목적: 나이관련황반변성에 합병된 맥락막신생혈관과 결절맥락막혈관병증에서 광역학치료 및 베바시주맙의 병합치료의 효과를 비교하였다. 대상과 방법: 삼출성 나이관련황반변성(AMD군) 또는 결절맥락막혈관병증(PCV군)으로 진단받은 환자를 대상으로 광역학치료와 베바시주맙 유리체강내주입술 병합치료를 시행하였다. 베바시주맙 유리체강내주입술은 광역학치료 후 2주 이내에 시행하였으며, 이후4-6주 간격으로 2회를 추가로 시행하였고 치료 후 시력과 중심부황반두께 및 재주사 회수를 조사하였다. 결과: AMD군이 21명(평균66.8세)이었으며 PCV군은 17명(평균66.4세)이었다. 평균경과관찰은 17.0개월이었다. 평균시력은 AMD군에서술전 logMAR 0.75에서 12개월에 0.49로 상승하였으며(p=0.01), PCV군에서는 술전 0.81에서 12개월에 0.63으로 상승하였다(p=0.03). 중심부황반두께는 AMD군에서 329 μm에서 231로, PCV군에서 354에서 223로 각각 유의하게 감소하였다. 시력이 유지 또는 상승한눈은 12개월에 AMD군에서 20안(95.2%), PCV군에서 15안(88.2%)이었다. 평균 재주사 횟수는 AMD군에서 4.3회, PCV군에서 3.0회였다. 시력, 시력의 변화, 중심부황반두께 및 재주사 횟수에서 두 군 사이 유의한 차이는 없었다. 결론: 삼출성 나이관련황반변성과 결절맥락막혈관병증에서 광역학치료와 베바시주맙 유리체강내주입술의 병합요법은 시력의 유지 및추가치료의 측면에서 두 군 사이 유의한 차이를 보이지 않았다.
Abstract
Purpose: To compare the efficacies of photodynamic therapy (PDT) using verteporfin combined with intravitreal bevacizumab in choroidal neovascularization secondary to age-related macular degeneration and polypoidal choroidal vasculopathy (PCV). Methods: Photodynamic therapy followed by 3 monthly intravitreal injections of bevacizumab were performed for neovascular age-related macular degeneration (AMD group) and PCV (PCV group). The injections were performed within 2weeks after PDT and then every 4 to 6 weeks. During the 12-month follow-up period, best-corrected visual acuity (BCVA),central subfield macular thickness (CSMT), and number of reinjections were reviewed retrospectively. Results: Out of 38 eyes, there were 21 eyes in the AMD group (mean age 66.8 years old) and 17 eyes in the PCV group (mean age 66.4 years old). The average follow-up duration was 17.0 months. At 12 months, the BCVA (logMAR) improved from 0.75 at baseline to 0.49 in the AMD group (p = 0.01) and from 0.81 to 0.63 in the PCV group (p = 0.03). The CSMT decreased significantly from 329 to 231 in the AMD group and from 354 to 223 in the PCV group. At 12 months, 20 eyes (95.2%) in the AMD group and 15 eyes (88.2%) in the PCV group increased or maintained BCVA. The numbers of reinjections were 4.3 in the AMD group and 3.0 in the PCV group. There were no significant differences in BCVA, BCVA changes, CSMT, or number of reinjection between the two groups. Conclusions: Combined PDT and intravitreal bevacizumab injections showed no significant difference in stabilization of vision or retreatment rates between neovascular age-related macular degeneration and PCV.
