要約 目的:未熟児網膜症(ROP)瘢痕期に血管新生緑内障,および脈絡膜新生血管を生じた稀な症例を経験したので報告する。
症例:2歳3か月,男児。在胎週数26週2日,780gで出生した。修正33週で両眼にaggressive ROP(A-ROP)を発症し,翌日両眼にラニビズマブ硝子体内注射を施行した。修正36週時に全周に広範に網膜光凝固術を施行したが,修正49週時に左網膜の新生血管増殖を認め,硝子体内注射を再度施行した。以降鎮静化していたが,2歳3か月時に左眼の充血,瞳孔散大,高眼圧をきたし,国立成育医療研究センターへ紹介となった。左虹彩上に血管新生,蛍光眼底造影で虹彩と周辺部網膜耳上側に蛍光色素漏出を認めたことから血管新生緑内障と診断し,網膜光凝固の追加とアフリベルセプト硝子体内注射,およびマイクロパルス毛様体光凝固術を行った。術後3か月目に左眼圧が再上昇し,虹彩新生血管の残存があったため,再度毛様体光凝固術を施行した。また,両眼に脈絡膜新生血管を認めた。
結論:A-ROPの抗血管内皮増殖因子療法後には,血管新生緑内障,脈絡膜新生血管を生じる可能性があり,再燃を念頭に置いた長期的な眼底管理が必要である。
Abstract Purpose:We report a rare case of neovascular glaucoma and choroidal neovascularization occurring during the cicatricial stage of retinopathy of prematurity(ROP) following anti-vascular endothelial growth factor(anti-VEGF) therapy.
Case:A 2-year-3-month-old boy, born at 26 weeks of gestation with a birth weight of 780 g, developed bilateral aggressive ROP(A-ROP) at a corrected age of 33 weeks. He received bilateral intravitreal ranibizumab injections, followed by extensive retinal photocoagulation at 36 weeks. At 49 weeks, the left eye required an additional intravitreal ranibizumab injection for recurrent neovascularization. At 2 years 3 months of age, he presented with left-eye hyperemia, mydriasis, and elevated intraocular pressure. Examination revealed iris neovascularization, and fluorescein angiography demonstrated vascular leakage, confirming neovascular glaucoma. Treatment included additional retinal photocoagulation, intravitreal aflibercept injection, and micropulse cyclophotocoagulation. Three months postoperatively, residual iris neovascularization persisted in the left eye, requiring repeat cyclophotocoagulation. Choroidal neovascularization was subsequently observed in both eyes.
Conclusion:In patients with A-ROP treated with anti-VEGF therapy, neovascular glaucoma and delayed-onset choroidal neovascularization may develop during the cicatricial phase. Long-term fundus monitoring is therefore essential.
