The Clinical Analysis Of Visual Prognosis Factors In Intraocular Foreign Bodies

Intraocular foreign bodies were a major cause of open ocular traumaresulting in impairment of visual function. It was more difficult to assess thevisual prognosis preoperly in the intraocular foreign bodies, because of thevariable factors such as patients’ gender, age, injury reason, properties offoreign bodies. Analysis of intraocular foreign bodies would give guidance topeople to take precautions to reduce the incidence of intraocular foreignbodies, meanwhile help to assess the injury and provide a basis for the furtherimplementation of the treatment means.PURPOSETo investigate epidemiologic and clinical characteristics,prognosticfactors,and visual outcomes of posttraumatic intraocular foreign body.METHODS373eyes of370consecutive patients who were treated for intraocular foreign bodies injury during2009.1-2014.8in the in-patient department of the second hospital of Jilin University were retrospectively analyzed. Gender, age, mechanism of injury, presenting visual acuity, characteristics of wound and foreign bodies, tracmatic cataracts, retinal hole, retinal detachment, vitreous hemorrhage, proliferative vitreoretinopathy andendophthalmitis were evaluated, followed by a comparison of outcomes and investigation of the relationship between the prognosis and the factors mentioned above.RESULTS373eyes of370patients enrolled, of which190cases were right eyes,177cases left one and binocular3cases. There were359cases of were maleand11cases females.The incidence of intraocular foreign bodies weresignificantly higher in the workplace than in the community. The mechanismof injuries was hammering in196（196/373,52.6%）,cutting in72（72/373,19.3%）, chiseling47（47/373,12.6%）, Blast in25（25/373,6.7%）,firecrackers in14（14/373,3.8%）, puncture11（11/373,2.9%）, weldding3（3/373,0.8%）, down-falling in3（3/373,0.8%）and car accident in2（2/373,0.5%）.Follow up time ranged from8to14months (mean10.2months).Unfavorable postoperative best corrected visual acuity (BCVA)＜0.05wasrelated to older than50year（sP＜0.05）, lower0.3of presenting visual acuity,length of wound more than10mm（P＜0.05）, irregular shape of wound（P＜0.05）,the interval from injuries to repair more than24hours, non-magnegicforeign bodies（P＜0.05）, retinal hole（P＜0.05）, retinal detachment（P＜0.05）, vitreous hemorrhage（P＜0.05）, proliferative vitreoretinopathy（P＜0.05） and endophthalmitis （P＜0.05）,extracting foreign bodies byvitrectomy（P＜0.05）, and more than one operation procedure due of vitreousbody（P＜0.01）. Patients with presenting visual acuity more than0.3couldhave good prognosis, as well as younger than50years（P＜0.05）.The wound length of4mm or less（P＜0.05）, regular shape and self-sealing of wound（P＜0.05）, magnegic foreign bodies less than4mm located in the anteriorsegment（P＜0.05）, no retinal hole（P＜0.05）, no retinal detachment（P＜0.05）, no vitreous hemorrhag（eP＜0.05）, no proliferative vitreoretinopathy（P＜0.05）and no endophthalmitis（P＜0.05）, extracting foreign bodies bymagnet（P＜0.05）, and only one operation procedure（P＜0.05）may havepostoperative eyesight improved.CONCLUSIONSYounger men were admitted to our hospital form2009～2014because ofthe intraocular foreign bodies.Education and instruction for people wereneeded in case of injuries because of lacking of protective measures generally.Prognosis are related to age, presenting visual acuity, length and shape ofwound and24hours self–sealing or not, length, type and location of theforeign boodies, traumatic cataract, retinal hole,retinal detachment, vitreoushemorrhage,proliferative vitreoretinopathy,endophthalmitis, surgical approachand number of operations.The independent risk factors for visual prognosisinclude age, presenting visual acuity, length of foreign bodies, retinal hole andmultiple surgeries.
