusions The most common cause of injury in children with IOFB is explosion.Fireworks are the most damaging items.The vision prognosis is poor in children with IOFB.（Ophthalmol CHN,  2018, 27：150-154）
