病理性近視眼目前尚無特異性治療方法,主要進(jìn)行屈光矯正及低視力康復(fù),如出現(xiàn)并發(fā)癥則對癥治療。

Atpresent,thereisnospecifictreatmentforpathologicalmyopia,mainlyrefractivecorrectionandlowvisionrehabilitation,andsymptomatictreatmentifcomplicationsoccur.

病理性近視的治療思路,首先是矯正屈光不正,可以通過配戴框架眼鏡、角膜接觸鏡、角膜屈光手術(shù)或有晶體眼人工晶體植入

手術(shù)。

Thetreatmentideaofpathologicalmyopia,thefirstistocorrecttherefractiveerror,canbebywearingframeglasses,cornealcontactlenses,cornealrefractivesurgeryorintraocularlensimplantationsurgery.

對于進(jìn)展性近視,如有需要可以行后鞏膜加固手術(shù)。

另外,病理性近視患者,容易發(fā)生并發(fā)性白內(nèi)障,如發(fā)生白內(nèi)障,可以行白內(nèi)障手術(shù)治療;發(fā)生視網(wǎng)膜脫離,可以行激光治療或

視網(wǎng)膜脫離修復(fù)手術(shù)治療;對視網(wǎng)膜下新生血管膜及黃斑出血者,采取抗VEGF治療、激光治療及光動力學(xué)治療等。

康復(fù)Rehabilitation

近視力康復(fù):患者雙眼的最佳矯正近視力均為0.2,考慮患者需要經(jīng)常批改作業(yè)及閱讀需求,由于患者舒適閱讀的視力需求為4.5(0.3)-4.6(0.4),40cm視力為4.3(0.2),如提高到4.6(0.4),則閱讀距離移到20cm,則需要5.0D的調(diào)節(jié)。Nearvisionrehabilitation:Thebestcorrectednearvisioninbotheyesofthepatientswas0.2.Consideringthatthepatientsneededtocorrecthomeworkandreadfrequently,andsincethevisualrequirementforcomfortablereadingis4.5(0.3)-4.6(0.4),andthevisualacuityof40cmis4.3(0.2),ifthereadingdistanceisimprovedto4.6(0.4),5.0Dadjustmentisrequiredwhenthereadingdistanceismovedto20cm.康復(fù)Rehabilitation因此,提高近視力的方法有以下幾種:Therefore,thereareseveralwaystoimprovenearvision:①雙眼近用處方OD-14.00/-1.00×90;OS-9.00/-2.50×90,視力可以達(dá)到0.5。②采用上述提及的單眼視屈光矯正(一只眼看遠(yuǎn),一只眼看近):OD-14.00/-1.00×90;OS-14.00/-2.50×90。③雙眼仍然在40cm處看近,OD-14.00/-1.00×90;OS-14.00/-2.50×90(遠(yuǎn)用處方),此時左右眼近視力均4.3(0.2),再采用4x鎮(zhèn)紙式放大鏡視力可以達(dá)到4.8(0.6);或者采用帶超長臂自由活動放大鏡視力可達(dá)4.6(0.4)。①PrescriptionOD-14.00/-1.00×90fornearuseofbotheyes;OS-9.00/-2.50×90,visioncanreach0.5.②Usethemonocularrefractivecorrectionmentionedabove(oneeyefar,oneeyenear):OD-14.00/-1.00×90;OS-14.00/-2.50x90.③Botheyesarestilllookingcloseat40cm,OD-14.00/-1.00×90;OS-14.00/-2.50×90(distantprescription),atthistime,thenearvisionoftheleftandrighteyesare4.3(0.2),andthevisionofthe4xpaperweightmagnifyingglasscanreach4.8(0.6);Oruseafreemovingmagnifyingglasswithanextralongarmtoachieveavisionof4.6(0.4).建議患者近用眼鏡式助視器(批改作業(yè)、閱讀等)、鎮(zhèn)紙式放大鏡(閱讀)、帶長臂放大鏡(批改作業(yè))配合使用。對于電子產(chǎn)品的閱讀,可以使用手機(jī)或電腦本身的放大軟件APP,以及手機(jī)設(shè)置中的字體大小,選擇特大字體。Itisrecommendedthatpatientsusecloseglasses(correctinghomework,reading,etc.),paperweightmagnifyingglass(reading),andmagnifyingglasswithlongarm(correctinghomework)together.Forthereadingofelectronicproducts,youcanusetheenlargingsoftwareAPPofthemobilephoneorcomputeritself,aswellasthefontsizeinthemobilephoneSettings,selectalargefont.康復(fù)Rehabilitation

