要約 目的:黄斑下血腫を伴うポリープ状脈絡膜血管症(PCV)に対し,ラニビズマブとSF6の硝子体注入を行った結果の報告。対象と方法:過去14か月間にラニビズマブとSF6の硝子体注入を行った黄斑下血腫を伴うPCV 17例17眼を対象とした。男性14例,女性3例で,年齢は57~91歳(平均72歳)である。全例で6か月以上の経過を追った。結果:黄斑下血腫は全例で1週間で移動し,菲薄化した。術後視力は12眼(71%)で改善または不変,5眼(29%)で悪化した。悪化した5眼中4眼では,網膜色素上皮剝離が中心窩にあった。術後の中心窩網膜厚は有意に改善した(p<0.05)。術後の再出血は1眼に生じた。結論:黄斑下血腫を伴うポリープ状脈絡膜血管症(PCV)に対するラニビズマブとSF6の硝子体注入後に,視力が改善し,黄斑厚が減少した。網膜色素上皮剝離が中心窩にある症例では,成績が低かった。
Abstract. Purpose:To report the outcome of intravitreal injection of ranibizumab and sulfur fluoride for polypoidal choroidal vasculopathy(PCV)with subfoveal hematoma. Cases and Method:This study was made on 17 eyes of 17 cases who received intravitreal injection of ranibizumab and sulfur fluoride for polypoidal choroidal vasculopathy(PCV)with subfoveal hematoma in the past 14 months. The series comprised 14 males and 3 females. The age ranged from 57 to 91 years, average 72 years. All the cases were followed up for 6 months or longer. Results:Subfoveal hematoma removed and attenuated within one week in all the eyes. Visual acuity improved or remained unchanged in 12 eyes(71%)and deteriorated in 5 eyes(29%). Detachment of retinal pigment epithelium(RPE)was present in the fovea in 4 out of the 5 eyes. Foveal thickness decreased significantly after treatment(p<0.05). Subfoveal hemorrhage recurred in one eye. Conclusion:Visual acuity improved and foveal thickness decreased after intravitreal injection of ranibizumab and suffur fluoride. The treatment was of limited value in eyes with RPE detachment in the fovea.
