2006年3月第42卷第3期ChinJOphthalmol,March2006,Vo142,No.3甲状腺相关眼病的放射治疗罗清礼何为民唐莉陈礼金【摘要】目的探讨甲状腺相关眼病(TAO)放射治疗的适应证和临床效果。方法选择1992至2004年在I~lJII大学华西医院肿瘤科放射治疗室行眼眶照射、资料较齐全的23例TAO患者,其中9例是浸润性突眼、14例是压迫性视神经病变,均为糖皮质激素治疗不敏感、不能接受糖皮质激素治疗者,或者因较严重的糖尿病、高血压等不能做眼眶减压或不愿意做手术的活动期且病程短的TAO患者。采用直线加速器和Donaldson眼眶外照射法,照射野大小为4cm×5cm,放射总剂量为20GY,治疗分10次,每次2GY。放射治疗期间其中11例炎性反应较重的患者同时口服泼尼松。全部患者放射治疗前后均行外眼照像和眼眶cT检查。结果14例压迫性视神经病变,放射治疗前矫正视力0.04~0.2,放射治疗后矫正视力0.1~0.8,CT检查显示肿大的眼外肌缩小,眼外肌缩小的程度与视力提高的程度成正相关。9例浸润性突眼,放射治疗前眼部炎性反应明显,放射和口服泼尼松治疗后眼睑、结膜肿胀显著减退,眶压降低,眼睑能闭合,暴露性角膜炎痊愈,眼球活动受限好转,眼球突出度降低1~3mm。随访1~3年,3例患者又出现视力减退,4例眼眶炎性反应复发,2例眼睑仍部分闭合不全。结论活动性难治的TAO患者采用放射治疗效果较好,对于眼眶炎性反应严重的患者可加用糖皮质激素治疗。f中华腰科杂志,2006,42:218-221【关键词】格雷夫斯病;放射疗法;糖皮质激素类Radiationtherapyforthyroid·associatedophthaimopathyL∞Qng-li,舰Wei-min,ⅣG厶,CHENl_i-jin.DepartmentofOphthalmology。HuaxiHospital,S~huanUniversity,Chengdu61004l,ChinaCorrespondingauthor:LUOQing-li.Email:luo-qingli@263.net【Abstract】ObjectiveToobserveindicationandefectivenessofradiationtherapy(RT)inthetreatmentofthepatientswiththyroid.associatedophthalmopathy(TAO).Methods23patientsofTAOwhoreceivedRTinSichuanUniversitywerecollectedfroml992to2O04.Amongthosepatients.9casesofinfiltrativeexophthalmosand14casesofcompressiveopticneumpathywereinefectivelywithuc0conicoidtreatmentorcouldnottreatedwithglucocorticoid。orcouldnotperformorbitaldecompressionduetoseverediabeticmelitusorhypertesion,orfearedtoreceivetheoperation,allofpatientswereactiveophthalmopathyandwithshortduration.OuterorbitalradiationwasappliedusinglinearacceleratorwithDonaldsonsmethod。radiationtreatmentfieldswas4cm×5cm。exposureengerywas2GYfractionswithtotalof20GInl1caseswithsevereinflammationprednisonewasadmistratedduringradiotherapy.PhotosandCTscanweretakenforeachpatientbeforeandafterRT.ResultsVisualacuity(VA)ofthepatientswasimprovedfrombeforeRT0.04.2toafterRT0.1.8in14casesofcompressiveopticneumpathy.ExtraocularmuscleofpatientsdicreasedinsizeconfirmedbyCTscan.VAimprovementwascorrelatedwiththedegreeofextraocularmuscledicreasedinsize.Eyelidandconjunctivesweling。eyelidincompletelyclosure。exposurekeratitis。limitationofmotionandproptosiswereimpmvedafterRTin9patientswithinfiltrativeexophthalmos.Followingupthepatientsforl-3years.itwasfoundthatVAdecreasedin3casesandinfiammationrecurredin4cases.eyelidscouldnotclosedin2casesafterRT.CondusionsRTcouldbeusedinsevere。activecasesofTA0.Ifthereissevereinfiammation。steroidscouldbecombinedwithRTtherapy.(chinJOphthMmol,2006,:218-221【Keywords】Gravesdisease;Radiotherapy;Glucocorticoids基金项目:国家自然科学基金资助项目(30371518);高等学校博士学科点专项科研基金资助项目(C200057);四川省科技攻关项目资助项目(01SG046-l1)作者单位:610041成都,四川大学华西医院眼科(罗清礼、何为民、唐莉),肿瘤科(陈礼金)通讯作者:罗清礼,Email:luo-qin~i@263.net.论著....
