要約 目的:滲出型加齢黄斑変性(AMD)に対するアフリベルセプト硝子体内投与(IVA)の長期成績について検討する。
対象と方法:対象は未治療の典型AMD,ポリープ状脈絡膜血管症(PCV)と診断され,初回治療としてIVAを単独で行い,3年以上経過観察できた52例54眼。IVAは3回の導入期の後,症例ごとの状況を踏まえた維持期投与を行った。IVAの1年後,3年後,最終受診時の視力および中心窩網膜厚(CRT),IVA施行回数,合併症について検討した。
結果:症例は,典型AMD22眼,PCV32眼。平均経過観察期間はそれぞれ,46.0±11.6か月,52.4±10.8か月。1年後,3年後,最終視力は,典型AMDではすべて治療前と比較して有意差がなく,PCVでは3年目までは有意に改善していたが,最終受診時には治療前と有意差がなくなった。平均CRTは典型AMD,PCVともにすべての時期で,治療前より有意に減少していた。平均IVA施行回数はそれぞれ16.1±10.0回,15.1±9.6回であった。経過中,感染や網膜剝離,脳梗塞などの合併症は認められなかった。
結論:初回治療としてIVAを選択し,3年以上にわたり経過観察ならびにIVAで治療できた症例において視力の維持ができた。
Abstract Purpose:To investigate the long-term results of intravitreal aflibercept(IVA)for neovascular age-related macular degeneration(AMD).
Subjects and Methods:Subjects were 54 eyes of 52 patients who had been diagnosed with untreated typical AMD or polypoidal choroidal vasculopathy(PCV), who were treated with IVA alone as the initial treatment with follow up period for 3 years and more. IVA was administered in the maintenance phase based on the situation of each case after the 3 injections as induction phases. Visual acuity(VA)and central retinal thickness(CRT), number of IVA performed, and complications were evaluated at one year, three years and last visit of follow up.
Results:The cases included typical AMD 22 eyes and PCV 32 eyes. The average follow-up period was 46.0±11.6 months and 52.4±10.8 months, respectively. VA at 1 and 3 years and final visit was not significantly different from baseline VA in typical AMD eyes. VA in PCV eyes significantly improved by the 3rd year, but not significantly at the last visit. CRT decreased significantly in both typical AMD and PCV at all evaluation points compared to baseline. The average IVA frequency was 16.1±10.0 and 15.1±9.6 respectively. During the course, no serious adverse events such as ophthalmitis, retinal detachment, or cerebral infarction were observed.
Conclusion:IVA maintained visual acuity for more than 3 years.
