Txhawm rau txiav txim siab txog qib ntawm residual internal limiting membrane (ILM) tom qab idiopathic epiretinal membrane (ERM) tev thiab cov txiaj ntsig ntawm staining nrog ci ntsa iab GA yav tom ntej, multicenter, kev soj ntsuam ntawm 98 lub qhov muag undergoing pars plana vitrectomy thiab membrane peeling rau idiopathic ERM.Txhua lub qhov muag tau txais kev kho mob tseem ceeb (20, 23, lossis 25 gauge) ua raws li intravitreal triamcinolone los xyuas kom meej tias cov hyaloid tom qab tau raug tshem tawm.Brilliant xiav G (0.2 mL ntawm 0.25 mg / mL) tau txhaj rau hauv lub vitreous kab noj hniav thiab ntxuav tam sim ntawd.ERM raug muab tshem tawm thiab tom qab ntawd tus kws phais tau pom thiab sau cov yam ntxwv ntawm ILM hauv qab.Cov ncej tom qab tau khaws cia nrog ci ntsa iab xiav G (0.2 mL ntawm 0.25 mg / mL), thiab tib qhov kev soj ntsuam ntawm cov yam ntxwv ntawm ILM tau sau tseg.Kev tshem tawm ntawm qhov seem ILM tau ua.Qhov txiaj ntsig tseem ceeb ntsuas yog qhov xwm txheej ntawm ILM tom qab ERM tev.Cov txiaj ntsig thib ob suav nrog kev kho qhov muag pom qhov pom zoo tshaj plaws thiab lub hauv paus macular tuab ntawm 6 lub hlis tom qab ua haujlwm.Tom qab ERM tev, tag nrho cov qhov muag muaj qhov seem ILM.Hauv 74 lub qhov muag, ILM tau tshwm sim thiab puas lawm, thaum nyob rau hauv 24 lub qhov muag, ILM tam sim no thiab tsis muaj kev puas tsuaj.Hauv 37 lub qhov muag, tus kws phais neeg ua haujlwm tsis tuaj yeem txiav txim siab txog qhov xwm txheej ntawm ILM ua ntej ci ntsa iab G staining.Thaum 6 lub hlis, lub logarithm ntawm qhov tsawg kawg nkaus lub kaum sab xis ntawm qhov kev daws teeb meem zoo tshaj plaws-kho pom kev pom kev zoo tuaj ntawm 0.75 ± 0.39 ntawm lub hauv paus rau 0.31 ± 0.26 (P <0.0001).Lub hauv paus macular tuab kuj tau txhim kho los ntawm 460 ± 91 μm ntawm lub hauv paus mus rau 297 ± 102 μm (P <0.003).Internal limiting membrane feem ntau tseem tam sim no tom qab ERM tev tawm.Staining nrog ci ntsa iab G pab txhawb nws cov cim.
