眼外肌在近视中的作用研究分析 眼科医学专业VIP免费

题目：眼外肌在近视中的作用研究眼外肌是附着于眼球外部的肌肉，每眼各有6条，按其走行方向分直肌和斜肌，本次实验主要研究了眼外肌在兔子形觉剥夺性近视中的作用研究，通过比较近视屈光度的变化与眼轴长短的变化，探讨眼外肌和近视的关系。首先，将2-3周健康雄兔24只，随机分为3组，每组8只：白兔组右眼形觉剥夺组(1-8)、A组眼睑缝合组(A1-A8)、B组眼部直肌断腱处理组(B1-B8)。其次，三组均通过形觉剥夺来诱导近视。造模后，均用新缘牌FA-6500型电脑验光仪和A/B超仪分别检测眼睛的屈光度和眼轴长度，通过对屈光度和眼轴长度的比较，研究眼外肌对屈光度和眼轴长度的影响，从而研究对近视的影响。从实验所得结果表明，白兔的右眼屈光度和眼轴长度明显发生变化，青紫兔的右眼的屈光度和眼轴长度虽然没有体现出差异，但有向近视发展的趋势，而且B组的这种趋势要小于A组。所以我们可以得出的结论是：白兔也可以通过形觉剥夺建造近视动物模型，眼外肌对近视没有显著的影响。关键词眼外肌近视造模形觉剥夺毕业论文外文摘要Title：TheroleofextraocularmusclesinmyopiaAbstractTheextraocularmusclesareattachedtotheoutsideofthemusclesoftheeye,eacheyehas6,accordingtoitsdirectionofthebranchmuscleandobliquemuscle,thisexperimentmainlystudiedtheextraocularmuscleinrabbitshapedeprivationmyopiaintheroleofresearch,bycomparingthechangesinmyopiadiopterandthelengthoftheaxiallength,toexploretherelationshipbetweenextraocularmuscleandmyopia.First,24healthymalerabbitswererandomlydividedinto3groups(n=8):righteyeshapedeprivationgroup(1,8),groupAeyelidsuturegroup(A1-A8)GroupBoculomotortendontreatmentgroup(B1-B8).Second,thethreegroupsthroughtheformofdeprivationtoinducemyopia.Afterthemodelwasestablished,therefractionandaxiallengthoftheeyeweremeasuredwiththenewmarginFA-6500computerandtheA/Bsuper-meterrespectively.Bycomparingthediopterandthelengthoftheaxiallength,Axislengthoftheimpact,soastostudytheimpactofmyopia.Theresultsoftheexperimentshowthattherighteyerefractionandaxiallengthofthewhiterabbitsareobviouslychanged.Therefractionandaxiallengthoftherighteyeofthepurplerabbitdonotshowthedifference,butthereisatrendtowardsthedevelopmentofmyopia.ThetrendislessthantheAgroup.Sowecanconcludethat:whiterabbitscanalsobedeprivedoftheconstructionofmyopicanimalmodel,theextracorporealmusclehasnosignificantimpactonmyopia.KeyWords：ExtraocularmuscleMyopiaModelingFormdeprivation目录1引言.............................................................11.1近视形成机制...................................................21.2近视模型的建立方法.............................................51.3模型动物的选择.................................................51.4诱导方法的改善.................................................72实验材料.........................................................82.1实验动物.......................................................82.2试剂与仪器.....................................................82.3实验用具.......................................................82.4实验的前期准备工作.............................................83实验方法.........................................................93.1建立形觉剥夺性近视模型.........................................93.2实验方案......................................................113.3实验具体操作步骤..............................................113.4屈光度的测量..................................................133.5眼轴长度的测量................................................133.6模型的检测....................................................143.7...
