摘 要:目的 分析雷珠單抗治療濕性年齡相關(guān)性黃斑變性的視力改善和黃斑形態(tài)學(xué)變化之間的相關(guān)性。方法 選取2014年1月~2016年2月在西安交通大學(xué)第一附屬醫(yī)院行雷珠單抗治療的濕性年齡相關(guān)性黃斑變性患者43例(1眼/例)。觀察治療前后最佳矯正視力(BCVA)、黃斑中心凹厚度(CMT)及黃斑病變面積。分析視力改善與黃斑形態(tài)學(xué)變化之間的相關(guān)性。結(jié)果 治療3個(gè)月后,BCVA升高字母數(shù)(8.93±5.70)個(gè),CMT下降(115.35±56.24)μm,黃斑病變面積減少(2.04±0.65)mm2。治療3個(gè)月后,BCVA變化與CMT變化之間無(wú)相關(guān)性(r=-0.170,P>0.05);BCVA變化與黃斑病變面積改變之間無(wú)相關(guān)性(r=-0.101,P>0.05)。結(jié)論 雷珠單抗治療濕性AMD具有較好療效,提高患者視力,改善黃斑形態(tài)學(xué),視力改善與黃斑形態(tài)學(xué)變化之間無(wú)相關(guān)性。

Abstract:Objective To retrospectively analyze the correlations between visual acuity and macular morphology after ranibizumab therapy for the wet age-related macular degeneration. Methods From January 2014 to February 2016, 43 patients (1 eye/case) of wet age-related macular degeneration treated with ranibizumab in the First Affiliated Hospital of Xi'an Jiaotong University were selected. The best corrected visual acuity (BCVA), macular foveal thickness (CMT) and macular degeneration area were observed before and after treatment. Analyze the correlation between visual acuity improvement and morphological changes of the macula. Results After 3 months of treatment, the number of letters in BCVA increased (8.93±5.70), the CMT decreased (115.35±56.24)μm, and the area of macular lesion decreased (2.04±0.65) mm2. There was no correlation between BCVA changes and CMT changes after 3 months of treatment (r=-0.170, P>0.05); there was no correlation between BCVA changes and macular lesions (r=-0.101, P>0.05). Conclusion Ralmuzumab has a good effect in the treatment of wet AMD, improving vision and improving macular morphology, and there is no correlation between visual acuity improvement and macular morphological changes.

年齡相關(guān)性黃斑變性(age-related macular degeneration,AMD)是一種慢性進(jìn)展性的視網(wǎng)膜退行性病變,是50歲以上人群中的主要致盲性眼病,預(yù)計(jì)到2040年全球患病率近3億人[1]。AMD分為干性(占85%~90%)和濕性(占10%~15%)兩種類型。由于濕性AMD造成的視力損害大于干性AMD,故目前治療主要針對(duì)前者。濕性AMD病理改變是脈絡(luò)膜新生血管的形成,由血液、滲出液和細(xì)胞外液形成的脈絡(luò)膜-視網(wǎng)膜色素上皮細(xì)胞-視網(wǎng)膜混合物堆積導(dǎo)致黃斑增厚[2]。血管內(nèi)皮生長(zhǎng)因子在脈絡(luò)膜新生血管形成中起重要作用[3]。因此,抗血管內(nèi)皮生長(zhǎng)因子靶向治療濕性AMD具有顯著療效[4]。2006年美國(guó)食品與藥品管理局批準(zhǔn)雷珠單抗用于治療濕性AMD,2012年中國(guó)國(guó)家藥監(jiān)局批準(zhǔn)其用于治療濕性AMD。本研……
