【摘要】:目的: 觀察累及黃斑區(qū)孔源性視網(wǎng)膜脫離經(jīng)玻璃體切割術(shù)(pars planavitrectomy,PPV)治療后,黃斑區(qū)形態(tài)特征,探索視力預(yù)后與黃斑區(qū)細(xì)微結(jié)構(gòu)變化的關(guān)系。 方法: 觀察我院眼底病外科自2012年10月-2013年9月確診為孔源性視網(wǎng)膜脫離并經(jīng)裂隙燈下眼底檢查或頻域光學(xué)相干斷層掃描(spectral-domain optical coherence tomography,SD-OCT)檢查證實脫離范圍累及黃斑區(qū)、臨床上符合玻璃體手術(shù)指征患者,行一次玻璃體切割手術(shù)達(dá)到視網(wǎng)膜復(fù)位,且隨訪資料完整者20人20眼。手術(shù)前及手術(shù)后眼部檢查包括:雙目間接眼底鏡、最佳矯正視力(best correctedvisual acuity,BCVA)、裂隙燈顯微鏡、頻域OCT檢查。應(yīng)用SD-OCT測量患者黃斑中心凹視網(wǎng)膜厚度及外核層(outer nuclear layer,ONL)厚度,并觀察黃斑區(qū)細(xì)微結(jié)構(gòu)的改變,分析術(shù)后視力與上述改變的關(guān)系;以患者黃斑區(qū)視網(wǎng)膜脫離時間[26]作為分組標(biāo)準(zhǔn),比較不同脫離時間對術(shù)后視力是否有影響。 結(jié)果: 1.以黃斑區(qū)視網(wǎng)膜脫離時間(黃斑區(qū)脫離的癥狀:即中心視力缺失[26、27、28、29],持續(xù)時間定義為從上述癥狀出現(xiàn)至實施手術(shù)時間[26、27、28、29]。)6天為界,分為兩組:A組小于等于6天組,術(shù)后視力logMAR值0.415±0.225;B組大于6天組,術(shù)后視力logMAR值0.741±0.250;術(shù)后視力logMAR值受黃斑區(qū)視網(wǎng)膜脫離時間影響存在明顯差異(P=0.008≤0.05),黃斑區(qū)脫離時間短的患者獲得良好術(shù)后視力;對兩組IS/OS連續(xù)性分析: A組:連續(xù)8眼,不連續(xù)0眼;B組:連續(xù)5眼,不連續(xù)7眼?ǚ诫p側(cè)檢驗p=0.015≤0.05,單側(cè)檢驗p=0.010≤0.01。即A組IS/OS連續(xù)性好于B組。 2.術(shù)后ONL厚度、與術(shù)后視力logMAR值相關(guān)(r=0.678,p=0.001≤0.05);對二者行線性回歸,得線性回歸方程:術(shù)后視力logMAR值=0.006×ONL+0.032,即本組病例中:ONL越薄,術(shù)后視力越好?刂菩g(shù)前視力,對ONL厚度與手術(shù)前后視力logMAR值變化行偏相關(guān)分析,發(fā)現(xiàn)ONL厚度與手術(shù)前后視力logMAR值變化相關(guān)(r=0.697,p=0.001≤0.05),,對二者行線性回歸,得線性回歸方程:手術(shù)前后視力logMAR值變化=0.005×ONL+0.878×術(shù)前視力logMAR值+0.153,即:ONL越薄,術(shù)前視力越差,手術(shù)前后視力變化越明顯。 3.術(shù)后黃斑中心凹視網(wǎng)膜厚度與術(shù)后視力logMAR值中度相關(guān)(r=0.446,p=0.049≤0.05),對二者行線性回歸,得線性回歸方程:術(shù)后視力logMAR值=0.003×中心凹視網(wǎng)膜厚度-0.094,即:黃斑中心凹視網(wǎng)膜厚度越薄,術(shù)后視力越好;控制術(shù)前視力,對黃斑中心凹視網(wǎng)膜厚度與手術(shù)前后視力變化logMAR值行偏相關(guān)分析,發(fā)現(xiàn)黃斑中心凹視網(wǎng)膜厚度與手術(shù)前后視力變化logMAR值無關(guān)(r=-0.424,p=0.07>0.05); 4.術(shù)后光感受器細(xì)胞接頭處(photoreceptor inner segment/outersegment,IS/OS)形態(tài)影響:IS/OS不連續(xù)(7眼,35%);IS/OS交界線連續(xù)(13眼,65%)。結(jié)果表明:術(shù)后視力logMAR值受IS/OS斷裂與否影響顯著(T=2.609,p=0.018≤0.05);黃斑中心凹厚度受IS/OS斷裂與否影響顯著(T=2.098,p=0.050≤0.05)。 5.術(shù)后外界膜(external limiting memrane, ELM)形態(tài)影響: ELM不連續(xù)(9眼,45%)、ELM連續(xù)(11眼,55%)。結(jié)果表明:ELM斷裂與否對術(shù)前視力logMAR值、術(shù)后視力logMAR值、黃斑區(qū)脫離時間、外核層(ONL)、中心凹視網(wǎng)膜厚度等均無顯著影響。 結(jié)論: 1.黃斑區(qū)脫離時間影響術(shù)后視力,在黃斑區(qū)脫離6天內(nèi)積極治療可以獲得更好的預(yù)后視力及IS/OS連續(xù)性。 2.術(shù)后視力與術(shù)后黃斑區(qū)細(xì)微結(jié)構(gòu)IS/OS的完整性、黃斑區(qū)中心凹視網(wǎng)膜厚度、ONL厚度有關(guān)。
[Abstract]:Purpose :
Objective To investigate the morphological features of macular area and to explore the relationship between visual acuity and subtle changes in macular area after treatment with vitrectomy ( PPV ) .
Method :
Objective To observe the relationship between visual acuity and the change of macular area after operation and post - operative eye examinations , including binocular indirect ophthalmoscopy , best corrected visual acuity ( BCVA ) , slit lamp microscope and frequency domain OCT .
The retinal detachment time of the macular region of the patient was determined as the grouping criterion , and the effect of different detachment time on postoperative visual acuity was compared .
Results :
1 . The symptoms of retinal detachment time in the macular area ( i.e . , the central vision loss was 26 , 27 , 28 , 29 ) . The duration was defined as the range from the above symptoms to the operative time ( 26 , 27 , 28 , 29 ) . The duration was defined as two groups : group A was less than or equal to 6 days , and the postoperative visual logMAR value was 0.415 鹵 0.225 ;
The postoperative visual logMAR value was 0.741 鹵 0.250 .
The postoperative visual logMAR value was significantly different from the time of retinal detachment in macular area ( P = 0.008 鈮
