要約 目的:視力が良好な滲出型加齢黄斑変性(AMD)にぺガプタニブナトリウムの硝子体注射を行った結果の報告。対象と方法:AMD 7例7眼を対象とした。男性4例,女性3例で,年齢は63~84歳(平均77歳)であり,矯正視力はすべて0.5以上であった。ペガプタニブナトリウム0.3mgを硝子体に注入し,6か月までの経過を追った。結果:投与回数は2~5回(平均3.7回)であった。6か月後の視力は全例で維持または改善したが,治療前と比べ有意差はなかった(p=0.22)。光干渉断層計(OCT)で測定した6か月後の網膜厚は,4眼で減少または不変,3眼で増加したが,治療前と比べ有意差はなかった(p=0.88)。全経過を通じ,眼または全身の副作用はなかった。結論:視力が良好なAMDに対するペガプタニブナトリウムの硝子体注射により,6か月間の視力が維持される可能性がある。
Abstract. Purpose:To report 6-month outcome of intravitreal injection of pegaptanib sodium for exudative age-related macular degeneration(AMD)with good visual acuity. Cases and Method:This study was made on 7 eyes of 7 patients with AMD. The age ranged from 63 to 84 years and averaged 77 years. Their corrected visual acuity was 0.5 or over. Each eye received intravitreal injection of 0.3 mg pegaptanib sodium. They were followed up for 6 months or longer. Results:Treatment was repeated 2 to 5 times,average 3.7 times. Visual acuity after 6 months remained stable or better in all the eyes. The difference from the pretreatment level was not significant(p=0.22). Central retinal thickness,as measured by optical coherence tomography(OCT),decreased or remained unchanged in 4 eyes and increased in 3 eyes. The difference from the pretreatment level was not significant(p=0.88). There was no ocular or systemic complication throughout the study. Conclusion:Intravitreal injection of pegaptanib may result in maintaining visual function in eyes with AMD with initially good visual acuity.
