Clinical analysis of 39ocular contusion cases

Abstract

：Objective To report thecommon reasons and the clinical signs of ocular contusion,and to evaluate the therapeuticeffectiveness.Methods Fifty-three contused eyes of 39 cases were studied and followed-upfor 3 to 12 months(averaged 7 months)on reasons,clinical signs,therapeutic methods andprognosis.Patients were treated by drugs or surgery according to the position and severityof the trauma and combined with the outcome of examinations such as fundus fluorescenceangiography(FFA),ultrasound biomicroscope (UBM),B scan ultrasonography,optical coherencetomograpby(OCT),visual evoked potential(VEP),etc.The therapeutic effectiveness wasevaluated and the prognosis as well as the correlative factors were analyzed.ResultsTrauma by the fist was the most common reason for ocular contusion which was followed byimpacting with objects,waffle accident and blast.Sixteen eyes were damaged only inanterior segment with signs of acute corneal abrasion andedema,hyphema,iridochoroiditis,traumatic mydriasis,angle recession,iridodialysis,choroidaldetachment,cataract with or without subluxation and dislocation.The posterior segment wasinvolved in 26 eyes which represented vitreous hemorrhage,commotion retina,retinal holeand detachment,choroidal rupture,optic disc edema and atrophy.The other 11 eyes wereinjured in both anterior and posterior segment.Before treatment,best corrected visualacuity(BCVA)of 17 eyes was less than 0.1,accounting to 32.08%.However,the visual acuity of51 eyes(96.23%)improved and 13 eyes(24.52%)acquired BCVA of 0.5 or better after treatmentby drug and surgery.41.18% patients who acquired effective treatment within 24 hours altercontusion got a BCVA of better than 0.5 at the last follow-up.Conclusions By effective andtimely treatment,visual acuity can improve in most contused eyes.The prognosis is relatedto the position and severity of the trauma as well as the treating time.Visual acuityprognosis is usually poor when the posterior segment complications happen aider contusion.