疾病介紹Introductiontodisease第三部分

Part3三、疾病介紹Diseaseintroduction病理性近視是因眼軸過度增長而造成的眼底后極部損害為特征的高度近視,它有以下幾個特征:眼軸不斷增長,眼球后極部向后擴(kuò)張形成后鞏膜葡萄腫;近視度數(shù)隨年齡增長不斷增加;造成眼球后極部視網(wǎng)膜與脈絡(luò)膜的損害。Pathologicalmyopiaisahighmyopiacharacterizedbydamagetotheposteriorpoleofthefunduscausedbyexcessivegrowthoftheaxisoftheeye.Ithasthefollowingcharacteristics:theaxisoftheeyecontinuestogrow,andtheposteriorpoleoftheeyeballexpandsbackwardtoformposteriorscleralstaphyloma;Thedegreeofmyopiaincreasedwithage,

causingdamagetotheretinaandchoroidoftheposteriorpoleoftheeyeball.視力的減退可因并發(fā)性白內(nèi)障、視網(wǎng)膜脫離、脈絡(luò)膜新生血管等引起。病理性近視是我國引起低視力的主要病因之一,患者屈光度多在-10.00D以上甚至達(dá)-40.00D。我國是世界上近視眼最多的國家之一,目前我國高中生近視患病率達(dá)80%以上,病理性近視在人群中的患病率為1%~2%、隨著兒童青少年近視發(fā)病年齡提前、進(jìn)展增快,病理性近視的比率仍將上升,病理性近視導(dǎo)致的低視力風(fēng)險也隨之增加。Thelossofvisioncanbecausedbycomplicatedcataract,retinaldetachment,choroidalneovascularizationandsoon.PathologicalmyopiaisoneofthemaincausesoflowvisioninChina,andthediopterofpatientsismorethan-10.00Doreven-40.00D.Chinaisoneofthemostnearsightedcountriesintheworld,atpresent,theprevalenceofmyopiainhighschoolstudentsinourcountryismorethan80%,theprevalenceofpathologicalmyopiainthepopulationis1%~2%,withtheonsetofmyopiainchildrenandadolescents,therateofpathologicalmyopiawillcontinuetorise,andtheriskoflowvisioncausedbypathologicalmyopiawillalsoincrease.低視力特點(diǎn)Characteristicsoflowvision這些患者由于戴高屈光度的負(fù)透鏡,而使得視網(wǎng)膜成像顯著縮小、看遠(yuǎn)處物體時似乎更遠(yuǎn)一些,屈光不正-10.00D以上時,視網(wǎng)膜成像顯著縮小、發(fā)生辨認(rèn)困難,因而有些患者不愿意接受眼鏡。若出現(xiàn)眼底等病變,矯正視力無法提高。Thesepatientsworenegativelenseswithhighdiopter,whichmadetheretinalimagesignificantlysmallerandappearedfartherawayfromdistantobjects,refractiveerrorsexceeding-10.00Dresultinsignificantretinalimagingreduction,leadingtodifficultiesinrecognition.病理性近視后期,各種并發(fā)癥導(dǎo)致矯正視力無法提高。Advancedstagesofpathologicalmyopiacancausecomplicationsthatpreventimprovementincorrectedvision.不戴鏡可獲得較好的近視力,但患者的遠(yuǎn)點(diǎn)太近,如-15.00D的近視,遠(yuǎn)點(diǎn)在眼前6.7cm,長時間在6.7cm距離近讀易發(fā)生疲勞和工作不便。Goodmyopiamightbeattainablewithoutglasses,farpointsintheaffectedeyearetooclose.Forinstance,with-15.00Dmyopia,thefarpointisapproximately6.7cminfrontoftheeye,causingfatigueandinconvenienceduringprolongedclosereadingwithadistanceof6.7cminfrontoftheeye.屈光矯正原則Theprincipleofrefractivecorrection病理性近視所致的低視力在康復(fù)方面的首要措施是仔細(xì)進(jìn)行屈光檢查,配戴合適的眼鏡,改善遠(yuǎn)視力。Thefirststepsinrehabilitationoflowvisionduetopathologicalmyopiaaretaking
